In Node.js I have a module which consists of just one function. The function returns promise and the promise could be rejected. Still I don\'t want to force all users of the

In general, using a custom library like bluebird you can suppress rejections just from your code but nowhere else. Native promises can't do this yet.

You can however manually suppress a promise by adding a catch handler for it.

 function yourExportedFunction() {
     const p = promiseThatMightRejectFn(); 
     p.catch(() => {}); // add an empty catch handler
     return p;
 }

This way you are explicitly ignoring the rejection from the promise so it is no longer an unhandled rejection just a suppressed one.
