Designed to be modular, and to have everything you need without anything extra. React and TypeScript are optional, but you wouldn't need a boilerplate if you weren't using at least one of them.
Assuming you're looking at the actual barebones repo and not at a finished plugin where someone didn't write you a readme, here's how to get started.
First, do search-replaces. Case-sensitive.
- myEmptyPlugin -> yourEmptyPlugin
- NS -> yourNameSpace
- myemptyplugin -> yourtextdomain
Then, just install the dependencies and start working.
npm install
Dev: npm run start
Build for prod: npm run build
This barebones config was stripped from https://github.com/libreform/libreform. This is mainly for my use, but if it's of use to someone else, great. Before you go changing things, there's probably a reason why they are the way they are.
To remove React, just remove it from your script dependencies when you enquque them. It's not included in your build to begin with.
To "remove" TypeScript, simply create .js equivalents of admin.ts and frontend.ts, and update webpack config paths to match. I encourage you to try TS though. You can always use any as type if you're stuck and need to get shit done.
Should work out of the box.
