Import ES modules without cache.

Features

- Import ES modules without cache
- All dependencies are also imported without cache

Install

``bash
npm i import-without-cache
`

Usage

`ts
import { clearRequireCache, init, isSupported } from 'import-without-cache'

if (!isSupported) {
throw new Error('import-without-cache is not supported in this environment.')
}

const deregister = init({
// Optional
skipNodeModules: false,
})

const mod = await import('some-module', { with: { cache: 'no' } })

clearRequireCache() // Optional: clear CommonJS cache if needed

// or
const mod2 = await import(no-cache://some-module)

expect(mod).not.toBe(mod2) // Different instances

deregister() // Optional: deregister the hooks when no longer needed
`

Known Limitations

- Support Node.js since v22.15.0, and doesn't support Deno.
- For Bun, clearRequireCache works, but init is not needed since ESM imports is the same as CJS requires.
- Yarn PnP is not supported on Node.js < v24.
- Only supports ESM modules by default. CommonJS cache can be cleared by clearRequireCache.
- require(esm)` is not supported. Please track this PR.
