Augury

Augury is a Google Chrome Dev Tools extension for debugging Angular 2 applications. You can install the extension from Chrome Store.

Once the extenion is installed you can test it against the demo application https://augury.angular.io/demo/

Supported Version

Currently works with applications built in Angular 2.0.0 using the Angular Component Router version 3.0.0-beta.2.

To view the router graph inject the Router in the application root component as shown below (it must be named router exactly).

export default class KitchenSink {
  constructor(private router: Router) {
  }
}

Example

Support for AoT (Ahead-Of-Time) Compilation

In order for Angular to expose the debug information for AoT applications, you will have to explicitly set the debug flag to true in your project's tsconfig.json as such:

"angularCompilerOptions": {
  /* ... */
  "debug": true
}

Note that this debug flag and development mode in Angular runtime are two completely different settings.

To learn more about AoT compilation, visit this section of Angular documentation.

Support for `enableDebugTools()`

Prior to Angular 2.2.0, enableDebugTools() would clobber ng.probe, which breaks Augury. Prior to that version, this workaround will circumvent the issue.

Development Environment

To develop this extension, the following environment is used:

Node 4.2.3
NPM 3.5.3
TypeScript 1.8.9
typings 1.3.2

Available NPM Scripts

build Build the extension
webpack Run webpack
clean Clean node_modules and typings,
postinstall install typings
start Clean build and run webpack in watch mode

Issues

Known Issues

We are using GitHub Issues for our public bugs. We will keep track on this and will to make it clear when we have an internal fix in progress. Before filing a new task, try to make sure your problem doesn't already exist.

Reporting Issues

The best way to get a bug fixed is to provide a test case with either one of the example apps bundled in the repo, or by making your own Angular 2.0 application illustrating the reduced use case.
