# Babel Plugin Vitest (`babel-plugin-vitest`)

This a plugin for [Babel](https://babeljs.io/) that replaces instances of `import.meta.vitest` in your code with

`undefined`.

This plugin should be put in your babel config when you are using [Vitest](https://vitest.dev/)'s

[In-Source Testing](https://vitest.dev/guide/in-source.html) feature.

## Setup

### Install

```sh

npm install --save-dev babel-plugin-vitest

```

### Babel config

`babel.config.json`

```json

{

	"plugins": [ "babel-plugin-vitest" ]

}

```

## Example

### In

`src/index.js`

```js

// the implementation

export function add(...args) {

	return args.reduce((a, b) => a + b, 0)

}

// in-source test suites

if (import.meta.vitest) {

	const { it, expect } = import.meta.vitest

	it('add', () => {

		expect(add()).toBe(0)

		expect(add(1)).toBe(1)

		expect(add(1, 2, 3)).toBe(6)

	})

}

```

### Out

`dist/index.js`

```js

// the implementation

export function add(...args) {

	return args.reduce((a, b) => a + b, 0)

}

// in-source test suites

if (undefined) {

	const { it, expect } = import.meta.vitest

	it('add', () => {

		expect(add()).toBe(0)

		expect(add(1)).toBe(1)

		expect(add(1, 2, 3)).toBe(6)

	})

}

```
