Angular FileManager - Object

The Object file system provider works with a file system represented by an in-memory array of JSON objects.

import ObjectFileSystemProvider from "devextreme/file_management/object_provider"
Type:

Object

Assign the array to the data property. Data object fields should have conventional names listed in the data description. Otherwise, specify [fieldName]Expr properties: nameExpr, sizeExpr, dateModifiedExpr, and so on.

The following code shows how to bind the FileManager to the Object file system provider:

jQuery
index.js
$(function() {
    $("#fileManagerContainer").dxFileManager({
        fileSystemProvider: new DevExpress.fileManagement.ObjectFileSystemProvider({            
            data: [ 
                // ...
                // Data objects that represent files and directories
                // ...
            ],
            thumbnailExpr: "icon",
            // ...
        })
        // A shortcut that can be used if object fields have conventional names
        fileSystemProvider: [ 
            // ...
            // Data objects that represent files and directories
            // ...
        ]
    });
});
