Working with Route Parameters
Pyyhkäise näyttääksesi valikon
Route parameters allow you to pass dynamic values in the URL.
For example, instead of requesting all users, you can request a specific user by ID.
Define a route parameter like this:
import { Controller, Get, Param } from '@nestjs/common';
@Controller('users')
export class UsersController {
@Get(':id')
getUserById(@Param('id') id: string) {
return `User ID: ${id}`;
}
}
:id: defines a dynamic part of the URL;@Param('id'): extracts the value from the URL;id: is passed into the method.
When you open:
/users/5
The response will be:
User ID: 5
You can use route parameters whenever you need to work with specific data, such as users, products, or orders.
