![]() ![]() Since 2012, when the popularity of IoT rose dramatically, Node.js has become one of the preferred solutions for enterprises and organizations seeking to develop their private and public IoT systems. IoT may consist of thousands of such devices, which makes it challenging to manage requests and data streams from and between the devices. Normally, IoT systems pass data from devices to servers and from servers to applications that process it and display it to users. IoT (Internet of Things) is a network of devices such as sensors, beacons, actuators, and any other items embedded with electronics that enables them to send and exchange data. Read more about common use cases for Node.js apps Non-blocking I/O makes Node.js very fast, lightweight, scalable, and efficient in handling data-heavy and I/O-heavy workloads characteristic of several types of web applications. Node.js is a JavaScript runtime environment built upon event-driven programming that enables non-blocking I/O (Input/Output) capable of serving multiple concurrent events in a single thread. We will present six most popular solutions, including IoT applications, applications built around microservice architecture, real-time chats, real-time collaboration tools, streaming apps, and Single Page Applications (SPAs). Sudo nano /etc/nginx/sites-available/defaultĪdd the following to the location part of the server block server_name can be used efficiently in many kinds of applications. Install NGINX and configure sudo apt install nginx Now we want to setup a firewall blocking that port and setup NGINX as a reverse proxy so we can access it directly using port 80 (http) 7. ![]() You should now be able to access your app using your IP and port. ![]() Pm2 start app (or whatever your file name) Setup PM2 process manager to keep your app running sudo npm i pm2 -g Npm start (or whatever your start command)Ħ. Install dependencies and test app cd yourproject There are a few ways to get your files on to the server, I would suggest using Git git clone yourproject.gitĥ. Install Node/NPM curl -sL | sudo -E bash. I will be using the root user, but would suggest creating a new user 3. If you use the referal link below, you get $10 free (1 or 2 months) Steps to deploy a Node.js app to DigitalOcean using PM2, NGINX as a reverse proxy and an SSL from LetsEncrypt 1. ![]()
