Not able to kill the process during build

[groenroos]

Operating system

macOS Sonoma 14.4.1

Eleventy

3.0.0

Describe the bug

While Eleventy is building the site, it's not possible to kill the process with Ctrl-C. Only after the build is complete, will the Ctrl-C take effect and Eleventy exits with code 1.

With a large site where build times are in the tens of seconds, this can get frustrating, especially when you already know the build will fail (e.g. because of missing npm dependencies when switching git branches).

Reproduction steps

1. Start a build of a large site
2. Wait until the templates start processing (i.e. after any async data has been fetched)
3. Try to kill the process with Ctrl-C
4. The process will not die until after the build is complete

Expected behavior

The build should be interrupted and the process should exit instantly.

This is indeed a new behavior I've noticed with Eleventy 3.

Ctrl + C doesn't kill the shell execution, I have to use ps to get the process id then kill it.

There are similar issues open in npm's repository.

For example:
