Package description

What is @typescript-eslint/eslint-plugin?

The @typescript-eslint/eslint-plugin package is an ESLint plugin that contains a set of ESLint rules that are specifically designed for TypeScript code. It helps in identifying and reporting on patterns found in TypeScript code, and it can be used to enforce a wide range of coding standards and conventions.

What are @typescript-eslint/eslint-plugin's main functionalities?

Type-aware linting

This feature allows for rules that require type information. For example, the 'strict-boolean-expressions' rule ensures that boolean expressions are clear and error-free by considering the types involved in the expression.

/* eslint @typescript-eslint/strict-boolean-expressions: 'error' */
function isTruthy(value: any): boolean {
  return Boolean(value);
}

Code style enforcement

Enforces naming conventions for everything from variables to type parameters. This example enforces camelCase naming for variables.

/* eslint @typescript-eslint/naming-convention: ['error', { 'selector': 'variable', 'format': ['camelCase'] }] */
let myVariable = 1;

Accessibility checks

This feature requires functions and methods to explicitly define their return type to improve code readability and maintainability.

/* eslint @typescript-eslint/explicit-function-return-type: 'warn' */
function add(x: number, y: number) {
  return x + y;
}
