Webpack/V5/Set Target To False And Update Plugins

1.0.1Last update Apr 23, 2025

This codemod migrates the target property in Webpack configurations from a function to false and moves the function to the plugins array.

In Webpack 4, it was possible to set the target property to a function. However, in Webpack 5, this approach is no longer supported. Instead, the target should be set to false, and the function should be included in the plugins array. This codemod automates the transformation of Webpack configurations to adhere to the new specification.

Example

Before

module.exports = {
  target: WebExtensionTarget(nodeConfig),
};

After

module.exports = {
  target: false,
  plugins: [WebExtensionTarget(nodeConfig)],
};

Before

const WebExtensionTarget = require("webpack-extension-target");

module.exports = {
  target: WebExtensionTarget(nodeConfig),
  mode: "development",
  output: {
    filename: "bundle.js",
  },
};

After

const WebExtensionTarget = require("webpack-extension-target");

module.exports = {
  target: false,
  plugins: [WebExtensionTarget(nodeConfig)],
  mode: "development",

  output: {
    filename: "bundle.js",
  },
};

Before

module.exports = {
  target: WebExtensionTarget(nodeConfig),
  optimization: {
    splitChunks: {
      chunks: "all",
    },
  },
};

After

module.exports = {
  target: false,
  plugins: [WebExtensionTarget(nodeConfig)],

  optimization: {
    splitChunks: {
      chunks: "all",
    },
  },
};

Before

module.exports = {
  target: CustomTargetFunction(config),
};

After

module.exports = {
  target: false,
  plugins: [CustomTargetFunction(config)],
};
