调研方向

Start by reading MemberHostBindings::of in directive/metadata.rs and compare its stored member name with ngtsc's getSafePropertyAccessString behavior described in the issue. Trace how that metadata becomes partial and full output, including the non-identifier example. Done means both output forms access my-prop as a property and identifier members such as m still work.

描述

Found while reviewing #682.

ngtsc's extractHostBindings stores a @HostBinding member as getSafePropertyAccessString("this", member.name) (compiler-cli chunk-G5LDCSK3.js:3435): "this.m", or this["my-prop"] for a name that is not an identifier. Oxc's MemberHostBindings::of (directive/metadata.rs:201) stores the bare member name ("m", "my-prop").

@Directive({ selector: '[d]' })
export class D {
  @HostBinding('id') 'my-prop' = 1;
  @HostBinding('title') m = 2;
}
result
ngtsc partial properties: { "id": "this[\"my-prop\"]", "title": "this.m" }
Oxc partial properties:{id:"my-prop",title:"m"}
Oxc full ɵɵdomProperty("id", (ctx.my - ctx.prop))("title", ctx.m) — wrong: parsed as a subtraction

For identifier names only the partial text differs (both link to ctx.m). For names that are not identifiers, both full and partial output read the wrong value. ngtsc emits ctx["my-prop"].
