manipulator route in Nest.js

Question

manipulator route in Nest.js

I have the following PATCH request:

http://localhost:3000/tasks/566-344334-3321/status

.

The handler for this request is written as:

@Patch('/:id/status')
updateTaskStatus() { // implementation here 
    return "got through";
}

I am struggling to grasp the workings of the stem part and how the appropriate handler is mapped to process the request.

For instance, in /566-344334-3321/status
The id section is /566-344334-3321 which is variable.
However, the fixed suffix /status must be precise.
Any deviation results in an error message: "error": "Not Found".

What explains this behavior?

Answer №1

To obtain the `id` parameter, utilize the `@Param` decorator to map the `:id` in your request to a typescript number.

Here is the correct way to implement the `updateTaskStatus` function as per the guidance provided in the NestJS documentation on Route Parameters

@Patch('/:id/status')
updateTaskStatus(@Param('id') id: number) { 
    return `Received ${id} successfully`;
}

If you intend to use `status` as a dynamic value similar to `id`, ensure to annotate your parameter with the same decorator

@Patch('/:id/:status')
updateTaskStatus(@Param('id') id: number, @Param('status') status: string) { 
    return `Received ${id} and ${status} successfully`;
}

The NestJS documentation is comprehensive and valuable, make sure to explore the documentation related to controllers
