How to deploy nodejs project online

Node.js is a very popular open source Javascript runtime environment that allows you to write efficient code using Javascript on the server side. Due to its flexibility, scalability, and fast response time, Node.js has become the preferred choice of many startups, enterprises, and enterprises. This article will explore how to deploy Node.js applications online during the application development process.

1. Selection of Deployment Tool

Before deploying a Node.js application, you need to choose a deployment tool. Node.js allows the use of many different tools, including PM2, Forever, Supervisor, and more. PM2 is a popular tool that allows you to manage processes, monitor server resources and deploy applications in a standardized way. If you use PM2, you can easily deploy your application to the server.

2. Make sure your code runs on the local server

Before you deploy your Node.js application to the server, you need to make sure it runs on the local server . If you use some dependencies during development, make sure they are available. You should also make sure that your code is configured correctly so that it works properly when run on the server. If you can't resolve any issues with your code in your local environment, it becomes more difficult to deploy it to a server.

3. Configuring the Server

Before deploying a Node.js application, you need to ensure that Node.js is installed on the server. If you are using a cloud server, you can usually find the option to install Node.js in your admin control panel. If you are using a local server, you will need to install Node.js manually.

Also, you need to configure the server to allow external access. If you are using a cloud server, you can configure network security group rules in the administrative control panel. If you are using a local server, you can change this in the firewall settings.

4. Deploy the application

Before deploying your Node.js application to a production environment, you need to remove sensitive information such as configuration files and passwords from the application from the code removed. Save this information in server environment variables so it can be easily accessed at any time.

Deploy the application to the server. You can use FTP or SSH (more reliable methods) to copy the files to the server.

To run the application on the server, you can use PM2 or other deployment tools. When using PM2, you can run the following command to start the application:

pm2 start app.js

5. Configure the reverse proxy

The reverse proxy can be used Standard ports forward HTTP requests from the web server to the Node.js server.

For example, if your Node.js application is running on port 3000, you can use a reverse proxy to forward all requests from port 80 to port 3000.

Using nginx as a reverse proxy, it can be configured to forward requests to Node.js applications.

6. Monitoring and Logging

It is important to monitor the resource usage of servers and applications. In addition to PM2, there are many tools for monitoring servers, such as Zabbix or New Relic.

Configure logging so you can view detailed information about application problems. It is recommended that logging be sent to all requested servers.

Summary

Deploying Node.js applications requires good planning and strict processes. Consider using a professional for deployment guidance to avoid any issues. Good luck deploying your Node.js application into production and delivering a great user experience!
