How to warn when you forget to `await` an async function in Javascript?

I'm using Babel and Webpack. If I forget to await an async function, it can often go unnoticed. Once in a while, if I forgot the await, an error occurs in the async function and I get an Unhandled promise rejection. Then, I realize that I forgot the await.

Is there a way to get a warning when I forget to add an await?

  • I think OP is looking for something like no-floating-promises from tslint see: https://palantir.github.io/tslint/rules/no-floating-promises/
