How to cancel requests

[zuhair-naqvi]

I'm implementing a query buffer to solve https://github.com/nodkz/react-relay-network-layer/issues/16

I'm able to construct a batch query object after all individual queries have been added to the queue and I only want to execute the final, batch-query and cancel all other requests.

Does react-relay-network-layer support this?

  // example of the custom inline middleware
  next => req => {
    return next(req);
  }

If you don't want pass request to internal fetch function, do not call next function. But you should return some promise.

  next => req => {
    const resultWithPayloadOrError = promiseThatProceedReqViaBuffer(req);
    return resultWithPayloadOrError;
  }

In promiseThatProceedReqViaBuffer:

requestList = [];
requestList.push(req.relayReqObj);

// after some tiny period of time, when you collect requests
queriesBatch(relayRequestList, fetchWithMiddleware)

Internally queriesBatch resolves/rejects all relay queries. But ideally somehow needs to pass resulting promise back to middleware (resultWithPayloadOrError).
