React FileManager - Remote
Set the endpointUrl property to specify the endpoint used to access and modify the file system.
The server should return data objects of the following structure:
- {
- name: "MyFile.jpg",
- size: 1024,
- dateModified: "2019/05/08",
- thumbnail: "/thumbnails/images/jpeg.ico",
- isDirectory: true,
- hasSubDirectories: true
- }
Fields in this structure have conventional names that you can change via [fieldName]Expr properties: nameExpr, sizeExpr, dateModifiedExpr, and so on.
The following code shows how to bind the FileManager to the Remote file system provider:
- import React from 'react';
- import 'devextreme/dist/css/dx.light.css';
- import FileManager from 'devextreme-react/file-manager';
- import RemoteFileSystemProvider from 'devextreme/file_management/remote_provider';
- const remoteFileProvider = new RemoteFileSystemProvider({
- endpointUrl: 'https://js.devexpress.com/Demos/Mvc/api/file-manager-file-system-scripts'
- });
- class App extends React.Component {
- render() {
- return (
- <FileManager
- fileSystemProvider={remoteFileProvider}>
- {/* ... */}
- </FileManager>
- );
- }
- }
- export default App;
On the server-side, you need to process file management requests. DevExtreme provides helpers for ASP.NET MVC and ASP.NET Core that do this. To view the server-side code, navigate to the FileManagerApiController.cs
tab in the following demo:
