Module Jsoo_runtime.ErrorSource

Sourcetype t
Sourceval raise_ : Jsoo_runtime.Error.t -> 'a
Sourceval attach_js_backtrace : exn -> force:bool -> exn

Attach a JavaScript error to an OCaml exception. if force = false and a JavaScript error is already attached, it will do nothing. This function is useful to store and retrieve information about JavaScript stack traces.

Attaching JavaScript errors will happen automatically when compiling with --enable with-js-error.

Sourceval of_exn : exn -> Jsoo_runtime.Error.t option

Extract a JavaScript error attached to an OCaml exception, if any. This is useful to inspect an eventual stack trace, especially when sourcemap is enabled.

The Error exception wrap javascript exceptions when caught by OCaml code. In case the javascript exception is not an instance of javascript Error, it will be serialized and wrapped into a Failure exception.
