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 🙏

v1.0.5

Published

A TypeScript library for parsing JSON objects from streaming data, ideal for handling LLM outputs.

Readme

LLM JSON Stream Parser

一个轻量、高效且健壮的 TypeScript 库,用于从流中解析 JSON 数据。这在处理实时数据流、大型 JSON 文件或来自大型语言模型(LLM)的流式 JSON 响应时特别有用。

✨ 功能

  • 流式解析: 在数据到达时增量解析 JSON,无需将整个 JSON 文档加载到内存中。
  • 健壮性: 能正确处理在任意位置被切分的 JSON 数据块,包括在字符串、数字或多字节 Unicode 字符内部。
  • 高性能: 为速度和低内存开销而优化。
  • TypeScript 原生: 完全使用 TypeScript 编写,提供强类型和出色的编辑器集成。

📦 安装

通过 npm 安装开发依赖项:

npm i  llm-json-stream-parser

Example

import { tryParseJsonStreamAutoComplete } from "./index.js";
import { mockJsonStreamToCallback } from "./mock.js";


let content = "";
mockJsonStreamToCallback((chunk: string) => {
	content += chunk;
    tryParseJsonStreamAutoComplete(content, (obj) => {
        console.log("解析到完整 JSON对象:", JSON.stringify(obj || {}, null, 2));
    });
});
