An ESLint rule which enforces ordering of object keys based on T-shirt sizes. Useful for T-shirt size-based values for design systems, etc.

• Keys which follow what I call "base sizes", meaning S, M, L.
• Keys which prefix these base sizes with the character x.

yarn add -D eslint-plugin-tshirt-sizes

Add tshirt-sizes to the plugins section of your .eslintrc configuration file. You can omit the eslint-plugin- prefix:

{
  "plugins": ["tshirt-sizes"]
}

Since this plugin is intended for very specific use cases, it is best to set the rule via configuration comments for blocks where you define an object containing T-shirt sizes as keys.

/* eslint tshirt-sizes/tshirt-sizes: "error" */
const softDrinkSizes = {
  s: 1,
  l: 3, // ERR: Expected object keys to be in ascending T-shirt size order. 'l' should be before 'm'.
  m: 2,
};

/* eslint sort-keys: ["error"] */

/ *eslint sort-keys: ["error", "desc"] */

• Add support for numerical prefixes like 2xl, 3xs
