Summary

The primary web server will be migrated to fastify from express. The graphql server will be migrated to graphql-yoga from apollo-server.

The graphql server will be decoupled from the fastify server to have seperation of concerns make it easier to swap out either the HTTP server(fastify) or the graphql server(graphql-yoga). All the dependencies required by the graphql resolvers at runtime will be provided to them using the graphql context and direct imports inside the resolver functions will be kept to a minimum.

It is of utmost importance that the HTTP layer does not bleed into the graphql layer to prevent tight coupling.

Please fix the conflicting files so we can merge

[xoldd]

@palisadoes actually this PR is incomplete, upon introspection I've found that the current code organization is really messy in the codebase, so I'm still trying to fix that. If it's a problem you can close this PR, I'll open a new one later on.

Thanks. Closing
