config-webpack-plugin

💫 Merge one or more configuration files together with environment variables too.

Installation

npm install config-webpack-plugin --save-dev

How it works?

webpack.config.js:

const ConfigPlugin = require('config-webpack-plugin')
 
module.exports = {
    plugins: [
        new ConfigPlugin([
            './config.js',
            './config.local.js'
        ])
    ]
}

1. The config-webpack-plugin will merge all specified configuration file contents from right to left, thus creating a ‘merged configuration’.
2. If the ‘merged configuration’ contains a key matching a current environment variable then the related value will be replaced by the environment variable's value.
3. Finally, the config-webpack-plugin will intercept the ‘main configuration’ file (the first specified) during webpack's module resolution and will replace its source with the ‘merged configuration’.

Usage

Single configuration

const ConfigPlugin = require('config-webpack-plugin');
 
module.exports = {
    plugins: [
        new ConfigPlugin('./config.js')
    ]
}

Multiple configuration

const ConfigPlugin = require('config-webpack-plugin');
 
module.exports = {
    plugins: [
        new ConfigPlugin([
            './config.js',
            './config.local.js'
        ])
    ]
}

FAQ

What is a configuration file?

A module that export an object with key/value pairs that looks like:

module.exports = {
    API_BASE_URL: 'http://localhost/',
    NODE_ENV: 'development',
    AUTH_SPOOFED: true,
}

Does my configuration file gets modified?

No.

Roadmap

• Add test. Please!
• Add CI. Please!
• Support multiple file (new ConfigPlugin(['./config.default.js', '.config.local.js'])).
• Support JSON file too ♥️, because they are prettiest for configuration.
• Add a static website using GitHub Pages (why not?).
