Node.js mock for react-native-config

We love react-native-config, a module which offers an elegant way to inject environment-specific variables to react-native.

We'd like to test react-native code in Node.js. As react-native-config contains native codes, it cannot be run in Nodejs environment. We provide a way to mock the module.

Installation

npm install --save-dev react-native-config-node

Usage (using mocha)

Create a compiler file using babel-register.

test/lib/babel-register.js

module.exports = require('babel-register')({
    plugins: ['react-native-config-node/transform']
})

Use it via command.

mocha --compilers js:./test/lib/babel-register test/spec/*.js

Alternatively, you can set mocha.opts.

--compilers js:./test/lib/babel-register

You can pass specific environment via NODE_ENV variable.

NODE_ENV=staging mocha --compilers js:./test/lib/babel-register test/spec/*.js

.env.staging will be loaded.

How it works

react-native-config-node/transform is a babel-plugin transforming the following code

import Config from `react-native-config`

into

import Config from `react-native-config-node`

react-native-config-node offers the same API as react-native-config using dotenv.
