8. HTTP Clients and Servers

Coming soon

This chapter is an outline. The full draft ships in a follow-up PR.

What this chapter will cover

You met the HTTP client in Chapter 2. This chapter covers it properly, alongside the server that serves requests from the other side.

Concepts introduced:

• Sync vs. async clients: when to use each, and why most code should start with sync.
• Configuring the client: timeouts, retry, rate limiting, connection pooling.
• The REST server: defining endpoints, binding them to a Design, and running them.
• The Router: composing endpoints into a larger service, including sub-routers.
• Server-sent events and streaming responses.
• Interop: how the client behaves identically on JVM, Scala.js, and Scala Native.
