Magento GraphQL

Learn how to use, but more importantly extend the GraphQL API of Magento

With the GraphQL API that Magento 2.3 introduced, it becomes possible to create your own headless frontend and detach yourself from the Magento monolith: Adobe PWA Studio, GraphCommerce and Vue Storefront 2 are living proof that this works. This course gives you all hands-on to extend upon the GraphQL API properly.

These are the options we give you:

At your place or ours?

Everyone learns at her/his own pace. We provide both in-house training and public training throughout Europe - whatever suits your team best. When 3 or more developers are attending, a custom training is often more economical. Contact us for more details.

You'll get courseware

Every workshop is accompanied with official Yireo coursematerial. Attendees are sent a digital version of this material after the training. It contains slides, comments and references. Additionally, our GitHub repos contain numerous more code samples.

Online classrooms

Online trainings are also our training: Via Zoom or Google Hangout sessions, our teacher is able to connect with your team. The benefit here is that the team is able to connect from various places itself as well, timeframes are more flexible. Afterwards, a video recording will be shared with all attendees for reference.

On-demand self-paced training

This training is also available as an On-Demand training: Via numerous video lessons, including accompanying student notes (equalling a book on their own), you'll learn about the topics in your own pace. And when you bump into questions, you can fall back to the teachers guidance.

Frequently Asked Questions

There is a minimum number of attendees listed. What does this mean?

The training is only held when there is a number of attendees. This number is usually 4 but sometimes we bring this down to 2 or 3. This minimum number simply means that if a class is not "full", either you get a refund or your ticket is transferred to another date.

Jisse Reitsma

The teacher: Jisse Reitsma

Thus it came to be

When Jisse started with Magento, he already had years of experience programming in Joomla (back in the days when Joomla was actually the #1 CMS - believe it or not). Back then, open source cart solutions were lacking and Magento 1.0 brought a lot of hope.

Quickly Jisse dived into the new architecture: In 2009, he built his first extensions, among which the fundaments of a bridge between Joomla and Magento (MageBridge) and various project-specific extensions (among which payment providers and custom MVC/EAV modules).

A relieve

Over the years, he experienced what most Magento developers experienced with M1: A lot of power, but also frustration. After a couple of years, it no longer was cutting-edge and it barely adopted new developer standards. When the new Magento 2.0 alpha 1 came out, Jisse started playing with it. And he was relieved to see modern tools in its architecture: Composer, PHP namespacing, testability, CLI-driven management, proper design patterns.

Again, after building some modules and dummy projects, the first Magento 2 developer training was given in January 2017 (two months after the official release) and numerous M2 trainings have followed for both backend developers, frontend developers and devops.

Frontend sagas

Currently, with Magento 2 being several years old now, the fuzz is no longer about its backend architecture: It is the frontend that matters. Jisse has given numerous frontend development trainings, where people complain about LESS (and not SASS) being used, loading times to be slow (while in fact M2 allows for enough tuning to make it bloody fast), an archaic combo of Knockout/RequireJS (while they both serve their purpose in regards to backwards compatibility).

PWA is the new keyword. Jisse has dived into React, Redux & service workers in combination with GraphQL and NodeJS tools. He is currently working in various initiatives to help developers embrace the new frontend stack (ExtDN, Vue Storefront, DEITY). Also, he has added Docker and Kubernetes to his vocabulary.

As of yet, it is fair to say that Magento holds little surprises for Jisse. He is your guy to train you or your developers properly in both backend and frontend technology.
