A .env or dotenv file is a configuration file of an application. It loads environment variables from a .env file into process.env. In this article, I’m going to show how to set & use it in Nuxt.js.

Install dotenv Package

To use .env files in Nuxt, we need to install @nuxtjs/dotenv modules. Let’s do this:

npm install @nuxtjs/dotenv

Then register the dotenv module to nuxt.config.js file like:

buildModules: [
    '@nuxtjs/dotenv'
],

Set & Use Variable

Create a .env file at the root of your project directory. Then let’s create a simple variable:

TEST_VARIABLE=Hello MyNotePaper

Now we’re able to get the variable in our app like:

console.log(process.env.TEST_VARIABLE);

Amazing, it works! ?

Recommendation

In Nuxt v2.13, they introduced runtime config feature. Please try to use environment variables like new method. Have a look at their blog post.
