JAQT – JavaScript Queries and Transformations

In plain words

JAQT is a JavaScript library that simplifies searching, sorting, and filtering arrays of objects using a syntax inspired by GraphQL and SQL. Built with JavaScript Proxies, it requires no new query language—only standard JavaScript. Designed for developers of all levels, it offers a more accessible alternative to map, reduce, and sort functions while remaining compatible with existing array methods. The library is part of an experimental database project that uses JavaScript as its query engine.

GraphQL-style Array.select() and Array.where() for javascript - muze-nl/jaqt

In the maker’s words, at launch

Hi all, I've made a javascript library to simplify searching/sorting/filtering in arrays of objects. Its inspired by both GraphQL and SQL, but implemented using javascript Proxies. Instead of creating a new language, its all just javascript. I've made it as part of an experimental database, which uses…

  SQLite Plugin for Jekyll2024 · github.com · ▲227

  I love Jekyll, especially the Datafiles[0] feature, which lets you use CSV/JSON/YAML files and iterate through them. Mixed with the Jekyll Data Pages generator[1], which lets you create a page for every row in your dataset, it is a very powerful combination. However, Liquid is a terrible language for data-mangling, and simple filtering/sorting/merging can become very annoying. So I wrote a Jekyll SQLite plugin that lets you use the same data interface in Jekyll/Liquid, but backed by a SQLite file(s). It gives you the simplicity of the Baked Data pattern[2], and the…

  Talanoa▲340

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
