Using Environment Variables with Vue.js

If you use vue cli with the Webpack template (default config), you can create and add your environment variables to a .env file.

The variables will automatically be accessible under process.env.variableName in your project. Loaded variables are also available to all vue-cli-service commands, plugins and dependencies.

You have a few options, this is from the Environment Variables and Modes documentation:

.env                # loaded in all cases.env.local          # loaded in all cases, ignored by git.env.[mode]         # only loaded in specified mode.env.[mode].local   # only loaded in specified mode, ignored by git

Your .env file should look like this:

VUE_APP_MY_ENV_VARIABLE=valueVUE_APP_ANOTHER_VARIABLE=value

It is my understanding that all you need to do is create the .env file and add your variables then you're ready to go! :)

As noted in comment below:If you are using Vue cli 3, only variables that start with VUE_APP_ will be loaded.

Don't forget to restart serve if it is currently running.

If you are using Vue cli 3, only variables that start with VUE_APP_ will be loaded.

In the root create a .env file with:

VUE_APP_ENV_VARIABLE=value

And, if it's running, you need to restart serve so that the new env vars can be loaded.

With this, you will be able to use process.env.VUE_APP_ENV_VARIABLE in your project (.js and .vue files).

Update

According to @ali6p, with Vue Cli 3, isn't necessary to install dotenv dependency.

1. Create two files in root folder (near by package.json) .env and .env.production
2. Add variables to theese files with prefix VUE_APP_ eg: VUE_APP_WHATEVERYOUWANT
3. serve uses .env and build uses .env.production
4. In your components (vue or js), use process.env.VUE_APP_WHATEVERYOUWANT to call value
5. Don't forget to restart serve if it is currently running
6. Clear browser cache

Be sure you are using vue-cli version 3 or above
