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 🙏

账户模型 (src/models/account/)

| 模块 | 说明 | |------|------| | account | 登录账号模型 | | user | 用户信息模型(含性别、启用状态枚举) | | session | 会话管理模型(含多种登录方式请求/响应) | | message | 消息模型 | | app | 应用配置模型(支持微信、企业微信、QQ、百度等应用类型) | | verificationCode | 验证码模型(图片、手机、邮件验证码) | | wx | 微信相关接口请求/响应模型 |

AI 模型 (src/models/ai/)

| 模块 | 说明 | |------|------| | message | AI 消息体接口定义 |

🛠 工具类 (Utils)

日志记录器 (src/utils/logger.ts)

基于 pino 的远程日志记录器,支持本地日志和远程日志同步发送。

import { RemotePinoLogger } from '@fefeding/common';

const logger = new RemotePinoLogger({
  remoteUrl: 'https://your-log-server.com/api/log',
  serviceName: 'my-service',
  logLevel: 'info',
  apiKey: 'your-api-key'
});

logger.info('操作成功', { userId: 123 });
logger.error('发生错误', { error: err.message });

HTTP 请求 (src/utils/axios.ts)

Axios 封装,支持直接传入请求模型对象。

import { requestApi, requestServer } from '@fefeding/common';

// 使用请求模型
const res = await requestApi(new LoginReq({ account, password }));

// 或直接使用 URL
const data = await requestApi('/api/user/info', { method: 'GET' });

API Token 生成 (src/utils/api.ts)

基于 MD5 的 API Token 生成工具。

import api from '@fefeding/common';

const token = api.createApiToken('your-access-key');
// 返回 { sign: '...', timestamp: '...' }

装饰器 (src/utils/decorator.ts)

提供 API 路由、权限校验等装饰器。

import decorators from '@fefeding/common';

// 标记 API 路由
@decorators.api({ url: '/api/user/save' })
export class SaveUserReq extends Request {
  data: User;
}

// 标记需要 Token 校验
@decorators.checkApiToken()
async saveUser() { ... }

// 标记需要登录态校验
@decorators.checkApiLogin()
async getUserInfo() { ... }

腾讯云 COS 操作 (src/utils/txCos.ts)

腾讯云对象存储操作封装。

import { createClient, uploadFile, getFile, getObjectUrl, checkExists } from '@fefeding/common';

const cos = createClient({
  SecretId: 'your-secret-id',
  SecretKey: 'your-secret-key'
});

// 上传文件
await uploadFile({
  Bucket: 'your-bucket',
  Region: 'ap-guangzhou',
  Key: 'file.txt',
  Body: Buffer.from('content')
}, cos);

// 获取文件预签名 URL
const url = await getObjectUrl({
  Bucket: 'your-bucket',
  Region: 'ap-guangzhou',
  Key: 'file.txt',
  Sign: true
}, cos);

// 检查文件是否存在
const exists = await checkExists({
  Bucket: 'your-bucket',
  Region: 'ap-guangzhou',
  Key: 'file.txt'
}, cos);

随机字符串生成 (src/utils/rand.ts)

import { randString, stringToNumber } from '@fefeding/common';

// 生成随机短码
const code = randString(123, 8); // 基于ID生成唯一短码

// 字符串转数字(用于哈希计算)
const num = stringToNumber('abc');
