Add Laravel .env variable to Vue component

Pulled from the official docs @ https://laravel.com/docs/5.6/mix#environment-variables

Environment Variables

You may inject environment variables into Mix by prefixing a key in your .env file with MIX_:

MIX_SENTRY_DSN_PUBLIC=http://example.com

After the variable has been defined in your .env file, you may access via the process.env object. If the value changes while you are running a watch task, you will need to restart the task:

process.env.MIX_SENTRY_DSN_PUBLIC

---

The most important thing to remember is that you have to use Laravel Mix for this to work. Mix is what is injecting the environment variable.

 process.env.MIX_VAR /  process.env.MIX_STRIPE_KEY

It's will work without any settings. Just run this command

npm run prod

in windows :

thats worked for me without any require in webpack.mix

... just add a new variable in env file with this prefix : MIX_

MIX_API_URL=http://laravel:8000

but need to restart php artisan serve and also restart npm run watch....

  let api_url = process.env.MIX_API_URL;
  console.log("my env variable:");
  console.log(api_url);

in linux or docker:

i didnt use them yet

You must build your JS for the env variables to be replaced. You can do this with npm or yarn
