Tunneling

The point of tunneling is to serve one of your local port (here localhost:5000) on a url (such as random.yourdomain.com)

Why ?

If you want to mimic the behavior of you app when accessed from the outside

Local Tunneling

Advantage : easy Draw back : not accessible form the outside

The instructions here are written for a macOS 10.13.3

Step One : serve your app localhost:80

1. Download nginx

brew install nginx

To stop nginx, run

nginx -s stop

2. Configure nginx

server {
        listen       80;
        server_name  anna.anna-livia.com;

        location / {
            proxy_pass http://localhost:5000;
            proxy_http_version 1.1;
            proxy_set_header Host $host;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        }

3. Open your browser to localhost:80

Step Two : Serve localhost when requesting random.yourdomain.com

1. Open /etc/hosts

sudo vim etc/hosts

2. Add the domain

127.0.0.1	random.yourdomain.com

3. Access random.yourdomain.com from your browser
