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 🙏

@ureq/business

v0.0.3

Published

Universal request library business logic

Readme

@ureq/business

业务抽象层,提供 Hash 和 Cache 服务的接口定义和默认实现。

安装

npm install @ureq/business
# 或
pnpm add @ureq/business

注意:通常作为 @ureq/core 的依赖自动安装,无需单独安装

功能

HashService

提供请求哈希生成功能,用于请求去重和缓存键生成。

import { DefaultHashService } from '@ureq/business';

const hashService = new DefaultHashService();

// 生成请求哈希
const hash = hashService.generateRequestHash(
  'GET',
  '/api/users',
  null,
  { params: { page: 1 } }
);

// 生成字符串哈希
const strHash = hashService.hashString('some-string');

CacheStore

提供缓存存储的接口定义。

interface CacheStore {
  get<T>(key: string): Promise<T | null>;
  set<T>(key: string, value: T, ttl: number): Promise<void>;
  delete(key: string): Promise<void>;
  clear(): Promise<void>;
}

接口

HashService

interface HashService {
  generateRequestHash(
    method: string,
    url: string,
    data?: any,
    options?: RequestOptions
  ): string;
  
  hashString(str: string): string;
}

CacheStore

interface CacheStore {
  get<T>(key: string): Promise<T | null>;
  set<T>(key: string, value: T, ttl: number): Promise<void>;
  delete(key: string): Promise<void>;
  clear(): Promise<void>;
}

自定义实现

自定义 HashService

import { HashService } from '@ureq/business';

class MyHashService implements HashService {
  generateRequestHash(method: string, url: string, data?: any, options?: any): string {
    // 自定义哈希生成逻辑
    return `${method}:${url}`;
  }
  
  hashString(str: string): string {
    // 自定义字符串哈希
    return btoa(str);
  }
}

自定义 CacheStore

import { CacheStore } from '@ureq/business';

class MyCache implements CacheStore {
  async get<T>(key: string): Promise<T | null> {
    // 实现获取逻辑
  }
  
  async set<T>(key: string, value: T, ttl: number): Promise<void> {
    // 实现存储逻辑
  }
  
  async delete(key: string): Promise<void> {
    // 实现删除逻辑
  }
  
  async clear(): Promise<void> {
    // 实现清空逻辑
  }
}
