Import a module while bypassing the cache

import-fresh

Import a module while bypassing the cache

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

ESM

For ESM, you can use this snippet:

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

// foo.js
let i = 0;
module.exports = () => ++i;

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

require('./foo')();
//=> 1

require('./foo')();
//=> 2

importFresh('./foo')();
//=> 1

importFresh('./foo')();
//=> 1
