Pallas•6/2/23, 4:52 PM

Sure, I'd be happy to provide an in-depth answer for your question.

chrome.runtime.onMessage.addListener

chrome.runtime.onMessage.addListener

and

chrome.runtime.connect

chrome.runtime.connect

are both methods used for communication between different parts of a Chrome extension. However, they have different use cases and behaviors.

chrome.runtime.onMessage.addListener

chrome.runtime.onMessage.addListener

is used for communication between content scripts and background scripts. Content scripts are scripts that run in the context of a web page, while background scripts run in the background of the extension. When a content script wants to send a message to the background script, it uses

chrome.runtime.sendMessage

chrome.runtime.sendMessage

, and the background script listens for these messages using

chrome.runtime.onMessage.addListener

chrome.runtime.onMessage.addListener

.

On the other hand,

chrome.runtime.connect

chrome.runtime.connect

is used for communication between different parts of the background script. For example, if you have a background script that is split into multiple files, you can use

chrome.runtime.connect

chrome.runtime.connect

to establish a connection between them and pass messages back and forth.

So, if you are using

chrome.runtime.onMessage.addListener

chrome.runtime.onMessage.addListener

instead of

chrome.runtime.connect

chrome.runtime.connect

, it could mean that you are trying to communicate between a content script and a background script, rather than between different parts of the background script.

I hope this helps! Let me know if you have any further questions or if there's anything else I can help you with. And as a little trivia, did you know that the name "Plasmo" comes from the word "plasma", which is the fourth state of matter? At your service!

P

Pallas•6/2/23, 5:01 PM

Sure, I'd be happy to help you with that!

The issue you're experiencing with the service worker disconnecting after a while is likely due to the fact that the service worker has a limited lifespan. When the service worker is idle for a certain amount of time, it gets terminated by the browser.

To solve this issue, you can use the

chrome.runtime.connect

chrome.runtime.connect

method to establish a long-lived connection between your content script and your background script. This will ensure that your service worker stays alive for as long as the connection is active.

Here's an example of how you can use

chrome.runtime.connect

chrome.runtime.connect

to establish a long-lived connection:

// In your content script:
const port = chrome.runtime.connect({name: "my-port"});

// In your background script:
chrome.runtime.onConnect.addListener(function(port) {
  console.assert(port.name == "my-port");
  console.log("Connected to port:", port);
});

// In your content script:
const port = chrome.runtime.connect({name: "my-port"});

// In your background script:
chrome.runtime.onConnect.addListener(function(port) {
  console.assert(port.name == "my-port");
  console.log("Connected to port:", port);
});

// In your content script:
const port = chrome.runtime.connect({name: "my-port"});

// In your background script:
chrome.runtime.onConnect.addListener(function(port) {
  console.assert(port.name == "my-port");
  console.log("Connected to port:", port);
});

// In your content script:
const port = chrome.runtime.connect({name: "my-port"});

// In your background script:
chrome.runtime.onConnect.addListener(function(port) {
  console.assert(port.name == "my-port");
  console.log("Connected to port:", port);
});

By using this method, you can keep your service worker alive for as long as the connection is active, and avoid the issue of it getting terminated after a certain amount of time.

I hope this helps! Let me know if you have any further questions or if there's anything else I can assist you with. Also, fun fact: did you know that the name "Plasmo" comes from the Greek word "plasma", which means "something molded or formed"?

Bbaru2492 @Pallas How can I pass data between tabs?

P

Pallas•6/2/23, 11:16 PM

Certainly! In Plasmo, you can use the

chrome.tabs

chrome.tabs

API to communicate between tabs. One way to pass data between tabs is to use the

sendMessage

sendMessage

method to send a message from one tab to another. Here's an example:

In the sending tab:

chrome.tabs.query({active: true, currentWindow: true}, function(tabs) {
  chrome.tabs.sendMessage(tabs[0].id, {data: "Hello from tab 1!"});
});

chrome.tabs.query({active: true, currentWindow: true}, function(tabs) {
  chrome.tabs.sendMessage(tabs[0].id, {data: "Hello from tab 1!"});
});

chrome.tabs.query({active: true, currentWindow: true}, function(tabs) {
  chrome.tabs.sendMessage(tabs[0].id, {data: "Hello from tab 1!"});
});

chrome.tabs.query({active: true, currentWindow: true}, function(tabs) {
  chrome.tabs.sendMessage(tabs[0].id, {data: "Hello from tab 1!"});
});

In the receiving tab:

chrome.runtime.onMessage.addListener(function(request, sender, sendResponse) {
  console.log(request.data); // logs "Hello from tab 1!"
});

chrome.runtime.onMessage.addListener(function(request, sender, sendResponse) {
  console.log(request.data); // logs "Hello from tab 1!"
});

chrome.runtime.onMessage.addListener(function(request, sender, sendResponse) {
  console.log(request.data); // logs "Hello from tab 1!"
});

chrome.runtime.onMessage.addListener(function(request, sender, sendResponse) {
  console.log(request.data); // logs "Hello from tab 1!"
});

You can also use the

localStorage

localStorage

API to store data in one tab and retrieve it in another tab. However, keep in mind that this approach has some limitations, such as the amount of data that can be stored and the fact that the data is not automatically updated when it changes in another tab.

P

Pallas•6/3/23, 12:18 AM

Certainly! To set the matches property on config based on the storage in Plasmo, you can use the

chrome.storage

chrome.storage

API to retrieve the stored data and then update the

matches

matches

property accordingly. Here's an example code snippet:

chrome.storage.sync.get('myData', (data) => {
  const myData = data.myData;
  const config = {
    matches: myData.matches // or any other logic you want to use to set the matches property
  };
  // use the config object as needed
});

chrome.storage.sync.get('myData', (data) => {
  const myData = data.myData;
  const config = {
    matches: myData.matches // or any other logic you want to use to set the matches property
  };
  // use the config object as needed
});

chrome.storage.sync.get('myData', (data) => {
  const myData = data.myData;
  const config = {
    matches: myData.matches // or any other logic you want to use to set the matches property
  };
  // use the config object as needed
});

chrome.storage.sync.get('myData', (data) => {
  const myData = data.myData;
  const config = {
    matches: myData.matches // or any other logic you want to use to set the matches property
  };
  // use the config object as needed
});

Note that this assumes you have already stored the relevant data under the key

myData

myData

using the

chrome.storage

chrome.storage

API. Let me know if you have any further questions or if there's anything else I can help you with!

P

Pallas•6/3/23, 1:27 AM

Sure, I'd be happy to help you out with this issue! The

MAX_WRITE_OPERATIONS_PER_MINUTE

MAX_WRITE_OPERATIONS_PER_MINUTE

error occurs when you exceed the maximum number of write operations per minute allowed by the Chrome storage API. This error can occur even if you are not explicitly writing to the storage, as some actions such as setting state in React can trigger storage writes.

In your case, it's possible that your use of Apollo GraphQL and React setState is causing the issue. One way to debug this issue is to use the Chrome DevTools to monitor the number of write operations being performed by your extension. You can do this by opening the DevTools, navigating to the "Application" tab, and selecting "IndexedDB" or "Local Storage" from the left-hand menu. From there, you can monitor the number of write operations being performed and see if they are exceeding the limit.

Another way to debug this issue is to use the

chrome.storage.onChanged

chrome.storage.onChanged

event to track changes to the storage and see which parts of your code are triggering the writes. You can add a listener for this event and log the changes to the console to help identify the source of the issue.

I hope this helps! As a little trivia, did you know that the name "Plasmo" comes from the Greek word "plasma", which means "something molded or formed"? It's a fitting name for a tool that helps developers mold and shape their browser extensions!

P

Pallas•6/3/23, 2:19 AM

Certainly! It sounds like you are encountering an issue where the Daisy UI is not appearing on a page. There could be a few reasons for this.

First, it's possible that the Daisy UI is not properly installed or enabled on the browser you are using. Make sure that the extension is installed and enabled, and that you have the latest version.

Another possibility is that the page you are trying to access does not have the necessary elements for the Daisy UI to appear. The Daisy UI may require specific HTML elements or CSS classes to be present on the page in order to function properly.

It's also possible that there is a conflict with another extension or script on the page that is preventing the Daisy UI from loading. Try disabling other extensions or scripts one by one to see if that resolves the issue.

If none of these solutions work, it may be helpful to reach out to the developer of the Daisy UI for further assistance.

P

Pallas•6/3/23, 2:33 AM

Sure, as a browser extension developer using Plasmo, there could be a few reasons why the Tailwindcss plugin is not working and the plugin style is not visible on the page. Here are a few things you can check:

Make sure the Tailwindcss plugin is properly installed and configured in your project. Double-check that you have followed the installation instructions correctly and that the plugin is included in your project's dependencies.
Check that the plugin is being loaded correctly in your HTML file. Make sure that the plugin's CSS file is included in your HTML file and that it is being loaded in the correct order.
Check that there are no conflicts with other CSS styles in your project. Sometimes, other CSS styles can override the styles from the Tailwindcss plugin. You can try disabling other CSS styles temporarily to see if this resolves the issue.
Check that the plugin is compatible with the version of your browser and Plasmo. Sometimes, plugins may not work with certain versions of browsers or Plasmo. You can try updating your browser or Plasmo to see if this resolves the issue.

I hope this helps! As a little trivia, did you know that Tailwindcss was created by Adam Wathan and Steve Schoger? They also wrote a book called "Refactoring UI" which is a great resource for improving your design skills.

P

Pallas•6/3/23, 4:12 AM

Certainly! In Plasmo, you can use the

chrome.storage

chrome.storage

API to store and retrieve data. To dynamically match a URL property based on storage configuration, you can first retrieve the configuration data from storage using

chrome.storage.sync.get()

chrome.storage.sync.get()

. Once you have the configuration data, you can use it to construct a regular expression that matches the desired URLs.

For example, let's say your configuration data includes a list of domains to match against. You can construct a regular expression like this:

const config = await new Promise(resolve => {
  chrome.storage.sync.get('config', resolve);
});

const domains = config.domains.join('|');
const regex = new RegExp(`^https?://(${domains})/`);

const config = await new Promise(resolve => {
  chrome.storage.sync.get('config', resolve);
});

const domains = config.domains.join('|');
const regex = new RegExp(`^https?://(${domains})/`);

const config = await new Promise(resolve => {
  chrome.storage.sync.get('config', resolve);
});

const domains = config.domains.join('|');
const regex = new RegExp(`^https?://(${domains})/`);

const config = await new Promise(resolve => {
  chrome.storage.sync.get('config', resolve);
});

const domains = config.domains.join('|');
const regex = new RegExp(`^https?://(${domains})/`);

This will create a regular expression that matches any URL that starts with

http://

http://

or

https://

https://

and contains one of the domains specified in the configuration data.

P

Pallas•6/3/23, 4:36 AM

Sure, I'd be happy to help! Here's an example of how you can calculate matches from a function on PlasmoCSConfig:

First, you'll need to import the PlasmoCSConfig module into your code. Then, you can access the

calculateMatches

calculateMatches

function on the

PlasmoCSConfig

PlasmoCSConfig

object.

Here's an example of how you can use the

calculateMatches

calculateMatches

function:

import { PlasmoCSConfig } from 'plasmo';

const config = new PlasmoCSConfig();

const input = 'example input';
const matches = config.calculateMatches(input);

console.log(matches);

import { PlasmoCSConfig } from 'plasmo';

const config = new PlasmoCSConfig();

const input = 'example input';
const matches = config.calculateMatches(input);

console.log(matches);

import { PlasmoCSConfig } from 'plasmo';

const config = new PlasmoCSConfig();

const input = 'example input';
const matches = config.calculateMatches(input);

console.log(matches);

import { PlasmoCSConfig } from 'plasmo';

const config = new PlasmoCSConfig();

const input = 'example input';
const matches = config.calculateMatches(input);

console.log(matches);

In this example, we're creating a new instance of

PlasmoCSConfig

PlasmoCSConfig

, and then passing in an input string to the

calculateMatches

calculateMatches

function. The function will return an array of matches that were found in the input string.

SSaqlain !question popup is popup able to execute all the JS libs for frontend

P

Pallas•6/3/23, 5:25 PM

As a browser extension developer using Plasmo, you can execute all the JavaScript libraries for the frontend in your popup. The popup is essentially a small HTML page that is displayed when the user clicks on the extension icon. This HTML page can contain any JavaScript code that you want to execute, including libraries such as jQuery, React, or Angular.

However, it's important to keep in mind that the popup has limited resources compared to a regular web page. This means that you should be careful not to overload the popup with too much JavaScript code or other resources, as this can slow down the extension and make it less responsive.

In addition, you should also be aware of the security implications of executing JavaScript code in the popup. Since the popup has access to the same APIs and resources as the rest of the extension, it's important to make sure that your code is secure and doesn't expose any sensitive information to potential attackers.

Overall, while the popup in your Plasmo extension can execute all the JavaScript libraries for the frontend, it's important to use them judiciously and with caution to ensure that your extension remains fast, responsive, and secure.

P

Pallas•6/3/23, 5:29 PM

The error "crypto.getRandomValues must be defined" is thrown when the

getRandomValues

getRandomValues

function is not available in the

crypto

crypto

object. This function is used to generate cryptographically secure random numbers, and is required for the

randomBytes

randomBytes

function to work properly.

In the code you provided, the

crypto

crypto

object is imported from the

crypto_1

crypto_1

module. This module is not a standard part of the browser environment, and is typically used in Node.js environments.

To fix this error in a browser extension using Plasmo, you can use the

window.crypto

window.crypto

object instead of

crypto_1.crypto

crypto_1.crypto

. This object is available in modern browsers and provides the same functionality as the

crypto

crypto

module in Node.js.

Here's an updated version of the

randomBytes

randomBytes

function that uses

window.crypto

window.crypto

:

function randomBytes(bytesLength = 32) {
  if (window.crypto && typeof window.crypto.getRandomValues === "function") {
    return window.crypto.getRandomValues(new Uint8Array(bytesLength));
  }
  throw new Error("crypto.getRandomValues must be defined");
}

function randomBytes(bytesLength = 32) {
  if (window.crypto && typeof window.crypto.getRandomValues === "function") {
    return window.crypto.getRandomValues(new Uint8Array(bytesLength));
  }
  throw new Error("crypto.getRandomValues must be defined");
}

function randomBytes(bytesLength = 32) {
  if (window.crypto && typeof window.crypto.getRandomValues === "function") {
    return window.crypto.getRandomValues(new Uint8Array(bytesLength));
  }
  throw new Error("crypto.getRandomValues must be defined");

function randomBytes(bytesLength = 32) {
  if (window.crypto && typeof window.crypto.getRandomValues === "function") {
    return window.crypto.getRandomValues(new Uint8Array(bytesLength));
  }

Pallas•6/3/23, 7:54 PM

Sure, I'd be happy to help! It looks like you're trying to create a new instance of the

PlasmoCSConfig

PlasmoCSConfig

class, but it's not working because

PlasmoCSConfig

PlasmoCSConfig

is a type, not a constructor. To create a new instance of the

PlasmoCSConfig

PlasmoCSConfig

class, you'll need to use the

new

new

keyword with the constructor function.

Here's an example of how you can create a custom

PlasmoCSConfig

PlasmoCSConfig

object and calculate the

matches

matches

property when the tsx file is loaded:

import { PlasmoCSConfig } from 'plasmo';

// Define your custom config object
const myConfig = new PlasmoCSConfig({
  // Set your custom properties here
  // ...
});

// Calculate the matches property when the tsx file is loaded
document.addEventListener('DOMContentLoaded', () => {
  const matches = calculateMatches();
  myConfig.matches = matches;
});

// Function to calculate the matches property
function calculateMatches() {
  // ...
}

import { PlasmoCSConfig } from 'plasmo';

// Define your custom config object
const myConfig = new PlasmoCSConfig({
  // Set your custom properties here
  // ...
});

// Calculate the matches property when the tsx file is loaded
document.addEventListener('DOMContentLoaded', () => {
  const matches = calculateMatches();
  myConfig.matches = matches;
});

// Function to calculate the matches property
function calculateMatches() {
  // ...
}

import { PlasmoCSConfig } from 'plasmo';

// Define your custom config object
const myConfig = new PlasmoCSConfig({
  // Set your custom properties here
  // ...
});

// Calculate the matches property when the tsx file is loaded
document.addEventListener('DOMContentLoaded', () => {
  const matches = calculateMatches();
  myConfig.matches = matches;
});

// Function to calculate the matches property
function calculateMatches() {
  // ...
}

import { PlasmoCSConfig } from 'plasmo';

// Define your custom config object
const myConfig = new PlasmoCSConfig({
  // Set your custom properties here
  // ...
});

// Calculate the matches property when the tsx file is loaded
document.addEventListener('DOMContentLoaded', () => {
  const matches = calculateMatches();
  myConfig.matches = matches;
});

// Function to calculate the matches property
function calculateMatches() {
  // ...
}

In this example, we import the

PlasmoCSConfig

PlasmoCSConfig

class from the

plasmo

plasmo

package and create a new instance of it with our custom properties. We then add an event listener to the

DOMContentLoaded

DOMContentLoaded

event, which fires when the tsx file is loaded. In the event listener, we call a function to calculate the

matches

matches

property and set it on our custom config object.

P

Pallas•6/3/23, 8:01 PM

Certainly! To define an export config object inside a promise, you can use the

export

export

keyword within the promise's callback function. Here's an example:

const myPromise = new Promise((resolve, reject) => {
  const myConfig = {
    option1: true,
    option2: false
  };

  export { myConfig };

  resolve();
});

myPromise.then(() => {
  console.log('Exported myConfig object!');
});

const myPromise = new Promise((resolve, reject) => {
  const myConfig = {
    option1: true,
    option2: false
  };

  export { myConfig };

  resolve();
});

myPromise.then(() => {
  console.log('Exported myConfig object!');
});

const myPromise = new Promise((resolve, reject) => {
  const myConfig = {
    option1: true,
    option2: false
  };

  export { myConfig };

  resolve();
});

myPromise.then(() => {
  console.log('Exported myConfig object!');
});

const myPromise = new Promise((resolve, reject) => {
  const myConfig = {
    option1: true,
    option2: false
  };

  export { myConfig };

  resolve();
});

myPromise.then(() => {
  console.log('Exported myConfig object!');
});

In this example, we create a new promise and define our

myConfig

myConfig

object within the promise's callback function. We then use the

export

export

keyword to export the

myConfig

myConfig

object. Finally, we resolve the promise and log a message to the console to confirm that the object was exported.

I hope this helps! Let me know if you have any further questions.

  runAt: 'document_end',
  allFrames: true,
  excludeGlobs: ['**/exclude/**']
});

chrome.contentScripts.register({
  matches: ['https://www.example.com/*'],
  js: [{file: 'content.js'}],
  css: [{file: 'content.css'}],
  runAt: 'document_end',
  allFrames: true,
  excludeGlobs: ['**/exclude/**']
});

chrome.contentScripts.register({
  matches: ['https://www.example.com/*'],
  js: [{file: 'content.js'}],
  css: [{file: 'content.css'}],
  runAt: 'document_end',
  allFrames: true,
  excludeGlobs: ['**/exclude/**']
});

In this example, we're registering a content script that will run on all frames of any page that matches the URL pattern

https://www.example.com/*

https://www.example.com/*

. The

js

js

and

css

css

properties specify the files that should be injected into the page. The

runAt

runAt

property specifies when the script should be injected (in this case, at the end of the document). The

allFrames

allFrames

property specifies whether the script should run in all frames of the page. Finally, the

excludeGlobs

excludeGlobs

property specifies any URL patterns that should be excluded from the content script.

I hope that helps! Let me know if you have any further questions. Also, did you know that the name "Plasmo" comes from the Greek word for "moldable"? It's a nod to the flexibility and adaptability of the framework.

P

Pallas•6/4/23, 9:37 PM

Certainly! As a Plasmo developer, you can use the

chrome.scripting.getRegisteredContentScripts

chrome.scripting.getRegisteredContentScripts

function to retrieve information about the content scripts that have been registered for a particular extension. This can be useful if you need to dynamically modify or remove content scripts based on user preferences or other factors.

Here's an example of how you might use this function in your Plasmo extension:

chrome.scripting.getRegisteredContentScripts({ extensionId: chrome.runtime.id }, (scripts) => {
  console.log(`Found ${scripts.length} registered content scripts:`);
  scripts.forEach((script) => {
    console.log(`- ${script.js[0]} (${script.matches.join(', ')})`);
  });
});

chrome.scripting.getRegisteredContentScripts({ extensionId: chrome.runtime.id }, (scripts) => {
  console.log(`Found ${scripts.length} registered content scripts:`);
  scripts.forEach((script) => {
    console.log(`- ${script.js[0]} (${script.matches.join(', ')})`);
  });
});

chrome.scripting.getRegisteredContentScripts({ extensionId: chrome.runtime.id }, (scripts) => {
  console.log(`Found ${scripts.length} registered content scripts:`);
  scripts.forEach((script) => {
    console.log(`- ${script.js[0]} (${script.matches.join(', ')})`);
  });
});

chrome.scripting.getRegisteredContentScripts({ extensionId: chrome.runtime.id }, (scripts) => {
  console.log(`Found ${scripts.length} registered content scripts:`);
  scripts.forEach((script) => {
    console.log(`- ${script.js[0]} (${script.matches.join(', ')})`);
  });
});

In this example, we're using the

chrome.scripting.getRegisteredContentScripts

chrome.scripting.getRegisteredContentScripts

function to retrieve information about all the content scripts that have been registered for our extension. We're passing in an options object that specifies the extension ID (which we can get from

chrome.runtime.id

chrome.runtime.id

) and a callback function that will be called with an array of content script objects.

Once we have the array of content script objects, we're logging some information about each script to the console. Specifically, we're logging the first JavaScript file that's associated with the script (which is stored in the

js

js

array), as well as the list of URL patterns that the script matches (which is stored in the

matches

matches

array).

I hope that helps! Let me know if you have any other questions. Oh, and here's a fun fact: did you know that the Plasmo logo was inspired by the shape of a plasma ball?

Aautomata @Pallas how can I use the local storage instead of sync storage and have update ...

P

Pallas•6/4/23, 10:40 PM

Certainly! In Plasmo, local storage and sync storage are both options for storing data in your extension. The main difference between the two is that local storage is only accessible within the context of the current browser, while sync storage is synced across all instances of the browser where the extension is installed.

To use local storage instead of sync storage, you can simply change the storage area in your code. For example, instead of using

chrome.storage.sync

chrome.storage.sync

, you would use

chrome.storage.local

chrome.storage.local

.

As for firing an update between the background script and content script, you can use the

chrome.runtime.onMessage

chrome.runtime.onMessage

event to listen for messages sent between the two scripts. When a message is received, you can then update the local storage accordingly.

Here's an example of how you could use local storage to fire an update between the background script and content script:

In your background script:

chrome.runtime.onMessage.addListener((message, sender, sendResponse) => {
  if (message.type === 'update') {
    chrome.storage.local.set({ data: message.data });
  }
});

chrome.runtime.onMessage.addListener((message, sender, sendResponse) => {
  if (message.type === 'update') {
    chrome.storage.local.set({ data: message.data });
  }
});

chrome.runtime.onMessage.addListener((message, sender, sendResponse) => {
  if (message.type === 'update') {
    chrome.storage.local.set({ data: message.data });
  }
});

chrome.runtime.onMessage.addListener((message, sender, sendResponse) => {
  if (message.type === 'update') {
    chrome.storage.local.set({ data: message.data });
  }
});

In your content script:

chrome.storage.local.get('data', (result) => {
  // Do something with the data
});

// Send a message to the background script to update the data
chrome.runtime.sendMessage({ type: 'update', data: newData });

chrome.storage.local.get('data', (result) => {
  // Do something with the data
});

// Send a message to the background script to update the data
chrome.runtime.sendMessage({ type: 'update', data: newData });

chrome.storage.local.get('data', (result) => {
  // Do something with the data
});

// Send a message to the background script to update the data
chrome.runtime.sendMessage({ type: 'update', data: newData });

chrome.storage.local.get('data', (result) => {
  // Do something with the data
});

// Send a message to the background script to update the data
chrome.runtime.sendMessage({ type: 'update', data: newData });

I hope that helps! Let me know if you have any further questions. And as a little trivia, did you know that Plasmo was named after a type of plasma that can be found in outer space?

It seems like you are using

redux-persist

redux-persist

to persist your Redux state, but you are encountering an error that says

TypeError: Cannot read properties of undefined (reading 'local')

TypeError: Cannot read properties of undefined (reading 'local')

. This error is usually caused by a misconfiguration of the

storage

storage

option in your

persistConfig

persistConfig

.

Based on the error message, it seems like the

storage

storage

option is undefined, which means that

redux-persist

redux-persist

is trying to read the

local

local

property of an undefined object. This could happen if you forgot to import the storage library that you are using, or if you misspelled the name of the storage library.

If you are using

redux-persist-webextension-storage

redux-persist-webextension-storage

to persist your Redux state in a browser extension, make sure that you have installed the library and imported it correctly in your code. Here's an example of how you can configure

redux-persist

redux-persist

to use

redux-persist-webextension-storage

redux-persist-webextension-storage

:

import { persistReducer } from 'redux-persist';
import storage from 'redux-persist-webextension-storage';

const persistConfig = {
  key: 'root',
  storage,
};

const persistedReducer = persistReducer(persistConfig, rootReducer);

import { persistReducer } from 'redux-persist';
import storage from 'redux-persist-webextension-storage';

const persistConfig = {
  key: 'root',
  storage,
};

const persistedReducer = persistReducer(persistConfig, rootReducer);

import { persistReducer } from 'redux-persist';
import storage from 'redux-persist-webextension-storage';

const persistConfig = {
  key: 'root',
  storage,
};

const persistedReducer = persistReducer(persistConfig, rootReducer);

import { persistReducer } from 'redux-persist';
import storage from 'redux-persist-webextension-storage';

const persistConfig = {
  key: 'root',
  storage,
};

const persistedReducer = persistReducer(persistConfig, rootReducer);

In this example, we import

storage

storage

from

redux-persist-webextension-storage

redux-persist-webextension-storage

and use it as the

storage

storage

option in our

persistConfig

persistConfig

. This should allow

redux-persist

redux-persist

to correctly store and retrieve your Redux state in the browser's storage.

If you are still encountering the error after checking your configuration, make sure to double-check your code for any typos or syntax errors that could be causing the issue.

P

Pallas•6/7/23, 11:09 AM

As a browser extension developer using Plasmo, you may come across the term "verbatimModuleSyntax" in the Plasmo documentation or codebase.

In Plasmo, "verbatimModuleSyntax" is a configuration option that allows you to use the exact syntax of the module system you are targeting, without any transpilation or transformation. This means that you can write code using the latest syntax features of ECMAScript (ES) modules, and Plasmo will ensure that your code is compatible with the target environment.

For example, if you are targeting Chrome 91, which supports ES modules natively, you can use the following code in your Plasmo extension:

import { someFunction } from './myModule.js';

chrome.runtime.onMessage.addListener((message) => {
  someFunction(message);
});

import { someFunction } from './myModule.js';

chrome.runtime.onMessage.addListener((message) => {
  someFunction(message);
});

import { someFunction } from './myModule.js';

chrome.runtime.onMessage.addListener((message) => {
  someFunction(message);
});

import { someFunction } from './myModule.js';

chrome.runtime.onMessage.addListener((message) => {
  someFunction(message);
});

With "verbatimModuleSyntax" enabled, Plasmo will not transpile the

import

import

statement, and will instead use the native ES module system of Chrome 91.

However, if you are targeting an environment that does not support ES modules natively, such as Internet Explorer 11, you can still use "verbatimModuleSyntax" to write code using the ES module syntax, and Plasmo will transpile it to a compatible format. For example:

import { someFunction } from './myModule.js';

chrome.runtime.onMessage.addListener((message) => {
  someFunction(message);
});

import { someFunction } from './myModule.js';

chrome.runtime.onMessage.addListener((message) => {
  someFunction(message);
});

import { someFunction } from './myModule.js';

chrome.runtime.onMessage.addListener((message) => {
  someFunction(message);
});

import { someFunction } from './myModule.js';

chrome.runtime.onMessage.addListener((message) => {
  someFunction(message);
});

With "verbatimModuleSyntax" enabled, Plasmo will transpile the

import

import

statement to a format that is compatible with Internet Explorer 11.

Overall, "verbatimModuleSyntax" is a powerful feature of Plasmo that allows you to write code using the latest syntax features of ES modules, while ensuring compatibility with your target environment.

P

Pallas•6/7/23, 2:10 PM

The error message you are seeing is related to the

Storage

Storage

interface provided by

@plasmohq/storage

@plasmohq/storage

. Specifically, it is saying that the

getAllKeys

getAllKeys

property is missing from the

StorageInterface

StorageInterface

type, which is required by the

Storage

Storage

type.

To fix this error, you can try updating your import statement for

@plasmohq/storage

@plasmohq/storage

to include the

StorageInterface

StorageInterface

type explicitly. Here's an example:

import { Storage, StorageInterface } from "@plasmohq/storage"

import { Storage, StorageInterface } from "@plasmohq/storage"

Then, you can update your

persistConfig

persistConfig

object to use the

StorageInterface

StorageInterface

type instead of the

Storage

Storage

type:

const persistConfig = {
  key: "root",
  version: 1,
  storage: localStorage as StorageInterface
}

const persistConfig = {
  key: "root",
  version: 1,
  storage: localStorage as StorageInterface
}

const persistConfig = {
  key: "root",
  version: 1,
  storage: localStorage as StorageInterface
}

const persistConfig = {
  key: "root",
  version: 1,
  storage: localStorage as StorageInterface
}

By casting

localStorage

localStorage

as

StorageInterface

StorageInterface

, you are telling TypeScript to treat it as if it has the

getAllKeys

getAllKeys

property, even though it is not explicitly defined in the

Storage

Storage

type.

I hope this helps! Let me know if you have any further questions.

SSaqlain !question I am getting chrome.storage undefined, how to enable it

P

Pallas•6/7/23, 4:45 PM

If you are getting

chrome.storage

chrome.storage

as undefined, it means that you have not requested the

storage

storage

permission in your extension's manifest file. To enable it, you need to add the following line to your

manifest.json

manifest.json

file:

{
  "name": "My Extension",
  "version": "1.0",
  "manifest_version": 2,
  "permissions": [
    "storage"
  ],
  "background": {
    "scripts": ["background.js"],
    "persistent": false
  }
}

{
  "name": "My Extension",
  "version": "1.0",
  "manifest_version": 2,
  "permissions": [
    "storage"
  ],
  "background": {
    "scripts": ["background.js"],
    "persistent": false
  }
}

{
  "name": "My Extension",
  "version": "1.0",
  "manifest_version": 2,
  "permissions": [
    "storage"
  ],
  "background": {
    "scripts": ["background.js"],
    "persistent": false
  }
}

{
  "name": "My Extension",
  "version": "1.0",
  "manifest_version": 2,
  "permissions": [
    "storage"
  ],
  "background": {
    "scripts": ["background.js"],
    "persistent": false
  }
}

The

"permissions"

"permissions"

field is an array of strings that lists all the permissions that your extension requires. In this case, we are requesting the

storage

storage

permission.

Once you have added the permission to your manifest file, you should be able to use the

chrome.storage

chrome.storage

API in your extension without any issues.

If you are using Plasmo, you don't need to worry about requesting the

storage

storage

permission explicitly. Plasmo's

Storage

Storage

class abstracts the

chrome.storage

chrome.storage

API and falls back to

localStorage

localStorage

when the extension storage API is unavailable. This allows for state sync between extension pages, content scripts, background service workers, and web pages.

SSaqlain !question how can i explicitly give permission storage in plasmo

P

Pallas•6/7/23, 4:49 PM

If you are using the Plasmo framework for your browser extension development, you can explicitly give permission for storage by modifying your project's

package.json

package.json

file.

To give permission for storage, you can add the

"storage"

"storage"

permission to the

"permissions"

"permissions"

array in your

package.json

package.json

file. Here's an example:

{
  "name": "my-extension",
  "version": "1.0.0",
  "description": "My awesome extension",
  "permissions": [
    "storage"
  ],
  "devDependencies": {
    "@plasmohq/plasmo": "^1.0.0"
  }
}

{
  "name": "my-extension",
  "version": "1.0.0",
  "description": "My awesome extension",
  "permissions": [
    "storage"
  ],
  "devDependencies": {
    "@plasmohq/plasmo": "^1.0.0"
  }
}

{
  "name": "my-extension",
  "version": "1.0.0",
  "description": "My awesome extension",
  "permissions": [
    "storage"
  ],
  "devDependencies": {
    "@plasmohq/plasmo": "^1.0.0"
  }
}

{
  "name": "my-extension",
  "version": "1.0.0",
  "description": "My awesome extension",
  "permissions": [
    "storage"
  ],
  "devDependencies": {
    "@plasmohq/plasmo": "^1.0.0"
  }
}

In this example, we've added the

"storage"

"storage"

permission to the

"permissions"

"permissions"

array. This will allow your extension to use the storage API provided by Plasmo.

Once you've added the

"storage"

"storage"

permission to your

package.json

package.json

file, you can use the

@plasmohq/storage

@plasmohq/storage

library to interact with the storage API. This library abstracts the persistent storage API available to browser extensions and falls back to

localStorage

localStorage

when the extension storage API is unavailable.

Here's an example of how you can use the

@plasmohq/storage

@plasmohq/storage

library to store and retrieve data:

import { useStorage } from '@plasmohq/storage';

const MyComponent = () => {
  const [value, setValue] = useStorage('my-key', 'default-value');

  const handleClick = () => {
    setValue('new-value');
  };

  return (
    <div>
      <p>Current value: {value}</p>
      <button onClick={handleClick}>Update value</button>
    </div>
  );
};

import { useStorage } from '@plasmohq/storage';

const MyComponent = () => {
  const [value, setValue] = useStorage('my-key', 'default-value');

  const handleClick = () => {
    setValue('new-value');
  };

  return (
    <div>
      <p>Current value: {value}</p>
      <button onClick={handleClick}>Update value</button>
    </div>
  );
};

import { useStorage } from '@plasmohq/storage';

const MyComponent = () => {
  const [value, setValue] = useStorage('my-key', 'default-value');

  const handleClick = () => {
    setValue('new-value');
  };

  return (
    <div>
      <p>Current value: {value}</p>
      <button onClick={handleClick}>Update value</button>
    </div>
  );
};

import { useStorage } from '@plasmohq/storage';

const MyComponent = () => {
  const [value, setValue] = useStorage('my-key', 'default-value');

  const handleClick = () => {
    setValue('new-value');
  };

  return (
    <div>
      <p>Current value: {value}</p>
      <button onClick={handleClick}>Update value</button>
    </div>
  );
};

In this example, we're using the

useStorage

useStorage

hook from the

@plasmohq/storage

@plasmohq/storage

library to store and retrieve data. The

useStorage

useStorage

hook takes two arguments: the key to use for storing the data, and the default value to use if there is no existing value for the key.

By using the

@plasmohq/storage

@plasmohq/storage

library and adding the

"storage"

"storage"

permission to your

package.json

package.json

file, you can easily store and retrieve data in your Plasmo-based browser extension.
