Third-Party Handlers

iris has its own middleware form of func(ctx context.Context) but it's also compatible with all net/http middleware forms. See here.

Here's a small list of useful third-party handlers:

Middleware Description
goth OAuth, OAuth2 authentication. Example
binding Data binding from HTTP requests into structs
csp Content Security Policy (CSP) support
delay Add delays/latency to endpoints. Useful when testing effects of high latency
onthefly Generate TinySVG, HTML and CSS on the fly
permissions2 Cookies, users and permissions
RestGate Secure authentication for REST API endpoints
stats Store information about your web application (response time, etc.)
VanGoH Configurable AWS-Style HMAC authentication middleware
xrequestid Middleware that assigns a random X-Request-Id header to each request
