Offline web application

What is it

This project is a minimal webapp which works offline. To allow this, it uses Service Worker and Dexie (an IndexedDB wrapper).

Technologies used :

• NPM
• Webpack
• AngularJS
• Dexie (IndexedDB)
• Service Worker

How to build it

Get the dependencies with NPM :

npm install

And then run Webpack (see package.json scripts) :

npm run build 

How to deploy it

First of all, you will need an HTTPS server (because the Service Worker need it to works), so we need a SSL certificate, you can generate one with the following command line :

openssl req -new -x509 -keyout key.pkey -out server.cert -days 365 -nodes

Install the http-server npm package to use the deploy.sh script :

npm install http-server -g

And to finish, run the deploy.sh script :

./deploy.sh

The webapp is now available at https://127.0.0.1:8443.

Note: Even when you trust your self signed SSL certificate (in Keychain Access on macOS for example), service worker registration fails in Chrome with the error net::ERR_CERT_COMMON_NAME_INVALID (in JS Console). It works in Firefox but if you want to use it in Chrome, you can take a loot at this thread

Note

The country list countries.json is coming from the country-list project.
