webpack-validator

Validate your webpack configs with joi

Note: webpack v2 has built-in validation for configuration (you don't have to do anything, it just works). Due to this, webpack-validator is unlikely to make significant changes. While pull requests will be reviewed and can be merged (for webpack v1 support), project maintainers are unlikely to put a lot of much effort into the maintenance of the project.

Writing webpack configs is brittle and error-prone. This package provides a joi object schema for webpack configs. This gets you a) static type safety, b) property spell checking and c) semantic validations such as "loader and loaders can not be used simultaneously" or "query can only be used with loader, not with loaders".

You're very welcome to give feedback & PR's.

Example

Take this simple webpack config. It has a tiny, hard to spot error. Can you find it?

var config = {
  module: {
    loaders: [
      { test: /\.js$/, loaders: 'babel-loader', exclude: /node_modules/ }
    ]
  },
  output: {
    library: 'Redux',
    libraryTarget: 'umd'
  },
  plugins: [
    new webpack.optimize.OccurenceOrderPlugin(),
    new webpack.DefinePlugin({
      'process.env.NODE_ENV': JSON.stringify(env)
    })
  ]
};
