Overview

This app was an experiment to do some things with Node.js and Socket.io. It consists of two views, a / route and a /view route. The main view allows the user to increment or set a custom number that is then written to a text file. That new number is then updated in the main view, and Socket.io is used to push the updated number to the /view page. The view page is intended to be on a separate tab on a different monitor or viewed on another computer on the same network, since the app listens by IP address. You will need a data.txt file in the root directory of the app for it to work.

pkg is used to compile all the files to a binary for running on Mac, Windows, or Linux machines without having to install Node or other depdencies.

Running

git clone https://github.com/AntonEmery/counter-app
cd counter-app
npm install
npm start

Once the app starts your IP address should be displayed in the terminal. Open your-ip-address:7777 and your-ip-address:7777/view in the browser

Package the contents into a binary

pkg package.json

Select the approriate binary file from the three created. Be sure to place a data.txt in the same directory that binary is being installed in.

Technologies Used

• Node.js - For all the server side code and writing to the text file
• Pug - basic templating
• Socket.io - For pushing the updated number from the text file to the /view page
• pkg - Packages the app into a binary for running on various operating systems.
