Krakend HTTP Cache

A cached http client for the KrakenD framework

Using it

This package exposes two simple factories capable to create a instances of the proxy.HTTPClientFactory and the proxy.BackendFactory interfaces, respectively, embedding an in-memory-cached http client using the package github.com/gregjones/httpcache. The client will cache the responses honoring the defined Cache HTTP header.

import 	(
	"context"
	"net/http"
	"github.com/luraproject/lura/v2/config"
	"github.com/luraproject/lura/v2/proxy"
	"github.com/luraproject/lura/v2/transport/http/client"
	"github.com/krakendio/krakend-httpcache/v2"
)

requestExecutorFactory := func(cfg *config.Backend) proxy.HTTPRequestExecutor {
	clientFactory := httpcache.NewHTTPClient(cfg, client.NewHTTPClient)
	return func(ctx context.Context, req *http.Request) (*http.Response, error) {
		return clientFactory(ctx).Do(req.WithContext(ctx))
	}
}

You can create your own proxy.HTTPRequestExecutor and inject it into your BackendFactory
