Resumable Upload API

This article demonstrates how to use the response object from the Generate File Resumable Upload Url endpoint to upload a file to a site's Media Manager.

Note: Due to limits on the size and duration of files that you can upload, we recommend using the importFile() function. See Wix Media: Supported Media File Types and File Sizes for more details.

Authorization

This endpoint uses the uploadToken from the response for authorization. No additional authorization is needed.

Syntax

PUT {{generateFileResumableUploadUrlResponse.uploadUrl}}/{{generateFileResumableUploadUrlResponse.uploadToken}}

Query Params

Name	Type	Optional	Description
filename	string	no	File name that appears in the Media Manager. Include the file's extension in the name to prevent potential errors.

Example

Implement a Resumable Upload Client using TUS Protocol

In this example we use tus-js-client to implement a resumable upload using the TUS protocol.

Request

async function resumableFileUpload(resumableUploadUrlResponse: GenerateFileResumableUploadUrlResponse): Upload {
  // get the file content to upload
  const fileName = 'imageExample.jpg';
  const fileContent = await fs.createReadStream(path.join(__dirname, '..', 'files', fileName));

  const mimeType = 'image/jpeg';

  const params = {
    filename: fileName,
    contentType: mimeType,
    token: resumableUploadUrlResponse.uploadToken
  };

  // Wrap the resumable upload session in a promise to wait for the upload to finish.
  await new Promise(async (resolve, reject) => {
    // Create a new TUS upload.
    const upload = new tus.Upload(fileContent, {
      // Use the uploadUrl from the response of the generate URL endpoint.
      endpoint: resumableUploadUrlResponse.uploadUrl,
      // Enable tus-js-client to automatically retry on errors.
      retryDelays: [0, 3000, 5000, 10000, 20000],
      // TSend parameters to the upload server to indentify the file and authentication token.
      metadata: {
        filename: fileName,
        contentType: mimeType,
        token: resumableUploadUrlResponse.uploadToken
      },
      // Callback for errors that can't be fixed using retries.
      onError: function (error) {
        console.log('Failed because: ' + error);
        reject(error);
      },
      // Callback for reporting upload progress.
      onProgress: function (bytesUploaded, bytesTotal) {
        var percentage = (bytesUploaded / bytesTotal * 100).toFixed(2);
        console.log(bytesUploaded, bytesTotal, percentage + '%');
      },
      // Callback for once the upload is completed.
      onSuccess: function () {
        console.log('Download %s from %s', fileName, upload.url);
        resolve(true);
      }
    });

    upload.start();
  });

  // PUT request to finalize the upload.
  // Note that we concatenate the URL and token of the resumable upload response.
  const result = await httpClient.put(
    `${resumableUploadUrlResponse.uploadUrl}/${resumableUploadUrlResponse.uploadToken}`,
    {}, { params: { filename: fileName } }
  );
}
