A Svelte IDE like no other. Embrace the storm. SvelteStorm is a new and improved open-source integrated developer environment (IDE). SvelteStorm is specifically tailored to provide all of the essential tools a Svelte developer needs to build a Svelte application. The IDE contains a code editor, a terminal environment, a file directory, a browser view, developer tools, and a component state viewer. SvelteStorm was built using Svelte and Electron and is downloadable for Windows and Mac operating systems. With the new and improved SvelteStorm, developers can now observe state changes in their applications using the Time Travel Debugger tool. From its modernized and clean UI, to its quick loading time and component state window, SvelteStorm is a rising star for the Svelte community.

New Features and Improvements

  1. Time Travel Debugger tool
  2. Real-time D3 Component Visualization
  3. Updated Browser window and Terminal
  4. Quality of Life changes
  5. A Cleaner & Bold Theme Style

How To Use SvelteStorm

  1. Click on the 'File' menu button in the top-left corner, then open a file or folder to begin editing. (You can also use CTRL+F to open a folder with a shortcut)
  2. When a Svelte project is opened, you will notice the File Directory populates showing all files in the directory. From here you can open, edit, and save files.
  3. To use the browser window, simply run any command to start your project and a new browser window will open to the localhost port your project is running on.
  4. To use the Time Travel Debugging feature, run the command npm run sdebug and a browser window will open with your project. Additionally, the Time Travel Debugging window will generate an initial snapshot of your project and a d3.js component hierarchy tree of your application. Any action on the browser window that creates a state change in your application will generate a new snapshot and update the d3.js tree. To view previous snapshots, click on the Snapshot button of your choice and you will see cards for each component that contain the component’s state at the time of the snapshot. As you navigate between Snapshots, you will notice your application state changes are reflected on your browser window. This will allow you to see how your applications state changes based on different events, happy debugging!
  5. Developer Tools are accessible via the 'Help' button in the top menu, or by using CTRL+D
  6. For more information, click on SvelteStorm's Website via the 'Help' button for VSCode users the link below can provide insight to potential installation issues: #57
