Description

When the Node.js version is v22.2.0 (released on 2024-05-15), the ng build command hangs up. Node.js v22.1.0 doesn't.
Angular CLI is not supporting that version of Node.js officially, but on Firebase App Hosting, the build environment is using Node.js v22.2 today by default. So it is an easy situation for developers to get stumped.

My workaround is to set engines.node field in package.json as "20". App Hosting builder can determine the Node.js version to install.

Minimal Reproduction

• set Node.js version to v22.2.0
• ng new on @angular/cli@latest (v17.3.7)
• ng build
• print Building... and never finished.

Does this repro using Angular 18 RCs?

@JoostK Yes, it reproduces the same situation even after ng update @angular/core @angular/cli --next.

Unfortunately, this is a regression introduced by Node.js, and it's not something we can address on our end. For more details, see: Node.js Issue #53097.

It seems that the "regression" was intentional from Node.js' perspective. Unfortunately, this breaking behaviour happened in a minor version of Node.js, We will need to put in some work to address it on our end as it's not as trivial to solve.
