Before getting started


As we are going to compile the library from source code, we will need the source code of OpenLayers 3 for this chapter. You can find the source code of OpenLayers 3.11.1 in the src folder of the code appendix. Alternatively, you can download the source of the most recent version from the OpenLayers 3 GitHub repository at https://github.com/openlayers/ol3/releases. For the compiling, we will use Google's Closure Compiler, which is bundled with OpenLayers 3. On the top of this, the library offers convenience tools that are tailored for this specific library. As these tools are JavaScript files, we have to use a desktop JavaScript interpreter to use them. For this task, we will install Node JS, which is based on Google Chrome's JavaScript engine (V8).
