gRPC-gateway as a KrakenD plugin

by Daniel López · Jun 9, 2019

The gRPC protocol is becoming trendy in the era of microservices. Its compactness and backward-compatibility make it very attractive. However, it requires custom code to work with it. In this article, we’ll show you how to get all the benefits from the gRPC protocol and the gRPC-gateway without coding any business logic to use your gRPC services as regular backends. Moreover, avoiding the extra network hop! Continue reading →

Doing housekeeping on your KrakenD configuration file

by Albert Lombarte · May 17, 2019

Starting your krakend.json configuration from scratch and writing every attribute in a blank editor might be a difficult and time consuming task, and that’s why we have the KrakenDesigner. KrakenDesigner is an aid tool to generate KrakenD configurations for the uninitiated audience. It produces a verbose output of the configuration file and explicitly writes unneeded attributes to let you see that a specific configuration option exists. These attributes I am mentioning are not necessary because they contain default values and the server is not going to alter its behavior. Continue reading →

by Albert Lombarte · Apr 7, 2019

It’s been only one month since we released KrakenD 0.8, and although we have been releasing new versions approximately every 3 months, we have very interesting features that can’t wait! KrakenD 0.9 comes with a series of very demanded features. Let’s get started! Integration with AMQP The AMQP integration allows you to send and receive messages to and from a queue through the KrakenD API Gateway. This feature enables the gateway to become in both a subscriber and a consumer of messages for asynchronous processing and opens the doors to very different implementations we were seeing.

How we run KrakenD on Javascript with WebAssembly

by Daniel Lopez · Dec 9, 2018

KrakenD is an API Gateway written in Go that uses a single configuration file to define its whole behavior. As the configuration file might be complicated, the KrakenDesigner is a javascript-based user interface to edit this file, and we were missing the capability of reproducing directly on javascript the existing gateway pipes so that users could run manual tests over the editing configuration. In this post, we are going to explain how we included KrakenD framework components in a . Continue reading →

KrakenD 0.7 released

The most relevant features for the 0.7 release are increased metrics and tracing options, and functionality that has been requested by many, the sequential proxy merger.

Reloading the Krakend configuration with Reflex and Docker

by Daniel Ortiz · Jun 22, 2018

A recurrent question when we go around is if KrakenD configuration can be hot-reloaded, this is changing endpoints, backends, or any other configuration of the gateway while it’s running. The short answer is: No, you can’t. You must restart the server. And although we might have something to alleviate this, let us explain first why we don’t support such a feature: Performance: This is the #1 reason, and strong enough. Continue reading →
