eslint-plugin-require-extensions v0.1.3

eslint-plugin-require-extensions

TypeScript doesn't transform extensions and doesn't enforce file extensions.

This is a simple eslint plugin that ensures that relative imports and exports have .js extensions.

Credit for the original implementation goes to johnrees. ❤️

1. Install

npm install --save-dev eslint-plugin-require-extensions

    "extends": [
