React FileManager - Custom

A custom provider allows you to implement custom APIs to access and use file systems.

import CustomFileProvider from "devextreme-react/custom"
Type: CustomTypes.default

Use the custom provider's methods to handle file operations (add, delete, rename, and so on).

The following code shows how to create a custom provider and bind the FileManager widget to it:

jQuery
index.js
$(function () {
    $("#file-manager").dxFileManager({ 
        fileProvider: new DevExpress.fileProviders.Custom({ 
            getItems: function(pathInfo) { 
                // Your code goes here
            }, 
            renameItem: function(item, name) { 
                // Your code goes here
            }, 
            createDirectory: function(parentDir, name) { 
                // Your code goes here
            }, 
            deleteItem: function(item) { 
                // Your code goes here
            }, 
            moveItem: function(item, destinationDir) { 
                // Your code goes here
            }, 
            copyItem: function(item, destinationDir) { 
                // Your code goes here
            }, 
            uploadFileChunk: function(fileData, chunksInfo, destinationDir) { 
                // Your code goes here
            }, 
            abortFileUpload: function(fileData, chunksInfo, destinationDir) { 
                // Your code goes here
            }, 
            uploadChunkSize: 1000 
        }) 
    });
});
