Accio React App

My professional-self has been writing a whole lot of React components lately. I've mixed feelings about React (mostly do to it's parentage), but I'm very much enjoying the work and am happy to be writing functional code.

When I started my most recent React project I decided to not use Webpack and instead opted to use Parcel (shout out to @hjertnes for the intro!). My plan was for this to be a post about Parcel and how to use it, but in the course of sussing out what I was going to cover, I ended up writing a little script…

The script is a beautifully procedural bit of bash that instantiates a basic react starting point.

I've used Webpack before and found it to be a) overly complicated, b) a gargantuan time-suck.

I've also toyed with react-create-app and always been displeased. It works well, but is a bit limiting out of the box, and it's eject method is…terrifying?

Accio React App is my answer to react-create-app. It provides the minimal bits needed to start a React project (including react-router, sass and babel) and a basic project scaffolding. It isn't much, but I've already found it to be a helpful little thing.

Here is the script in full, it can also be found on my pastebin and as a gist hosted on GitHub.
