Polydev
A Chrome DevTools extension for profiling web component lifecycle callbacks and Polymer databinding performance.
What is Polydev?
polydev is a Chrome DevTools extension designed to profile the performance of web components and Polymer applications. It tracks time spent in custom element lifecycle callbacks and Polymer databinding changes, displaying results as annotated spans in Chrome's timeline recording tool. The tool helps developers identify performance bottlenecks specific to web component architectures.
Frontend developers building applications with Polymer or vanilla custom elements who need to optimize performance and understand lifecycle callback timing.
It provides native DevTools integration for web component profiling, offering detailed, instance-level timing data that isn't available in standard performance tools. Developers choose polydev for its specialized focus on the web components ecosystem and its ability to visualize databinding performance.
