@exodus/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

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

2. Edit .eslintrc

`json
{
"extends": ["plugin:@exodus/require-extensions/recommended"],
"plugins": ["@exodus/require-extensions"]
}
`

3. Code

`js
// source.js

import Target from './target'
`

4. Lint

`shell
eslint .
`

`
source.js
1:1 error Relative imports and exports must end with .js require-extensions/require-extensions
`

5. Fix

`shell
eslint --fix .
`

`js
// source.js

import Target from './target.js'
