The Iris philosophy is to provide robust tooling for HTTP, making it a great solution for single page applications, web sites, hybrids, or public HTTP APIs.

Iris does not force you to use any specific ORM or template engine. With support for the most used template engines, you can quickly craft the perfect application.

This Benchmark suite aims to compare the whole HTTP request processing between Go web frameworks.

Iris suggests you to use this new suite to test your API. Httpexpect supports fasthttp & Iris after recommandation. Its author is very active so I believe its a promising library. You can view examples here and here.

Current: v3.0.0-rc.2

for the next release 'v3'

• Dynamic/Wildcard subdomains.
• Create server & client side (js) library for .on('event', func action(...)) / .emit('event')... (like socket.io but supports only websocket).
• Find and provide support for the most stable template engine and be able to change it via the configuration, keep html/templates support.
• Extend, test and publish to the public the Iris' cmd.
• Route naming and html url func, requested here.
