What's happening?

Are you already familiar with GraphQL?

GraphQL is a new query language, launched by Facebook, that makes your data queries blazingly fast and stable. It’s also very predictable: ask for what you need and you'll get exactly that. Apps using GraphQL are fast and stable because they control the data they get, not the server. As well as that, it allows for many resources in a single request: cache data, realtime fetching, etc.

In this free and fun HackJam, you will choose your favourite Javascript weapon - React or Angular - and use GraphQL with it. At the end of the evening, you will have a global understanding of GraphQL, the power of it, and have probably developed a love for it too.


You will be given a broken app and will have to fix it by implementing GraphQL queries, mutations, and by using the language to write a schema. You will learn front-end queries and mutations, as well as back-end GraphQL schema in Node.JS - and there will be expert mentors happy to help you with that.

The event starts at 6.30pm with some yummy food and refreshing drinks, and then you'll hack the night away (or just until the end of the event). Please update your RSVP in time if you can't make it, in order to avoid any waste. Thanks ahead!

What's in it for me?

By fixing the application, you will understand how GraphQL works and will be able to:

- Write basic GraphQL queries
- Write advanced GraphQL queries
- Write mutations
- Write a schema in Node.JS with the right tools

On top of this exciting challenge, we will also be raffling one JetBrains licence. 

A few requirements:

- Bring your own computer, with Node and Git installed
- Have a good command of JavaScript

Look forward to hacking with you!
