III. Setup and test it locally

We provide source code with 4 folders, check below and use in the app accordingly

user web frontend (front office)
admin backend (back office), admin control panel
api api of the app
config-example
- env product environment example config
- nginx nginx config example

1. API

Ensure node v12.x, MongoDB, Redis server, FFMPEG and yarn are running
CD to your API folder
Run yarn to install nodeJS dependencies. Make sure your NODE_ENV is not production or run yarn install --production=false to install both dependencies and devDependencies

$ yarn
yarn install v1.16.0
[1/4] 🔍  Resolving packages...
[2/4] 🚚  Fetching packages...
[3/4] 🔗  Linking dependencies...

Create new .env from config-example > env > api.env file in the root dir

Open file .env and change config accordingly. The config looks like below

NODE_ENV=production
# Change with your custom HTTP port
HTTP_PORT=8080
# Change secret with your key
TOKEN_SECRET=1213456

REDIS_HOST=127.0.0.1
REDIS_PORT=6379
REDIS_DB=0
REDIS_PREFIX=bee_queue

# Change mongo uri correctly. Read more about connection string here https://docs.mongodb.com/manual/reference/connection-string/
MONGO_URI=mongodb://localhost/xcams-v3
# Use for seed and some features, change with your domain without http(s)://
DOMAIN=yourdomain.com

BASE_URL=http://localhost:9000
USER_URL=http://yourdomain.com

Open browsers and run http://localhost:8080 it should show success message or Hello World!

2. User Frontend Web

CD to user folder
Run yarn to install nodeJS dependencies. Make sure your NODE_ENV is not production or run yarn install --production=false to install both dependencies and devDependencies

$ yarn
yarn install v1.16.0
[1/4] 🔍  Resolving packages...
[2/4] 🚚  Fetching packages...
[3/4] 🔗  Linking dependencies...

Create file .env from config-example > env > user.env and update your config accordingly. Config looks like below

# http port
PORT=8081

NEXT_PUBLIC_DEBUG=false

# api endpoint we can call in the server side, if single server it can run to api:port without proxy
API_ENDPOINT=http://localhost:8080
NEXT_PUBLIC_API_ENDPOINT=http://localhost:8080
NEXT_PUBLIC_SOCKET_ENDPOINT=http://localhost:8080

# upload file
NEXT_PUBLIC_MAX_VIDEO_BITRATE_KBPS=900
NEXT_PUBLIC_IMAGE_ACCPET=.jpeg, .jpg, .png
NEXT_PUBLIC_MAXIMUM_SIZE_UPLOAD_AVATAR=2

Run yarn run dev to start development env

$ yarn run dev
yarn run v1.16.0
$ ts-node --project tsconfig.server.json server/index.ts
Warning: Built-in CSS support is being disabled due to custom CSS configuration being detected.
See here for more info: https://err.sh/next.js/built-in-css-disabled

> Using external babel configuration

Then you can open browser http://localhost:8081 to see the web

3. Admin

Similar Frontend web, same steps. but create .env from config-example > env > admin.env
Run yarn dev then open http://localhost:8082 to see your admin app

IV. Setup production environment with NGINX

1. API

Deploy / copy your api folder to /var/www/api.example.com
CD to /var/www/api.example.com and install nodeJS dependencies by yarn command. Setup .env file accordingly
Install pm2 (check softwares point)
Make sure you have installed nodeJS dependencies by yarn command or run yarn install --production=false to install both dependencies and devDependencies
Change port to 8080 in .env file or export HTTP_PORT=8080
In API root directory, run yarn build

$ yarn build
yarn run v1.16.0
$ rimraf dist
$ nest build && yarn copy-template
$ cp -r ./src/templates ./dist/templates
✨  Done in 22.62s

Testing by run command yarn start:prod or node dist/main.js

$ yarn start
yarn run v1.16.0
$ node dist/main
[Nest] 60205   - 08/03/2020, 2:56:11 PM   [NestFactory] Starting Nest application...

Run export NODE_ENV=production
Run pm2 start dist/main.js --name=api to run API under background

Or run pm2 start yarn --interpreter bash --name xcams-v3-api -- start:prod to run application under port 8080

Note: If have error when starting with Pm2, please try to start without interpreter.

pm2 start yarn --name xcams-v3-api -- start:prod

2. Frontend Web

Deploy / copy your user folder to /var/www/example.com
CD to /var/www/example.com and install nodeJS dependencies by yarn command. Setup .env file accordingly
Install pm2 (check softwares point)
Make sure you have installed nodeJS dependencies and devDependencies by yarn command or run yarn install --production=false to install both dependencies and devDependencies
Run yarn build

$ yarn build

4. Setup nginx

Api
- Let say our frontend code is in /var/www/api.example.com folder and api is running under port 8080, add new file in /etc/nginx/sites-enabled/api.example.com and content as bellow
- You have to change with our server name and source code path

server {
    listen 80 ;
	root /var/www/api.example.com/public;
	
	index index.html;
    server_name api.example.com;
    gzip on;
    gzip_proxied any;
    gzip_comp_level 4;
    gzip_types text/css application/javascript image/svg+xml;

    sendfile on;
    tcp_nopush on;
    tcp_nodelay on;
    keepalive_timeout 65;
    types_hash_max_size 2048;
    sendfile_max_chunk 512;
    client_max_body_size 2000M;
    
    # tuning performance for log request
    access_log off;
    error_log off;

    location / {
      try_files $uri @app;
    }

	location @app {
      proxy_set_header   X-Forwarded-For $remote_addr;
      proxy_set_header   Host $http_host;
      proxy_pass         http://localhost:8080;
      proxy_set_header Upgrade $http_upgrade;
      proxy_set_header Connection 'upgrade';
      proxy_cache_bypass $http_upgrade;
      
      # WebSocket support
      proxy_connect_timeout 7d;
      proxy_send_timeout 7d;
      proxy_read_timeout 7d;
	}
	
	location /.well-known {
      alias /var/www/api.example.com/public/.well-known;
    }
	
	location /videos/protected/ {
	  auth_request /authvideo;
	  root /var/www/api.example.com/public/;
	}

	location = /authvideo {
	  internal;
          set $query '';
          if ($request_uri ~* "[^\?]+\?(.*)$") {
              set $query $1;
          }
          proxy_pass http://localhost:8080/user/performer-assets/videos/auth/check?$query;
          proxy_pass_request_body   off;
          proxy_set_header Content-Length "";
	}
	location /photos/protected/ {
	  auth_request /authphoto;
	  root /var/www/api.example.com/public/;
	}

	location = /authphoto {
	  internal;
          set $query '';
          if ($request_uri ~* "[^\?]+\?(.*)$") {
              set $query $1;
          }
          proxy_pass http://localhost:8080/performer/performer-assets/photos/auth/check?$query;
          proxy_pass_request_body   off;
          proxy_set_header Content-Length "";
	}
}

Frontend
- Let say our frontend code is in /var/www/example.com folder and Frontend app is running under port 8081, add new file in /etc/nginx/sites-enabled/example.com and content as bellow
- You have to change with our server name and source code path

server {
    listen 80;
	server_name example.com;

	root /var/www/example.com/public;

    gzip on;
    gzip_proxied any;
    gzip_comp_level 4;
    gzip_types text/css application/javascript image/svg+xml;

    sendfile on;
    tcp_nopush on;
    tcp_nodelay on;
    keepalive_timeout 65;
    types_hash_max_size 2048;
    sendfile_max_chunk 512;
    
    # tuning performance for log request
    access_log off;
    error_log off;

    location / {
      try_files $uri @app;
    }

	location @app {
        proxy_pass http://localhost:8081;
        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;
        proxy_redirect        off;
        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      Proxy "";
    }
    
    location /.well-known {
        alias /var/www/example.com/public/.well-known;
    }

    location /_next/static/ {
        alias /var/www/example.com/dist/.next/static/$1;
        access_log off;
        expires max;
    }

    location /static/ {
        alias /var/www/example.com/public/static/$1;
        expires max;
        autoindex off;
    }
}

Note

if have dist folder after build, the location /_next/static/ should be alias /var/www/example.com/dist/.next/static/$1;
If don’t have dist folder, check and update location /_next/static/ toe alias /var/www/example.com/.next/static/$1;

Admin
- Let say our frontend code is in /var/www/admin.example.com folder and Frontend app is running under port 8082, add new file in /etc/nginx/sites-enabled/admin.example.com and content as bellow
- You have to change with our server name and source code path

server {
    listen 80;
	server_name admin.example.com;
	root /var/www/admin.example.com/public;

    gzip on;
    gzip_proxied any;
    gzip_comp_level 4;
    gzip_types text/css application/javascript image/svg+xml;

    sendfile on;
    tcp_nopush on;
    tcp_nodelay on;
    keepalive_timeout 65;
    types_hash_max_size 2048;
    sendfile_max_chunk 512;
    
    # tuning performance for log request
    access_log off;
    error_log off;

    location / {
      try_files $uri @app;
    }

	location @app {
        proxy_set_header   X-Forwarded-For $remote_addr;
        proxy_set_header   Host $http_host;
        proxy_pass         http://localhost:8082;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        proxy_cache_bypass $http_upgrade;
    }
    
    location /.well-known {
        alias /var/www/admin.example.com/public/.well-known;
    }

    location /_next/static/ {
        alias /var/www/admin.example.com/.next/static/$1;
        access_log off;
        expires max;
    }

    location /static/ {
        alias /var/www/admin.example.com/public/static/$1;
        expires max;
        autoindex off;
    }
}

Note

if have dist folder after build, the location /_next/static/ should be alias /var/www/admin.example.com/dist/.next/static/$1;
If don’t have dist folder, check and update location /_next/static/ toe alias /var/www/example.com/.next/static/$1;

Testing
- Open browser and access: http://yourdomain.com to access web frontend
- Open browser and access: http://admin.yourdomain.com to access web admin

5. Check applications are running under pm2

Run pm2 ls to see your applications
Run pm2 stop [id] to stop app or pm2 reload [id] to reload
Run applications in start up by pm2 startup then pm2 save

6. Set up nginx with https

Check here to setup https with nginx
Setup https with Certbot nginx

7. Migration

From API root directory, open .env and edit DOMAIN value to your domain (without protocol eg http://example.com ). Run yarn migrate (if command not found, try to check package.json file and see if have script:migrate command instead) to seed default values for settings and users
- Default admin: admin@[yourdomain] with domain is in .env file
- Default password: adminadmin
- If admin password is wrong, you can run node script reset-admin-pw to reset it to adminadmin
You can change default values in src > migrations folder
