Preface

Below are the steps I took to install ffmpeg, ffmpegthumbnailer, and heroku to use with carrierwave-video and carrierwave-video-thumbnailer gems on my heroku app. I found there was no documentation to do exactly this, so I hope this is helpful for other people (and will save them the countless hours it took me to finally get it to work)

• carrierwave-video gem: https://github.com/rheaton/carrierwave-video
• carrierwave-video-thumbnailer gem: https://github.com/evrone/carrierwave-video-thumbnailer

These are the libraries you will end up installing to get all of this to work.

Moving to ES6 from CoffeeScript

I fell in love with CoffeeScript a couple of years ago. Javascript has always seemed something of an interesting curiosity to me and I was happy to see the meteoric rise of Node.js, but coming from a background of Python I really preferred a cleaner syntax.

In any fast moving community it is inevitable that things will change, and so today we see a big shift toward ES6, the new version of Javascript. It incorporates a handful of the nicer features from CoffeeScript and is usable today through tools like Babel. Here are some of my thoughts and issues on moving away from CoffeeScript in favor of ES6.

While reading I suggest keeping open a tab to Babel's learning ES6 page. The examples there are great.

Punctuation

Holy punctuation, Batman! Say goodbye to your whitespace and hello to parenthesis, curly braces, and semicolons again. Even with the advanced ES6 syntax you'll find yourself writing a lot more punctuatio
