With .env files, it was easy to inject variables in webpacker js packs. Since 5.2, you can use the encrypted secrets, but is there a way to read (decrypt) them in inject some of them on webpacker build time?

You can read from credentials and pass that value to Webpacker.

  1. Create a config/initializers/webpacker.rb file.

  2. Pass it to the Webpacker::Compiler through file above.

    Webpacker::Compiler.env['VALUE'] = Rails.application.credentials.dig(:value)

  3. Read it as console.log(process.env.VALUE).

  4. If you want to try it on development, you need to add these to the bin/webpack-dev-server:

    require_relative '../config/application'
Rails.application.initialize!
