UI-Router state visualizer and transition visualizer

UI-Router State Visualizer and Transition Visualizer

Try the Demo plunker

What

Visualizes the state tree and transitions in UI-Router 1.0+.

This script augments your app with two components:

1. State Visualizer: Your UI-Router state tree, showing the active state and its active ancestors (green nodes)

   • Clicking a state will transition to that state.
   • If your app is large, state trees can be collapsed by double-clicking a state.
   • Supports different layouts and zoom.

2. Transition Visualizer: A list of each transition (from one state to another)

   • Color coded Transition status (success/error/ignored/redirected)
   • Hover over a Transition to show which states were entered/exited, or retained during the transition.
   • Click the Transition to see details (parameter values and resolve data)

How

The Visualizer is a UI-Router plugin. Register the plugin with the UIRouter object.

Locate the Plugin

• Using a <script> tag

  Add the script as a tag in your HTML.

  <script src="//unpkg.com/ui-router-visualizer@3"></script>

  The visualizer Plugin can be found (as a global variable) on the window object.

  var Visualizer = window['ui-router-visualizer'].Visualizer;

• Using require or import (SystemJS, Webpack, etc)

  Add the npm package to your project

  npm install --save ui-router-visualizer
  

  • Use require or ES6 import:

  var Visualizer = require('ui-router-visualizer').Visualizer;

  import { Visualizer } from 'ui-router-visualizer';

Register the plugin

First get a reference to the UIRouter object instance. This differs by framework (AngularJS, Angular, React, etc. See below for details).

After getting a reference to the UIRouter object, register the Visualizer plugin

var pluginInstance = uiRouterInstance.plugin(Visualizer);

Getting a reference to the UIRouter object

Angular 1

Inject the $uiRouter router instance in a run block.

// inject the router instance into a `run` block by name
app.run(function($uiRouter) {
 var pluginInstance = $uiRouter.plugin(Visualizer);
});

Angular 2

Use a config function in your root module's UIRouterModule.forRoot(). The router instance is passed to the config function.

import { Visualizer } from "ui-router-visualizer";

...

export function configRouter(router: UIRouter) {  
  var pluginInstance = router.plugin(Visualizer);
}

...

@NgModule({
  imports: [ UIRouterModule.forRoot({ config: configRouter }) ]
  ...

React (Imperative)

Create the UI-Router instance manually by calling new UIRouterReact();

var Visualizer = require('ui-router-visualizer').Visualizer;
var router = new UIRouterReact();
var pluginInstance = router.plugin(Visualizer);

React (Declarative)

Add the plugin to your UIRouter component

var Visualizer = require('ui-router-visualizer').Visualizer;

...
render() {
  return <UIRouter plugins=[Visualizer]></UIRouter>
}
