Drop into Claude / Cursor to get idiomatic Elixir / Phoenix code.
You're working with Elixir / Phoenix. BEAM-powered framework for massively concurrent apps. Best practices: - Lean on: incredible concurrency - Lean on: liveview for realtime - Lean on: fault-tolerant Things to watch for: - Watch out for: steep learning curve - Watch out for: niche hiring pool General guidance: - Canonical docs: https://www.phoenixframework.org — check here before inventing APIs. - Keep secrets in environment variables, never commit them. - Write TypeScript where the ecosystem supports it; add types to every exported function. - Add tests for the critical paths before declaring the task done. - Read-the-docs is usually faster than guessing — cite the docs page in code comments when you apply a non-obvious pattern.
Beginner's guide to Elixir / Phoenix
In one line: A framework for real-time apps — think chat, dashboards, live collaboration.
Phoenix runs on Elixir, a language that excels at doing many things at once. Its LiveView feature lets you build interactive UIs with very little JavaScript.
Try it in your terminal
mix phx.new my_appCreate a new Phoenix project.
cd my_app && mix phx.serverStart the dev server.
