Setup Https Nginx For Node Js

Setup Https Nginx For Node Js

Introduction to HTTPS and Nginx

HTTPS (Hyper Text Transfer Protocol Secure) is an industry standard, encrypted protocol used to establish a secure connection between two computers and associate it with a web-based application, such as an online store. As one of the most commonly used methods for securing web communications, HTTPS has become the de-facto standard in the industry.

Nginx is a web server application that is used to serve webpages and applications. It can be used for a variety of tasks, such as serving static webpages, providing reverse proxies for web applications, providing caching and load balancing for distributed systems, and many other tasks.

Nginx is popular among developers due to its high performance and easy configuration. It is an excellent choice for production-ready web applications due to its security and scalability.

Pre-Setup Requirements

Before you can start configuring your Nginx instance to support HTTPS connections, there are a few important requirements that you need to take care of first. The first is to obtain an SSL (Secure Sockets Layer) ceritificate. This certificate is used to encrypt the traffic between the client and the server. The second requirement is to setup your Nginx instance. This includes configuring it to accept incoming connections, serve static pages, and provide reverse proxies for web applications.

Configure Nginx to Accept HTTPS Connections

Once you have taken care of the pre-setup requirements, you can now start configuring Nginx to accept HTTPS connections. First, you need to make sure that the Nginx server is configured to accept HTTPS connections. You can do this by editing the main configuration file for the Nginx instance, which is typically located at /etc/nginx/nginx.conf. You can add the following line to the server block that you are configuring to accept HTTPS connections:

listen 443 ssl;

This will enable the Nginx server to accept HTTPS connections on port 443. Once this line has been added, you can save and close the configuration file and restart the Nginx server.

Configure Nginx to Serve Node.js Applications Over HTTPS

Now that the Nginx server has been configured to accept HTTPS connections, you can configure the server to serve Node.js applications over HTTPS. First, you need to create a virtual host to serve the Node.js application from. To do this, create a new file in the /etc/nginx/sites-available directory, let’s call it myapp.conf and add the following configuration to it:

server {
listen 443 ssl;

root /var/www/myapp;
index index.html;
ssl_certificate /etc/ssl/certs/myapp.crt;
ssl_certificate_key /etc/ssl/private/myapp.key;

location / {

This configuration will configure the Nginx server to use the SSL certificate located at /etc/ssl/certs/myapp.crt and the SSL key located at /etc/ssl/private/myapp.key to serve the Node.js application from the /var/www/myapp directory. Once you have created the myapp.conf file, you can enable the new virtual host by linking the file to the /etc/nginx/sites-enabled directory:

ln -s /etc/nginx/sites-available/myapp.conf /etc/nginx/sites-enabled/

Once this is done, restart the Nginx server again and your Node.js application should now be served over HTTPS.

Testing the Configuration

Once you have your Nginx instance configured to serve Node.js applications over HTTPS, you should test that it is working as expected. To do this, you can use a tool such as the Qualys SSL Labs server test, which will test various aspects of your SSL configuration. Once you have run the test, you should check for any warnings or errors that it reports and make sure that your configuration meets the industry security standards.


Securing web traffic is an important part of any web application, and setting up HTTPS with Nginx can help to ensure that sensitive data is transmitted securely. This tutorial has outlined the steps required to configure your Nginx server to accept HTTPS connections and serve Node.js applications over HTTPS.
