We're experimenting with using --harmony_async_await in Node 7, and pared to transpiling with babel for async/await are missing the ability to have long stack traces (.longstacktraces.html).

Obviously, it would be great if there was an option to 'just see this' - on the chrome(ium) side they appear to support it in the inspector, though the latest work on this is after v8.5.4 (i.e. not in Node 7):

An alternative approach would be to get v8 to use bluebird's promise implementation - but how could I do that? Overriding global. Promise doesn't change how async/await behave (they still use the default promises).

  • Interestingly, Emanuel Jöbstl suggests that replacing the built-in promise implementation which you mention actually works! medium./front-end-weekly/…. – kresho Commented Feb 1, 2019 at 14:50

  • 1 @kresho thanks for letting me (and everyone else) know! Perhaps something changed since I'd messed with it, or I just made a mistake. Node/v8 have certainly e a long way since this question was asked. – james.haggerty Commented May 19, 2019 at 9:43

Reset to default 1

Since NodeJS v12 async stack traces are enabled by default.
