webpack-filter-warnings-plugin

Allows you to hide certain warnings from webpack compilations

Install

npm i -D webpack-filter-warnings-plugin

Usage

// webpack.config.js
const { FilterWarningsPlugin } = require('webpack-filter-warnings-plugin');

module.exports = {
  // ... rest of webpack config
  plugins: [
    new FilterWarningsPlugin({ 
      exclude: /any-warnings-matching-this-will-be-hidden/ 
    })
  ]
}

Using with Typescript

Webpack Filter Warnings Plugin is completely written in Typescript. As such, it exposes Typescript bindings.

Before using it, install webpack typings:

npm i --save-dev @types/webpack

yarn add --dev @types/webpack

Use ES imports:

// webpack.config.ts
import { FilterWarningsPlugin } from 'webpack-filter-warnings-plugin';

Options

Library exposes only one option: exclude. It may be one of RegExp, String or Function.

String as `exclude` filter

When passing string as exclude parameter, phrase is converted to wildcard and matches any phrase that contains it.

// webpack.config.js
module.exports = {
  // ... rest of webpack config
  plugins: [
    new FilterWarningsPlugin({ 
      exclude: 'hide me'
    })
  ]
}

This config will match any of Should hide me, Hide me, please, HiDe Me (filter is case insensitive) etc.

Function as `exclude` filter

// webpack.config.js
module.exports = {
  // ... rest of webpack config
  plugins: [
    new FilterWarningsPlugin({ 
      exclude: (input) => /.*hide.*/.test(input),
    })
  ]
}

Why not use the built in stats.warningsFilter option?

Currently karma-webpack does not respect the stats.warningsFilter option. Also when excluding all warnings, webpack still says Compiled with warnings. when all warnings are filtered. Hopefully this plugin will no longer need to exist one day.
