How to use query parameters in Nest.js?

You can use the @Req decorator, and use param object, see :

@Get()
  findAll(
    @Req() req: Request
  ): Promise<any[]> {
    console.log(req.query);
    // another code ....
  }

If you have you parameter as part or url: /articles/${articleId}/details, you wold use @Param

@Get('/articles/:ARTICLE_ID/details')
async getDetails(
    @Param('ARTICLE_ID') articleId: string
)

IF you want to provide query params /article/findByFilter/bug?google=1&baidu=2, you could use

@Get('/article/findByFilter/bug?')
async find(
    @Query('google') google: number,
    @Query('baidu') baidu: number,
)

we can use @Req()

@Get(':framework')
getData(@Req() request: Request): Object {
    return {...request.params, ...request.query};
}

/nest?version=7

{
    "framework": "nest",
    "version": "7"
}

Query parameters

You have to remove :params for it to work as expected:

@Get('findByFilter')
async findByFilter(@Query() query): Promise<Article[]> {
  // ...
}

Path parameters

The :param syntax is for path parameters and matches any string on a path:

@Get('products/:id')
getProduct(@Param('id') id) {

matches the routes

localhost:3000/products/1
localhost:3000/products/2abc
// ...

Route wildcards

To match multiple endpoints to the same method you can use route wildcards:

@Get('other|te*st')

will match

localhost:3000/other
localhost:3000/test
localhost:3000/te123st
// ...
