yWorks Optimizer
The yWorks Optimizer obfuscates the public API of the yFiles module files and adapts the usages in your application code accordingly.
We highly recommend using the yWorks Optimizer as part of your production build in addition to a generic minifier/obfuscator. The yWorks Optimizer is precisely tailored to the structure of the yFiles library modules and therefore achieves an obfuscation and size reduction of the yFiles library. However, it does not generally minify/obfuscate your application.
At the time of writing, you are not required to obfuscate the yFiles library, though.
See @yworks/optimizer on npm for details about this tool.
See also the corresponding section of the Deployment chapter for use cases of the yWorks Optimizer that are demonstrated in the yFiles for HTML package.
App Generator
The App Generator is an ETL tool that lets you rapidly prototype yFiles for HTML applications with custom data, styling and graph layout.
With a few clicks you can configure a yFiles for HTML application and export it as plain JavaScript or for various target frameworks like React, Angular or Vue.js.
