  • How to Drag a Shape Along an SVG Ellipse Path: A Step-by-Step Guide

    I will use TypeScript with esbuild bundler, which is a fast and highly efficient builder for JavaScript and TypeScript.
  • Building an Extension System on the Web
    7 projects | | 2 Jun 2023
    Bundling extensions — in general, custom extension formats require custom bundling tools. Currently, as it’s still early, I put everything into a single JSON file with Node.js and esbuild bundler, but I’m exploring how to develop a custom Vite plugin for this purpose;
  • Do not drop Sass for CSS
    2 projects | | 2 Jun 2023
    Chris favours using the ESBuild bundler to work out the shortcomings. ESBuild can bundle CSS files into a single CSS file. ESBuild can transform your natively nested CSS to "flat" CSS -- this is important since nesting is not in Firefox currently. Therefore, with the aid of ESBuild, Chris has feature parity for his usage of Sass. The other Sass features like mixins and inheritance do not appeal to Chris.
  • [AskJS] Advantages of Rollup over other bundlers for creating libraries?
    3 projects | /r/javascript | 9 May 2023
    Rollup is highly configurable via plugins. It also supports a wide range of transpilation targets. However, it's written in JavaScript (well, TypeScript) so there's a ceiling on how fast it can go. esbuild and swc are orders-of-magnitude faster than Rollup.
  • JavaScript import maps are now supported cross-browser
    14 projects | | 3 May 2023
    Note that `deno bundle` is deprecated. You can almost replace it with esbuild but it currently lacks builtin support for import maps:

  • xtsz - a TS / JS file runner with support for HTTP/S imports
    5 projects | /r/node | 22 Apr 2023
    Want to import a package / file conveniently from or unpkg or directly from a GitHub repo for a one-off script (for example). To do this I created a custom ESBuild plugin to handle HTTP imports - that worked for ,js files. To support running both ESM and CJS, I use tsx.

  • Building a modern gRPC-powered microservice using Node.js, Typescript, and Connect
    15 projects | | 20 Apr 2023
    As we iterate on the definition, we are going to want a better developer experience for rebuilding the package on changes. Typically, for a “library” or “utility” style package, I’d reach for either unbuild’s stub concept or use esbuild/tsup/rollup to implement a more traditional watch/rebuild, but in this case, I’m watching a proto file that lives outsides of the source, which breaks assumptions of those tools.
  • Svelte frontend vs HTMX and hyperscript
    6 projects | /r/golang | 19 Apr 2023
    I use ESBuild ( as a library for my almost pure Go toolchain, and it covers my requirements for almost 2 years now. ESBuild is the Go tool used in Vite, an incredible tool that I stopped using when I discovered that ESBuild covered all my needs.
  • Buildless workflow through import maps (featuring Lit, Shoelace and more)
    2 projects | | 12 Apr 2023
    As we can see, we have two external dependencies and one internal tool. In the modern way of packaging our application, we would be of course required to package this project using some bundler like ESBuild or Rollup. But with import maps, we can instead utilize CDN's to deliver our packages and completely eliminate the bundling step.
