Viewing and debugging Java source code in the browser couldn't be easier with source maps. In this lesson Kyle discusses how GWT supports the source map standard, and how to use it in a modern browser.
- [Instructor] Recall in super dev mode…the GWT compiles the entire application into java script…which means it's not really possible…to use the convenient debugging tools…that are available in a modern IDE like Eclipse.…Instead, we must rely on the development tools…of the modern browser like Chrome…which come with baked in development tools…and are accessible via either right clicking…and clicking inspect or using the keyboard shortcut…of option command i.…Either way the development tools will open…and if we wanted to see the compressed…and compiled java script…that is actually behind this application…click the sources option and navigate to currency convertor…open up this no domain and then you can see…let me drag this window up…the compressed java script for the GWT application.…
So we could debug this code…but I don't know about you but this is far more complicated…and not human readable for me to debug.…It would be really great if we could see our java code,…the source code that's generating this java script…
In this course, learn how to build high-performance, browser-based apps using GWT. Kyle Gower-Winter introduces you to GWT, explaining the benefits of using this toolkit to build dynamic web pages. To help you practice what you learn, he shows how to build a simple foreign exchange rate application. Plus, Kyle covers managing AJAX events on the client, handling UI action events, debugging code, and more.
