[Nest](https://github.com/nestjs/nest) framework TypeScript starter repository.

This is a server-side development template based on Nest.js

## Installation

```bash
$ npm install
```

## Running the app

```bash
# development
$ npm run start

# hot update
$ npm run start:hot

# watch mode
$ npm run start:dev

# production mode
$ npm run start:prod
```

```

## Support

Nest is an MIT-licensed open source project. It can grow thanks to the sponsors and support by the amazing backers. If you'd like to join them, please [read more here](https://docs.nestjs.com/support).

## Web框架

使用`Fastify`作为前端框架

```bash
# 安装对于nest的适配器@nestjs/platform-fastify
$ npm install @nestjs/platform-fastify
```

## 版本配置

```ts
// main.ts 启用配置
app.enableVersioning({
    type: VersioningType.URI,
});
```

在相关的请求使用`@Version('1')`装饰符设置版本

## 全局返回参数设置

`src/common/interceptors/transform.interceptor.ts`
```ts
import {
  Injectable,
  NestInterceptor,
  ExecutionContext,
  CallHandler,
} from '@nestjs/common';
import { Observable } from 'rxjs';
import { map } from 'rxjs/operators';

interface Response<T> {
  data: T;
}

@Injectable()
export class TransformInterceptor<T>
  implements NestInterceptor<T, Response<T>>
{
  intercept(
    context: ExecutionContext,
    next: CallHandler,
  ): Observable<Response<T>> {
    return next.handle().pipe(
      map((data) => ({
        data,
        status: 0,
        extra: {},
        message: 'success',
        success: true,
      })),
    );
  }
}
```

在`main.ts`中添加全局拦截处理`useGlobalInterceptors`
```ts
import { TransformInterceptor } from './common/interceptors/transform.interceptor';
// 统一响应体格式
app.useGlobalInterceptors(new TransformInterceptor());
```
