Research direction

The failing step is the build stage of cf deploy, which logs "Delegating to npx ng build --prod"; start by finding where the Angular build command is chosen in the deploy path and check how cf migrate detects Angular projects. Reproduce with an Angular 22 project that has a Worker entrypoint and static assets, then run cf deploy --dry-run. Done when the build runs ng build --configuration production and the deploy output still works for Workers.

Description

Summary of the issue

I'd like to use cf with Angular 22, but the Angular build command still uses ng build --prod. Angular CLI 22 no longer accepts that flag.

I migrated an existing Angular app with a Worker and static assets using cf migrate. Running cf deploy --dry-run afterward fails with Error: Unknown argument: prod.

My existing build script uses ng build --configuration production, but cf deploy selects its own command.

Expected behaviour

Support current Angular CLI versions, using ng build --configuration production and handling the resulting output for Workers deployment.

Version of cf used

1.0.0-beta.17

System information and package versions
  • macOS: 26.6.2 (arm64)
  • Node.js: 22.23.2

Reproduction (optional)

In an existing Angular 22 project with a Worker entrypoint and static assets configured in wrangler.jsonc:

  1. Run cf migrate wrangler.jsonc --no-install.
  2. Run npm install -D --save-exact [email protected] [email protected].
  3. Remove the generated dependency-installation TODO and migration guard after installing the dependencies.
  4. Run cf deploy --dry-run.
