Webpack/V5/Migrate Library Target To Library Object

1.0.0Last update Sep 6, 2024

This codemod migrates the output.library and output.libraryTarget properties in Webpack configurations to the new format required by Webpack 5. It changes output.library to output.library.name and output.libraryTarget to output.library.type.

Example

Before

module.exports = {
  output: {
    library: 'MyLibrary',
    libraryTarget: 'commonjs2',
  },
};

After

module.exports = {
  output: {
    library: {
      name: 'MyLibrary',
      type: 'commonjs2',
    },
  },
};

Before

module.exports = {
  output: {
    library: 'MyLibrary',
    libraryTarget: 'commonjs2',
    filename: 'bundle.js',
  },
};

After

module.exports = {
  output: {
    library: {
      name: 'MyLibrary',
      type: 'commonjs2',
    },

    filename: 'bundle.js',
  },
};

Before

module.exports = {
  output: {
    library: 'MyLibrary',
  },
};

After

module.exports = {
  output: {
    library: {
      name: 'MyLibrary',
      type: undefined,
    },
  },
};

Before

module.exports = {
  output: {
    library: 'MyLibrary',
    libraryTarget: 'umd',
    path: './dist',
  },
};

After

module.exports = {
  output: {
    library: {
      name: 'MyLibrary',
      type: 'umd',
    },

    path: './dist',
  },
};
