  # 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
  ```
