的NodeJS。 我可以在一个地方处理错误吗？ 没有尝试抓住块

Question

Node said that I should catch errors on all my promises.

Does exist a good practice for handling the same errors in one function? I don't want to write always the same catch block for all requests.

My code looks like:

(async () => {
  try {
    await makeRequest()    
  }
  catch(e) {
    console.error(e)
  }
})()

Answer 1

Try this :

makeRequest()
    .catch(err => {
        // console.error(err)
    })

Answer 2

For async IIFE (IIAFE) error handling is performed as:

(async () => {
  await makeRequest()    
})().catch(console.error);

Notice that in Node.js console methods are bound to proper context, so they can be passed as callbacks.
