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 🙏

  • 🚀 高性能 - 基于 Bun 运行时,超快的启动和执行速度
  • 🔌 插件化架构 - 灵活的插件系统,轻松扩展功能

  • 📝 自动化表管理 - 基于 JSON 的表定义,自动同步数据库结构
  • 🔐 内置身份验证 - JWT 认证,角色权限管理
  • 📊 完整日志系统 - 结构化日志,敏感字段过滤

📦 快速开始

安装

# 创建新项目
mkdir my-api && cd my-api

# 安装 Befly
bun add befly

最简示例

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

// 配置从 configs/befly.*.json 扫描加载(见 packages/core/befly.config.ts)
const app = new Befly();
await app.start(Bun.env);

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/api";

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/app/user/hello

最小 smoke:在 api 模板项目新增接口并访问

  1. 新增文件:apis/user/hello.ts(上面示例可直接使用)
  2. 启动服务:bun run dev
  3. 访问:http://localhost:3000/api/app/user/hello

🔥 新版本特性(3.0)

TypeScript 全面支持

import type { ApiRoute } from "befly/types/api";
import type { BeflyContext } from "befly/types/befly";
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:

请参考:befly 的同步文档:packages/core/docs/reference/sync.mdsyncDb / syncAll 等同步流程说明)。

🗄️ 数据库配置(MySQL 8.0+)

统一使用环境变量配置(仅 MySQL 8.0+):

DB_HOST=127.0.0.1
DB_PORT=3306
DB_USER=root
DB_PASS=password
DB_NAME=my_database
