# 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
|
|
|
|
```sh
|
|
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
|
|
```
