How do i connect APIs to Open SaaS ?

kapa.ai•8/19/24, 1:22 PM

Hi @priv_.1511. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:

kapa.ai•8/19/24, 1:23 PM

----------------------
To connect APIs to Open SaaS, you would typically create an API route in your Wasp application. This is done by defining the endpoint in your main.wasp file and implementing the corresponding function in TypeScript.

For example, if you're trying to implement an authentication system, you might create an endpoint like /api/generate-jwt/api/generate-jwt and implement a generateJwtgenerateJwt function. This function would handle the logic of generating a JWT token when a user logs in.

Here's a general example of how you might set up the API and function:

// In your main.wasp file
apiRoute '/api/generate-jwt' { ... }

// In your TypeScript file
export function generateJwt() {
  // Your logic here
}

// In your main.wasp file
apiRoute '/api/generate-jwt' { ... }

// In your TypeScript file
export function generateJwt() {
  // Your logic here
}

When you make changes to your API routes or functions, make sure to restart the Wasp server for the changes to take effect.

If you're trying to call a third-party API from your Wasp application, you might need to create an action that makes the API request. This action would be defined in your main.wasp file and implemented in TypeScript. You would then call this action from your client-side code.

Please note that if you're making requests to a third-party API from the client side, you might run into CORS issues. To avoid this, you can make the API request from the server side instead.

For more detailed instructions on how to work with APIs in Wasp, you can refer to the Wasp documentation (https://wasp-lang.dev/docs/advanced/apis).

hey

miho•8/19/24, 2:10 PM

I'd recommend going through the Wasp tutorial to get familiar with Wasp: https://wasp-lang.dev/docs/tutorial/create

You can write any Node.js code in the Wasp queries, actions and custom APIs

You'll need to have the latest version of Wasp installed locally to follow this tutorial. If you haven't installed it yet, check out the QuickStart guide!

p1511OP•8/19/24, 2:39 PM

Thanks @miho ! Im new to coding. Want to build a SaaS using Open SaaS Wasp template. May i ask, aside from the ready-made features by Open SaaS Wasp like auth,payments and so on, Lets say im building a Auto generated caption software, basically the rest of the code (except given by Wasp) i need to write on my own? Sorry if my question sounds funny but i really wanna know.

miho•8/19/24, 3:20 PM

Yep, Wasp is a development framework that help you build things faster, but it is still a very code framework. So you need to know React for the frontend and Node.js for the backend to successfully use it

Or be very good in asking ChatGPT with the things you don't know

The error message you're seeing usually indicates that the waspwasp command is not available in your system's PATH. This could be because Wasp is not installed, or because the location where it's installed is not included in the PATH.

Here's how you can resolve this:

First, check if Wasp is installed by running wasp versionwasp version in your terminal. If Wasp is installed, this command should return the installed version of Wasp.
If Wasp is not installed, you can install it by following the instructions in the Wasp documentation (https://wasp-lang.dev/docs/getting-started/installation).
If Wasp is installed but the waspwasp command is not recognized, it's likely that the location where Wasp is installed is not included in your system's PATH. You can add it to the PATH by following the instructions specific to your operating system.

Once you've ensured that Wasp is installed and the waspwasp command is available, you should be able to run

wasp db migrate-dev

wasp db migrate-dev

without any issues. This command is used to synchronize the development database with the current state of the schema (entities). If there are any changes in the schema, it generates a new migration and applies any pending migrations to the database. You can learn more about this command in the Wasp documentation (https://wasp-lang.dev/docs/general/cli#database-commands).

It seems like you're using PowerShell on Windows, which doesn't recognize shsh as a command. The shsh command is used to run shell scripts in Unix-like systems, but it's not available by default on Windows.

To install Wasp on Windows, you should use Windows Subsystem for Linux (WSL). Here are the steps:

Install WSL by following the instructions on the Microsoft documentation (https://learn.microsoft.com/en-us/windows/wsl/install).
Once you've installed WSL and set up a Linux distribution (like Ubuntu), open a new WSL terminal window.
In the WSL terminal, run the following command to install Wasp:

curl -sSL <https://get.wasp-lang.dev/installer.sh> | sh

curl -sSL <https://get.wasp-lang.dev/installer.sh> | sh

This command downloads a script from the Wasp website and runs it in the WSL environment, which should install Wasp successfully.

If you encounter any issues or need further help, feel free to reach out to the Wasp community on Discord (https://discord.gg/rzdnErX).

For more details, you can refer to the Wasp documentation (https://wasp-lang.dev/docs/getting-started/installation) and this guide to using Wasp in a WSL environment (https://wasp-lang.dev/blog/2023/11/21/guide-windows-development-wasp-wsl).

` Starting a PostgreSQL dev database (based on your Wasp config) `: This message indicates that Wasp is starting a PostgreSQL database based on the configuration specified in your Wasp project.
`pg_ctl -D /var/lib/postgresql/data -l logfile start`: This is a command that can be used to start the PostgreSQL server manually. However, in this context, it's just an informational message and you don't need to run this command yourself.
`LOG: starting PostgreSQL 16.2 (Debian 16.2-1.pgdg120+2) on x86_64-pc-linux-gnu, compiled by gcc (Debian 12.2.0-14) 12.2.0, 64-bit`: This is a log message from PostgreSQL indicating that it's starting up.
`LOG: database system is ready to accept connections`: This message indicates that the PostgreSQL server has started successfully and is ready to accept connections.
`CREATE DATABASE`: This indicates that a new database is being created.
`PostgreSQL init process complete; ready for start up.`: This message indicates that the initialization process for the PostgreSQL server has completed and the server is ready to start up.
`LOG: invalid length of startup packet`: This is an error message from PostgreSQL. It usually indicates that a client tried to connect to the server but sent a malformed packet. This could be due to a network issue or a problem with the client.

@kapa.ai why my local host is not 3000 but 5432?

kapa.ai•8/20/24, 7:20 AM

Let me check the knowledge base for you. One moment! :books:

kapa.ai•8/20/24, 7:20 AM

----------------------
The port number you're seeing (5432) is the default port for PostgreSQL, which is the database system used by Wasp. When you run

wasp start db

wasp start db

, it starts a PostgreSQL database on port 5432.

On the other hand, port 3000 is the default port for the development server when you run

wasp start

wasp start

. This command starts your Wasp application, and you can access it in your web browser at <http://localhost:3000<http://localhost:3000.>

So, in a typical Wasp project:

The database runs on localhost:5432localhost:5432
The application runs on localhost:3000localhost:3000

If you're seeing a different port number when you try to access your application, it could be due to a configuration issue or because port 3000 is already in use. You can check if this is the case by running lsof -i tcp:3000lsof -i tcp:3000 in your terminal to see if any processes are using port 3000.

If you want to change the port your application runs on, you can do so by modifying the

start

start

script in your

package.json

package.json

file. However, this is generally not recommended unless you have a specific reason to do so.

For more information, you can refer to the Wasp documentation (https://wasp-lang.dev/docs/getting-started/installation) and the Github issues related to port configuration (https://github.com/wasp-lang/wasp/issues/1049) in Wasp.

@kapa.ai Wasp can't run PostgreSQL dev database for you since port 5432 is already in use.

kapa.ai•8/20/24, 7:27 AM

Let me check the knowledge base for you. One moment! :books:

kapa.ai•8/20/24, 7:27 AM

----------------------
The error message you're seeing indicates that the port 5432, which is the default port for PostgreSQL, is already in use on your system. This can happen if you have another instance of PostgreSQL or another service running on the same port.

Here are a few steps you can take to resolve this issue:

Find the process using port 5432: You can use tools like lsoflsof or netstatnetstat on Unix-based systems, or Get-ProcessGet-Process in PowerShell on Windows, to find out which process is using port 5432.
Stop the process: Once you've identified the process, you can stop it to free up the port. Be careful to ensure that the process isn't something critical to your system or another application.
Restart the Wasp database: After freeing up port 5432, you can try running
```
wasp start db
```
```
wasp start db
```
again.

If you're still having trouble, it might be helpful to ask for help on the Wasp Discord server (🙋questionsCant start database docker is not working on wsl properly).
