Eslint plugin typescript rules

A plugin for enforcing some Javascript best practices when using Typescript as "typed" Javascript. This plugin can also be used together with Javascript to prevent the usage of Class extends.

Usage

Install eslint and the plugin npm i eslint eslint-plugin-typescript-rules --save-dev

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

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

Then configure the rules you want to use under the rules section.

{
  "rules": {
    "typescript-rules/disallow-class-extends": "error",
    "typescript-rules/disallow-abstract-class": "error",
    "typescript-rules/disallow-non-es-compatible": "error"
  }
}

Recommended

This plugin exports a recommended configuration that includes all the rules enabled.

To enable this configuration use the extends property in your .eslintrc config file:

{
  "extends": [
    "eslint:recommended",
    "plugin:typescript-rules/recommended"
  ]
}
