Import a module while bypassing the cache
Useful for testing purposes when you need to freshly import a module.
npm install import-fresh
// foo.js
let count = 0;
export default function increment() {
count += 1;
return count;
}
import createImportFresh from 'import-fresh';
const importFresh = createImportFresh(import.meta.url);
const {default: increment} = await importFresh('./foo.js');
increment();
//=> 1
increment();
//=> 2
const {default: freshIncrement} = await importFresh('./foo.js');
freshIncrement();
//=> 1
Returns an importFresh function bound to parentURL.
parentURL must be a valid hierarchical URL string (for example import.meta.url) or a URL instance.
Type: object
The options are process-global. Every call in the same process must use the same skipNodeModules value.
Type: boolean
Default: false
When true, modules inside node_modules directories are not cache-busted. This means that dependencies from npm packages will share state across fresh imports, which can be useful when you only want to freshly import your own code.
The function returned by createImportFresh.
Type: object
Type: object
Import attributes passed to import(). Each value must be a string. JSON modules are automatically imported with {type: 'json'} when the specifier ends with .json.
Intended for development usage only. Repeated calls grow the ESM module cache because each call uses a unique cache-busting URL. This is an unavoidable “memory leak” and not considered a vulnerability.
