How do I pass parameters from angular into my nodejs API?

Question

I want to pass the id from Angular in to my "/rating" HTTP-Endpoint, with the following call:

apiUpdateRating(id){
        return this.http.get('http://localhost:8080/rating', {
            params:id
        });
    }

But if console.log my "req.params" in my NodeJs API, I see that it is empty:

app.get('/rating',function(req,res){
    res.send('RParam: '+req.params);
});

Could anyone tell me where my mistake is? I think I do not pass the id properly in the URL, but don't know how to do it properly.

Try this:

  apiUpdateRating(id: number | string) {
    return this.http.get('http://localhost:8080/rating', {
      params: { id: id },
    });
  }

You need to specify both the key and value of a parameter. params is an object containing these key-value pairs.
