bundlejs VS Rollup

Package Size Checker

I was closing out some long lived issues over on bundlejs, when issue #50 reminded me of the ongoing debate about how bundlejs should handle the ESM and CJS packages.

Still, I'm not really sure about its dependencies: it lists react and @tanstack/react-query (as opposed to @tanstack/query-core) and bundlejs reports 124KB gzipped. Also, while using it, you still need to refer to their react docs (that documentation is really good and has a lot of examples) but not everyone will be thrilled about checking a react documentation when they're using an angular package.

It's somewhere in between.

React as a lib and architecture _is_ platform-agnostic. The core logic is defined in the `react-reconciler` package. It contains all the implementation of rendering components, diffing trees, managing state, and running effects, as well as all the "Suspense" implementation.

However, the way `react-reconciler` works is that it's built _into_ each platform-specific renderer implementation. So, the size of `react-dom` is actually the size of `react-reconciler` + all the DOM-specific behavior.

A quick check of https://bundlejs.com/?q=react-reconciler suggests it's about 100K minified. https://bundlejs.com/?q=react-dom is 138K, so that tells me that the DOM-specific logic is 38K.

React Hook Form has no dependencies and a small bundle size. It has a gzipped bundle size of 12.12KB, according to bundlejs.

These are shameless plugs, but https://bundlejs.com and https://inthistweet.app. I built both tools specifically because I didn't find any other tools that solved the problems I kept running into.

Try https://bundlejs.com/ to see

bundlejs (pronounced bundle js) is a quick and easy way to treeshake, bundle, minify, and compress (in either gzip or brotli) your typescript, javascript, jsx and npm projects, while receiving the total bundles' file size.

Don't know of any but was going thru Adam Wathan's twits and replies. Found, https://github.com/okikio/bundle Looks medium sized.

Doesn't Rollup already use quite a bit of rust[0]? It's actually why I had to abandon it for a project, where they didn't offer binaries for our build platform and I needed to bundle, like 2 ES6 javascript libraries so I just grabbed esbuild instead.

Unlike Webpack, the Vite DevServer only compiles files when they are requested. It leverages ES module imports, which allow JS files to import other files without needing to bundle them together during development. When one file changes, only that file needs to be re-compiled, and the rest can remain unchanged. Project files are compiled with Rollup.js. Third-party dependencies in node_modules are pre-compiled using the ultra-fast esbuild bundler for maximum speed, and they are cached until the dependency version changes. Vite also provides a client script for hot module reloading.

Besides Webpack, there are many other popular web bundlers available, such as Parcel, Esbuild, Rollup, and more. They all have their own unique features and strengths, and you should make your decision based on the needs and requirements of your specific project. Please refer to their official websites for details.

The optimization points are very valid and good to keep in mind, no?

See for example:

The missing minification of identifiers and properties of the Vue instance in general were always bugging me in Vue 2, even when not using the class keyword.

This is a very valid consideration IMO.

In the Node.js ecosystem, bundling is typically handled by third-party tools rather than Node.js itself. Some of the most popular bundlers in the Node.js world include Webpack, Rollup, and Parcel, offering features like code splitting, tree shaking, and hot module replacement.

📦 Rollup for bundling

Bundling: Webpack, Parcel, Rollup

Rollup is another popular JavaScript module bundler focusing on high performance. It excels at tree-shaking and uses ES module syntax to generate more performant bundles than traditional module bundlers. In addition to JavaScript, Rollup supports bundling CSS and JSON as well. Rollup has more than 12 million weekly NPM downloads.

Vite (read as vit) is actually a combination of two great frontend tools - an immensely fast development server and a build command for shipping heavily optimized static assets using Rollup. Many developers have encountered the process of setting up a project using Create React App. While CRA can be useful for beginners due to its simplicity and abstraction of configuration, it has some drawbacks that outweigh its benefits, particularly its tendency to be bloated. Don't get me wrong, Vite is opinionated as well, but it's highly extensible through its Plugin API.
