Experience

  • Underscore Templating for Atom (Development)
    https://github.com/dborstelmann/atom-underscore

    I realized there was no syntax highlighter for Underscore templates in Atom, so I decided to build one! I developed it using Atom's easy extensibility process. Now developers using Underscore's templating system can more efficiently develop HTML files with data.
