ignore-loader

What is ignore-loader?

The ignore-loader npm package is a webpack loader that allows you to ignore specific files or modules during the build process. This can be useful for excluding files that are not needed in the final bundle, such as test files, large assets, or platform-specific code.

What are ignore-loader's main functionalities?

Ignore specific files

This feature allows you to ignore files that match a specific pattern. In this example, all files ending with .test.js will be ignored during the build process.

module.exports = {
  module: {
    rules: [
      {
        test: /\.test.js$/,
        loader: 'ignore-loader'
      }
    ]
  }
};

Ignore specific modules

This feature allows you to ignore specific modules. In this example, any module that matches the pattern 'some-large-module' will be ignored during the build process.

module.exports = {
  module: {
    rules: [
      {
        test: /some-large-module/,
        loader: 'ignore-loader'
      }
    ]
  }
};

Other packages similar to ignore-loader

null-loader

The null-loader package is similar to ignore-loader in that it allows you to ignore specific files or modules. However, instead of ignoring them, it replaces the content with an empty module. This can be useful if you want to ensure that the ignored files do not affect the build process in any way.

file-loader

The file-loader package is used to emit files as separate assets in the build process. While it is not used to ignore files, it can be used in conjunction with ignore-loader to manage which files are included or excluded from the final bundle.

url-loader

The url-loader package is similar to file-loader but can inline files as base64 URIs if they are below a certain size. This can be useful for managing small assets. Like file-loader, it can be used alongside ignore-loader to control the inclusion of files in the build.
