This repository provides a way to share any minor handlers for ion web framework. You can view the built'n supported handlers by pressing here.

Installation

$ go get github.com/get-ion/middleware/...

Middleware is just a chain handlers which can be executed before or after the main handler, can transfer data between handlers and communicate with third-party libraries, they are just functions.

Middleware	Description	Example
jwt	Middleware checks for a JWT on the Authorization header on incoming requests and decodes it.	jwt/_example
cors	HTTP Access Control.	cors/_example
secure	Middleware that implements a few quick security wins.	secure/_example
tollbooth	Generic middleware to rate-limit HTTP requests.	tollbooth/_examples/limit-handler
cloudwatch	AWS cloudwatch metrics middleware.	cloudwatch/_example
new relic	Official New Relic Go Agent.	newrelic/_example
prometheus	Easily create metrics endpoint for the prometheus instrumentation tool	prometheus/_example

How can I register middleware?

To a single route

app := ion.New()
app.Get("/mypath", myMiddleware1, myMiddleware2, func(ctx context.Context){}, func(ctx context.Context){}, myMiddleware5,myMainHandlerLast)

To a party of routes or subdomain

myparty := app.Party("/myparty", myMiddleware1,func(ctx context.Context){},myMiddleware3)
{
	//....
}

To all routes

app.Use(func(ctx context.Context){}, myMiddleware2)

To global, all routes on all subdomains on all parties

app.UseGlobal(func(ctx context.Context){}, myMiddleware2)

Can I use standard net/http handler with ion?

Yes you can, just pass the Handler inside the ion.FromStd in order to be converted into context.Handler and register it as you saw before.

Convert handler which has the form of http.Handler/HandlerFunc

package main

import (
	"github.com/get-ion/ion"
	"github.com/get-ion/ion/context"
)

func main() {
	app := ion.New()

	sillyHTTPHandler := http.HandlerFunc(func(w http.ResponseWriter, r *http.Request){
	     println(r.RequestURI)
	})

	sillyConvertedToIon := ion.FromStd(sillyHTTPHandler)
	// FromStd can take (http.ResponseWriter, *http.Request, next http.Handler) too!
	app.Use(sillyConvertedToIon)

	app.Run(ion.Addr(":8080"))
}
