Front Ends for Back End Developers - Spring IO 2017

YouTube: https://www.youtube.com/watch?v=HnX09pdxEQI

Are you a backend developer that’s being pushed into front end development? Are you frustrated with all JavaScript frameworks and build tools you have to learn to be a good UI developer? If so, this session is for you! We’ll explore the tools of the trade for fronted development (npm, yarn, Gulp, Webpack, Yeoman) and learn the basics of HTML, CSS, and JavaScript. We’ll dive into the intricacies of Bootstrap, Material Design, ES6, and TypeScript. Finally, after getting you up to speed with all this new tech, we’ll show how it can all be found and integrated through the fine and dandy JHipster project.

And they aren't going to see him as some kind of object either. Quality destroys objectivity every time.” — Zen and the Art of Motorcycle Maintenance
