Svelte DevTools is a browser DevTools extension for the open-source Svelte JavaScript framework. It allows you to gain deep insights and inspect the Svelte component hierarchies in the Developer Tools panel itself. After installing, you will get a new tab in your browser DevTools titled "Svelte". The DevTools panel will only work on sites with dev
mode enabled, which should work out-of-the-box when you're running your Svelte app locally.
Key Features:
- Zero-configuration: Run your application in development mode and have everything working
- Real-time Component Tree: Svelte component hierarchy visualization in real-time, deeper understanding of your application structure and identify relationships between components easily
- Interactive State Inspection: Modify and experiment with component states effortlessly in one place, and easily see events and other state
- Dark Mode Support: Enjoy the sleek and user-friendly interface in both light and dark modes
- Open Source and Community-Driven: This extension is open source and actively maintained by the Svelte community
This extension requires permissions to access the tab's content, data will be processed locally in your browser and cleared after each session.
