                  function checkOrSetAlreadyCaught

                  checkOrSetAlreadyCaught: (exception: unknown) => boolean;
                  • Checks whether or not we've already captured the given exception (note: not an identical exception - the very object in question), and marks it captured if not.

                    This is useful because it's possible for an error to get captured by more than one mechanism. After we intercept and record an error, we rethrow it (assuming we've intercepted it before it's reached the top-level global handlers), so that we don't interfere with whatever effects the error might have had were the SDK not there. At that point, because the error has been rethrown, it's possible for it to bubble up to some other code we've instrumented. If it's not caught after that, it will bubble all the way up to the global handlers (which of course we also instrument). This function helps us ensure that even if we encounter the same error more than once, we only record it the first time we see it.

                    Note: It will ignore primitives (always return false and not mark them as seen), as properties can't be set on them. {@link: Object.objectify} can be used on exceptions to convert any that are primitives into their equivalent object wrapper forms so that this check will always work. However, because we need to flag the exact object which will get rethrown, and because that rethrowing happens outside of the event processing pipeline, the objectification must be done before the exception captured.

                    Parameter A

                    thrown exception to check or flag as having been seen


                    true if the exception has already been captured, false if not (with the side effect of marking it seen)

                    An object that contains a method to be wrapped.

                    Parameter name

                    The name of the method to be wrapped.

                    Parameter replacementFactory

                    A higher-order function that takes the original version of the given method and returns a wrapped version. Note: The function returned by replacementFactory needs to be a non-arrow function, in order to preserve the correct value of this, and the original method must be called using `origMethod.call(this, <other args>) or origMethod.apply(this, [<other args>]) (rather than being called directly), again to preserve this`.



                  function forEachEnvelopeItem

                  forEachEnvelopeItem: <E extends Envelope>(
                  envelope: Envelope,
                  callback: (
                  envelopeItem: E[1][number],
                  envelopeItemType: E[1][number][0]['type']
                  ) => boolean | void
                  ) => boolean;
                  • Convenience function to loop through the items and item types of an envelope. (This function was mostly created because working with envelope types is painful at the moment)

                    If the callback returns true, the rest of the items will be skipped.

                  function getDomElement

                  getDomElement: <E = any>(selector: string) => E | null;
                  • Gets a DOM element by using document.querySelector.

                    This wrapper will first check for the existance of the function before actually calling it so that we don't have to take care of this check, every time we want to access the DOM.

                    Reason: DOM/querySelector is not available in all environments.

                    We have to cast to any because utils can be consumed by a variety of environments, and we don't want to break TS users. If you know what element will be selected by document.querySelector, specify it as part of the generic call. For example, const element = getDomElement<Element>('selector');

                    Parameter selector

                    the selector string passed on to document.querySelector

                    We always prefer to use local package, thus the value is not returned early from each try/catch block. That is to mimic the behavior of require.resolve exactly.
