What is SpecSync?

SpecSync is a VS Code extension that automatically detects inconsistencies between your API documentation (Spec files) and code implementation.

Example:

<!-- login.spec.md -->
### Request
- username: string (6-20 characters)
- password: string (required)

// login.ts
interface LoginRequest {
    username: string;
    // ❌ Missing 'password' field - SpecSync will warn you!
}

Why SpecSync?

• 📉 55% of developers struggle with outdated API documentation (Postman 2025)
• ⏱️ Hours wasted debugging integration failures
• 🐛 Production bugs caused by docs not matching code

✨ Features

🚀 Quick Start

Install

Search "SpecSync" in VS Code Extensions panel and install logi-cmd.specsync.

Or via command line:

code --install-extension logi-cmd.specsync

Write Your First Spec

Create login.spec.md:

---
title: Login API
version: 1.0.0
---

## API: POST /api/login

### Request
- username: string (6-20 characters)
- password: string (8-32 characters, must contain letters and numbers)

### Response
- token: string
- expiresIn: number

### Business Rules
1. Username cannot be empty
2. Password must contain both letters and numbers

Implement Your Code

Create login.ts:

interface LoginRequest {
    username: string;
    password: string;
}

// SpecSync will detect if this doesn't match the spec
async function login(request: LoginRequest): Promise<{token: string}> {
    // Your implementation
}

SpecSync 是什么？

SpecSync 是一个 VS Code 扩展，自动检测 API 文档（Spec 文件）与代码实现之间的不一致。

示例：

<!-- login.spec.md -->
### 请求
- username: string (6-20 字符)
- password: string (必填)

// login.ts
interface LoginRequest {
    username: string;
    // ❌ 缺少 'password' 字段 - SpecSync 会提醒你！
}

为什么选择 SpecSync？

• 📉 55% 的开发者 苦于 API 文档过时 (Postman 2025)
• ⏱️ 数小时浪费在调试集成失败上
• 🐛 文档与代码不符导致的生产 bug

✨ 功能特性

🚀 快速开始

安装

在 VS Code 扩展面板中搜索 "SpecSync"，安装 logi-cmd.specsync。

或通过命令行：

code --install-extension logi-cmd.specsync

编写第一个 Spec

创建 login.spec.md：

---
title: 登录 API
version: 1.0.0

2. 密码必须包含字母和数字

实现代码

创建 login.ts：

interface LoginRequest {
    username: string;
    password: string;
}

// SpecSync 会检测是否与 spec 匹配
async function login(request: LoginRequest): Promise<{token: string}> {
    // 你的实现
}
