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 →

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 →

Website development as a sysadmin

by Daniel Ortiz · May 10, 2018

As a systems administrator for the past 15 years, I’m not very used to web development as this kind of work has been usually done by other colleagues in every company I’ve worked for. I wanted to create a web application myself using an external API, as an exercise to go out my comfort zone. Some time ago I found that Marvel Comics has a REST API where you can get a lot of information about comics, characters, authors and other interesting information. Continue reading →

Edge computing - A story of buses, raspberries, IoT and API gateways

by Albert Lombarte · May 1, 2018

The IoT industry has been running for some years now adding millions of devices into the network. The range of devices and capabilities is very wide and heterogeneous, from small devices powered with a 9-volt battery to track the location of freight shippings traveling the oceans (using platforms like Sigfox) to permanently plugged devices with more powerful computing like a Raspberry Pi where computation cycles are not a problem.

How to work with Golang plugins and KrakenD

by Daniel López · Apr 12, 2018

The release of golang 1.8 more than a year ago opened the door to loading dynamic linked components in run time, and we were keen to find out if we could include this great feature in our KrakenD toolbox. We’d like to share our experience and details on how we enhanced our products to support golang plugins. Why would anyone use plugins in Go? The plugin concept is widely known and supported in several programming languages and environments. Continue reading →
