Description

Command

build

Is this a regression?

  • Yes, this behavior used to work in the previous version

The previous version in which this bug was not present was

Issue with requested main.js filename not including the hash when deployed to firebase app hosting

Description

I've got an angular/ssr 20.1.1 site where all but one test route is csr (the ssr route is not used in this bug repro). I seem to be having some issues with filename hashing when deploying to firebase app hosting

  1. ng build --configuration=production
  2. npm run serve:ssr (to test)
  3. firebase deploy --only apphosting:mybackend2

when i do step 2 and visit my local site csr page i see main-UKL5WJPJ.js being downloaded successfully
And I see this file in the filesystem: dist\diveplan\browser\main-UKL5WJPJ.js.

When I deploy to firebase app hosting and view my site, I see the network trace refer to main.js without a hash in the filename! This is causing the site to fail to render. There is no dist\diveplan\browser\main.js

Minimal Reproduction

This is for a production site with many iterations that started from angular 12.
I can try to build a min repro if needed. Should this be working? Any pointers to area of further diagnostics would be appreciated!
Thank you!
