Word document report generator

Installation of the service

cd report-generator
npm install

• Build the project

npm run build

Running the service

The service can be runned directly from the command line with:

npm start

or it can be build and runned watching for file changes

npm run dev

Deploy on server

Run as service

To allow the microservice to run as system service, first you must install pm2:

npm i -g pm2

After that, you must create the ecosystem file to launch the service:

nano ecosystem.config.js

The ecosystem.config.js file contains the following lines:

module.exports = {
  apps : [{
    name: 'REPORT-API',
    script: 'dist/server.js',
    autorestart: true,
    watch: false,
    env: {
      NODE_ENV: 'production',
    },
  }],
};

To start the service run the folowing lines:

pm2 start ecosystem.config.js
pm2 save

Now the accounts microservice is running as system service.

Configure Nginx web server

To allow access the service from external,you must configure a new virtual host in the Nginx server:

nano /etc/nginx/sites-availables/api.report.com

With the following code:

upstream mod-report-api {
  server localhost:8080;
}

server {
  listen 80;
  listen [::]:80;
  server_name api.report.com;

  location / {
    proxy_pass http://mod-report-api/;
    proxy_http_version 1.1;
    proxy_cache_bypass $http_upgrade;
    proxy_read_timeout 600s;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection 'upgrade';
    proxy_set_header Host $host;
    proxy_set_header X-Caller-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header X-Forwarded-Proto $scheme;
  }
}

And then enable the virtual host:

ln -s /etc/nginx/sites-available/api.report.com /etc/nginx/sites-enabled/api.report.com

To allow secure access to the service, use Let's Encrypt certificates. Certificates can be installed with the certbot tool:

certbot --nginx -d api.report.com

Now you can restart the Nginx server and test the microservice.
