Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

@dsj9/jsonpath-rfc9535

v1.0.1

Published

High-performance JSONPath RFC 9535 implementation

Readme

@dsj9/jsonpath-rfc9535

A dependency-free TypeScript implementation of JSONPath RFC 9535 for Node.js 22.12 and newer. ESM and CommonJS are supported.

Install

npm install @dsj9/jsonpath-rfc9535

Usage

import { compile, query } from '@dsj9/jsonpath-rfc9535';

const document = {
  books: [
    { title: 'Kindred', price: 9 },
    { title: 'Dune', price: 12 },
  ],
};

query('$.books[[email protected] < 10].title', document);
// { nodes: [{ value: 'Kindred', path: "$['books'][0]['title']" }] }

const titles = compile('$.books[*].title');
titles.query(document);

query(selector, document) parses and evaluates a selector. compile(selector) parses it once for reuse. Invalid selectors throw JsonPathSyntaxError.

Results contain each selected value and its RFC 9535 Normalized Path. The standard functions and RFC 9485 I-Regexps are supported. Custom function extensions are not currently supported.

Development

npm ci
npm run check
npm run bench

Benchmark notes are in BENCHMARKS.md.

Correctness is tested against the JSONPath Compliance Test Suite. Benchmarks include a comparison with jsonpath-rfc9535.
