🧹Detecting unused classes

There is an ESLint plugin that detects unused classes:

Usage

1. Add the dependency:

yarn add --dev eslint-plugin-tss-unused-classes

1. Enable it in you ESLint config

Case 1: You are in a create-react-app project: Edit your package.json:

{
  //...
  "eslintConfig": {
    "plugins": [
      //...
      "tss-unused-classes"
    ],
    "rules": {
      "tss-unused-classes/unused-classes": "warn"
    }
  },
  //...
}

Example projet

Case 2: You have installed ESLint manually: Edit your .eslintrc.js file:

module.exports = {
  // ...
  plugins: [
    // ...
    'tss-unused-classes'
  ],
  rules: {
    // ...
    'tss-unused-classes/unused-classes': 'warn'
  }
}

Example project

Disabling warnings

In case of false positive, disabling the warning:

• For a line: // eslint-disable-next-line tss-unused-classes/unused-classes

• For the entire file: // eslint-disable-next-line tss-unused-classes/unused-classes
