Web App Manifest

Web manifest consists of the JSON file and contains mainly about the web application, for instance, the name of the application, the icons used, and them colors. It indeed serves the purpose of providing the PWA with a native app look and feel.

HTTPS Implementation

The web app should always be served over HTTPS for PWA to make it secure and have good speed. He/she has ensured that all the information passed between the user and the server is secure and well protected.

Testing and Deployment

Like any other form of web application development, testing is an essential stage when developing Progressive Web Apps. It entails testing for operability, user-friendliness, and functionality when there is no network connection. After testing, PWA can be deployed directly to serve in real servers.

Case Studies of Successful Progressive Web Apps
