Develop a simple demo Progressive Web App - Step 1

1. Develop a simple demo & live (not local) version of Progressive Web App. Details: i) Add an "app manifest file": to manually install on Home screen ii) Add a "Service Workers" file: to cache entire the demo page so that it can work offline first. - Content of the files should be only enough for the PWA appears like a native app and produces no errors. - This step we do not change files on the server after caching to test the app. 2. Requirements - Pass tests: real iPhone 7 & iOS 14 and an emulated Android Device - Must be familiar with trusted resources such as W3C, Google Developers, Mozilla Developer Network, Progressive Web Apps on Windows. - Experienced with Git for both version control and collaboration - We will use framework like Workbox, PWA Builder etc., but you should be at the level of knowing how to code from scratch 3. Styles i. Working: we will start slowly with very small tasks to get to know each other, then gradually speed up the development ii. Coding convention: consistent 4. Notes - The demo version is to prepare for the real PWA later. The reasons we have a demo version are catching up with fast pace of this tech field and concluding the features of the real one. - All contents for the demo version are samples - You must test the demo PWA on your local desktop and emulated device - It does not matter where you host the demo app. You can choose to use our ready demo https site - You must give us credential to directly access sample database to double check (later) - What we don't do in this project: + Native device features + Background sync: temporarily store sending data requests on clients when offline + Web push notifications - Read the attached documents, Microsoft OneNote, for the full list of tasks of this demo project * PWA is relatively new therefore this job is negotiable
