Deploy this FullStack Ecommerce app to Digital Ocean cloud servers, Add a Domain name and use Cloudflare's CDN to your

application along with free SSL.** 🚀

** Code for React Presentation Layer - server.js

const express = require('express');
const compression = require('compression');
const path = require('path');
const app = express();
 
app.use(compression());
app.use(express.static(path.join(__dirname, 'build')));
 
app.get('*', function(req, res) {
    res.sendFile(path.join(__dirname, 'build', 'index.html'));
});
 
const PORT = process.env.PORT || 3000;
 
app.listen(PORT, () => {
    console.log(`App is running on port ${PORT}`);
});

Setting up the Process for Deployment

** Code nginx sites configuration **

location /api {
    proxy_pass http://localhost:8000;
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection 'upgrade';
    proxy_set_header Host $host;
    proxy_cache_bypass $http_upgrade;
}
 
location / {
    proxy_pass http://localhost:3000;
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection 'upgrade';
    proxy_set_header Host $host;
    proxy_cache_bypass $http_upgrade;
}

Deployment Procedure

Step 1 --- Create a New Droplet

  1. Sign up or Sign in to a new account in Digital Ocean(DO).
  2. Open the "create" drop down menu and click the "Droplets" link - takes you to the 'Create Droplets' page. Follow the configuration options before creating a new server.
  3. Select Ubuntu OS for your server:
  4. Choose the Basic Plan for $5/month that gives enough processing power to run a medium-sized web app. However, it can be upgraded later according to the need.
  5. If additional block storage is required for storing static assets such as Images, Videos, and more, you can add it. However, it is not necessary.
  6. Pick a Data Center closest to your region.
  7. [Important] Create a root password - for accessing Droplet.
  8. Choose how many droplets to be deployed. Also, choose a hostname which gives the server a name to remember it by( Adding a tag is optional.
  9. [optional] Choose backups of your droplet generated every week.
  10. Click Create Droplet to create your droplet with those configuration.

Step 2 --- Server Setup Access

  • Access droplet as the 'root' user by using the password for root created in the last step. In the terminal of your computer, run the following command:
    > ssh root@<server_ip_address>
  • [!important] Using root access on a regular basis is discouraged. So, create an alternative account with limited scope, similar to IAM in AWS. Run the following command while logged in as root user in the droplet:
    > adduser <username>
  • Since, this user has limited privileges, to give the new root user privileges, follows the command:
    > usermod -aG sudo <username>

Step 3 --- Installing Node and MongoDB

Node Installation

  • Installing Node.js with Apt Using a NodeSource PPA:
$ cd ~
$ curl -sL https://deb.nodesource.com/setup_14.x -o nodesource_setup.sh

  • Inspect the contents of the downloaded script with nano (or your preferred text editor): nano nodesource_setup.sh

  • When you are satisfied that the script is safe to run, exit your editor, then run the script with sudo: sudo bash nodesource_setup.sh

  • You can now install the Node.js package in the same way you did in the previous section: sudo apt install nodejs

  • Verify that you’ve installed the new version by running node with the -v version flag: node -v

  • Refresh your local package index first and install node by typing:
    sudo apt update
    sudo apt install nodejs

  • Check that the install was successful by querying node for its version number: nodejs -v

  • Install npm: sudo apt install npm

  • Must include MongoDB's dedicated package repository to your APT sources.

  • Run the following command in the terminal:
    cd
    curl -fsSL https://www.mongodb.org/static/pgp/server-4.4.asc | sudo apt-key add -

  • Double check that the key was added correctly.
    apt-key list This will return the MongoDB key somewhere in the output: 

/etc/apt/trusted.gpg
--------------------
pub   rsa4096 2019-05-28 [SC] [expires: 2024-05-26]
      2069 1EEC 3521 6C63 CAF6  6CE1 6564 08E3 90CF B1F5
uid           [ unknown] MongoDB 4.4 Release Signing Key <packaging@mongodb.com>
. . .
  • Run the following command that creates a file in the sources.list.d directory named mongodb-org-4.4.list .
    $ echo "deb [ arch=amd64,arm64 ] https://repo.mongodb.org/apt/ubuntu focal/mongodb-org/4.4 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-4.4.list
  • Update server's local package index so APT knows where to find the mongodb-org package:
    sudo apt update
    sudo apt install mongodb-org [Press Y] when prompted, and ENTER to confirm installation of the package.

Nginx Installation:

  • Run the following command to install nginx
    sudo apt-get install nginx

Starting MongoDB Service and Testing Database

  1. Manage MongoDB using various systemctl commands.
  2. Run the following command to start the MongoDB service: $ sudo systemctl start mongod.service
  3. Now, check the service's status. $ sudo systemctl status mongod
  4. The following output is returned indicating that the service is up and running:
Output

  1. If there is no error, enable MongoDB service to start up at boot: sudo systemctl enable mongod
