Getting issue with Deploying ENV and acceessing it into my project

[amir8]

I have created three worker and I deployed routes successfully. Those three workers are staging, pre-prod and production. I wanted to allow these workers to use there own environment so i added three environment in wrangler.toml file , one for staging , one for pre-prod and for production. see below .toml file.

name = "platform"
main = "src/worker.ts"
account_id = "f2c26572459df7786bb"
compatibility_date = "2023-08-07"

node_compat = true

[vars]
Domain=example.com

[env.staging]
DATABASE_NAME = "planet"
DATABASE_HOST = "aws.connect.psdb.cloud"
DATABASE_USERNAME = "rzjbmize3gwsv5z"
DATABASE_PASSWORD = "pscale_pw_DrDIOQIUozpd7xTH49cvWPm"
APP = "staging"

[env.pre]
DATABASE_NAME = "planet"
DATABASE_HOST = "aws.connect.psdb.cloud"
DATABASE_USERNAME = "rzjbmize3gwsv5z"
DATABASE_PASSWORD = "pscale_pw_DrDIOQIUozpd7xTH49cvWPm"
APP = "preprod"

[env.production]
DATABASE_NAME = "planet"
DATABASE_HOST = "aws.connect.psdb.cloud"
DATABASE_USERNAME = "rzjbmize3gwsv5z"
DATABASE_PASSWORD = "pscale_pw_DrDIOQIUozpd7xTH49cvWPm"
TEST_URL = "https://localhost:61657"
APP = "production"

i am not able to deploy it staging worker with below command wrangler deploy --env staging

also i am not able to access domain name inside my worker.ts file. how can i access variable inside the function.

below is the the worker.ts file.

import { Router } from 'itty-router';

const router = Router();

// Define your routes
router.get('/', () => new Response('Hello, world!'));

router.get('/ping', (request,env) => {
	console.log(env.Domain);
	
	const url = request.url;
	const responseBody = { status: 'ok', env: url.includes('staging') ? 'staging' : url.includes('pre') ? 'pre' : 'production' };
	const responseInit = {
		status: 200,
		headers: { 'Content-Type': 'application/json' },
	};
	return new Response(JSON.stringify(responseBody), responseInit);
});

// Catch-all route
router.all('*', () => new Response('404 - Not Found', { status: 404 }));
// Handle incoming requests using the router
addEventListener('fetch', async (event: FetchEvent) => {
	event.respondWith(handleRequest(event));
});

async function handleRequest(event: FetchEvent): Promise<Response> {
	const request = event.request;
	const context = { request };
	return router.handle(event.request, context);
}

I need to access variable inside my routes function also ineed to deploy env variable for staging to staging with above command.

What version of itty-router are you using @amir8?

If you are using v4 I suggest checking out the documentation as much has changed.

[amir8]

@anon9246926 I am using “itty-router”: “^4.0.22”,

[anon9246926]

Then you’ll need to modify the code you have to work correctly. There are good examples in the documentation to work from.

[amir8]

I am Trying with that example but still not able to access it

import { Router, error, json } from 'itty-router';

const router = Router();

// Define your routes
router
  .get('/', (request, environment, context) => {
    // we can access anything here that was passed to `router.handle`.

	return new Response(JSON.stringify(environment.DATABASE_NAME));
  })

// Catch-all route
router.all('*', () => new Response('404 - Not Found', { status: 404 }));

// Handle incoming requests using the router
interface Env {

}
export default {
	fetch: (req:Request, env:Env, ctx:ExecutionContext) => router
								.handle(req, env, ctx)
								.then(json)
								.catch(error)
  }

As mentioned in this documentation you need to add a vars key under [env.ENVNAME] e.g.

[env.staging]
vars = { ENVIRONMENT = "staging" }

The other option (which I can’t see mentioned anywhere in the documentation, though it possibly is) to go

[env.staging]
  [env.staging.vars]
    DATABASE_NAME = "planet"
    DATABASE_HOST = "aws.connect.psdb.cloud"
    DATABASE_USERNAME = "rzjbmize3gwsv5z"
    DATABASE_PASSWORD = "pscale_pw_DrDIOQIUozpd7xTH49cvWPm"
    APP = "staging"

Note that Domain is undefined in both instances as it isn’t part of the environment.

This is not working

[env.staging]
  [env.staging.vars]
    DATABASE_NAME = "planet"
    DATABASE_HOST = "aws.connect.psdb.cloud"
    DATABASE_USERNAME = "rzjbmize3gwsv5z"
    DATABASE_PASSWORD = "pscale_pw_DrDIOQIUozpd7xTH49cvWPm"
    APP = "staging"

But when i write like below i am able to access env variables

[vars]
 DATABASE_NAME = "planet"
    DATABASE_HOST = "aws.connect.psdb.cloud"
    DATABASE_USERNAME = "rzjbmize3gwsv5z"
    DATABASE_PASSWORD = "pscale_pw_DrDIOQIUozpd7xTH49cvWPm"
    APP = "staging"

Tanks for you Support. But still i am facing issue is that how can deploy staging env to staging if i am not able to access it if write like below

[env.staging]
vars={ENVIRONMENT = "staging"}
Because this allows me write only one variable if i wrire more i am not able to acess those varibles again.

@amir8

This is not working

It works for me when tested locally running wrangler dev --env staging

@amir8

But still i am facing issue is that how can deploy staging env to staging if i am not able to access it if write like below

This also works when written like

[env.staging]
  vars = { DATABASE_NAME = "planet", DATABASE_HOST = "aws.connect.psdb.cloud", DATABASE_USERNAME = "rzjbmize3gwsv5z", DATABASE_PASSWORD = "pscale_pw_DrDIOQIUozpd7xTH49cvWPm", APP = "staging" }

Note you need to write it on a single line.

Edit: The above also works when deployed using wrangler deploy --env staging
