Building

Use yarn run build for building.

Building and running using Docker

Follow the instructions on Building your image and Running the image. Change the port number in both .env and Dockerfile if the webapp should be run on another port than 3000.

Running with pm2

You can run the built backend using pm2 restart templewallet-backend.json.

Upstreaming using nginx

Append these lines into server block of /etc/nginx/sites-available/default:

location /api/dapps {
  proxy_http_version 1.1;
  proxy_cache_bypass $http_upgrade;

  proxy_set_header Upgrade $http_upgrade;
  proxy_set_header Connection 'upgrade';
  proxy_set_header Host $host;
  proxy_set_header X-Real-IP $remote_addr;
  proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
  proxy_set_header X-Forwarded-Proto $scheme;

  proxy_pass http://localhost:3000;
}

location /api/exchange-rates/ {
  proxy_http_version 1.1;
  proxy_cache_bypass $http_upgrade;

  proxy_set_header Upgrade $http_upgrade;
  proxy_set_header Connection 'upgrade';
  proxy_set_header Host $host;
  proxy_set_header X-Real-IP $remote_addr;
  proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
  proxy_set_header X-Forwarded-Proto $scheme;

  proxy_pass http://localhost:3000;
}

Replace 3000 with the respective port number if the backend is listening on a different one. Restart nginx using sudo systemctl restart nginx after changes are saved.
