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 🙏

@lytjs/common-http

v6.6.0

Published

Lightweight HTTP client based on native fetch API

Readme

@lytjs/common-http

基于原生 fetch API 的轻量级 HTTP 客户端,支持拦截器、超时、数组查询参数等功能。

安装

pnpm add @lytjs/common-http

快速开始

基础使用

import { http, getJson, postJson } from '@lytjs/common-http';

// 使用默认 http 实例发送请求
const response = await http.get('/api/users');
console.log(response.data);

// 或使用便捷的 JSON 方法
const data = await getJson('/api/users');

创建自定义客户端

import { createHttpClient } from '@lytjs/common-http';

const apiClient = createHttpClient({
  baseURL: 'https://api.example.com',
  headers: {
    Authorization: 'Bearer YOUR_TOKEN',
    'Content-Type': 'application/json',
  },
  timeout: 5000,
});

const users = await apiClient.get('/users');

API

便捷方法

| 方法 | 说明 | | ------------------------------------ | ------------------------------------ | | get<T>(url, options?) | 发送 GET 请求 | | post<T>(url, data?, options?) | 发送 POST 请求 | | put<T>(url, data?, options?) | 发送 PUT 请求 | | patch<T>(url, data?, options?) | 发送 PATCH 请求 | | del<T>(url, options?) | 发送 DELETE 请求 | | getJson<T>(url, options?) | 发送 GET 请求并直接返回 JSON 数据 | | postJson<T>(url, data?, options?) | 发送 POST 请求并直接返回 JSON 数据 | | putJson<T>(url, data?, options?) | 发送 PUT 请求并直接返回 JSON 数据 | | patchJson<T>(url, data?, options?) | 发送 PATCH 请求并直接返回 JSON 数据 | | deleteJson<T>(url, options?) | 发送 DELETE 请求并直接返回 JSON 数据 |

HttpClient 类

import { HttpClient, createHttpClient } from '@lytjs/common-http';

const client = new HttpClient({
  baseURL: 'https://api.example.com',
  headers: { 'X-API-Key': 'your-key' },
  timeout: 10000,
});

// 或者使用工厂函数
const client = createHttpClient({
  baseURL: 'https://api.example.com',
});

请求选项

interface RequestOptions {
  headers?: Record<string, string>;
  params?: Record<string, string | number | boolean | Array<string | number | boolean>>;
  timeout?: number;
  signal?: AbortSignal;
  responseType?: 'json' | 'text' | 'blob' | 'arraybuffer';
}

响应格式

interface HttpResponse<T> {
  data: T;
  status: number;
  statusText: string;
  headers: Record<string, string>;
  ok: boolean;
}

特性

1. 数组查询参数支持

import { get } from '@lytjs/common-http';

// 数组参数会被正确地处理为多个相同键名的查询参数
await get('/api/users', {
  params: {
    ids: [1, 2, 3],
    tags: ['admin', 'user'],
  },
});
// 结果: /api/users?ids=1&ids=2&ids=3&tags=admin&tags=user

2. 拦截器

import { http } from '@lytjs/common-http';

// 添加请求拦截器
http.use({
  request(config) {
    config.headers['X-Request-ID'] = Math.random().toString(36);
    return config;
  },
});

// 添加响应拦截器
http.use({
  response(response) {
    console.log('请求成功:', response.status);
    return response;
  },
  error(error) {
    console.error('请求失败:', error);
    throw error;
  },
});

3. 请求取消

import { http } from '@lytjs/common-http';

const controller = new AbortController();

// 5 秒后取消请求
setTimeout(() => controller.abort(), 5000);

try {
  await http.get('/api/slow-endpoint', {
    signal: controller.signal,
  });
} catch (err) {
  if (err.name === 'AbortError') {
    console.log('请求已取消');
  }
}

4. 超时控制

import { http, createHttpClient } from '@lytjs/common-http';

// 单次请求超时
await http.get('/api/slow', { timeout: 3000 });

// 全局超时配置
const client = createHttpClient({ timeout: 5000 });

错误处理

import { http, HttpError } from '@lytjs/common-http';

try {
  const response = await http.get('/api/users');
} catch (err) {
  if (err instanceof HttpError) {
    console.error('HTTP 错误:', err.status, err.message);
    if (err.response) {
      console.error('响应数据:', err.response.data);
    }
  } else {
    console.error('其他错误:', err);
  }
}

完整示例

import { createHttpClient, getJson, postJson, HttpError } from '@lytjs/common-http';

// 创建 API 客户端
const api = createHttpClient({
  baseURL: 'https://api.example.com',
  headers: {
    'Content-Type': 'application/json',
  },
});

// 添加身份验证拦截器
api.use({
  request(config) {
    const token = localStorage.getItem('token');
    if (token) {
      config.headers['Authorization'] = `Bearer ${token}`;
    }
    return config;
  },
  error(err) {
    if (err instanceof HttpError && err.status === 401) {
      // 处理未授权
      window.location.href = '/login';
    }
    throw err;
  },
});

// 使用 API 客户端
async function fetchUsers() {
  try {
    const users = await api.get('/users', {
      params: {
        status: 'active',
        page: 1,
      },
    });
    return users.data;
  } catch (err) {
    console.error('获取用户失败', err);
  }
}

// 使用便捷方法
async function createUser(data: any) {
  try {
    const user = await postJson('/users', data, {
      baseURL: 'https://api.example.com',
    });
    return user;
  } catch (err) {
    console.error('创建用户失败', err);
  }
}
