worker environment variables, please help :)

I am pretty new to Cloudflare workers, I am using it for a personal app. my problem is that when i try to access my environment variables inside of the worker i simply get an error. now im pretty sure that its because im using javascript and not typescript, can anyone help me? thanks! (the doc i read that sadly didnt work) https://developers.cloudflare.com/workers/configuration/environment-variables/

how are you accessing the environment variables? are you doing so via the Env object passed into the worker at runtime?

Do you have some sample code we could take a look at? Might help in figuring out what’s wrong

okay, please dont judge the code i made, it may look stupid in your eyes...

export default {
  async fetch(request, env, context) {
    const {
      ENV_SERVICE_ACCOUNT_EMAIL: SERVICE_ACCOUNT_EMAIL,
      ENV_PRIVATE_KEY_PEM: PRIVATE_KEY_PEM,
      ENV_TOKEN_URL: TOKEN_URL,
      ENV_SHEET_ID: SHEET_ID,
      ENV_RANGE: RANGE,
      ENV_SERVER_HASH: SERVER_HASH
    } = env;

  async fetch(request, env, context) {
    const {
      ENV_SERVICE_ACCOUNT_EMAIL: SERVICE_ACCOUNT_EMAIL,

      ENV_TOKEN_URL: TOKEN_URL,
      ENV_SHEET_ID: SHEET_ID,
      ENV_RANGE: RANGE,
      ENV_SERVER_HASH: SERVER_HASH
    } = env;

that was just a small snippet of my code where i try to define the variables within my worker.js

see https://developers.cloudflare.com/workers/configuration/environment-variables/#add-environment-variables-via-the-dashboard on how to set environment variables via the dashboard. Are all your environment variables visible via the worker settings menu?

Are you running the worker locally or deployed?

stormcph•9mo ago

deployed i tried doing it like this, also note that the "variable" is just a placeholder for the actual names of the variable

const VARIABLE = self['VARIABLE'];

const VARIABLE = self['VARIABLE'];

also there are multiple but for this example we only ned to display one
