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 🙏

介绍

env-config-jsonc 是一个轻量级 Node.js 环境配置加载工具,支持 JSONC(JSON with Comments) 格式的配置文件解析。它允许开发者通过简单的 API 加载和合并多层级配置,并自动挂载到 Node.js 的 process.envconfig 上,方便全局访问

✨ 特性

  • 支持 JSONC 格式(允许注释、尾随逗号等)
  • 🔄 深度合并配置(递归合并对象,数组直接覆盖)
  • 仅依赖 jsonc-parser(轻量)
  • 🚀 简单 API(一行代码加载配置)
  • 📦 TypeScript 友好(包含类型定义)

安装

npm install env-config-jsonc

使用

// 在项目根目录创建jsonc文件
//env.config.jsonc
{
    "key1": 1,//支持注释
    "key2": {
        "a": "value",
        "b": [1,2,3],
        "c": [{},{},{}],
        "d":123
    }
}
//local.env.config.jsonc
{
    "key1": 10,
    "key2": {
        "a": "newvalue",
        "b": [4,5,6],
        "newkey":"",
        "d": null
    },
    "key3":""
}
import loadconfig from 'env-config-jsonc';

// 加载默认配置文件 (env.config.jsonc)
loadconfig();

// 或指定自定义路径
loadconfig({ path: 'local.env.config.jsonc' });

// 或根据 NODE_ENV 加载不同配置
loadconfig({ path: `${process.env.NODE_ENV}.env.config.jsonc` });//如果文件不存在 将自动忽略

// 访问配置
console.log(process.envconfig);
// 后面加载的配置文件将与之前加载的配置文件深度合并
// 合并规则
// 相同字段:后者覆盖前者(基础类型、数组直接替换)
// 对象字段:递归合并子属性
// 新增字段:自动合并到最终配置
// 结果示例(使用上方示例配置):
// {
//   key1: 10,
//   key2: {
//     a: 'newvalue',
//     b: [ 4, 5, 6 ],
//     c: [ {}, {}, {} ],
//     d: null,
//     newkey: ''
//   },
//   key3: ''
// }
