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 🙏

📦 快速开始

安装

# 创建新项目
mkdir my-api && cd my-api

# 安装 Befly
bun add befly

# 初始化项目(即将支持)
bunx befly init

最简示例

// main.ts
import { Befly } from 'befly';

const app = new Befly({
    appName: 'My API',
    appPort: 3000
});

await app.start();

运行项目:

bun run main.ts

创建第一个接口

// apis/user/hello.ts
import type { ApiRoute } from 'befly/types/index';

export default {
    name: '问候接口',
    auth: false, // 公开接口
    fields: {},
    handler: async (befly, ctx) => {
        return {
            msg: 'Hello, Befly!',
            data: {
                timestamp: Date.now()
            }
        };
    }
} as ApiRoute;

访问:http://localhost:3000/api/user/hello

🔥 新版本特性(3.0)

TypeScript 全面支持

import type { ApiRoute, BeflyContext } from 'befly/types/index';
import type { User } from './types/models';

export default {
    name: '获取用户',
    auth: true,
    fields: {
        id: '用户ID|number|1|999999|null|1|null'
    },
    required: ['id'],
    handler: async (befly: BeflyContext, ctx) => {
        const { id } = ctx.body;

        // 类型安全的数据库查询
        const user = await befly.db.getOne<User>({
            table: 'user',
            where: { id }
        });

        return { msg: '查询成功', data: user };
    }
} as ApiRoute;

增强的数据库操作

// 查询单条
const user = await befly.db.getOne<User>({
    table: 'user',
    where: { id: 1 }
});

// 分页列表
const result = await befly.db.getList<Product>({
    table: 'product',
    where: { category: 'electronics' },
    page: 1,
    limit: 10,
    orderBy: ['createdAt#DESC']
});

// 插入数据
await befly.db.insData({
    table: 'user',
    data: {
        username: 'john',
        email: '[email protected]'
    }
});

// 更新数据
await befly.db.updData({
    table: 'user',
    where: { id: 1 },
    data: {
        nickname: 'John Doe'
    }
});

// 删除数据
await befly.db.delData({
    table: 'user',
    where: { id: 1 }
});

智能表定义

{
    "username": "用户名|string|3|50|null|1|^[a-zA-Z0-9_]+$",
    "email": "邮箱|string|5|100|null|1|^[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\\.[a-zA-Z]{2,}$",
    "age": "年龄|number|0|150|18|0|null",
    "tags": "标签|array_string|0|10|null|0|null",
    "bio": "简介|text|0|5000|null|0|null"
}

字段定义格式:"字段名|类型|最小值|最大值|默认值|是否索引|正则约束"

同步到数据库:

bun run scripts/syncDb.ts

🗄️ 数据库配置

统一使用环境变量配置,支持三种数据库:

# MySQL
DB_TYPE=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_USER=root
DB_PASS=password
DB_NAME=my_database

# PostgreSQL
DB_TYPE=postgresql
DB_HOST=localhost
DB_PORT=5432
DB_USER=postgres
DB_PASS=password
DB_NAME=my_database

# SQLite
DB_TYPE=sqlite
DB_NAME=/path/to/database.sqlite
# 或使用内存数据库
DB_NAME=:memory:

⚙️ 项目配置文件

Befly 使用 befly.config.ts 作为统一配置文件:

// befly.config.ts
export const beflyConfig = {
    appName: '我的应用',
    appPort: 3000,
    appHost: '0.0.0.0',

    // 数据库配置(优先使用环境变量)
    db: {
        type: 'mysql',
        host: '127.0.0.1',
        port: 3306,
        username: 'root',
        password: 'password',
        database: 'my_database'
    },

    // Redis 配置
    redis: {
        host: '127.0.0.1',
        port: 6379,
        prefix: 'befly:'
    },

    // CORS 跨域配置
    cors: {
        origin: ['http://localhost:5173'],
        methods: ['GET', 'POST', 'PUT', 'DELETE']
    },

    // Addon 插件配置
    addons: {
        admin: {
            email: { host: 'smtp.qq.com' }
        }
    }
};

数据库连接

框架会自动从 beflyConfig 获取配置并建立连接,无需手动传参:

import { Connect } from 'befly/lib/connect';

// 连接 SQL 数据库(配置自动从 beflyConfig.db 获取)
await Connect.connectSql();

// 连接 Redis(配置自动从 beflyConfig.redis 获取)
await Connect.connectRedis();

// 同时连接 SQL 和 Redis
await Connect.connect();

// 获取连接状态
const status = Connect.getStatus();
console.log(status.sql.connected); // true/false
console.log(status.redis.connected); // true/false

// 断开连接
await Connect.disconnect();

配置文件迁移指南

如果你的项目之前使用 app.config.ts,请按以下步骤迁移:

  1. 重命名文件app.config.tsbefly.config.ts
  2. 更新导出名configbeflyConfig
// 旧写法
export const config = { ... };

// 新写法
export const beflyConfig = { ... };
