[Feature request] Document support for environment variables

Extensions
2

For remix server, remix doesn’t support multiple environment variables, only support .env file for local development to override variables.

so you need define environment variables in each servers.

  • local development : .env
  • other environment : set variables to each server

on the other hand, app extension has a solution to load environment variables.

  • npm run shopify app deploy -- -c sandbox uses shopify.app.sandbox.toml and .env.sandbox
  • npm run shopify app deploy -- -c production uses shopify.app.production.toml and .env.production

Hope this helps :slight_smile:
