Make compatibility with reason-apollo optional

[fakenickels]

Currently we require reason-apollo to be installed along with reason-apollo-hooks to ease the transition, now we can drop it and make this optional

That would be very nice!
There are however some useful bindings that come with reason-apollo, particularly when it comes to working with cache. ApolloClient had WriteQuery and ReadQuery for this (which could actually benefit from some improvements..) Do you think we should create our own bindings for those?

[cem2ran]

I think it makes sense! Ideally we should split the bindings like react-apollo repo. common, components, hoc, hooks. Then there's react-apollo which has all of them.

[fakenickels]

That would be much better indeed @cem2ran, I think I can talk with @Gregoirevda about this. It'll scale much better

[Gregoirevda]

Sure, let's do that

[jfrolich]

With Apollo Client 3.0 deprecating the react-apollo package, and the reason-apollo bindings not really being updated, isn't it better to make this package self-containing? Include the read/write query code and some of the types in this package. This also means we can easily update to the Apollo Client 3.0 beta.

[fakenickels]

We could probably make this repo a monorepo and have a separated package for apollo-client
