    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.

  • Build a Vite 5 backend integration with Flask
    11 projects | dev.to | 25 Feb 2024
    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.

  • How to rewrite classes using closures in JavaScript

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

    See for example:

    https://github.com/rollup/rollup/issues/349

    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 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.
  • How to build and publish React TypeScript NPM packages with Vite
    4 projects | dev.to | 4 Jun 2023
    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.

    In the Changelog Podcast episode referenced above, Dan Abramov alluded to Parcel working on RSC support as well. I couldn’t find much to back up that claim aside from a GitHub issue discussing directives and a social media post by Devon Govett (creator of Parcel), so I can’t say for sure if Parcel is currently a viable option for developing with RSCs.

    Once you build a simple Vite backend integration, try not to complicate Vite's configuration unless you absolutely must. Vite has become one of the most popular bundlers in the frontend space, but it wasn't the first and it certainly won't be the last. In my 7 years of building for the web, I've used Grunt, Gulp, Webpack, esbuild, and Parcel. Snowpack and Rome came-and-went before I ever had a chance to try them. Bun is vying for the spot of The New Hotness in bundling, Rome has been forked into Biome, and Vercel is building a Rust-based Webpack alternative.

  • Building Node.js applications without dependencies

    I’ve tried something similar on the frontend side: I decided to build a UI for Ollama.ai using only HTML, CSS, and JS (Single-Page Application). The goal is to learn something new and have zero runtime dependencies on other projects and NPM modules. Only Node and Parcel.js (https://parceljs.org/) are needed during development for serving files, bundling, etc. The only runtime dependency is a modern browser.

    Here's what I have found so far:

    - JavaScript (vanilla) is a viable alternative to React.js

    There are projects attempting to do more things. I've really enjoyed Parcel (https://parceljs.org). But it won't handle things like linting or unit testing, which you may or may not want. Vite is also pretty popular (https://vitejs.dev/), and it has a test runner.

    Thing is, most of the problems described in the post aren't related to low-JS front-end libraries like HTMX or alpine. You can write React without a linter, bundler, build tool, unit testing, or linting. But with any of these projects at scale, you start wanting more:

    - If you want to write unit tests in JS, you need to choose a test runner (probably Jest or Vitest -- until the built-in node testing module becomes more common).

    - If you want linting, you need a linter (probably Eslint). If you want type safety, you need a type checker (probably Typescript).

    - If you want to create smaller JS files to ship to production and to automatically handle assets, you need a bundler.

    - If you want to use new language features while supporting old browsers, you need polyfills.

    - If you want to use all these things together, you need something to bring it together (like Webpack).

    So it really depends what you need! You may not need any. But as you can imagine, in many professional projects with multiple developers it's very nice to have unit tests, linting, and type checking :) (And you start caring about end-user performance a lot more, in which case optimizing the shipped bundle is important.)

    Take all that, and then compare to a language like Rust, which has most of the "ecosystem stuff" built-in. In Rust, you get the test runner, the linter, dependency manager, type checker, and documentation tool all included. Easy! Thankfully, Rust doesn't have to care about whether users support modern language features (because it compiles down to lower code ahead of time), or whether the binary shipped to the client is optimally organized for downloading immediately over the internet.

    It's a problem in JS because A) you have to care about more problems than many other languages since JS needs to load instantly over the wire in a web browser, and B) there is a huge amount of choice and not a lot of standardization in web tools. (And what standardization there is (Node, npm), there are still competitors trying to even further reduce the pain points.)

    I think that in ten more years, we'll be in a better place, because there is push back (like this post!) against these problems, which will encourage more tools trying to solve the explosion of tools. Which seems counterintuitive, but these tools were created to solve very real problems. So I see it as a pendulum which has swung too far, but will likely swing back to a more balanced place. And you see that with tools like Vite gaining popularity.

  • Whatever It Takes
    1 project | dev.to | 24 Jun 2023
    My first challenge here was the migration from vanilla JS to utilizing tools like Parcel and React. React, I was a bit familiar with; however, I had never heard of Parcel.js in my life. Several days were spent troubleshooting why my build process was not working on Netlify before I finally found out that I had to set up my Netlify Build Settings specifically for using a bundler like Parcel.js

What are some alternatives?

When comparing Rollup and parcel you can also consider the following projects:

esbuild - An extremely fast bundler for the web

vite - Next generation frontend tooling. It's fast!

gulp - A toolkit to automate & enhance your workflow

tsup - The simplest and fastest way to bundle your TypeScript libraries.

webpack - A bundler for javascript and friends. Packs many modules into a few bundled assets. Code Splitting allows for loading parts of the application on demand. Through "loaders", modules can be CommonJs, AMD, ES6 modules, CSS, Images, JSON, Coffeescript, LESS, ... and your custom stuff.

Next.js - The React Framework

Snowpack - ESM-powered frontend build tool. Instant, lightweight, unbundled development. ✌️ [Moved to: https://github.com/FredKSchott/snowpack]
