Feature request: More configuration options

[alexander-svendsen]

It is possible to configure this ourselves through the middleware api, but it would be more epic if the library had native support for these things:

const mock = FetchMock.configure({
  enableFallback: boolean,
  delay: number,         // each request is delayed by ms
  failureRate: number // unsure about this one, mabye % of request that fails
  
});

Hmm maybe add some labels to this project, so we can mark the things more correctly ?

I like keeping the number of options as low as possible.
But adding helper-functions to compose middlewares could be done.

E.g

const mock = FetchMock.configure({
  enableFallback: boolean,
  middleware: combine(
    delayMiddleware(1000),
    failurereateMiddleware(0.1),
    loggingMiddleware
  )
});

Or

const mock = FetchMock.configure({
  enableFallback: boolean,
  middleware: [
    delayMiddleware(1000),
    failurereateMiddleware(0.1),
    loggingMiddleware
  ]
});

Solved by #3
Solution ended up being:

const delayedErrorMock = FetchMock.configure({
  middleware: MiddlewareUtils.combine(
    MiddlewareUtils.delayMiddleware(200),
    MiddlewareUtils.failurerateMiddleware(0.2)
  )
});

Ofc the MiddlewareUtils. prefix can be removed using import {combine, delayMiddleware, failurerateMiddleware} from '...'
