{NK} Chat Application for IOPA and {NK} NodeKit

Build Status IOPA NodeKit


Open Source Chat App

Running the application locally

The application uses Node.js and npm, so you must download and install them as part of the following steps.

  1. Go to the project folder in a terminal and run the npm install command.
  2. Start the application by running npm start.
  3. Open http://localhost:3000 to see the running application.

About the Sample

The sample includes the lightweight IOPA fabric and includes

  • IOPA server to run on both Node and NodeKit without application changes
  • IOPA router to demonstrate URL routing
  • IOPA static to server up static files (e.g., css, js, etc.)
  • IOPA templates engine including handlebars for splitting a large single page view into multiple smaller components
  • IOPA connect to use vanilla Node HTTP transport

The sample is a fully fledged chat application using a Firebase back end. No other dependencies other than the IOPA stack which is installed automatically using npm.

  • No database or other transport engines, using Google Firebase for simplicity of demonstrating the sample
  • No front-end framework (like React, or Angular), just pure DOM JQuery, again just to demonstrate the sample
  • Handlebars used as the template engine, others could easily be sustituted

The application was written by OffGridNetworks to demonstrate ease of use in creating Node applications using the IOPA stack instead of Express, and to provide a high fidelity sample to encourage a high quality ecosystem for both IOPA servers and for {NK} NodeKit applications. It runs extremely well on NodeKit across OS X, iOS, Windows, Android and is responsive to different device sizes.
