// Package server provides a lifecycle-aware HTTP server for Einherjar services.
|
||
|
|
//
|
||
|
|
// [Server] embeds both [lifecycle.Component] and [chi.Router], so it plugs
|
||
|
|
// directly into [launcher.New] and exposes the full chi routing API.
|
||
|
|
//
|
||
|
|
// For the happy path use [web.New], which pre-wires the recommended middleware
|
||
|
|
// stack. Use this package directly when you need explicit control over
|
||
|
|
// middleware order, a custom request-ID generator, or any other deviation from
|
||
|
|
// the defaults.
|
||
|
|
//
|
||
|
|
// # Basic usage
|
||
|
|
//
|
||
|
|
// srv := server.New(logger, server.Config{Port: 8080},
|
||
|
|
// server.WithMiddleware(
|
||
|
|
// mw.Recover(),
|
||
|
|
// mw.RequestID(myIDGenerator),
|
||
|
|
// mw.RequestLogger(logger),
|
||
|
|
// mw.CORS([]string{"https://example.com"}),
|
||
|
|
// ),
|
||
|
|
// )
|
||
|
|
//
|
||
|
|
// srv.Get("/health", health.NewHandler(logger, db))
|
||
|
|
//
|
||
|
|
// lc := launcher.New(logger)
|
||
|
|
// lc.Append(srv)
|
||
|
|
// lc.BeforeStart(func() error {
|
||
|
|
// srv.Mount("/v1", apiRouter)
|
||
|
|
// return nil
|
||
|
|
// })
|
||
|
|
// if err := lc.Run(); err != nil {
|
||
|
|
// logger.Error("launcher failed", err)
|
||
|
|
// os.Exit(1)
|
||
|
|
// }
|
||
|
|
//
|
||
|
|
// # Lifecycle
|
||
|
|
//
|
||
|
|
// [Server.OnInit] applies registered middleware to the router.
|
||
|
|
// [Server.OnStart] binds the TCP listener synchronously — a port conflict
|
||
|
|
// surfaces immediately rather than silently dropping the server. Requests
|
||
|
|
// are served in a background goroutine.
|
||
|
|
// [Server.OnStop] performs a graceful shutdown within [Config.ShutdownTimeout].
