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.
From a developer experience perspective, it's worth noting that Next.js was built using webpack for bundling, which has struggled to maintain performance. Therefore, when changing something in the code, reload times can be very slow. For this reason, the Next.js team has been working on getting full compatibility on its own bundler, Turbopack. As of Next.js 14, Turbopack is still considered beta but is much faster than the default experience with webpack.

html5-boilerplate
A professional front-end template for building fast, robust, and adaptable web apps or sites.
I learned this back when HTML5 was brand new around 15-ish years ago. If you wanted to use the new tags like , the only “polyfill” needed was some css styles. You can see it in the early versions of the HTML5 Boilerplate:
https://github.com/h5bp/html5-boilerplate/blob/v0.9/css/styl...
I realized that I could just make up tags and style them and it was work.

OP/author here! Apologies about the malware and captcha. It looks like my site was exploited by CVE-2026-26980 affecting all Ghost sites pre v6.19 [1][2] An API key was hijacked to inject malicious JS into every page that looks like a cloudflare captcha; it seems that the JS only targeted windows users, so I didn't catch it before I shared the post widely.
The site has been upgraded to 6.44 to close the vulnerability, I rotated every API key and account credential, and both manually and programmatically scrubbed every instance I could find of the code injection across the database. I think we're clear now!
Sorry to anyone caught by this and thank you to folks for flagging it (and thanks to the HN team for letting me follow up on this after comments were closed). I'm seriously mortified. X_X

Project mention: How to Build a Dependency Map of a Legacy Codebase Using AI Tools | dev.to | 2026-05-09
137Foundry provides legacy modernization services that include dependency mapping as a foundational assessment phase. Prettier and ESLint are useful companion tools for enforcing code style consistency as the refactoring proceeds. Node.js and Python.org official documentation are authoritative references for understanding the import and module systems of those runtimes.

For web stuff, I enjoy https://htmx.org
so Go + Templ + HTMX (aka the GOTH stack)
Or, if you prefer more of a power tools feel, then HTMX and Raku in functional style (https://harcstack.org) maybe to your liking. Which I call the Crotch Rocket of the programming world.
