YaaS Bites Overview

The YaaS Bites enable software developers to go from zero-to-YaaS in a couple of days. They are small, focused, incremental coding exercises. Each bite has code, guidelines, and screencasts to ensure your initial journey into YaaS is successful and productive.

YaaS Bites makes learning YaaS fast and fun. Explore and learn with small, incremental coding exercises that contain essential information about coding in YaaS. The bites assume only that you know Java and some Spring, and take you quickly into working productively with YaaS.

1. If you are brand new to YaaS, read Why YaaS to explore the key business needs that YaaS fulfills, and the enormous potential it unleashes to developers.
2. Read YaaS Bites First Steps to learn how to make secure calls to YaaS services.
3. Work through YaaS Bites Essentials, to gain a firm grounding in YaaS development.
4. Finally work through YaaS Bites Sequel if you would like to explore coding beyond Java.

Keep in mind that while YaaS Bites focus on JVM languages, you can code YaaS solutions in any language you like. Your imagination and knowledge alone are the only limits.

Prerequisites

To follow YaaS Bites, you need:

• Maven 3.0
• Git to clone the examples
• Java 8 JDK to write and compile the example code, available at Oracle JDK or OpenJDK
• Eclipse IDE or a similar development environment
• These bites are aimed at developers who, we assume are working with large screens. The layout of the bites will be suboptimal on small displays.

Clone the code

After you have all of the tools listed in the Prerequisites section, clone the bites code.

1. Run git clone https://github.com/SAP/yaas-getting-started-yaasbites [Copy Me]
2. cd into the folder yaas-getting-started-yaasbites, which is referred to in the YaaS Bites as folder (yb).
