What version of Hugo are you using (hugo version)?

$ hugo version
hugo v0.137.0-59c115813595cba1b1c0e70b867e734992648d1b+extended linux/amd64 BuildDate=2024-11-04T16:04:06Z VendorInfo=gohugoio

Does this issue reproduce with the latest release?

Yes. It was also present in earlier versions, such as 0.128.0.

I'm pretty sure the issue title isn't true in general, so it must something ... special.

• What do you mean by watch? hugo server --watch?
• Do you have a complete and failing example living somewhere?

Yes, hugo server --watch.

• Do you have a complete and failing example living somewhere?

I just created a testing branch with the code snippets mentioned above.

git clone -b custom-output-watch [email protected]:razonyang/hugo-testing.git hugo-13014

cd hugo-13014

hugo server --watch -p 1111

And then I modified the layouts/partials/index.json, http://localhost:1111/search.json won't re-render until restarting Hugo server.

I can reproduce it on both Linux (as shown in the video I posted) and Windows.

+1 This issue is also happening to me - the changes are not reflecting if change a particular file until we restart the server.
Currently using hugo v0.114.0+extended darwin/arm64 BuildDate=unknown

I came on this app to get help in getting my money from Blockchain and I'm not sure what or who to ask so if I cause any problems I'm sorry I just needed help and I need to get support.
