问题
In Webstorm, I am running gulp serve task that launches localhost:9000 stub angular project generated with yo. I am trying to debug JavaScript code and this is what i have tried:
- I run gulp as a debug task, I can only debug gulp file lines
- I try to run gulp serve before JavaScript, it starts serving and Webstorm never gets to launching its JavaScript debug session
- I try to run JavaScript debug, I don't get breakpoints inside my code.
What is the workflow in this situation?
PS. i am not trying to debug code inside chrome developer tools, i want my breakpoints to work in Webstorm
回答1:
In your Javascript - put debugger; between two of your lines, and pop open your Developer Tools in Chrome. When you refresh the page - if your script runs, it should stop where you put the debugger; and you'll be able to hover on different variables to see their values. Very powerful and basic tool.
Also, if you don't want to have the script stop - you can console.log(variable); to have the Developer Tools console print out the variable.
Example:
var somethingOrOther = function(){
var blah = 'foo';
console.log(blah);// to print to console
debugger; // to stop script at this point and look around
};
Don't forget to remove the debugger; when you're done.
I recommend using jshint in your gulp to make sure you don't miss those kinds of things.
