Allow bigint literals in templates #44852
Description
Which @angular/* package(s) are relevant/releated to the feature request?
compiler
Description
Currently, templates does not seems to support bigint literals.
Because of that, the following code does not compiles:
<!-- Argument of type 'number' is not assignable to parameter of type 'bigint'. -->
<button (click)="onClick(55n)"></button>onClick(v: bigint) {
console.log("clicked %o", v);
}The only way to get this to work it to either
- re-export the
BigIntfunction from the component code - use a variable defined in the component code
<button (click)="onClick(BigInt(55))"></button>
<button (click)="onClick(aBigInt)"></button>BigInt = BigInt;
aBigInt = 55n:
onClick(v: bigint) {
console.log("clicked %o", v);
}Proposed solution
Allow bigint literals (ending with n) in the templates and treat them as bigint not number.

I would like to give it a try, it is on compiler parser ? ?

@Grubba27 we haven't made a decision if we want to support this in Angular templates, so I'd hold off from creating a PR for now.

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've added this one to the overarching issue of #43485 where we are tracking all of the potential improvements to the template syntax. I'll close this issue, and we'll track progress on the other issue.
