Returns current stack as call sites

NPM

Build status semantic-release js-standard-style

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.
