React + Vite + SWR Progressive Web App

This project is a demonstration of how to build a Progressive Web App (PWA) with offline capabilities using React, Vite, and SWR.

Purpose

The purpose of this project is to demonstrate a basic progressive web application that is built with React, Vite, and SWR.

For caching static assets and pages for offline use, it uses vite-plugin-pwa.

For caching data for offline use, it uses the basic LocalStorage Based Persistent Cache example from SWR. The data being used in this example is time information from WorldTimeAPI.

Technologies

• React: A JavaScript library for building user interfaces.
• Vite: A build tool that aims to provide a faster and leaner development experience for modern web projects.
• SWR: A React Hooks library for remote data fetching.

Getting Started

1. Clone the repository
2. Install dependencies with yarn install
3. Start the PWA with yarn pwa (The normal development server can still be started with yarn dev, but PWA features will not be available)

Demo

You'll see two cards, one that shows the browser time (using JavaScript Date), and one that shows the time from the API. Once you have downloaded the application, you should be able to open the application even if you have no internet connection, and see the last fetched API time.

Enjoy exploring and building upon this project!
