It turns out that because @shopify/eslint-plugin, the project that this project was forked from, relies on several other plugins like eslint-plugin-import, ESLint attempts to require those plugins at runtime and can't find them because they aren't listed as dependencies, and so aren't installed.

In a nutshell, unless all those other plugins are also bundled together and their reference as plugins in each configuration removed, it's not possible for this project to be ported to a single file output with zero dependencies.

So, do not use this project, it does not work. Install @shopify/eslint-plugin instead and try not to think about the extra dependencies that come with it. I'll still put this in a public repo for posterity.

Zero-dependency ESLint plugin for Shopify's JavaScript style guide.

Includes only React and TypeScript plugins.

1. npm install -D eslint
2. npm install -D eslint-plugin-shopify-zero
3. Extend in .eslintrc:

{
  "extends": [
    "plugin:eslint-plugin-shopify-zero/typescript",
    "plugin:eslint-plugin-shopify-zero/react"
  ]
}
