Add support for React Native, remove and replace isomorphic-fetch

[Connorelsea]

Hello, I really like this library and use it quite frequently, but currently, it does not work with React Native.

This malfunction is due to redux-api-middleware's dependency on isomorphic-fetch, which has opted to not support React Native users. Despite Github implementing a similar fix on their equivalent library, isomorphic-fetch has chosen not to.

Due to this, some other projects have switched from isomorphic-fetch to fetch-everywhere in order to retain the same functionality while also supporting React Native. fetch-everywhere is an alternative library built using the same dependencies as isomorphic-fetch, but it includes support for React Native.

Would you consider switching fetch libraries in order to support React Native?

I am not faulting the maintainer of isomorphic-fetch, as I am fully aware people have lives outside of open source, but it is seemingly unmaintained. As of right now, fetch-everywhere seems like a better solution. Switching libraries will allow React Native users to use redux-api-middleware while also allowing users on other platforms to remain unaffected.

Examples of RN Fetch Issues Occuring

Here is one of the initial threads about this issue: matthew-andrews/isomorphic-fetch#63

Here is a continued thread about the issues that has yet to be merged. matthew-andrews/isomorphic-fetch#125

Here is a thread showing the maintainer's unwillingness to merge the fix, indicating a need for dependent libraries to switch if they wish to support React Native users: matthew-andrews/isomorphic-fetch#80

Libraries Switching from isomorphic-fetch to fetch-everywhere

Here is an example of another library removing isomorphic-fetch: redux-json-api/redux-json-api#91

Why not just use global fetch and remove the import statement all together? Then the consumer of the library is responsible for providing the correct implementation instead. Is this also a viable solution for React Native?

The next branch (which will lead to version 2) removes isomorphic-fetch in favor of the global fetch.

@agraboso We are expecting version 2.
When would you release it?

@mayyamak I am working on it, but don't have a lot of time to give to this project. There is a beta published to npm, based on the 'next' branch.

There are a few things left to do. You're more than welcome to contribute.
