Yaya raunin yana aiki a cikin NestJS?

Question

Accepted Answer

**Routing** a cikin NestJS shine **jagorowar mai jagorantu**: kana taswira hanyoyin URL da hanyoyin HTTP zuwa hanyoyin sarari ta amfani da jagorowar. Gida na hanyar sau da `@Controller()` kuma takaici mai takaici + HTTP verb daga jagorowar hanyoyin kamar `@Get()` — haɗa don samar da gaida cikakke.

## Yaya aka tsara hanyoyi

```ts
@Controller("users")          // PREFIX: all routes start with /users
export class UsersController {
  @Get()                       // GET /users
  findAll() {}

@Get("active")               // GET /users/active
  findActive() {}

@Get(":id")                  // GET /users/:id (dynamic parameter)
  findOne(@Param("id") id: string) {}

@Post()                      // POST /users
  create(@Body() dto: CreateUserDto) {}

@Put(":id")                  // PUT /users/:id
  update(@Param("id") id: string, @Body() dto: UpdateUserDto) {}

@Delete(":id")               // DELETE /users/:id
  remove(@Param("id") id: string) {}
}
```

Gidajen sarari + jago hanyar jagorowar: `@Get(":id")` a cikin `@Controller("users")` → `GET /users/:id`. Kowane fi HTTP yana da nasu jagorowar (`@Get`, `@Post`, `@Put`, `@Patch`, `@Delete`).

## Jagorowan hanyar da jeweun bugi

```ts
@Get(":id")
example(
  @Param("id") id: string,        // path param: /users/123 → id = "123"
  @Query("sort") sort: string,    // query: /users?sort=name → sort = "name"
  @Query() allQuery: any,         // the whole query object
) {}
```

## Hanyoyin ja/wildcard da sub-hanyoyi

```ts
@Controller("users")
export class UsersController {
  @Get(":id/posts")              // GET /users/:id/posts (nested resource)
  getUserPosts(@Param("id") id: string) {}

@Get("search/*")               // wildcard matching
  search() {}
}
```

## Tsarin hanyar shi ma ya matuhi

```ts
@Get("active")    // ✅ specific route FIRST
findActive() {}
@Get(":id")        // dynamic route AFTER — else "active" would match :id
findOne() {}
```

Ya kamata a bayyana takaici (stashionari) hanyoyi kafin jagorantu (`:param`) daya, ko jagorantu hanyar zai iya karba su.

## Gida gida da sifofi

```ts
app.setGlobalPrefix("api/v1");   // all routes become /api/v1/...
// NestJS also supports API versioning (URI, header, media-type based)
```

Gida gida (alal misali `/api/v1`) yana aiki da kowane hanyar — gama da ka'ida API.

## Me ya sa haka makamashi

Raunin yana da mahimmanci — yana bayyana tsarin URL na API ka kuma haka ne kowane bugi ya kai jiya ma sarrafa da dama.

Sanin **jagorowar jagorantu** NestJS (gida `@Controller` haɗe da jagorowar hanyoyin `@Get`/`@Post`/etc. don samar da gaida cikakke, da `@Param`/`@Query` don cire bayani) shine makaranta makamashi kowane yau — haka ne kake aiki kowane gaba, da alamba ƙarfin yana ajiye raunin tsafi kuma karantabilu idan aka hade da jarrewa jarrewa.

Sanin bayani na aiki — haɗe jidaje da hanyoyi, aiki jagorowan hanyar da jeweun bugi, hanyoyi kawo allunan, mahimmancin **tsarin hanyar** (stashionari kafin jagorantu), da gida jidaje/sifofi don ka'idodi API — ya zama dole don gina saitin API a NestJS.

Raunin, jagorowar, da jagorowar sigogi tare sun samar da gida canji-jiyya na jagorantu, yana sa haka aiki, dole-dole sanin kowa NestJS mahada.
