The Upload component provides multiple configuration options for fine tunning the way files are processed for upload.
The following file-processing operations are supported:
By default the selected files are immediately uploaded. If you set autoUpload option of the component to false, the upload will occur only when explicitly confirmed by the user through a button click.
Once a file is selected and unless the autoUpload option is set to
false, the Upload automatically initiates aPOSTrequest to the server.
The Upload allows the selection of multiple files by default. If you set the multiple option of the component to false, the selection will be limited to a single file.
The Upload allows handling and uploading the selected files as a single batch.
More information and example is available on the Batch Upload documentation page.
The selected files can be split into chunks and send to the server asynchronously through multiple requests.
More information and example is available on the Chunk Upload documentation page.
To enable sequential uploading of multiple files set the concurrent option to false. In this case each file upload request will be initiated only after the previous one has finished.
