React

The ONLYOFFICE Docs React component integrates ONLYOFFICE Docs into React projects.

Prerequisites

This procedure requires Node.js (and npm).

Creating the demo React application with ONLYOFFICE Docs editor

This procedure creates a basic React application and installs an ONLYOFFICE Docs editor in it.

Create a new React project named onlyoffice-react-demo using the Create React App package:
```
npx create-react-app onlyoffice-react-demo
```
Go to the newly created directory:
```
cd onlyoffice-react-demo
```
Install ONLYOFFICE Docs React component from npm and save it to the package.json file with --save:
```
npm install --save @onlyoffice/document-editor-react
```
You can also use the following yarn command:
```
yarn add @onlyoffice/document-editor-react
```

Open the ./src/App.js file in the onlyoffice-react-demo project and replace its contents with the following code:

import {DocumentEditor} from "@onlyoffice/document-editor-react"
import React, {useRef} from "react"

function onDocumentReady(event) {
  console.log("Document is loaded")
}

function onLoadComponentError(errorCode, errorDescription) {
  switch (errorCode) {
  case -1: // Unknown error loading component
    console.log(errorDescription)
    break

  case -2: // Error load DocsAPI from http://documentserver/
    console.log(errorDescription)
    break

  case -3: // DocsAPI is not defined
    console.log(errorDescription)
    break
  }
}

export default function App() {
  return (
    <DocumentEditor
      id="docxEditor"
      documentServerUrl="http://documentserver/"
      config={{
        document: {
          fileType: "docx",
          key: "Khirz6zTPdfd7",
          title: "Example Document Title.docx",
          url: "https://example.com/url-to-example-document.docx",
        },
        documentType: "word",
        editorConfig: {
          callbackUrl: "https://example.com/url-to-callback.ashx",
        },
      }}
      events_onDocumentReady={onDocumentReady}
      onLoadComponentError={onLoadComponentError}
    />
  )
}

Replace the following lines with your own data:

http://documentserver/ - replace with the URL of your server;
https://example.com/url-to-example-document.docx - replace with the URL to your file;
https://example.com/url-to-callback.ashx - replace with your callback URL (this is required for the saving functionality to work).

This JavaScript file will create the App component containing the ONLYOFFICE Docs editor configured with basic features.

Test the application using the Node.js development server:
- To start the development server, navigate to the onlyoffice-react-demo directory and run:
```
npm run start
```
- To stop the development server, select on the command line or command prompt and press Ctrl+C.

Calling editor methods in the React component

Add the DocEditor.instances parameter to the window object and get the editor object from it by the editor ID:
```
const documentEditor = window.DocEditor.instances["docxEditor"]
```

Call any editor method from this object:

documentEditor.showMessage("Welcome to ONLYOFFICE Editor!")

Example:

const onDocumentReady = () => {
  const documentEditor = window.DocEditor.instances["docxEditor"]

  documentEditor.showMessage("Welcome to ONLYOFFICE Editor!")
}

Deploying the demo React application

The easiest way to deploy the application to a production environment is to install serve and create a static server:

Install the serve package globally:
```
npm install -g serve
```
Serve your static site on the 3000 port:
```
serve -s build
```
Another port can be adjusted using the -l or --listen flags:
```
serve -s build -l 4000
```
To serve the project folder, go to it and run the serve command:
```
cd onlyoffice-react-demo
serve
```

Now you can deploy the application to the created server:

Navigate to the onlyoffice-react-demo directory and run:
```
npm run build
```
The build directory will be created with a production build of your app.
Copy the contents of the onlyoffice-react-demo/build directory to the root directory of the web server (to the onlyoffice-react-demo folder).

The application will be deployed on the web server (http://localhost:3000 by default).
