webpack-loader-denolint v1.1.3

webpack-loader-denolint

A Webpack loader to lint entry points and all imported files with denolint.

A lot faster than eslint-loader, handling both JavaScript and TypeScript sources. Use rollup-plugin-denolint for Rollup. Use esbuild-plugin-denolint for esbuild. Or simpler, just the command-line denolint.

Synopsis

module.exports = {
  // the rest of the configuration
  module: {
    rules: [
      {
        test: /\.js$/,
        loader: 'webpack-loader-denolint'
      },
      // other loaders
    ]
  }
}

Installation

Make sure that you use Node.js 14 or newer and Webpack 5 or newer. Use your favourite package manager - NPM, PNPM or Yarn:

npm i -D webpack-loader-denolint
pnpm i -D webpack-loader-denolint
yarn add -D webpack-loader-denolint

Usage

Create a webpack.config.js configuration file and enable the loader:

module.exports = {
  // the rest of the configuration
  module: {
    rules: [
      {
        test: /\.js$/,
        exclude: ['tests'],
        loader: 'webpack-loader-denolint',
        options: {
          rules: {
            exclude: ['no-unused-vars']
          }
        }
      },
      // other loaders
    ]
  }
}

Then call webpack either via the command-line or programmatically.
