This babel plugin lets you inject your environment variables into your react-native environment using dotenv for multiple environments.
.babelrc
Basic setup:
{
"plugins": [
["module:react-native-dotenv"]
]
}
If the defaults do not cut it for your project, this outlines the available options for your Babel configuration and their respective default values, but you do not need to add them if you are using the default settings.
{
"plugins": [
["module:react-native-dotenv", {
"moduleName": "@env",
"path": ".env",
"blacklist": null,
"whitelist": null,
"safe": false,
"allowUndefined": true
}]
]
}
Note: for safe mode, it’s highly recommended to set allowUndefined
to false
.
.env
API_URL=https://api.example.org
API_TOKEN=abc123
In users.js
import {API_URL, API_TOKEN} from "@env"
fetch(`${API_URL}/users`, {
headers: {
'Authorization': `Bearer ${API_TOKEN}`
}
})
It is possible to limit the scope of env variables that will be imported by specifying a whitelist
and/or a blacklist
as an array of strings.
{
"plugins": [
["module:react-native-dotenv", {
"blacklist": [
"GITHUB_TOKEN"
]
}]
]
}
{
"plugins": [
["module:react-native-dotenv", {
"whitelist": [
"API_URL",
"API_TOKEN"
]
}]
]
}
Enable safe mode to only allow environment variables defined in the .env
file. This will completely ignore everything that is already defined in the environment.
The .env
file has to exist.
{
"plugins": [
["module:react-native-dotenv", {
"safe": true
}]
]
}
Allow importing undefined variables, their value will be undefined
.
{
"plugins": [
["module:react-native-dotenv", {
"allowUndefined": true
}]
]
}
import {UNDEFINED_VAR} from '@env'
console.log(UNDEFINED_VAR === undefined) // true
When set to false
, an error will be thrown. This is no longer default behavior.
This package now supports environment specific variables. This means you may now import environment variables from multiple files, i.e. .env
, .env.development
, .env.production
, and .env.test
.
Note: it is not recommended that you commit any sensitive information in .env
file to code in case your git repo is exposed. The best practice is to put a .env.template
or .env.development.template
that contains dummy values so other developers know what to configure. Then add your .env
and .env.development
to .gitignore
. You can also keep sensitive keys in a separate .env.local
(and respective .env.local.template
) in .gitignore
and you can use your other .env
files for non-sensitive config.
The base set of variables will be .env
and the environment-specific variables will overwrite them.
The variables will automatically be pulled from the appropriate environment and development
is the default. The choice of environment is based on your Babel environment first and if that value is not set, your NPM environment, which should actually be the same, but this makes it more robust.
In general, Release is production
and Debug is development
.
One thing that we’ve noticed is that metro overwrites the test environment variable even if you specify a config so we’ve added a way to fix this. Make sure to specify the config value as indicated in the wiki and make custom configs for alternative builds. However, if you still need this, such as for a staging / test environment, you can add the APP_ENV environment variable in the CLI. For example:
// package.json
{
"scripts": {
"start:staging": "APP_ENV=staging npx react-native start",
}
}
The above example would use the .env.staging
file. The standard word is test
, but go nuts.
npm install @types/react-native-dotenv
Set the moduleName
in your Babel config as react-native-dotenv
.
{
"plugins": [
["module:react-native-dotenv", {
"moduleName": "react-native-dotenv"
}]
]
}
Import your variables from react-native-dotenv
:
import {API_URL} from 'react-native-dotenv'
console.log(API_URL)
types
folder in your project*.d.ts
file, say, env.d.ts
declare module '@env' {
export const API_BASE: string;
}
Add all of your .env variables inside this module.
typeRoots
field in your tsconfig.json
file:{
...
"typeRoots": ["./src/types"],
...
}
When using with babel-loader
with caching enabled you will run into issues where environment changes won’t be picked up. This is due to the fact that babel-loader
computes a cacheIdentifier
that does not take your environment into account.
You can easily clear the cache:
rm -rf node_modules/.cache/babel-loader/*
or
yarn start --reset-cache
or
expo r -c
Maybe a solution for updating package.json scripts:
"cc": "rimraf node_modules/.cache/babel-loader/*,", "android": "npm run cc && react-native run-android", "ios": "npm run cc && react-native run-ios",
Or you can override the default cacheIdentifier
to include some of your environment variables.
The tests that use require('@env')
are also not passing.

If you are undertaking a mobile app development for your start-up or enterprise, you are likely wondering whether to use React Native. As a popular development framework, React Native helps you to develop near-native mobile apps. However, you are probably also wondering how close you can get to a native app by using React Native. How native is React Native?
In the article, we discuss the similarities between native mobile development and development using React Native. We also touch upon where they differ and how to bridge the gaps. Read on.
Let’s briefly set the context first. We will briefly touch upon what React Native is and how it differs from earlier hybrid frameworks.
React Native is a popular JavaScript framework that Facebook has created. You can use this open-source framework to code natively rendering Android and iOS mobile apps. You can use it to develop web apps too.
Facebook has developed React Native based on React, its JavaScript library. The first release of React Native came in March 2015. At the time of writing this article, the latest stable release of React Native is 0.62.0, and it was released in March 2020.
Although relatively new, React Native has acquired a high degree of popularity. The “Stack Overflow Developer Survey 2019” report identifies it as the 8th most loved framework. Facebook, Walmart, and Bloomberg are some of the top companies that use React Native.
The popularity of React Native comes from its advantages. Some of its advantages are as follows:
Are you wondering whether React Native is just another of those hybrid frameworks like Ionic or Cordova? It’s not! React Native is fundamentally different from these earlier hybrid frameworks.
React Native is very close to native. Consider the following aspects as described on the React Native website:
Due to these factors, React Native offers many more advantages compared to those earlier hybrid frameworks. We now review them.
