Description

DEVELOPER TO DEVELOPER FAST TRACK APPROACH

Learn how to:

  • Create the Native App UI and Add to Homescreen facility.

  • Use Service Workers, Cache API and caching strategies.

  • Use IndexedDB to store data and create template files to render data stored in the browser's own database - IndexedDB.

  • Access BackgroundSync so that form data is stored when offline and posted automatically when back online, even if the browser is closed.

  • Send Notifications using the Notifications API.

With the download of all lessons from the start, you will have you own PWA that you can customise. The functionality is very powerful yet the projects itself is kept basic so that you have an easy to modify boiler plate.

There is also an online version of the project so that you can see it deployed in the wild.
