You will need to bring your own notebook to the workshop (with the operating system of your choice).
Please download Node.js for your operating system and install it in advance of the workshop, it will be required for building the application.
A satisfying text editor will be enough for editing the source code. We recommend using SublimeText for that - you can use its free trial version without restrictions as long as you want. If you want to install a more complex IDE, you can download and install WebStorm.
During the workshop you will require an E-Mail address to register for a cloud service. If you don't feel comfortable using your own one, please create a new one for this purpose in advance (e.g. a Google Mail address).
