`DeadcodePlugin` for Webpack

Plugin finds dead code in your project trying compare modules used at Webpack bundle with file system.

Install dependencies

npm istall

Build demo app from ./src/*

npm run build

See generated unused.json - it will contain potential dead code from your project

Add into your webpack.config.ts DeadcodePlugin and pass config options:

const config: webpack.Configuration = {
    ...
    plugins: [
        new DeadcodePlugin(options),
    ],
    ...
}

options is an object of type PluginOptions:

type PluginOptions = {
    outputFile: string, // 'unused.json' by default
    rootDir: string // 'src' by default
}
