How to use query parameters in Nest.js?

javascript node.js typescript express nestjs

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

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

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

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

@Get('other|te*st')

will match

localhost:3000/otherlocalhost:3000/testlocalhost:3000/te123st// ...

javascript node.js typescript express nestjs

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,)

javascript node.js typescript express nestjs

we can use @Req()

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

/nest?version=7

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