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({
  // 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

• Supports Node.js v22.18.0 and later; Deno is not supported.
• Yarn PnP is not supported on Node.js versions earlier than v24.
• In Bun, clearRequireCache works, but init is unnecessary because ESM imports behave the same as CommonJS requires.
• Only ESM modules are supported by default. The CommonJS cache can be cleared with clearRequireCache.
• require(esm) is supported starting in Node.js v24.13.1.
