Is there a way to inspect body/query params and respond with dynamic data? #454

Looking through the documentation I can't seem to find anything that would solve this issue so I figured I'd come here for some clarification. My use case is simple.


fetch('/artifact/:id', { params: { id: 1 } })

where 1 represents an Identifier but can change based on the interaction point, is there a way to setup a fetch mock that would be able to see that query param and respond with different data based on what that is set to.


const responseMap = {
  0: 'foo',
  1: 'bar',
  2: 'baz',

fetchMock.get('express:/artifact/:id', (url, options) => {
  return responseMap[]; 

yields: 'bar'

No there isn't. I would accept a PR to implement it, though I'm not sure what the API should look like. Overloading the options object with a params property feels ok I guess

You could implement something for yourself by using and applying it to url
