Similar packages

Other packages similar to caller-callsite

callsites

The 'callsites' package provides functionality similar to caller-callsite by returning an array of call sites (stack frames), allowing developers to inspect the call stack. It differs in that it gives a broader view of the call stack rather than focusing on the immediate caller.

stack-trace

The 'stack-trace' package is another alternative that allows capturing stack traces. While it provides detailed information about the call stack, similar to 'callsites', it also includes features for parsing and working with stack traces, offering a more comprehensive approach compared to caller-callsite.
