Front End Development for Back End Developers - UberConf 2017
2 likes1,433 views
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 frontend development (npm, yarn, Gulp, Webpack, Yeoman) and learn the basics of HTML, CSS, and JavaScript. This presentation dives into the intricacies of Bootstrap, Material Design, ES6, and TypeScript. Finally, after getting you up to speed with all this new tech, I'll show how it can all be found and integrated through the fine and dandy JHipster project.
