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 🙏

uniconst

v1.0.3

Published

A lightweight TypeScript utility for unified constant management with value-label mapping and type-safe access

Readme

Uniconst

Uniconst 是一个轻量级的 TypeScript 工具库,旨在以类型安全且结构化的方式管理常量映射。它提供了一个基于类的直观 API,用于处理带有相关标签、值以及附加元数据(如颜色)的常量。

📌 特性

  • 类型安全:使用 TypeScript 泛型确保编译时类型检查。
  • 灵活的数据结构:支持带有可扩展字段的常量项。
  • 实用方法:提供便捷的方法用于获取值、提取选项和映射标签。
  • 可扩展的设计:易于集成到各种应用中,包括 UI 框架、后端服务和配置系统。

🛠️ 使用方法

创建一个常量定义对象并实例化 Uniconst 类:

import Uniconst from 'uniconst';

const Status = new Uniconst({
  PENDING: { label: 'Pending', value: 0 },
  APPROVED: { label: 'Approved', value: 1 },
  REJECTED: { label: 'Rejected', value: 2 }
});

console.log(Status.get('PENDING')); // { label: 'Pending', value: 0 }
console.log(Status.getOptions());   // 所有选项的数组
console.log(Status.toLabelMap());   // { '0': 'Pending', '1': 'Approved', '2': 'Rejected' }

✅ 优势

  • 强类型:确保只能访问有效的键和值。
  • 可扩展性:可以向常量项中添加自定义字段而不破坏现有逻辑。
  • 清晰的抽象:封装了处理带标签常量的常见模式。

📦 Installation

如果你计划将此包发布到 npm,可以通过以下方式安装:

npm install uniconst
