An Ext JS-based, Progressive Web Application

PWA

A demo of the Progressive Web App support in Ext JS 6.5 and Sencha Cmd 6.5.

To run

You will need to download Sencha Ext JS. We recommend extracting Ext JS into a "sencha-sdks" folder in your home directory.

Once Ext JS is extracted, run these commands:

cd client
sencha app install ~/sencha-sdks
sencha app build --dev
cd ../server
npm install
npm start

On Windows the "~" part of the path will be replaced by something like "C:\Users\Me".

You should now be able to point your browser to http://localhost:8082/.

Run Production Build

To run a production build, run these commands:

cd client
sencha app build
cd ../server
NODE_ENV=production npm start

This will run a production build and start the server with a path to the production build. You should now be able to point your browser to http://localhost:8082/.

HTTPS

When the node server is started, it will check if there are any SSL certificates in the certs directory. If not, a non-secure only server will be started. If there is, it will start both a non-secure and a secure server. You can generate self-signed localhost certificates by running:

cd server
npm run ssl

This will prompt you a few questions, you can accept the defaults except for the Common Name prompt. For this prompt, enter localhost. Once completed, there will be a server.crt and server.key in the certs directory. Now when you run npm start, it will detect these and start both servers. You can then point your browser to the non-secure or secure server.

Note: Self signed certificates are not trusted and should not be used in production. The browser will warn you of this and you must opt into allowing the self signed certificate.
