CallGraphTo for JavaScript

Displays calls made to a specified function, showing the call graph inbound to the target function.

Overview

This query identifies all call sites that invoke a named function, producing an inbound call graph. Given a target function name, it reports each caller and call location, which is useful for understanding how a function is used across the codebase.

The query accepts function names via an external predicate (targetFunction).

Use Cases

This query is primarily used for:

  • Finding all callers of a specific function
  • Impact analysis before modifying a function signature
  • Understanding usage patterns and entry points

Example

The following JavaScript code demonstrates inbound calls to targetFunc:

function targetFunc() {} // Target function for analysis

function caller1() {
  targetFunc();
}
function caller2() {
  targetFunc();
}

Running with targetFunction = "targetFunc" produces results showing each call site with the message pattern Call to `targetFunc` from `caller1.

Output Format

The query is a @kind problem query producing rows of:

  • select call, "Call to `target` from `caller`"
