Is there a way to stop mangling names for a class/interface?

[Svyatoslav Kuzmich [JB]]

Yes! It can be done using JsName or experimental JsExport

[turansky]

Is it possible to disable mangling without exporting?

[Svyatoslav Kuzmich [JB]]

JsName does that

[turansky]

What about whole class/interface (without name duplication)?

[Svyatoslav Kuzmich [JB]]

What are your use-cases for “JsExport but without export”?

[Svyatoslav Kuzmich [JB]]

Is it for calling external API that expects certain names?

[turansky]

0. “missed” members in declarations
Last example - HTMLElement has more abstract members

1. Like entities
For example if you have x, y, width, height
you become rect like and can be converted to Rect class

2. Templates

Is it for calling external API that expects certain names?

Yes, for example it can be used in templates like this

[Svyatoslav Kuzmich [JB]]

Thanks! I’m thinking that we would also need let IR DCE know that these would be used externally so it would keep them alive.

One more example - template converters
