Sample project Spring Boot + Server Sent Events + Angular

• install npm (Node Package Manager)
• install angular-cli via npm
• run "npm install" to download client dependencies (node_modules folder should appear)

• Build front-end (client): ng build
• Build back-end (server): mvn clean install

java -jar <path to jar>

• Run application as usual
• Execute "ng serve --proxy-config proxy.conf.json" in terminal
• Go to localhost:4200

Client deployed separately, but will use usual backend. When some changes done in IDE, angular will automatically rebuild client side and deploy it.
