Access Operation inside isTokenValidOrUndefined and handleFetch/handleError

When using this library we ran into issue of not being able to access Redux state or dispatch actions inside the TokenRefreshLink because Operation was not accessible inside of it. We had to tweek it a bit so that these functions would pass Operation object.

I believe this use case is quite common because if we store accessToken inside Redux and after refreshing it want to change the state, there’s no possible way to that without having access to context.

This requires minimal changes to the existing code though helps a lot, so it would be nice to have this functionality as part of this library.

export type HandleResponse = (operation: Operation, accessTokenField: string) => void;
export type HandleError = (operation: Operation, err: Error) => void;
export type IsTokenValidOrUndefined = (operation: Operation, ...args: any[]) => boolean;

if (!this.fetching) {
            this.fetching = true;
            this.fetchAccessToken()
                .then(this.handleResponse(operation, this.accessTokenField))
                .then(body => {
                    const token = this.extractToken(body);

                    if (!token) {
                        throw new Error('[Token Refresh Link]: Unable to retrieve new access token');
                    }
                    return token;
                })
                .then(payload => this.handleFetch(operation, payload))
                .catch(error => this.handleError(operation, error))
                .finally(() => {
                    this.fetching = false;
                    this.queue.consumeQueue();
                });
        }

Update* my configuration of Redux was incorrect - accessing the store directly instead of through operation does work as intended. Tonight, I will still put together a code sandbox to demo what I have.

Original message:

Right, but I can confirm that this setup isn’t working.

Seems the dispatch isn’t getting called correctly from here.

I might be able to put together an example on code sandbox to demo

I think I’ve already updated README. thanks)
