Jq-in-the-browser -– jq compatible JSON processor in JavaScript

In plain words

Jq-in-the-browser is a JavaScript port of the jq JSON processor designed for web use. It processes JavaScript objects directly rather than serialized data and is written from scratch to keep file size small at approximately 33 kB uncompressed and 6.1 kB gzipped. The tool allows developers to run jq-compatible queries on data structures in the browser using a simple import and function call syntax.

From the sources

Instead of processing serialized data, jq-in-the-browser processes JavaScript objects. It is written from scratch and is relatively small. (~33 kB, ~6.1 kB gzipped) import jq from 'jq-in-the-browser' const query = jq ( '{"names": [.[] | .name]}' ) query ([ { "name" : "Mary" , "age" : 22 }, { "name" : "Rupert" , "age" : 29 }, { "name" : "Jane" , "age" : 11 }, { "name" : "John" , "age" : 42 } ]) Output: { "names" : [ "Mary" , "Rupert" , "Jane" , "John" ] } Comparison with alternatives jq-web jq-web is an emcripten port of jq, thus it implements all of its features … but it’s also too big for many purposes (in the megabytes) jq-in-the-browser is written from scratch, but is more limited in…from kantord.github.io

  I'm working on a tool that will probably involve querying JSON documents and I'm asking myself how to expose that functionality to my users. I like the power of `jq` and the fact that LLMs are proficient at it, but I find it right out impossible to come up with the right `jq` incantations myself. Has anyone here been in a similar situation? Which tool / language did you end up exposing to your users?

  Hey HN! Jaiqu is an AI agent for creating repeatable JSON transforms using jq query language syntax. Jaiqu translates complex JSON structures into repeatable jq queries. jq is a command line utility built for fast, reliable JSON queries. Jaiqu takes advantage of the LLMs for both constructing jq queries as well as using feedback to fix errors/invalid results if those queries are incorrect. Writing code to parse JSON is super annoying. It usually involves manually reading huge JSON balls, parsing the keys in a language of your choice, and pulling the data manually. Also, you're likely to…
