This repository contains the source code for the Building Modern Web Applications With Spring Boot and Vaadin.

Live demo: http://crm.demo.vaadin.com

There are two ways to run the application: using mvn or by running the Application class directly from your IDE.

• The main branch contains the source code for the latest Vaadin release
• The v14 branch contains the source code for Vaadin 14

You can find a text version of the tutorial in the Vaadin Documentation.

Follow any install instructions from the mkcert docs: http://github.com/FiloSottile/mkcert

Open an elevated (e.g. Run as Administrator) command line Run mkcert -install You should see something similar to the following:

- Using the local CA at “C:\Users\[Username]\AppData\Local\mkcert” ✨
- The local CA is now installed in the system trust store! ⚡️
- The local CA is now installed in Java’s trust store! ☕

# create the directory
mkdir -p ~/.config/spring-boot

# generate a certificate in pkcs12 format
mkcert -pkcs12 -p12-file ~/.config/spring-boot/local-tls.p12 {IP-address}

Add to application.properties

server.ssl.key-store=${user.home}/.config/spring-boot/local-tls.p12

Go to chrome://flags and add http://{IP-address}:port to Insecure origins treated as secure and enable the experiment.

Navigate to self signed http app and test webpush on mobile.

generate crt from the custom pem root certificate
openssl x509 -inform PEM -outform DM -in rootCA.pem -out local.crt

install the crt on the android as user certificate.

For ipad the minimum requirement is iOS 16.4 which got Web Push support.

To install the local certificate download it for the network and install after it has downloaded.

Then turn on SSL/TLS trust for the certificate, - go to Settings > General > About > Certificate Trust Settings - Under "Enable full trust for root certificates," turn on trust for the certificate.

Then enable the required advanced features for Safari - go to Settings > Safari > Advanced > Experimental Features - enable Notifications and Push API

Open the site from the home screen to be able to make the push subscription.

Note! The subject needs to be the server address or a mailto: when using Safari and the apple web push server.
