Simple react-native environment variables

react-native-simple-env

Simple environment variables for react-native

Goals

• Read environment variables from .env* files.
• Specify which env file to read from (i.e. .env.staging).
• Read environment variables exorted in the shell process.
• Tests!

Installation

// yarn
$ yarn add react-native-simple-env

// npm
$ npm i react-native-simple-env

Usage

RNSE imports any variables defined in the .env file, in addition to any system environment variables exported in the shell process that begin with REACT_NATIVE_.

// .env

REACT_NATIVE_API_URL=https://swapi.co/api/
SUCCESS_MESSAGE='It still works'

import {env} from "react-native-simple-env";

fetch(env.API_URL)
.then(() => console.log(env.SUCCESS_MESSAGE);

To specify which .env file to use, set the RN_ENV variable to the name of the file you want to use when starting the bundler.

$ RN_ENV=.env.staging react-native start`

Precendence

1. Variables exported in the terminal process running the metro bundler.
2. Variables defined in .env* file.
