Clone the repo:

git clone https://github.com/BarryFoye/demo_app_njs.git

Change to the app directory:

cd demo_app_njs

Run the install dependencies script:

npm install

Then using 3 separate terminals started from the demo_app_njs directory and in the following order:

Terminal 1:

cd hidden_server

node index.js

When the hidden server starts you should see:

> Ready on http://localhost:3100

Terminal 2:

cd gateway_server

node index.js

Once you start the gateway server you should see a:

200

And if you check the hidden server (terminal 1 if you followed this guide), it should now have something like:

> Ready on http://localhost:3100
{"message":"/setCount?count=0","level":"info"}
{"message":"/incremented","level":"info"}

Terminal 3:

cd http_server

node index.js

Finally starting the http server you'll see:

> HTTP_server ready on http://localhost:8080

Open a browser on: http://localhost:8080
