How to debug angular app using angular-cli webpack

问题:

I used angular-cli@1.0.0-beta.10 before and now I updated to angular-cli@webpack beta.11. After a lot of custom changes I got it to work.

The only thing is that now I can not debug my angular app using webstorm and chrome debugger because I don't get any ts files using ng serve. With angular-cli@1.0.0-beta.10 it was very easy to debug my app using the Jetbrains Plugin.

How can I debug my angular app with Webstorm and the Chrome Debugger using ng serve?

How to debug with angular/cli

The new angular/cli version uses webpack which does not compile the ts files to an local directory like dist before (till beta 1.0.0-beta.10). Now it uses some memory like approach.

But you can find the ts Files in the Chrome Developer Tools in the "Sources" tab.

(new) Solution for angular/cli@1.0.0-beta.26 and newer

Notice: This solution was tested with version 1.0.0-beta.26 and 1.2.1

Notice: In this example I used port 5321 instead of 4200. Just use your port.

Debugging with Chrome Developer Tools

While running ng serve (also used in npm start), you can find your sources in the Chrome Developer Tools section: "webpack://":

Debugging Angular 2 App with angular/cli using JetBrains IDE

Just edit your Run/Debug Configuration in Webstorm/PHPStorm to following:

1. Set your Remote URL Path of your project directory to webpack://.
2. Set your Remote URL Path of your src directory to webpack://./src

Debugging with Chrome Developer Tools

While running ng serve (also used in npm start), you can find your sources in the Chrome Developer Tools section: "webpack://":

Debugging Angular 2 App with angular-cli@webpack using JetBrains IDE

Just edit your Run/Debug Configuration in Webstorm/PHPStorm to following: Set your Remote URL Path of your project directory to

webpack:////Users/...FULL_PATH.. //on Mac OSX

or

webpack:///C:/...FULL_PATH.. //example on Windows

Notice: on Windows you only need 3 slashes, on Mac you need 4 slashes after "webpack:"

You can also check your Path by going to http://localhost:4200/main.map and search for any ".ts" File. You can easily copy the path of this file and paste it to your IDE Configuration Dialog.

EDIT: Perhaps you need to map the path adding "/src" to your src folder too. Thanks @born2net

Have Fun.

ok got it working, you need to map both root and src. see here:

hopefully it helps someone,

let me add that sometimes the debugger will miss your breakpoint so add alert('foo') or ;debugger code just before your breakpoint.

If you are having problems with this, go to your Scripts tab in your debugger and try and align your URL mappings according to what you see.

None of the other answers helped me because my version of angular-cli mapped things a different way.

You can use Augury which is a dev tool extension for the web browsers in order to debug angular applications.

Here is the link you could install:

https://augury.angular.io/

This tool is very useful in viewing the hierarchy of your routing in your application, Module and Components hierarchy and the Dependency Injection overview on each component.

Here is an Inject Graph of my project which illustrate my above explanation:

What finally helped me was to add an additional / (forward slash) after webpack:///, so that there are 4 instead of 3. By default there were 3 forward slashes

The remote URL points to the same parent directory as on the left except the webpack://// schema.

Also you don't need to enable the TS compiler as often suggested.

• MacOS
• Angular-CLI 2.4.1
• WebStorm 2016.3

Please note that the above solutions do NOT let you set breakpoints in the html files of angular components when using IntelliJ. You can only do this in Chrome. I don't understand why this is not possible in IntelliJ.
