News Upcoming release - Calliope ----------- Hello people, I'm designing the new Iris version with the codename of "**Calliope**". Based on the **Greek goddesses** of ancient mythology, **Calliope** was one of the Muses, the muse of epic poetry, daughter of Zeus and Mnemosyne and the wisest of the Muses. The next, tactical, month release *should be published at the **1 May of 2017** *. I am making my bests to catch up this deadline, so I'm very busy these days. Sorry for being late to answer to your questions! **UPDATE: 6 May 2017** The release could be published at the first may of 2017 but it was postponed. The below tasks should be completed before publishing the new release: - The review, of the new release's specifications that I wrote, should be ready at the next couple of days. - The results from our beta testers may take a little more but it worths the waiting.

Buy me a cup of coffee?

Iris is free and open source but developing it has taken thousands of hours of my time and a large part of my sanity. If you feel this web framework useful to you, it would go a great way to ensuring that I can afford to take the time to continue to develop it.

I spend all my time in the construction of Iris, therefore I have no income value.

Feel free to send any amount through paypal

Please check your e-mail after your donation.

Thanks for your gratitude and finance help ♡

Third Party Middleware

Iris has its own middleware form of func(ctx *iris.Context) but it's also compatible with all net/http middleware forms using iris.ToHandler, i.e Negroni's middleware form of func(w http.ResponseWriter, r *http.Request, next http.HandlerFunc).

Here is a small list of Iris compatible middleware, I'm sure you can find more:

Middleware Author Description
binding Matt Holt Data binding from HTTP requests into structs
cloudwatch Colin Steele AWS cloudwatch metrics middleware
csp Awake Networks Content Security Policy (CSP) support
delay Jeff Martinez Add delays/latency to endpoints. Useful when testing effects of high latency
New Relic Go Agent Yadvendar Champawat Official New Relic Go Agent (currently in beta)
gorelic Jingwen Owen Ou New Relic agent for Go runtime
JWT Middleware Auth0 Middleware checks for a JWT on the Authorization header on incoming requests and decodes it
logrus Dan Buch Logrus-based logger
onthefly Alexander Rødseth Generate TinySVG, HTML and CSS on the fly
permissions2 Alexander Rødseth Cookies, users and permissions
prometheus Rene Zbinden Easily create metrics endpoint for the prometheus instrumentation tool
render Cory Jacobsen Render JSON, XML and HTML templates
RestGate Prasanga Siripala Secure authentication for REST API endpoints
secure Cory Jacobsen Middleware that implements a few quick security wins
stats Florent Messa Store information about your web application (response time, etc.)
VanGoH Taylor Wrobel Configurable AWS-Style HMAC authentication middleware
xrequestid Andrea Franz Middleware that assigns a random X-Request-Id header to each request
digits Bilal Amarni Middleware that handles Twitter Digits authentication

Feel free to put up a PR your middleware!

Testing

The httptest package is a simple Iris helper for the httpexpect, a new library for End-to-end HTTP and REST API testing for Go.

You can find tests by navigating to the source code, i.e:

A simple test is located to ./_examples/advanced/httptest/main_test.go

Philosophy

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. Keep note that, today, iris is faster than nginx itself.

Iris does not force you to use any specific ORM or template engine. Iris is routerless which means you can adapt any router you like, httprouter is the fastest, gorillamux has more features. With support for the most used template engines (5), you can quickly craft the perfect application.
