  3. autoComplete.js

    Simple autocomplete pure vanilla Javascript library.

    Project mention: autoComplete.js VS awesomplete - a user suggested alternative | libhunt.com/r/autoComplete.js | 2024-11-05
  4. csso

    CSS minifier with structural optimizations

    Project mention: CSSnano | news.ycombinator.com | 2024-09-15

    cssnano has had some complicated ownership turnover[0], I'm glad to see someone took the mantle again though.

    I do find that CSSO[1] with structural optimizations can be more effective still, perhaps that will be less true overtime though.

    I think once lightning CSS is more stable (in particular, some bugs are addressed around ordering) it will be the clear winner in this space though.

  5. fast-xml-parser

    Validate XML, Parse XML and Build XML rapidly without C/C++ based libraries and no callback.

    Project mention: Fast-XML-Parser: Validate XML, Parse XML and Build XML Rapidly | news.ycombinator.com | 2024-09-11
  6. delaunator

    An incredibly fast JavaScript library for Delaunay triangulation of 2D points

    Project mention: Generating Voronoi Diagrams Using Fortune's Algorithm (With Odin) | news.ycombinator.com | 2025-02-08

    I made an implementation in clojurescript that animates the algorithm as it goes a while back: https://voronoi.ajwerner.net/#/app-diagrams

    It’s a very beautiful algorithm.

    However, after that project I sort of came to dislike Fortune’s algorithm because it isn’t numerically stable with floating point numbers. If you have points that are colinear, or nearly colinear in fp, things can break. The delaunator is better in this regard iirc: https://github.com/mapbox/delaunator
