How to use query parameters in Nest.js?

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
// ...
