All notable changes to this module will be documented in this file.

The format is based on Keep a Changelog, and this module adheres to Semantic Versioning.

0.9.1 - 2026-03-21

Fixed

• OnStop now returns nil immediately when s.srv == nil, preventing a nil pointer panic when the launcher calls cleanup on a server component whose OnStart was never reached (e.g. because an earlier component failed during startup).

0.9.0 - 2026-03-18

Added

• Logger interface — duck-typed; requires Info(msg string, args ...any) and Error(msg string, err error, args ...any); satisfied directly by logz.Logger and by any two-method struct, with no import of logz required
• Config struct — holds HTTP server configuration with env-tag support: Host (SERVER_HOST, default 0.0.0.0), Port (SERVER_PORT, default 8080), ReadTimeout (SERVER_READ_TIMEOUT, default 5s), WriteTimeout (SERVER_WRITE_TIMEOUT, default 10s), IdleTimeout (SERVER_IDLE_TIMEOUT, default 120s)
• Option functional option type for configuring the server at construction time
• WithMiddleware(mw ...func(http.Handler) http.Handler) Option — accumulates middleware applied to the root chi router during OnInit; order is preserved and caller-controlled; multiple calls to WithMiddleware append to the list
• HttpServerComponent interface — embeds both launcher.Component and chi.Router, giving callers the complete chi routing API (Get, Post, Route, Mount, Use, With, Group, etc.) on the same value that participates in the launcher lifecycle
• New(logger Logger, cfg Config, opts ...Option) HttpServerComponent — constructs the server component backed by chi.NewRouter(); no middleware is installed by default
• OnInit lifecycle method — applies all middleware registered via WithMiddleware to the root router; no-op if none were provided
• OnStart lifecycle method — constructs an http.Server with the configured timeouts and starts it in a background goroutine; logs the bind address on start and logs fatal errors if ListenAndServe exits unexpectedly
• OnStop lifecycle method — calls http.Server.Shutdown with a 10-second context timeout, giving in-flight requests up to 10 seconds to complete before the method returns

Design Notes

• HttpServerComponent embeds chi.Router directly in the interface rather than delegating through wrapper methods, so callers register routes and manage the lifecycle on the same value with no extra indirection
• No middleware is installed by default; the full middleware stack is composed explicitly via WithMiddleware at construction time, keeping the stack visible and ordering unambiguous in the application source
• chi was chosen as the underlying router because it uses stdlib http.Handler throughout, making it fully compatible with httpmw middleware and httputil handler adapters without any wrapper code at the boundary
