Let’s get started with the main steps!

Step #1: Create a New Node Express.js App

Express is a minimal and flexible Node.js web application framework that provides a robust set of features for web and mobile applications. To create the Express.js app, we will be using the Express generator. Type this command to install it.

sudo npm install -g express-generator

Next, create an Express.js app by typing this command.

express mean-uploader --no-view

Go to the newly created mean-uploader folder then install all NPM modules.

cd ./mean-uploader
npm install

Open this Express.js project with your IDE or Text Editor. To use Visual Studio Code, type this command.

code .

Now, we have this Express.js app structure for the mean-uploader app.

|-- app.js
|-- bin
|   `-- www
|-- node_modules
|-- package-lock.json
|-- package.json
|-- public
|   |-- images
|   |-- index.html
|   |-- javascripts
|   `-- stylesheets
|       `-- style.css
`-- routes
    |-- index.js
    `-- users.js

To check and sanitize the Express.js app, run this app for the first time.



npm start

Then you will see this page when open the browser and go to localhost:3000.

To make this Express.js server accessible from the different port or domain. Enable the CORS by adding this module.

npm i --save cors

Next, add this import to app.js after other require.

var cors = require('cors');

Then add this line to app.js before other app.use.
