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 🙏

Readme

JsonBrook

流式解析Json数据
json-to-ast的实现启发而来

快速入门

import { createJsonBrook } from "json-brook";

const jsonBrook = createJsonBrook();

const sample = JSON.stringify(
	{
		a: 1001,
		b: "hello",
		c: [1, 2, 3],
		d: null,
	},
	null,
	4,
);

for (const char of sample) {
  jsonBrook.parse(char);
  console.log(jsonBrook.generate());
}

jsonBrook.end();
console.log(jsonBrook.generate());

API

根导出

createJsonBrook 返回一个JsonBrook实例,JsonBrook实例具有以下方法:

  • parse 接受单个字符,去解析Json数据
  • end 代表流结束,仅针对某些特殊场景,如纯数字形式的Json字符串
  • getRoot: 获取当前解析出的ast根节点
  • getCurrent 获取当前正在解析的ast节点
  • generate 生成当前解析结果,其中字符串和数字尽可能解析合法内容,对于true/false/null,只要识别开头就返回

tokenize导出

该模块主要是token解析相关方法

parse导出

该模块主要是ast解析相关方法

generate导出

该模块主要是默认生成方法
