# import-fresh

> Import a module while bypassing the [cache](https://nodejs.org/api/modules.html#modules_caching)

Useful for testing purposes when you need to freshly import a module.

## ESM

For ESM, you can use this snippet:

```js

const importFresh = moduleName => import(`${moduleName}?${Date.now()}`);

const {default: foo} = await importFresh('foo');

```

**This snippet causes a memory leak, so only use it for short-lived tests.**

## Install

```

$ npm install import-fresh

```

## Usage

```js

// foo.js

let i = 0;

module.exports = () => ++i;

```

```js

const importFresh = require('import-fresh');

require('./foo')();

//=> 1

require('./foo')();

//=> 2

importFresh('./foo')();

//=> 1

importFresh('./foo')();

//=> 1

```
