Many organizations still rely on Classic Pages with custom scripts and jQuery web parts. But as Microsoft gradually phases out the classic experience, the move to Mode
SharePoint
becomes inevitable.

💡 The good news — you don’t have to rewrite everything in TypeScript. You can simply wrap your existing JavaScript code in an SPFx Web Part that sequentially loads your legacy scripts (jquery.js, Helper.js, Assistant.js, etc.) using SPComponentLoader.loadScript.

This approach gives you:

  • a mode
    , supported container for your legacy logic;
  • lifecycle control and cleaner styling;
  • a smooth, gradual migration path — without breaking current functionality.

🔧 The result: your old Web Parts keep working on mode
pages, while your team gains time to refactor and integrate with REST API, Graph, and React components.


📈 Bottom line: moving to Mode
SharePoint doesn’t have to be a revolution — sometimes a smart SPFx wrapper is all you need to bridge the old and the new.
