Edit or write file in onlyoffice using ReactJS or NodeJS

Is it possible to edit or write in file using ReactJS (frontend) or NodeJS (backend) ?

This is my current Integration of onlyOffice in ReactJS using @onlyoffice/document-editor-react

<div className="h-[94vh] w-full ">
          <DocumentEditor
            style={{ height: "100%" }}
            id="docxEditor"
            documentServerUrl="<document_server_url>"
            config={{
              document: {
                fileType: "docx",
                "title": "sample4.docx",,
                url: "<document_URL>",
                key: "<key>",
              },

              documentType: "word",
              editorConfig: {
                callbackUrl: "<my-url>"
              },
            }}
            events_onDocumentReady={onDocumentReady}
            onLoadComponentError={onLoadComponentError}
          />
       </div>

Hello @harshilsharma

Please clarify your question as it is not quite clear. Do you want to edit documents via ONLYOFFICE Docs (Document Server) in your React application? If so, please visit these pages to find out how the processes of opening a file and saving of file work in Document Server:
