Uploader-for-google-drive-resumable-upload-url NPM

uploader-for-google-drive-resumable-upload-url

version 2.x: Rewritten to support axios instead of request, as request has been deprecated by its maintainers.

version 1.x: This upload code was isolated from npm:decorated-google-drive and cleaned up a bit.

It handles the upload to a Google API v3 Resumable Upload URL provided from an external service, checking the URL points to Google, uploading a stream, checking the MD5 signature, and returning the new Google Drive file object.

Usage

Install

Pre-requisites are: 1. an external source of Google Drive API v3 Resumable Upload Urls (e.g. a service running npm: googleapis and perhaps npm: decorated-google-drive ) 1. npm:request for v1.x, npm:axios for v2.x

npm i request -S  # for v1.x only
npm i axios -S    # for v2.x only
npm i uploader-for-google-drive-resumable-upload-url -S

Use

const request = require('request'); // for v1.x
const axios = require('axios'); // for v2.x    
const uploader = require('uploder-for-google-drive-resumable-upload-url');
async function processTheUpload(url, pathToLocalSourceFile){
  const sourceStream = fs.createReadStream(pathToLocalSourceFile);
  const mimeType = "application/octet-stream"; // generic binary file
  const params = {
    sourceStream,
    mimeType,
    url,
    request // the npm: request module for v1.x
    axios // the npm: axios module for v2.x
  };
  const result = await uploader(params);
  return result;
}

Obtaining a Google Drive API v3 Resumable Upload URL

This module does not obtain the required url.

npm:decorated-google-drive can obtain the required url with drive.x.uploadDirector

Also, Google "Google Drive API v3 Resumable Upload" for more information.

OAuth2 Security Note

The service request (not provided in this code) to obtain a resumable upload url typically requires the Drive customer's Google Drive OAuth2 token.

Subsequently posting to the resumable upload url does NOT currently require an OAuth2 token. These urls are intended for uploading a specific folder and file to a specific customer.

Verifying Uploads

This code verifies "binary" uploads only by comparing a locally generated MD5 hash with one returned from the upload post to google. Uploads that have a streaming error or have a MD5 hash mismatch throw an error. Errors can be caught by subsequent code in the usual way with .catch(function(err){ ... }) or by using a try-catch block within an async function.

Text uploads are not verified.

A "binary" is any mimeType not beginning with text. Some source code types, although text in a broader sense, do not have mimeType text/plain but rather application/json or application/javascript and will undergo verification.

Tests

This module does not currently include its own tests. The module is a imported into npm:decorated-google-drive where it processes all uploads generated in that code. We regularly test that code.
