Node.js - Google Resumable Upload

Allows users to upload files or any size to various Google services using the resumable upload API.

Usage

Install

npm i node-google-resumable-upload

Tokens

This application does not get the required Google OAuth tokens, however the token can be refreshed if the refreshToken value is set to true and the clientId and clientSecret values are set.

Uploading A Single File (Google Drive)

const UploadFile = require('node-google-resumable-upload')
let uploadFile = new UploadFile();
uploadFile.tokens = token; // OAuth token
uploadFile.filePath = 'path/To/File';
uploadFile.metadataBody = {
    name: 'file name',
    parents: ['parentsFolderId']
}
uploadFile.refreshToken = true; // Optional: Refreshed expired access token
uploadFile.clientId = ''; // Required if refreshToken = true. 
uploadFile.clientSecret = ''; // Required if refreshToken = true. 
uploadFile.upload(); // Initalize upload

uploadFile.on('error', (e) => {
    console.log(e)
})
    
/*
* Tracks progress of file upload. Based on chunk size, not time.
 */
uploadFile.on('progress', (p) => {
    console.log(p)
})

/*
* Returns the body of the final upload.
 */
uploadFile.on('success', (s) => {
    console.log(s)
    
    /*
    * Ex return when uploading image file to Google Drive
     */
    s = {
        kind: 'drive#file',
        id: 'abc123',
        name: 'file name',
        mimeType: 'image/jpeg'
    }
})

Uploading Multiple Files (Google Drive)

const UploadFile = require('node-google-resumable-upload')
let files = ['/Users/user1/path/to/file1', '/Users/user1/path/to/file2']

files.forEach((file) => {
    let uploadFile = new UploadFile();
    uploadFile.tokens = token; // OAuth token
    uploadFile.metadataBody = {
        name: file.split('/').pop() 
    }
    uploadFile.refreshToken = true;
    uploadFile.clientId = '...';
    uploadFile.clientSecret = '...'
    uploadFile.filePath = file
    uploadFile.upload();

    uploadFile.on('error', (e) => {
        console.log(`File ${file} error: ${e}`)
    })

    uploadFile.on('progress', (p) => {
        console.log(`File ${file} progress: ${p}`)
    })

    uploadFile.on('success', (s) => {
        console.log(s)
    })
})

const UploadFile = require('node-google-resumable-upload')
let uploadFile = new UploadFile();
uploadFile.tokens = token; // OAuth token
uploadFile.filePath = 'path/To/File';
uploadFile.initMethod = 'PATCH'
uploadFile.pathParam = "fileId"; // The unique file id as returned from inital uplaod

// uploadFile.metadataBody = {} ! Do NOT specify metadata like new parents

// Optional:
uploadFile.refreshToken = true; // Optional: Refreshed expired access token
uploadFile.clientId = ''; // Required if refreshToken = true. 
uploadFile.clientSecret = ''; // Required if refreshToken = true. 

uploadFile.upload(); // Initalize upload

uploadFile.on('error', (e) => {
    console.log(e)
})
    
/*

uploadFile.on('success', (s) => {
    console.log(s)
    
    /*
    * Ex return when uploading image file to Google Drive
