This library allows the user to read different .env files based on the environment variable (NODE_ENV).

This project was inspired from dotenv.

npm install dot2env

Create a .env file in the root of your project:

USERNAME="jex"
password="secret"

As early as possible in your application, import and configure dot2env:

import "@jexsrs/dot2env";

console.log(process.env.USERNAME);
console.log(process.env.PASSWORD);

The supported environments are:

• production, prod
• staging, stage
• testing, test
• development, dev

For each environment you will have to create a .env.[environment] file (using the full name).

Now everytime you call your application using an environment, it will automatically import all the variables in that file.

For example, running:

NODE_ENV=production node index.js

will import only the .env.production file.

If the .env.[environment] file is not found, it will always fallback to the .env file.

If you want to override existing environment variables, use the override option.

import {load} from "@jexsrs/dot2env";

load({override: true});

In case you want to add more environments or use custom ones you can define your own mapping:

import {load} from "@jexsrs/dot2env";

load({
    envMap: {
        development: '.env.development',
        testing: '.env.testing',
        staging: '.env.staging',
        production: '.env.production',
        'custom-env': '.env.custom-environment'
    }
});
