如何在Large SPA中处理和记录Javascript中的错误

Question

I am new to Javascript , I was wonder like we log error in Server Side programming language in a error.log file . for example in PHP there we can set a error file to log the errors .

Is there a way to do this in Large SPA in Javascript or we just log in console using

console.log()

I have this simple app which loads some json data from API and I have just used the normal alert and console.log methods to show error I would like to know whats the best way to do this.

I understand that I can write a Web Service which can be called every time an error being thrown and using the

window.error or element.error function probably I can send error report to the server where I will write on a log file.

But is Doing rest call on every error thrown is a good way?

Thanks

Browsers won't allow you to write on a file in client so You have to use ajax and write a log on server. Sending errors to server using ajax is a good solution. Also throwing error with alert is not appreciated by any user.
