How to access env variables?

I set one using wrangler and now I can't access it? I couldn't even find a way to access it in the docs help me.

You need to pass the context in when using env() https://hono.dev/helpers/adapter#env

Hello, I’m Allie!•3mo ago

You are extracting GEMINI_AI, but then trying to use GEMINI_API

avglinuxguy•3mo ago

I corrected it Is there a way to use it wihout using (c)? The thread it corrected, read one it GEMINI_API

Hello, I’m Allie!•3mo ago

No, you are supposed to use c Environment Variables are not accessible in a global context

avglinuxguy•3mo ago

import { Hono } from 'hono';
import { env } from 'hono/adapter';

const app = new Hono();

app.get('/', (c) => {

  const {GEMINI_AI} = env(c)
  console.log("my key:" + GEMINI_API)
  return c.json({
      message: 'Live!',
      env: GEMINI_API
  })
})

export default app;

import { Hono } from 'hono';
import { env } from 'hono/adapter';

const app = new Hono();

app.get('/', (c) => {

  const {GEMINI_AI} = env(c)
  console.log("my key:" + GEMINI_API)
  return c.json({
      message: 'Live!',
      env: GEMINI_API
  })
})

export default app;

Ok, so in this code I want to access the env outsite the get? so ho do I do that?

Hello, I’m Allie!•3mo ago

You don't. Environment variables are only defined within the get Or whatever other handler functions you define

avglinuxguy•3mo ago

Ok, so I can do this right? let output = await run(c); ?? Like I need the value of env in my run()

Hello, I’m Allie!•3mo ago

Yes, you can do that

import { Hono } from 'hono'
import { env, getRuntimeKey } from 'hono/adapter'
import { GoogleGenerativeAI } from '@google/generative-ai';

const app = new Hono();

async function run(content: any) {
  // For text-only input, use the gemini-pro model
  const {GEMINI_API} = env(content)
  const genAI = new GoogleGenerativeAI(GEMINI_API);
  const model = genAI.getGenerativeModel({ model: "gemini-pro"});

  const prompt = "Write a story about a magic backpack."

  const result = await model.generateContent(prompt);
  const response = await result.response;
  const text = response.text();
  return text
}

app.get('/', async (c) => {

  // const {GEMINI_API} = env(c)

  console.log(ans)
  console.log("my key:")
  return c.json({

Am I doing it right, it's working, but sometimes give internal server error.

Hello, I’m Allie!•3mo ago

Looks right to me. What does the error show?

avglinuxguy•3mo ago

Just internal server error is there a console on on Cloudflare, let me check Now, After the second deployment the errors vanished now no more errors.

Hello, I’m Allie!•3mo ago

Does it work locally?

avglinuxguy•3mo ago

Yes, it working fine now. Just a little slow I will enable streaming now, so it gives words one by one. Let's see how can I do that

I didn't had cors in it, so was working with my IP only. Couldn't open the site from anyohter place

import { Hono } from 'hono'
import { cors } from 'hono/cors'
import { env, getRuntimeKey } from 'hono/adapter'
import { GoogleGenerativeAI } from '@google/generative-ai';

const app = new Hono();

app.use('/*', cors())

async function run(content: any) {
  // For text-only input, use the gemini-pro model
  const {GEMINI_API} = env(content)
  const genAI = new GoogleGenerativeAI(GEMINI_API);
  const model = genAI.getGenerativeModel({ model: "gemini-pro"});

  const prompt = "Write a line."

  const result = await model.generateContent(prompt);
  const response = await result.response;
  const text = response.text();
  return text
}

app.get('/', async (c) => {

  const ans = await run(c);
  return c.json({
      message: 'Live!',
      Quote: ans
  })
})

app.get('/v1', async (c) => {

  // const ans = await run(c);
  return c.text("ans")
})


export default app;

import { Hono } from 'hono'
import { cors } from 'hono/cors'
import { env, getRuntimeKey } from 'hono/adapter'
import { GoogleGenerativeAI } from '@google/generative-ai';

const app = new Hono();

app.use('/*', cors())

async function run(content: any) {
  // For text-only input, use the gemini-pro model
  const {GEMINI_API} = env(content)
  const genAI = new GoogleGenerativeAI(GEMINI_API);
  const model = genAI.getGenerativeModel({ model: "gemini-pro"});

  const prompt = "Write a line."

  const result = await model.generateContent(prompt);
  const response = await result.response;
  const text = response.text();
  return text
}

app.get('/', async (c) => {

  const ans = await run(c);
  return c.json({
      message: 'Live!',
      Quote: ans
  })
})

app.get('/v1', async (c) => {

  // const ans = await run(c);
  return c.text("ans")
})


export default app;

I have this code, and I can't access it outside my home network. I don't know why /v1 route is working but not the / route ANS: it's not wokers it GEMINI API: giving this output.

"Error: [GoogleGenerativeAI Error]: Error fetching from https://generativelanguage.googleapis.com/v1/models/gemini-pro:generateContent: [400 Bad Request] User location is not supported for the API use."

Hello, I’m Allie!•3mo ago

That sounds like an issue from Google’s end They might have locked their APIs down to certain locations by IP

avglinuxguy•3mo ago

It works with my HOME network but not with the mobile LOL What a pain. Need to find some other free LLM api Nope, finally I found the issue was with the way CloudFlare handled the reqeust, since Google is geo-blocking in some countries, When I was using fiber internet it worked, but when I switched to mobile internet I don't know how cloudflare did it's routing, but it might have went to some geo-blocked country like EU etc. But the logs always showed some IP from India. Using the VPN worked.
