Cardinal v0.0.2 — Middleware & Router Groups

Cardinal v0.0.2 — Middleware & Router Groups

This release makes Cardinal feel like a real framework: global middleware, per-route middleware, and router groups — all while keeping the core minimal.

✨ What’s new

• Middleware chain
  • r.Use(mwA, mwB) — global middlewares (Recover, Logging, RateLimit sample)
  • router.Middleware = func(Handler) Handler
• Per-route middleware
  • SHOWWith(path, h, ...mw) / INPUTWith(path, h, ...mw)
  • Order of execution: globals → route → handler
• Router groups
  • grp := r.Group("/secure", mw...) with optional nesting
  • Group middlewares apply after globals and before route middlewares
  • Execution order: globals → group(s) → route → handler
• Examples & docs
  • Updated examples showing HMAC/RateLimit as route/group middlewares
  • README sections for Middleware and Groups
• (Bonus) Emulator
  • Lightweight web emulator at /emu for interactive testing (if you’ve mounted it)
