Let's recap

• We can build stuff that makes Bosses happy
• We are freaking FAST
• Fundamentals are there
  • templating
  • static files
  • database operations

Let's recap

• going further it gets scarce
• we are not rails, yet – higher abstractions are still very much missing:
  • little abstractions for classic problems
  • little ORMs
• No framework on HTTP/2
• No (stable) framework for Async I/O:
  • github.com/sappworks/sapper

Where to go from here?

• go through this (and its alternative) implementation
• Follow AreWeWebYet.org
• nickel.rs has great docs
• clippy.bashy.io/docs
  • iron app
  • annotated source code
• JWT Auth with Nickel blog post by auth0.com
