Prerequisite

• Node
• Yarn

To run the project locally in the project directory, you can run:

yarn start

Runs the app in the development mode.
Open http://localhost:3000 to view it in the browser.

The page will reload if you make edits.
You will also see any lint errors in the console.

To build the project for production

yarn run build

Builds the app for production to the build folder.
It correctly bundles React in production mode and optimizes the build for the best performance.

The build is minified and the filenames include the hashes.

To run the Production version locally you need to use a local server. Use the following command to install one:

yarn global add serve

and then use following command to start the local server

serve -s build

Open http://localhost:8000 to view it in the browser.

Reference

• React Docs
• Full Stack React

The app uses the service worker to cache the network requests, and responds with the saved data, if the network goes down. Service workers only work with production build, so make sure you build the production version. Also, to test service workers it is important to host your app on a HTTPS server, but for development sake, these also work on localhost so we can use serve to test this functionality.

Once, you have hosted the app using serve,

• open http://localhost:5000
• Wait for the Webapp to load completely, once loaded you will see a message in the console. Content is cached for offline use. ( To open console in Google Chrome on Windows and Linux press Ctrl + Shift + J, On Mac: Cmd + Option + J).
• Now, Emulate network connectivity to offline mode. (Read More on how to do it in Google Chrome.
• Now under no internet connection mode, run the app again.

#Note this service worker do not cache the request from external API's ( Caching of Google Map's API is against it's terms and conditions. )
