async functions not being transpiled correctly with ts-node #1504

seems to be a TypeScript problem |
Hi @ORESoftware, thanks for the question! This is a transpilation issue, as we can only detect native |
@hargasinski this is a problem - yes I see that it gets transpiled to this: #!/usr/bin/env node

See last paragraph: http://caolan.github.io/async/global.html This is a transpiler issue. If the generated function had You'll have to wrap the |
I filed this issue with TypeStrong

there's a video demonstrating the problem
here is the offending code:
who/what is to blame? thanks
