Parcel
ELI5 — The Vibe Check
Parcel is the zero-config bundler that just works. No webpack.config.js, no rollup plugins, nothing. Point it at your entry file and it figures out the rest. It's the 'I don't want to configure build tools' bundler, and honestly, that's valid.
Real Talk
Parcel is a zero-configuration web application bundler that automatically handles JavaScript, CSS, HTML, images, and other asset types. It features automatic code splitting, hot module replacement, tree shaking, and uses a multi-core compilation pipeline for fast builds.
