You mean something like:

process.on("unhandledRejection", function(p, reason){
  console.log('Uncaught error: ', reason); // this will get called
});

Promise.resolve().then(x => { throw "Hah"; });

Post Mortem Debugging in NodeJS in the Light of Promises

Context:

we're discussing how we can safely abort on unhandled rejections and obtain meaningful debugging information. Related reading: https://gist.github.com/misterdjules/2969aa1b5e6440a7e401#file-post-mortem-debugging-with-promises-md.

In particular, we're discussing https://gist.github.com/misterdjules/2969aa1b5e6440a7e401#removing-implicit-trycatch-blocks-from-v8s-promises-implementation

Othe recommended reading: On unhandledRejection https://gist.github.com/benjamingr/0237932cee84712951a2
