How to Upload Files to Google Drive with Node.js, Express and Multer?

Uploading files to a cloud storage like Google Drive is a common need for web applications. If you’re building a Node.js application, you can use Express and Multer to do this easily.

Make sure you have Node.js installed

Node.js is a platform for building server-side applications. You can install it on your computer by following the instructions on their website: https://nodejs.org/en/.

Once you’ve installed node, make sure that you have the latest version by running this command in your terminal:

“`bash

node -v“`

Install Express and Multer

To get started, you will need to install the following modules:

Express (a framework for building web applications)
Multer (an upload middleware for Express).
* Make sure that you have the latest versions of these packages by running npm install –save express and npm install –save multer , respectively.

Create a server.js file

In the root directory of your project, create a new file called server.js.

Add the following code to this file:

Define the GET route that returns the form

In the next step, you’ll define a GET route that returns the form. Follow these steps:

Add a new file named `routes/get-form.js`.
Open it in your code editor and add this code to set up Express’ route handler:

“`javascript

var express = require(‘express’);

var bodyParser = require(‘body-parser’);

var multer = require(‘multer’);

const app = express();

“`

Add this line after defining `app`: “`javascript app.use(bodyParser());“` This enables our application to accept data from POST requests (when someone fills out or submits our contact form).

Define the POST route to handle file uploading

Define the POST route to handle file uploading.
Use Multer, a popular Node.js module for handling multipart/form-data requests, to upload the file.
Use multer.mount() to define your route as well as which middleware you want to use with it (in this case, we’re using express-fileupload).
When a user submits their form, call multer’s upload() function and pass in two arguments: an instance of FormData (which will contain all of your form data) and an object containing information about where you want files uploaded on Google Drive or Dropbox etc.. In this example we’re uploading directly into our server’s root directory so we pass null for dest_.

In this tutorial, you learned how to upload files to Google Drive with Node.js, Express and Multer.

You can use the code from this tutorial as a starting point for your own projects.
You need to have Node.js installed on your computer in order for it work properly (you can download it here).
The next step is installing Express and Multer through npm: `npm install express multer` (or `yarn add express multer` if you prefer Yarn). This will create two new folders called node_modules and lib/express respectively; these folders contain all of the necessary dependencies needed by our server-side codebase!

In this tutorial, you learned how to upload files to Google Drive with Node.js and Express. You also used Multer for file uploading and handling errors.
