SvelteStorm is an open-source IDE with a built-in Debugging window for viewing and debugging your Svelte project in real-time

SvelteStorm 5.0

Table of Contents


A Svelte IDE like no other. Embrace the storm. SvelteStorm is an open-source integrated developer environment (IDE) specifically tailored to provide essential tools a Svelte developer needs to build a Svelte application. With the new and improved SvelteStorm 5.0, we've improved the developer experience with performance metrics, split view, search, and linting, in addition to the existing code editor, terminal environment, file directory, browser view, developer tools, and component state viewer. SvelteStorm is built using Svelte and Electron and is downloadable for Windows and Mac operating systems.

New Features and Improvements

  1. App Performance Metrics
  2. Split View
  3. Search
  4. Linting
  5. Quality of Life changes

How To Use SvelteStorm

  1. Click on the 'File' menu button (CTRL+F or CMD+F will also work) in the top-left corner, then open a file or folder to begin editing.
  2. When a Svelte project is opened, the File Directory populates with all of the files in that directory. From here, files can be opened, edited, and saved.
  3. To use the browser window, start your project (i.e run 'npm start') and a new browser window will open up to the local port the project is running on.
  4. To search through open files, CMD+F while in the editor window.
  5. To gather App Performance metrics:
    • Start the application with the command 'npm run performanceSS'.
    • Click on the 'Performance Dash' button on the top right of the application to view the dashboard,
    • Interact with the application - the dashboard will update automatically. Some of the web vitals will populate once the app is closed.
    • Click 'back' at the bottom of the window to exit the dashboard.
  6. To enable Split View, click the 'Split View' button on the top right of the application. Click 'back' at the bottom of the window to exit the dashboard.
  7. To use the Time Travel Debugging feature:
    • Run the command 'npm run sdebug' and a browser window will open with the project. Additionally, the Time Travel Debugging window will generate an initial snapshot of the project as well as a d3.js component hierarchy tree of the 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 any Snapshot button and cards containing each component's state at the time of the snapshot will appear. Application state changes are reflected in the browser window as you navigate between Snapshots - this allows for viewing of state changes based on different events.
  8. Developer Tools are accessible via the 'Help' button in the top menu, or by using CTRL+D
  9. 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:
