How can you render and edit DOCX Editor files in React with Syncfusion?

You can render and edit DOCX files in React with Syncfusion effectively using the Syncfusion® React DOCX Editor component. This dedicated UI component provides a rich, Word-like editing experience, enabling users to create, edit, view, and print Word documents (DOCX, WordML, DOC, RTF, TXT) directly within your React applications, and can be easily integrated with server APIs to load and save documents.

This article provides a step-by-step guide to render and edit DOCX files in React with Syncfusion using React DOCX Editor.

Prerequisites

Before starting, ensure your development environment meets the following requirements:

Node.js: Version 14.0.0 or above
React: Version 15.5.4 or higher.
A running ASP.NET Core Web API backend to process the DOCX files.

For detailed system requirements, refer to the documentation.

Step-by-step guide to render and edit a DOCX file in React

Step 1 : Create or use a React application

To render and edit DOCX files in your React application, you first need an existing application or create a new React application. Refer to the documentation to create a new React application.

Step 2 : Install the Syncfusion® DOCX Editor package

All the Syncfusion® React component packages are available in npmjs.com public registry. To install the Document Editor component, use the following command

npm install @syncfusion/ej2-react-documenteditor --save

Step 3: Add the required CSS styles

For the editor to render correctly, you must import its stylesheet. The simplest way to do this is to add the import statement to your src/App.css file.
Open src/App.css and add the following lines at the top:

@import '../node_modules/@syncfusion/ej2-base/styles/material.css';
@import '../node_modules/@syncfusion/ej2-buttons/styles/material.css';
@import '../node_modules/@syncfusion/ej2-inputs/styles/material.css';
@import '../node_modules/@syncfusion/ej2-popups/styles/material.css';
@import '../node_modules/@syncfusion/ej2-lists/styles/material.css';
@import '../node_modules/@syncfusion/ej2-navigations/styles/material.css';
@import '../node_modules/@syncfusion/ej2-splitbuttons/styles/material.css';
@import '../node_modules/@syncfusion/ej2-dropdowns/styles/material.css';
@import "../node_modules/@syncfusion/ej2-documenteditor/styles/material.css";
@import "../node_modules/@syncfusion/ej2-ribbon/styles/material.css";

Step 4: Set Up the Web API for Document Processing

As the Syncfusion® DOCX editor client-side script requires the document in SFDT file format, you can convert the Word documents (.dotx, .docx, .dot, .doc), rich text format documents (.rtf), and text documents (.txt) into SFDT format by using this Web API.

Create an ASP.NET Core Web API with the following example code for importing Word documents into Document Editor component.

[AcceptVerbs("Post")]
       [HttpPost]
       [EnableCors("AllowAllOrigins")]
       [Route("Import")]
       public string Import(IFormCollection data)
       {
           if (data.Files.Count == 0)
               return null;
           Stream stream = new MemoryStream();
           IFormFile file = data.Files[0];
           int index = file.FileName.LastIndexOf('.');
           string type = index > -1 && index < file.FileName.Length - 1 ?
               file.FileName.Substring(index) : ".docx";
           file.CopyTo(stream);
           stream.Position = 0;

           //Hooks MetafileImageParsed event.
           WordDocument.MetafileImageParsed += OnMetafileImageParsed;
           WordDocument document = WordDocument.Load(stream, GetFormatType(type.ToLower()));
           //Unhooks MetafileImageParsed event.
           WordDocument.MetafileImageParsed -= OnMetafileImageParsed;

           string json = Newtonsoft.Json.JsonConvert.SerializeObject(document);
           document.Dispose();
           return json;
       }

Refer and reuse the GitHub Web Service example or Docker image for hosting your own web service and use it for the serviceUrl property.

Step 5 : Add the DOCX Editor to a React Component

Now that the Syncfusion® DOCX Editor packages are installed and styles are imported, you can add the DOCX editor to your React application. You will typically replace the default content of your src/App.tsx with the DocumentEditorContainer Component.
Open your src/App.tsx file and replace its content with the following code:

import React, { useRef, useEffect } from 'react';
import './App.css';
import { DocumentEditorContainerComponent, Ribbon } from '@syncfusion/ej2-react-documenteditor';
DocumentEditorContainerComponent.Inject(Ribbon);

function App() {
 const containerRef = useRef<DocumentEditorContainerComponent | null>(null);
 return (
   <div>
     <DocumentEditorContainerComponent
       id="container"
       ref={containerRef}
       height={'100vh'}
       toolbarMode="Ribbon"
     />
   </div>
 );
}

export default App;

Step 6 : Add the license key

From v20.1.047 onwards, it is necessary to register a license key for Syncfusion® React components. For more information on obtaining and registering your license key, please refer to the documentation.

Step 7 : Initial client-side view

At this point, if you run your React application without a connected server, you will see the DOCX Editor’s UI, but it might not fully function until the serviceUrl points to a live backend. Open your terminal in the React project directory and run:

npm start

Step 8: Configure service URL and Load Document

Once your ASP.NET Core Web API service is running (e.g., http://localhost:62869/api/documenteditor/), update the serviceUrl property in your src/App.tsx file to point to this URL. Then, add the following code snippet to load the document in the DOCX Editor.

import React, { useRef, useEffect } from 'react';
import './App.css';
import { DocumentEditorContainerComponent, Ribbon } from '@syncfusion/ej2-react-documenteditor';
DocumentEditorContainerComponent.Inject(Ribbon);

function App() {
 const containerRef = useRef<DocumentEditorContainerComponent | null>(null);
 useEffect(() => {
   const container = containerRef.current;
   if (container) {
     const uploadDocument = new FormData();
     uploadDocument.append('DocumentName', 'Getting Started.docx');
     const loadDocumentUrl = container.serviceUrl + 'LoadDocument';
     const httpRequest = new XMLHttpRequest();
     httpRequest.open('POST', loadDocumentUrl, true);
     httpRequest.onreadystatechange = () => {
       if (httpRequest.readyState === 4) {
         if (httpRequest.status === 200 || httpRequest.status === 304) {
           if (container.documentEditor) {
             container.documentEditor.open(httpRequest.responseText);
           }
         }
       }
     };
     httpRequest.send(uploadDocument);
   }
 }, []);

 return (
   <div>
     <DocumentEditorContainerComponent
       id="container"
       ref={containerRef}
       height={'100vh'}
       serviceUrl="http://localhost:62869/api/documenteditor/"
       toolbarMode="Ribbon"
     />
   </div>
 );
}

export default App;

Step 9: Run the application

To see the Syncfusion® DOCX Editor in action with a functioning backend, ensure your Web API service is running, then run your React application.

Start your Web API service
Run your React application: Open your terminal in the React project directory and run:

npm start

Your browser will open to http://localhost:3000, displaying a fully functional DOCX Editor embedded in your React application, with the default document loaded and ready for editing.
