    This also means that whatever build tooling must produce the distribution file with a .cjs file extension. This might necessitate chaining multiple build tools or adding a subsequent step to move/rename the file to have the .cjs file extension (ex mv ./dist/index.js ./dist/index.cjs)3. This can be worked around by adding a subsequent step to move/rename those outputted files (ex Rollup or a simple shell script).
  • Make SvelteKit bundle all *.ts files into a single bundle.js
    1 project | reddit.com/r/sveltejs | 1 Jan 2022
    I think Rollup is where the code-splitting is happening so you will need to address the problem there. Here is an ongoing discussion that seems to have some solutions: https://github.com/rollup/rollup/issues/2756
  • Vite, the hassle-free alternative to Webpack
    4 projects | dev.to | 12 Nov 2021
    Vite doesn't create itself the bundles. Under the hood, it uses two tools: Esbuild while you're developing, and Rollup.js to create the production bundle.
  • Rakkas: Next.js alternative powered by Vite
    13 projects | dev.to | 14 Oct 2021
    If you're not familiar with Vite, it's an instance of a new class of tools, sometimes called non-bundlers, that leverage modern browsers' native EcmaScript modules support to do away with the bundling during development. This results in instant server start and much faster updates than traditional bundlers like Webpack, Rollup, or Parcel. These new tools (another example is Snowpack) improve developer experience so much that, once you try, you will never want to go back to your old tooling.
  • The Ultimate Guide to Getting Started with the Rollup.js JavaScript Bundler
    5 projects | dev.to | 6 Oct 2021
    Rollup.js is a Node.js module bundler most often used for client-side JavaScript running in the browser. (You can bundle Node.js scripts but there are fewer reasons to do so). The tool compiles all your JavaScript source files into a single bundle for inclusion in your production web pages.
  • Major updates for bundle.js.org v0.0.3

    I used monaco-editor for the code-editor, esbuild and rollup as bundler and treeshaker respectively, pako as a js port of the zlib and gzip libraries, pretty-bytes to convert the gzip size to human readable values, and countapi-js to keep track of the number of page visits, in a private and secure way.

    If you're using a bundler (like Rollup or webpack), you can import the Appwrite module when you need it:
  • Created CLI Tool that Creates/Remove GitHub Labels

    Export as a javascript module, making your work fully tree-shakable for consumers capable of using es6 imports (like Rollup, Webpack, or Parcel)
  • What does it take to support Node.js ESM?
    9 projects | dev.to | 12 Aug 2021
    There are workarounds, but nothing actually works in 100% of the possible use-cases (see for example, ts-jest issue), and for that reason, we recommend tooling that enables this type of building without needing any workaround, usually using Rollup and/or esbuild.
  • [AskJS] How can i structure my js library?
    4 projects | reddit.com/r/javascript | 20 Jul 2021
    I agree, although, at this point, it might be better to use a bundler that uses ESM in the final bundle like Vite, Rollup, or Snowpack. Rollup works better for libraries than Webpack, at least in my opinion.

  • My personal package manager odyssey

    For my project I used parcel bundler version 1.x from the beginning and was quite happy with it. Zero configuration was great and I'm a supporter of smaller projects more innovative projects that do something different than the big players (e.g. trello > jira, pixelmater > photoshop).

    Parcel is a zero-configuration build tool that will help us to compile the Sass and JavaScript files. I decided to drop Gulp or Webpack because the complexity and the maintenance were a big-time consumer.

    You might have heard about the new kid on the block of build tools for web - Parcel. It combines great scalable architecture with amazing zero-configuration developer experience while being lightning fast at the same time. You might have even thought about trying it out and maybe moving one of your TypeScript projects to it.

  • Building a Webpack alternative in F#
    14 projects | dev.to | 16 Dec 2021
    At the time I had been exploring alternatives to Webpack like fuse-box, parcel, and esbuild. Around the same time I was made aware aware that browsers had already implemented [ESM modules], so technically as long as you produced HTML, CSS, and JS you didn't need any kind of pre-processing at all.

    I have written a post about setting up a React project using Parcel as a bundler which can give a more detailed walkthrough about getting a React application up and running from scratch. There are multiple ways to do this but some of the more common build tools include Webpack, Parcel, and Snowpack.
  • PR 1 for release 0.3
    2 projects | dev.to | 19 Nov 2021
    For our release 0.3 project we were to make a pull request for a external project outside of our class's repos and one pull request for an internal repo. For my external PR I worked and still am working on a library project that my professor maintains outside of Seneca called Filer. Filer is a drop-in library that works like node's fs module but for browsers. The issue I was working on was making a migration of parcel 1 to parcel 2.

What are some alternatives?

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

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

esbuild - An extremely fast JavaScript and CSS bundler and minifier

Snowpack - ESM-powered frontend build tool. Instant, lightweight, unbundled development. ✌️

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.

gulp - A toolkit to automate & enhance your workflow

browserify - browser-side require() the node.js way

FuseBox - A blazing fast js bundler/loader with a comprehensive API :fire:
