Get Hip with JHipster - Colorado Springs OSS Meetup April 2016

1,599 views

Published on

Building a modern web (or mobile) application requires a lot of tools, frameworks and techniques. This session shows how JHipster unites popular frameworks like AngularJS, Spring Boot and Bootstrap. Using Yeoman, a scaffolding tool for modern webapps, JHipster will generate a project that uses Java 8, SQL or NoSQL databases, Spring profiles, Maven or Gradle, Gulp.js, WebSockets and BrowserSync. It also supports a number of different authentication mechanisms: classic session-based auth, OAuth 2.0, or token-based authentication. For cloud deployments, JHipster includes out-of-the-box support for Cloud Foundry and Heroku.
