When working on my project in VueJs JavaScript, I want to be able to see console messages if any of my Promises are not fulfilled and do not have a catch block.
I attempted using the following code:
Promise.reject("error!");
window.addEventListener('unhandledrejection', event => {
console.log('i am error')
});
Unfortunately, this approach did not work. Is there another method I can try? Or how can I resolve this issue?
unhandledrejection is specifically designed for the native Promises found only in Chrome at this time. If you wish to capture and log these errors in other browsers, you will need to replace the native Promise with an alternative implementation such as bluebird:
Promise.reject("error!");
window.addEventListener('unhandledrejection', event => {
console.log('i am error')
});<script src="https://cdnjs.cloudflare.com/ajax/libs/bluebird/3.5.1/bluebird.js"></script>It's important to ensure that bluebird is the first script to be loaded.
