Google unveils DevTools extension for Angular Google unveils DevTools extension for Angular Angular DevTools is a new Chrome extension that provides debugging and profiling capabilities for Angular applications. Credit: Dreamstime Google has published Angular DevTools, a Chrome DevTools extension to inspect the structure and profile performance of applications built with the Angular framework. Developed in conjunction with tool builder Rangle.io, and introduced May 18, Angular DevTools is focused on visualisation of the component structure and understanding change detection execution. The extension is available in the Chrome Web Store. Similar to Rangle.io’s Augury debugging tool for Angular, Angular DevTools offers a component explorer to preview application structure and provides an overview of change detection cycles, helping to reveal performance bottlenecks and enable developers to deliver 60fps experiences. A profiler tab shows individual change detection cycles, what triggered them, and how much time Angular spent in them. Change detection cycles can be previewed in real time.
