The import-fresh module in JavaScript offers an opportunity to import another module while bypassing the cache. This can be extremely useful, particularly when testing, as it allows users to freshly import a module without any residual cache variables or data.
The implementation and use of the import-fresh module is very simple. After installing the package using npm install import-fresh, you can require it in your script with const importFresh = require('import-fresh');. Here's how it works in practice:
// In your foo.js file, you might have something like this:
let i = 0;
module.exports = () => ++i;
// Then in your main file:
const importFresh = require('import-fresh');
require('./foo')(); //=> 1
require('./foo')(); //=> 2
importFresh('./foo')(); //=> 1
importFresh('./foo')(); //=> 1
As the above example demonstrates, the same module, when imported normally, maintains the count (i) in the cache. So, every time the module exports function is called, the count increases. However, when the same module is imported using the import-fresh module, the cache is bypassed, resulting in the count resetting to its original value each time the function is called.
The import-fresh documentation and further details concerning its functionality and usage can be found on its official GitHub page here. This page also discusses how import-fresh can be beneficial for enterprise-level applications, through a Tidelift Subscription, which provides commercial support and maintenance for this and thousands of other open-source dependencies.
