import-without-cache

Import ES modules without cache.

Features

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

Install

npm i import-without-cache

Usage

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()

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.
• Only supports ESM modules by default. CommonJS cache can be cleared by clearRequireCache.
• require(esm) is not supported.
