🐞 bug report

Description

I'm trying to build & run my Angular SSR (Angular Universal) app, whereas the 3rd script fails:

ng run web:build --configuration=production
ng run web:server --configuration=production
ng run web-ssr:serve

With the below error.

🔥 Exception or Error

Anything else relevant?
My server bundle target is es2015.

I've tried the solution proposed in #35327 but it didn't resolve the issue.

Could you share a minimal reproduction, @matthiasunt? This sounds like a configuration issue, but it is hard to know for sure without looking at a concrete reproduction.

_{Moving the issue to the CLI repo, because people there are more likely to be able to help with this issue.}

Hi any progress on this issue.

Hi @muzammalrahim,

The problem is that some parts of domino are require JS to be in sloppy mode but ES2015 modules are always strict.

There are 2 possible workaround for this:

1. change the module target to commonjs
   Set the module to commonjs in your tsconfig.server.json, this however has the drawback of disabling lazy-loading on the server.

2. set domino as an external dependency.
   In angular.json under server.options add "externalDependencies": ['domino'], this will cause domino not to be included in your server bundle, and it will be required during runtime.

@alan-agius4 thanks so much! Went with option 2 and I'm not getting the error anymore.
