Objectives

Deploy Angular Client on Nginx remote server:

• Normal deployment ->

  

• Sub-folder deployment ->

  

How to achieve it?

Start with production build ng build --prod.
-> Then copy output folder (dist/ by default) to Nginx server.

What are Production --prod optimizations?

• Ahead-of-Time (AOT) Compilation: pre-compiles Angular component templates.
• Production mode: deploys the production environment which enables production mode.
• Bundling: concatenates your many application and library files into a few bundles.
• Minification: removes excess whitespace, comments, and optional tokens.
• Uglification: rewrites code to use short, cryptic variable and function names.
• Dead code elimination: removes unreferenced modules and much unused code.

If the app uses the Angular router, When asked for a file that it does not have, Nginx server will return 404 – Not Found error.
-> Configure 404 error on the server to redirect requests for missing files to index.html:

try_files $uri $uri/ /index.html;

With sub-folder deployment, we re-build our sourcecoded with --base-href option:

ng build --prod --base-href "/grokonez/demo/"

– The HTML base href="..." specifies a base path for resolving relative URLs to assets such as images, scripts, and style sheets.

Then re-upload output(dist/ by default) to sub-folder of Nginx server:

Practice

Sourcecode for deployment at: link

Start Vultr Hosting Server

Follow the link to Login to Vultr Hosting.

– Create a small server grokonez-angular-deploy such as:

Install Nginx Server

– Use Putty, login to above server grokonez-angular-deploy:

– Install Nginx server by cmd:

sudo apt-get update
sudo apt-get install nginx

– Check your Nginx server: systemctl status nginx

Build Angular Client

– Build Production for Angular Client: ng build --prod

– Output is dist folder:

Deploy Angular Client on Nginx Server

– Use scp to copy building files from local to remote server:

– Restart Nginx server by cmd sudo service nginx restart;

-> Check results:

– Press SignUp button, got 404 Error:

– Press a link on Browser URL, got Error 404 ->

Configure 404 Error Redirect

Open nginx configuration: sudo nano /etc/nginx/sites-available/default

Redirect 404 error to index.html file by try_files:

try_files $uri $uri/ /index.html;

-> Details:

server {
	listen 80 default_server;
	listen [::]:80 default_server;

	root /var/www/html;

	index index.html index.htm index.nginx-debian.html;

	server_name _;

	location / {
			# First attempt to serve request as file, then
			# as directory, then fall back to displaying a 404.
			# try_files $uri $uri/ =404;
			try_files $uri $uri/ /index.html;
	}
}

– Restart Nginx server by cmd sudo service nginx restart
– Press SignUp button, index.html is redirected:

Deploy in Sub Folder

Rebuid Angular sourcecode with --base-href as below:

ng build --prod --base-href "/grokonez/demo/"

– Change 404 error redirect to /grokonez/demo/index.html file with try_files as below:

try_files $uri $uri/ /grokonez/demo/index.html;

– Restart Nginx server by cmd sudo service nginx restart

-> results:
