Case Sensitive Paths - Webpack Plugin

This Webpack plugin enforces the entire path of all required modules match the exact case of the actual path on disk. Using this plugin helps alleviate cases where developers working on OSX, which does not follow strict path case sensitivity, will cause conflicts with other developers or build boxes running other operating systems which require correctly cased paths.

Previous iterations on this same idea provide the basis for this plugin, but unfortunately do not properly check case on the entire path. This plugin fixes that. Example output:

ERROR in ./src/containers/SearchProducts.js Module not found: Error: [CaseSensitivePathsPlugin] /Users/example/yourproject/src/components/searchProducts/searchproducts.js does not match the corresponding path on disk /Users/example/yourproject/src/components/searchproducts @ ./src/containers/SearchProducts.js 9:22-84

Install

npm install --save-dev case-sensitive-paths-webpack-plugin

Usage

var CaseSensitivePathsPlugin = require('case-sensitive-paths-webpack-plugin');
 
var webpackConfig = {
    plugins: [
        new CaseSensitivePathsPlugin()
        // other plugins ...
    ]
    // other webpack config ...
}

Want more information? Pass {debug: true} to the plugin like so:

new CaseSensitivePathsPlugin({debug: true})

It will output every directory it reads, as well as a sum total of filesystem operations. This is mostly useful for internal debugging of the plugin, but if you find it useful, more power to you.

Demo
