stack-sites

Returns current stack as call sites

Install

npm install -S stack-sites

const stackSites = require('stack-sites')
function foo () {
  const sites = stackSites()
  // sites[0] - stackSites itself
  // sites[1] - this file
  // sites[2] - caller to this function
  const caller = sites[2]
  console.log('I got called from %s in %s line %d column %d',
    caller.functionName,
    caller.filename,
    caller.line, caller.column
  )
}
module.exports = foo

Why?

V8 stack API does not return accurate source locations if the source file
has been transpiled on load, see
Accurate call sites
blog post. Exception stack on the other hand can take source maps into
the account, producing correct line and column information.

Debug

To see the original and parsed stack, run with DEBUG=stack-sites environment variable.
