Support for node's --unhandled-rejections=strict

[alextes]

Desired Behavior

When an unhandled promise rejection occurs I'd like the process to exit. Node even explains in a warning that this is their intended future behavior, if you want that behavior now, you can pass the --unhandled-rejections=strict flag. ts-node does not appear to support it. Or maybe I misunderstand how to pass it, in which case this issue can be read as a suggestion to change the docs.

Alternatives you've considered

Compiling with tsc and running with node. Sadly stack-traces get worse and it's a bit cumbersome in development when running with docker-compose for example.

To answer other Googlers more directly this seems to do it:

node --unhandled-rejections=strict -r ts-node/register main.ts

test main.ts program:

(async () => { throw 'asdf' })()

This is also mentioned in the docs: https://typestrong.org/ts-node/docs/configuration#node-flags
And there is a discussion thread which goes into even more detail: #1182

Per the docs, an alternative syntax for the lazy:

NODE_OPTIONS='--unhandled-rejections=strict' ts-node main.ts
