@walgreenshealth/test-eslint-plugin

@walgreenshealth/eslint-plugin

This plugin is mostly a set of configurations for ESLint. It consolidates a bunch of open source plugins and has a lot of rules.

It includes the following configs:

• walgreenshealth/recommended
• @walgreenshealth/typescript
• @walgreenshealth/storybook
• @walgreenshealth/jest

And the following custom rules:

• @walgreenshealth/custom-element-name makes sure name of a custom element declared in @customElement(walgreenshealth-whatever) matches its file name
• @walgreenshealth/element-export-name makes sure the element's class name matches the file name

Here's a simple example of how to use it (.eslint.config.json):

{
  "plugins": ["@walgreenshealth/eslint-plugin"],
  "extends": ["plugin:@walgreenshealth/recommended"],
  "overrides": [
    {
      files: ["*.stories.js"],

      extends: [
        "plugin:@walgreenshealth/recommended",
        "plugin:@walgreenshealth/storybook",
      ],
    },
    {
      files: ["*.test.js"],

      extends: [
        "plugin:@walgreenshealth/recommended",
        "plugin:@walgreenshealth/storybook",
      ],
    }
};
