UI-Router State Visualizer and Transition Visualizer

Try the Demo plunker

Image of Visualizer


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)


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="//"></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$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);
  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>
