Server requirment

[behrouzbk]

Hi,
I have developed a web application and developed with VueJs 2 , NodeJS, ExpressJs and PostgreSQL . I want to setup an internal server and deploy the application on it.

Please help and let me know what OS and Minimum Hardware Spec and maybe other software tools the server should have.

I see you have used nodejs, so the os if that can install the nodejs will be fit for you. I think the common os, such as Windows, Ubuntu, CentOS and so on, can deploy your application.

I have asked this question to GPT, the follow is the answer:

There are different ways to deploy a web application, depending on your preferences and requirements. One common way is to use a Linux-based operating system, such as Ubuntu, CentOS, or Debian, as the server platform. Linux is widely used for web development and hosting, and it offers many advantages, such as stability, security, performance, and flexibility. You can install Linux on a physical machine, or use a virtual machine or a cloud service provider.

The minimum hardware specifications for the server depend on the size and complexity of your application, as well as the expected traffic and load. However, a general recommendation is to have at least 2 GB of RAM, 20 GB of disk space, and a dual-core processor. You can always scale up or down your resources as needed.

Besides the operating system, you will also need some software tools to deploy your application. These include:

• Node.js: This is the runtime environment that allows you to run your ExpressJs server and execute your JavaScript code. You can download and install Node.js from its official website¹, or use a package manager such as apt or yum.
• PostgreSQL: This is the database system that stores your application data. You can download and install PostgreSQL from its official website², or use a package manager such as apt or yum. You will also need to configure PostgreSQL to allow remote connections from your application server.
• Vue CLI: This is a command-line tool that helps you build and serve your VueJs front-end. You can install Vue CLI globally using npm, which is the package manager for Node.js. To install Vue CLI, run this command in your terminal: npm install -g @vue/cli
• Nginx: This is a web server that serves your static files, such as HTML, CSS, and JavaScript files, and acts as a reverse proxy for your ExpressJs server. You can download and install Nginx from its official website³, or use a package manager such as apt or yum. You will also need to configure Nginx to route requests to your ExpressJs server.

To deploy your application on the server, you will need to follow these steps:

• Copy your application files to the server using a file transfer tool such as scp or rsync.
• Install and configure the software tools mentioned above on the server.
• Build your VueJs front-end using Vue CLI. To do this, navigate to the directory where your VueJs project is located, and run this command in your terminal: vue-cli-service build. This will create a dist folder that contains the built files for your front-end.
• Serve your VueJs front-end using Nginx. To do this, copy the contents of the dist folder to the document root of Nginx, which is usually /var/www/html. Then edit the Nginx configuration file, which is usually /etc/nginx/nginx.conf, and add a server block that looks like this:

server {
    listen 80;
    server_name example.com; # replace with your domain name
    root /var/www/html; # replace with your document root
    index index.html;
    location / {
        try_files $uri $uri/ /index.html;
    }
    location /api {
        proxy_pass http://localhost:3000; # replace with your ExpressJs port
    }
}

This configuration tells Nginx to serve the static files from the document root, and proxy any requests that start with /api to your ExpressJs server.

• Restart Nginx to apply the changes. To do this, run this command in your terminal: sudo systemctl restart nginx
• Start your ExpressJs server using Node.js. To do this, navigate to the directory where your ExpressJs project is located, and run this command in your terminal: node app.js (or npm start if you have defined a start script in your package.json file). This will start your ExpressJs server on port 3000 (or any port you have specified in your code).
• Test your application by visiting http://example.com (or http://localhost if you are testing locally). You should see your VueJs front-end rendered in the browser, and be able to interact with your ExpressJs back-end through the /api endpoints.

My answer end. This is what i know the common os and Hardware Spec. If you have other question, you can see other answer.

Hello @behrouzbk,

It would be hard to estimate more on the server requirements without understanding more about the use case of your application.

If you are able to provide more details, it would be helpful!
