What are @parcel/transformer-posthtml's main functionalities?

HTML Transformation

This feature allows you to transform HTML files using PostHTML plugins. By adding the transformer to your Parcel bundler configuration, you can apply various PostHTML plugins to modify your HTML files during the build process.

module.exports = function (bundler) {
  bundler.addAssetType('html', require.resolve('@parcel/transformer-posthtml'));
};

Custom PostHTML Plugins

You can add custom PostHTML plugins to the Parcel bundler configuration. This allows you to extend the functionality of the HTML transformation process by using custom plugins that perform specific tasks.

module.exports = function (bundler) {
  bundler.addAssetType('html', require.resolve('@parcel/transformer-posthtml'));
  bundler.addPostHTMLPlugin(require('posthtml-custom-plugin'));
};

HTML Minification

This feature allows you to minify HTML files using PostHTML plugins like 'posthtml-minifier'. By adding the minifier plugin to the configuration, you can reduce the size of your HTML files by removing unnecessary whitespace and comments.

module.exports = function (bundler) {
  bundler.addAssetType('html', require.resolve('@parcel/transformer-posthtml'));
  bundler.addPostHTMLPlugin(require('posthtml-minifier')({ collapseWhitespace: true }));
};
