How do I create a custom Webpack plugin?

To create a custom Webpack plugin, you need to extend the Plugin class and implement the apply method.

What should I include in the apply method?

In the apply method, you can tap into the Webpack lifecycle hooks to modify the build process.

Can you give me an example of a simple plugin?

Sure! Here's a simple plugin that logs the build process:

class MyPlugin {
  apply(compiler) {
    compiler.hooks.emit.tap('MyPlugin', (compilation) => {
      console.log('The build is starting!');
    });
  }
}

How do I test my plugin?

You can test your plugin by creating a sample Webpack configuration and running it with your plugin included.
