When you need to pretend you are a REST API, but you're really not

Vostok is a Rust-Based HTTP Transformation Layer To Seamlessly Convert REST Calls Into GraphQL Calls For Piecemeal API Migrations.

Need to implement some test servers for REST and for GraphQL. Need a Couple of Cases:

• Passthrough paths that are not overridden
• A direct transformation from REST<->GraphQL
• An advanced transformation from REST<->GraphQL which processes the data

We can set up a couple of REST endpoints:

• GET /api/v1/uuid returns a UUID
• GET /api/v1/me returns a JSON object { data: { username: "Ariel", ... } }

And a GraphQL schema:

type User {
  username: String!
}

Query {
  me: User!
  uuid: String!
}

TODO: Make the above setup a bit more advanced.

• hyper for managing HTTP requests
• routerify to manage routes in hyper
• anyhow for nice error handling
• log and fern for logging
• chrono for time handling
• hyper-rustls for handling HTTPS in hyper
• httpbin: A simple HTTP Request & Response Service. is very useful for testing
• cargo-watch for developing with cargo dev (install via cargo install cargo-watch)

Potentially:

• warp as a higher-level alternative to hyper
• warp-reverse-proxy is a warp filter for easy reverse proxying
• reqwest is a high-level HTTP client
