Repro steps.

ng build --prod

The log given by the failure.

ng: gaio-front/src/app/views/studio/canvas/canvas-tree/canvas-tree.component.html (349,6): Property 'showRemoveProcessModal' does not exist on type 'CanvasTreeComponent'.

Desired functionality.

When build the app, this erros is printed on terminal/console. It would be helpfully if this errors appears on dev mode too.

1. Why this errors does not show on ng serve, but shows on ng build --prod?
2. How make this erros show on development mode too(ng serve)?

@calebeaires Is there a repo I can take a look at?

[calebeaires]

@sumitarora, thanks for your help!

My team is working on a private repo right now, even if it is an open source project. But, about this issue, I release that this is related to variables that have been declared on template (html) but not on component (private/public properties)

Maybe it is related to this issue: Error with build --prod & templates since angular/cli 1.0.

So, how to make angular-cli show thoses errors via a development server mode, not only on build --prod time.

@calebeaires I see this has been merged in master but yet to be release. You can try using the master branch and see if error still exists or not.

You can enable AOT (--aot) for development which should generate any errors related to the compilation of the templates. Please note this will significantly increase rebuild times.

[filipesilva]

@calebeaires such errors only happen during AOT compilation, which is used for production builds. I agree it's a nasty surprise to find new errors when doing prod builds, but the alternative would be to use AOT all the time and as @clydin said this would massively increase rebuild times.

[NeelBhatt]

Is there any way I can suppress those errors occurred only with AOT compilation? For example, there is an error comes with --prod but if I try to fix that error, it breaks my functionality, is there a way to suppress specific error and allow the build to pass in --prod?
