OpenFaaS is a serverless platform that provides an API gateway for deploying, managing, and invoking functions. The gateway handles HTTP routing to functions, collects and exposes Prometheus metrics, implements autoscaling based on invocation rates, includes a built-in AngularJS UI for function management, and supports alerting via integrations like Slack. It uses a plugin architecture for function providers (e.g., Kubernetes, Docker Swarm) via the faas-provider interface, allowing the core to remain decoupled from the underlying runtime. The system processes synchronous function invocations through a reverse proxy and asynchronous invocations via NATS queues.
The LLM identified 3 files worth highlighting for reuse:
Implements a reusable middleware that injects Basic Auth headers into outgoing requests. It depends only on standard library and an external auth package, demonstrating clean separation of concerns and dependency injection for cross-cutting concerns in HTTP servers.
A lightweight middleware that sets a configurable service name header on HTTP requests. With zero internal dependencies beyond the standard library, it exemplifies a highly extractable pattern for request enrichment in any Go HTTP service.
Provides a self-contained retry mechanism with exponential backoff and jitter. Depending only on the time package, it can be dropped into any Go project to handle transient failures, showcasing a well-encapsulated resilience pattern.
