Option to leave comments in templates

[iskathi]

🚀 feature request

Relevant Package

This feature request is for @angular/core

Description

Comments are removed in the rendered angular view. We are using another framework alongside angular whose bindings are within the comments. Our whole code base is written using that framework and we cannot afford to stop development to completely migrate all our code to angular. Which is why we want to do it in small iteration.

Stackblitz sample: https://stackblitz.com/edit/angular-zhw3az?file=src%2Fapp%2Fapp.component.ts

Describe the solution you'd like

An option within the Component decorator to leave comments

@component({
selector: 'my-app',
templateUrl: './app.component.html',
styleUrls: [ './app.component.css' ],
HTMLComments: true
})

Describe alternatives you've considered

The alternative would be to completely rewrite all our views changing those bindings.

Shouldn"t this be a tsconfig option?

Shouldn"t this be a tsconfig option?

Seemed specific to the template engine and felt right having it near templateUrl option, but angularCompilerOptions could also work

Thank you for submitting your feature request! Looks like during the polling process it didn't collect a sufficient number of votes to move to the next stage.

We want to keep Angular rich and ergonomic and at the same time be mindful about its scope and learning journey. If you think your request could live outside Angular's scope, we'd encourage you to collaborate with the community on publishing it as an open source package.

I think that it is possible to make some kind of white list, which comments should not be removed from the templates.

This makes sense. We should review our comments strategy in templates and have 2 types of comments:

• HTML ones that "survive" compilation
• other comments removed by the compiler
