How to Timeout After Calling Await on an async function in Javascript/Node

Question

I have an async function web3.eth.net.isListening() that causes the following statement to be stuck forever if there is an error:

await web3.eth.net.isListening()

Question: How can we let the above await statement timeout after 10 seconds, and do a console.log to show that an error has occured?

Answer 1

You can use Promise.race() to provide a second Promise that is tied to a timeout.

await Promise.race([
    web3.eth.net.isListening(),
    new Promise(function(resolve) {
        setTimeout(function() {
            console.log('Timed out');
            resolve();
        }, 10000);
    }),
]);
