Installation

:warning: This tutorial implies that typescript-eslint is installed and linting with type information is set up

Note: If you installed ESLint globally then you must also install eslint-plugin-typescript-inheritance globally.

Usage

Add typescript-inheritance to the plugins section. You can omit the eslint-plugin- prefix:

{
  "plugins": ["typescript-inheritance"]
}

Then enable all rules with recommended configuration:

{
  "extends": ["plugin:typescript-inheritance/recommended"]
}

Or configure the rules you want to use under the rules section:

{
  "rules": {
    "typescript-inheritance/no-class-inheritance": ["error"]
  }
}
