Set up RPC

[cinnamon-bun]

Right now sync happens over an HTTP REST API.

Generalize this using some RPC framework so it can happen over other transports too.

JSON-RPC is a good choice.

I'd like to throw in that earthstar-graphql is capable of doing this job, as it can be carried out over any transport.

[cinnamon-bun]

Hmm! Do you think GraphQL would work over a duplex stream like you get from hyperswarm?

[sgwilym]

Yes, so you can communicate bi-directionally with a GraphQL server using 'subscriptions' (here's an implementation which can be used with graphql-js, the package earthstar-graphql uses to define its schema: https://github.com/apollographql/graphql-subscriptions)

A lot of it is very new to me, but I think (?) this is right in principle.

I wrote mini-rpc for this purpose, now we need to hook it up in the sync and pub code.
