Parcel Bundler: The Complete Tutorial

Set up a basic to-do list app by creating a new project folder and HTML, CSS, and JavaScript files, then reference them in HTML for future features and parcel integration.

Learn what assets are in parcel bundler, how types are bundled, and how to import json to render a to-do list in a web app.

Configure postcss to add vendor prefixes automatically with autoprefixer, create postcss.config.js and a browserslist file specifying the last five versions, and verify shadow styling across browsers.

Learn how to refactor a single JavaScript file into ECMAScript 6 modules, exporting and importing data, UI rendering, and onload event handlers for a cleaner, scalable codebase.

Learn to use the latest JavaScript features through Babel, installing Babel and a pipeline-operator plugin to transpile modern syntax into widely supported JavaScript for immediate use.

Apply tree shaking by importing an exported Lodish library function via ES6 modules. This reduces the production bundle size, though the feature is experimental and should be tested.

Enable gzip compression for parcel bundler using a plugin to deliver compressed files via the accept-encoding header, which the browser decompresses before rendering.

Integrate the Express framework into a web application, generate an HTML file with its assets, and explore publishing the site by serving the app with Express or other technologies.

Learn to serve static files—css, javascript, and images—in an Express app by using the static middleware with a static folder, and update html references.

Learn to integrate Parcel Bundler with React by creating a project, installing Parcel and React, configuring Babel, building a simple hello world component, and running development and production builds.
