eslint-plugin-ts-export-naming-convention

An ESLint plugin to enforce naming conventions for TypeScript exports.

Getting Started

1. Install dependencies

• typescript-eslint: enables ESLint and Prettier to support TypeScript
• eslint-plugin-ts-export-naming-conventions

yarn add -D \
  eslint \
  typescript \
  @typescript-eslint/eslint-plugin \
  @typescript-eslint/parser \
  eslint-plugin-ts-export-naming-convention

2. Add the plugin to your ESLint config

// .eslintrc.cjs
module.exports = {
  plugins: [
    'plugin:@typescript-eslint/recommended', // <-- more configurations found on https://typescript-eslint.io/linting/configs#recommended-configurations
    'plugin:ts-export-export-naming-convention/recommended', // <-- apply the plugin
  ],
  parser: '@typescript-eslint/parser',
};

Rules

Interfaces & Type Aliases

• Interfaces & type aliases should be in format of PascalCase

// ✅ PascalCase
export interface IProps {}
export type TProps = {};

// ❌ camelCase
export interface iProps {}
export type tProps = {};

• Exported interface should be prefixed with I

// ✅ `IProps` interface is exported
export interface IProps {}

// ❌ `Props` interface is exported
export interface Props {}

// ✅ `AnotherProps` interface is NOT exported
interface AnotherProps {}

• Exported type alias should be prefixed with T

// ✅ `TProps` type alias is exported
export type TProps = {};

// ❌ `Props` type alias is exported
export type Props = {};

// ✅ `AnotherProps` type alias is NOT exported
type AnotherProps = {};
