failed to use Webpacker::Compiler.env

[petitkriket]

Hi,
Having an issue with webpacker initializer.
As pointed in the env doc I create an initializer to pass Rails application variables to a JS frontend, process.env.FRONTEND_API_KEY ends up empty.

It has already been talked about but left unsolved.

Am I doing something wrong or missing something ?

# in config/initializersd/webpacker.rb
Webpacker::Compiler.env['FRONTEND_API_KEY'] = Rails.application.credentials.dig(Rails.env.to_sym, :some_api_key)
# Webpacker.compiler.env returns a hash with the data

// in  application.js
console.log(process.env.FRONTEND_API_KEY)
// returns undefined

I'm having the same issue as @nozpheratu - setting variables with Webpacker::Compiler.env doesn't seem to make it into the actual javascript environment. Anyone have a suggestion? Did this break somewhere?

Ok digged google and found an article where @takeyuweb explain why it does not work on dev environment and how to circumvent the issue

# bin/webpack-dev-server
require_relative '../config/application'
Rails.application.initialize!

It works on production without doing anything and just fixes the development env issue

Should it be addressed ?

adding the following

# bin/webpack-dev-server
require_relative '../config/environment'

might serve as a shortcut for:

the following link should work for the env doc shared in the OP:
