erlang-otp-behaviors

What problem does it solve?

OTP patterns solve the complexity of building reliable, concurrent Erlang applications by providing reusable building blocks for stateful processes, state machines, and fault-tolerant supervision trees.

Core Features & Use Cases

• Gen_server basics: client-server processes with managed state and robust callbacks.
• Gen_statem for state machines: explicit state transitions for protocol-heavy logic.
• Supervisors and trees: automatic recovery and fault tolerance across components.
• Practical examples: from simple counters to a cache with timeouts and dynamic supervision.

Quick Start

Set up an Erlang project that demonstrates gen_server, gen_statem, and a simple supervisor tree to illustrate OTP patterns.
