The developer created a home inspection app to allow home inspectors to create and manage inspections from their laptop or mobile device without internet access. The single page app was built with Angular, Express, MongoDB, and Node.js. It includes features like templates, categories, items and options to structure inspections, as well as the ability to edit lists, add new templates, and generate PDFs of completed inspections. Socket.io was used to demonstrate push notifications between devices. The source code is available on GitHub to show how it was built.
