Echo middleware: Souin

This is a distributed HTTP cache module for Echo based on Souin cache.

Features

• RFC 7234 compliant HTTP Cache.
• Sets the Cache-Status HTTP Response Header
• REST API to purge the cache and list stored resources.
• Builtin support for distributed cache.
• Tag-based invalidation.

Example

There is the example about the Souin initialization.

import (
	"net/http"

	souin_echo "github.com/darkweak/souin/plugins/echo"
	"github.com/labstack/echo/v4"
)

func main(){

    // ...
	s := souin_echo.NewMiddleware(souin_echo.DevDefaultConfiguration)
	e.Use(s.Process)
    // ...

}

With that your application will be able to cache the responses if possible and returns at least the Cache-Status HTTP header with the different directives mentionned in the RFC specification.
You have to pass an Echo Configuration structure into the NewMiddleware method (you can use the DefaultConfiguration variable to have a built-in production ready configuration).
See the full detailled configuration names here.

You can find an example for a docker-compose stack inside the examples folder.
See the Souin configuration for the full configuration, and its associated development echo middleware
