Node.js v22.18.0 (LTS) has been released and introduced type stripping by default, allowing it to execute TypeScript files without additional configuration. This feature is experimental and subject to change. To disable it, pass the "no-experimental-strip-types" CLI flag. Other notable changes include updating amaro to 1.1.0, adding watch-mode-related flags to node.1, adding islandryu to collaborators, implementing import.meta.main, allowing correct handling of bursts in fs-events with AsyncIterator, propagating permission model flags on spawn, adding support for the readBigInts option in db connection level, and making worker async disposable. Commits include fixing dead code, removing dead code, and fixing the SHAKE128/256 breaking change introduced with OpenSSL 3.4. Node.js GitHub Bot also updates amaro to 1.1.0, 0.5.3, 0.5.2, and 0.5.0. The changes aim to improve the user experience and maintain the stability of Node.js.

Node.js v22.18.0 (LTS)

Notable Changes

Type stripping is enabled by default

Node.js will be able to execute TypeScript files without additional configuration:

$ echo 'const foo: string = "World"; console.log(`Hello ${foo}!`);' > file.ts$ node file.tsHello World!

Shell SessionCopy to clipboard

There are some limitations in the supported syntax documented at  https://nodejs.org/api/typescript.html#type-stripping.

This feature is experimental and is subject to change. Disable it by passing --no-experimental-strip-types CLI flag.
