In plain English

hapi is a framework for building applications, published under the package name @hapi/hapi. The README's tagline calls it the simple, secure framework developers trust, and the GitHub topics list places it in the Node.js world for HTTP and web application work. Beyond that one-line pitch, the README itself does not describe what hapi does in detail. It says the framework lets people build scalable applications with minimal overhead and full out-of-the-box functionality, with the slogan your code, your way. The README is mostly a directory of links. It points readers at the hapi.dev developer portal, which it describes as the place to go for tutorials, documentation, and support. Other useful resources listed include the main documentation and API reference, a version status page that covers builds, dependencies, supported Node.js versions, licenses, and end-of-life dates, a changelog, project policies, and a support page. The README also names the Technical Steering Committee. The listed members are Devin Ivy, Lloyd Benson, Nathan LaFreniere, Wyatt Lyon Preul, Nicolas Morel, and Jonathan Samines.
