This video is basically just me messing around with using react in a rails app. There’s a lot of stuff in here on the react side that could be done better. Some of the components could be dumb/presentational components. A lot of variable naming on the fly is done pretty willy-nilly (camelCasing vs underscoring, use of const vs let, etc). Search results could be it’s own component. Etc, etc.

    At 22:30, if on Windows, need to run "ruby .binwebpack-dev-server"  instead of ".binwebpack-dev-server"

    Awesome tutorial! Thank you very much! Really enjoyed all of your videos, please make more. I created this app by your guidance and i have few questions:
    1. At 40:10 I dont really understand the point of construction […data.data.currencies] when you could just write data.data.currencies. Why complicate?
    2. Why do you use filter instead of find at 47:10? If you use find you dont need to get first item from result because you wont recieve an array.
    Thank you!

    These tutorials are excellent. Its really hard to find current Rails tutorials, YouTube, Udemy, Lynda all old out of date. You're making great videos. It would be fantastic if you could continue to do so. Much appreciated. 👍

    Just a tip guys, if you use arrow functions instead of regular JS functions you don't need to do any bindings in the constructor because in ES6 it infers that "this" is pointing to the object itself 😉

    Why do we make a POST request for the search?
