When multiple users edit separate copies of the same Word document, teams can quickly lose track of the latest version, duplicate changes, or spend unnecessary time merging feedback manually. In this webinar, “Eliminate Document Version Conflicts with Real-Time Collaborative Editing in React,” we explored how to build a real-time, collaborative .docx editing workflow using the Syncfusion® [React DOCX Editor](https://www.syncfusion.com/docx-editor-sdk/react-docx-editor) . Presenter **Anantha Lakshmi Kannan** demonstrated how users can browse documents from Azure Blob Storage, open them in a browser-based editor, share a collaboration link with teammates, and work together in the same document session with live updates, user presence, and synchronized comments. If you missed the webinar or would like to review it, the recording has been uploaded to our [YouTube channel](https://www.youtube.com/watch?v=NkpVPQlZSIM) and is embedded below. ## Why collaborative document editing matters In many applications, document collaboration still depends on downloading files, sending copies, and manually passing updates between users. This creates confusion when more than one person is involved in the review or editing process. A real-time, collaborative editing workflow helps solve this by giving users a single, shared document experience. Instead of working on different versions, users join the same session and see updates as they happen. This keeps everyone aligned and reduces the friction caused by repeated handoffs, delayed updates, and version mismatches. ## Demo The demo application connected document storage, editing, sharing, and synchronization into one continuous workflow. Users could: - Browse Word documents stored in Azure Blob Storage. - Select a .docx file from a file manager interface. - Open the document in the Syncfusion React DOCX Editor. - Enter a username before joining the editing session. - Generate and open a shared collaboration link. - View active collaborators in the editor title bar. - Edit the same document from multiple browser sessions. - See document changes synchronized in real time. ## Technology stack The sample used a React client and an ASP.NET Core back end. The React client handled the user experience, including file browsing, editor rendering, shared-link navigation, username capture, title bar updates, and SignalR connection handling. The ASP.NET Core back end handled document loading, Azure Blob Storage access, editor services, collaboration APIs, SignalR communication, Redis coordination, and background processing for collaboration tasks. The main technologies used were: - Syncfusion [React DOCX Editor](https://www.syncfusion.com/docx-editor-sdk/react-docx-editor) for browser-based Word document editing. - Syncfusion [React File Manager](https://www.syncfusion.com/react-components/react-file-manager) for browsing documents. - [Azure Blob Storage](https://azure.microsoft.com/en-us/products/storage/blobs/?msockid=0cc0144d4545641c1d0102a544d66580) for storing source documents. - ASP.NET Core for back-end APIs and editor services. - SignalR for establishing the real-time communication channel and broadcasting collaboration events among connected users. - Redis for coordinating collaboration state, document versions, and ordered edit operations. ## How the workflow works The webinar followed a simple three-step workflow: document access, editor integration, and real-time collaboration. ### 1. Document access Users begin by browsing Word documents stored in Azure Blob Storage through a file manager interface. When a document is selected, the app generates a collaboration room ID and opens the file with the required session context. The initiating user can then share a URL containing that session information so other users can join the same collaboration room. ### 2. Editor integration Next, the user enters a name before joining the session. The selected .docx file is then loaded into the Syncfusion React DOCX Editor, along with the document name, room details, and collaboration settings. ### 3. Real-time collaboration Finally, the React client connects to the ASP.NET Core back end through SignalR and joins the collaboration room. As users edit, incremental edit operations, rather than the complete document, are sent to the server. The operations are coordinated through the collaboration layer and broadcast to other connected users so each editor can remain synchronized. ## Time stamps 1.
