Clean Webpack Plugin Versions Save

Changes

• Added support for NodeJS 14
• Added support for webpack 5

Breaking changes:

• Dropped support for NodeJS 8
• Dropped support for webpack 3

• Removed Node 6 support
• Removed webpack 2 support
• cleanOnceBeforeBuildPatterns use emit hook instead of compile
• Do not clean files if webpack errors are present during initial build
• Replaced default export with named export CleanWebpackPlugin

// es modules
import { CleanWebpackPlugin } from 'clean-webpack-plugin';

// common js
const { CleanWebpackPlugin } = require('clean-webpack-plugin');

Relavant:

• README.md
• Additional v2 information

Changes:

• No configuration is needed for standard usage (cleans webpack's output.path)
• By default during webpack's watch mode, only files created by webpack are removed
• Because del is used, globbing is supported
• Plugin is tested directly via webpack
• All supported versions are tested
• Windows is tested via appveyor (no mocked tests)
• Complete build system including prepublish hooks and git prepush/commit hooks
• Written with Typescript

Additional notes:

• Moved to CircleCI because Travis CI was sold and looks to now be in maintenance mode.
• Replaced Coveralls with codecov because automatic build merging works. This is important because of windows/different webpack version testing
