callsites

Access call site data from the V8 stack trace API

• Features the new zero-cost AsyncStackTrace API
• Determine otherwise inaccessible downstream data, like import.meta.url
  • (this is the strategy used by the deno_blog project)

import { callsites } from "https://deno.land/x/callsites/mod.ts";

const call = () => callsites()[0];
const site = call();

site.getFileName();
// => "file:///Users/foo/bar.ts"
site.isAsync();
// => false
