API

• onBeforeBuild: array of scripts to execute before every build.
• onBuildError: array of scripts to execute when there is an error during compilation.
• onBuildStart: configuration object for scripts that execute before a compilation.
• onBuildEnd: configuration object for scripts that execute after files are emitted at the end of the compilation.
• onBuildExit: configuration object for scripts that execute after webpack's process is complete. Note: this event also fires in webpack --watch when webpack has finished updating the bundle.
• onWatchRun: configuration object for scripts that execute when webpack's run watch
• onDoneWatch: configuration object for scripts that execute after files are emitted at the end of the compilation with watch.
• onBeforeNormalRun: configuration object for scripts that execute on normal run without --watch option
• onAfterDone: configuration object for scripts that execute after done.
• onFailedBuild: configuration object for scripts that execute after error.
• onBeforeCompile: configuration object for scripts that execute before complite.

Default for all: {scripts: [],blocking: false,parallel: false}

• blocking (onBeforeBuild, onBuildStart, onBuildEnd, onBuildExit, onBuildExit, onWatchRun): block webpack until scripts finish execution.
• parallel (onBeforeBuild, onBuildStart, onBuildEnd, onBuildExit, onBuildExit, onWatchRun): execute scripts in parallel, otherwise execute scripts in the order in which they are specified in the scripts array.

Note: below combination is not supported.

{
 blocking: true
 parallel: true
} 

Other global params

• env: Object with environment variables that will be applied to the executables Default: { }
• logging: show output for internal messages. Default: true
• swallowError: ignore script errors (useful in watch mode) Default: false
• dev: switch for development environments. This causes scripts to execute once. Useful for running HMR on webpack-dev-server or webpack watch mode. Default: true
• safe: switches script execution process from spawn to exec. If running into problems with spawn, turn this setting on. Default: false

new WebpackShellPlugin({
      onBeforeNormalRun: {
        // ...
      },
      dev: false,
      safe: false,
      logging: true
    })
  ]
}

TypeScript

This project is written in TypeScript, and type declarations are included. You can take advantage of this if your project's webpack configuration is also using TypeScript (e.g. webpack.config.ts and webpack.config.js).

Function in scripts

how to use functions in the queue?

Example:

{
  {
    scripts: [
      // sync
      () => {
        console.log('run tTimeout 1');
        setTimeout(() => console.log('end Timeout 1'), 1000);
      },
      // async
      () => new Promise((resolve, reject) => {
        console.log('run async tTimeout');
        setTimeout(() => {
          console.log('end async tTimeout');
          resolve('ok');
        }, 1000);
      }),
    ],
      blocking: true
  }
}

// use exec
import * as os from 'os'
// ..
{
    safe: os.platform() === 'win32', // by default spawn is used everywhere. If you have problems try using safe: true
    scripts: [
      //...
    ]
    //  ...
}
