介绍

Hey dev.to community! 👋

我很高兴向大家宣布 strfi —— 一个全面、零依赖、可树摇的集合，提供超过 150 个纯字符串工具，适用于现代 JavaScript 和 TypeScript 项目。

如果你厌倦了为简单的字符串任务（如生成 slug、转义 HTML、计算编辑距离或格式化字节）而引入庞大的库，strfi 将成为你轻量却强大的字符串工具箱。

• 零运行时依赖
• 完全可树摇 —— 只导入你需要的函数
• 出色的 TypeScript 支持，类型精确
• 在适用的情况下支持 Unicode 和地区敏感
• 无不安全的做法（没有 eval() 等）
• 极小的压缩后体积：约 22 KB
• 兼容所有环境：Node.js 16+、现代浏览器、Deno、Bun、React Native、Cloudflare Workers

安装

npm install strfi

或者使用 Yarn / pnpm：

yarn add strfi
# or
pnpm add strfi

使用示例

import {
  slugify,
  escapeHtml,
  capitalize,
  levenshteinDistance,
  formatBytes,
  camelCase,
  truncate,
  isEmail,
} from 'strfi';

console.log(slugify('Hello World! 🚀'));                     // "hello-world"
console.log(escapeHtml('alert("xss")'));                     // "<script>alert("xss")</script>"
console.log(capitalize('javascript'));                     // "Javascript"
console.log(levenshteinDistance('kitten', 'sitting'));     // 3
console.log(formatBytes(1500000));                         // "1.43 MB"
console.log(camelCase('foo-bar_baz'));                     // "fooBarBaz"
console.log(truncate('Very long text here', { length: 10 })); // "Very lo..."
console.log(isEmail('test@example.com'));                  // true
