Hapi.dev

Hapi.dev is the home of the hapi open-source Node.js web framework, originally created by Eran Hammer at Walmart Labs to handle massive Black Friday-scale traffic. The framework is designed for building enterprise-grade, secure, and scalable server-side applications and APIs. Unlike middleware-based frameworks, hapi uses a rich plugin system, a structured request lifecycle, and enforces strong guarantees around routing, namespace protection, and extension ordering — making it safe for large distributed teams. Hapi is the only leading Node.js framework with zero external code dependencies, and requires 100% code coverage across all dependencies. The project was later managed by Sideway, Inc. after departing from Walmart Labs. Hapi is trusted in production by organizations including Brave and EBSCO requiring high-reliability backend infrastructure.
