Angular2 router VS ui-router-ng2 VS ngrx router

NGRX Routerdocs

ngrx router is Deprecated! There is migration strategy from ngrx router to the standard Angular2 Router.

Angular2 Routerdocs

  1. Default solution from Angular team
  2. Was inspired by UI-router from AngularJS
  3. Built for components

Angular2 Router has almost all UI-router features.

NG2 UI-routerdocs

Well known UI-router from AngularJS updated for the Angular2. From the known advantages - makes smoother update from AngularJS UI-router to ng2 UI-router.

Let's compare syntax of UI-router both versions with Angular2 Router.

AngularJS UI-router :

Angular2 UI-router :

Angular2 Router :

(Update: property - was removed after V3-alpha7. Because it didn't work out with lazy loading of routes.)

As we can see, in general, Angular2 Router is pretty much the same. As addition need to say that it support most of the common features like static/dynamic data sharing through the routes, nested views etc.

  • Same location strategies (Path and Hash)
  • Similar route definitions
  • Similar services:
    • $state.go and Router.navigate
    • $stateParams and RouteParams
    • $state.current.data and RouteData
  • Similar directives
    • ui-view and router-outlet
    • ui-sref and routerLink

Angular2 Router had taken best of UI-router experience and implemented it. If you need easy migrate your code base with AngularJS UI-router to Angular2 fast and smoothly, you can try Ng2 UI-router, otherwise, I think Angular2 Router will fit best. Even if you decided to use NG2 UI-router, check all pros and cons, at current point I feel like the community is going to choose a standard solution from the Angular team which means better support.

Easier AngularJS Routing with Angular UI Router

Although AngularJS ships with built-in routing, you may sometimes find it limiting; the Angular UI Router framework can help ease the pain. The native AngularJS routing implementation is responsible for initializing controllers that match application routes. Although this functionality works well in basic scenarios, in advanced situations, you quickly find that Angular's native routing:

  • Requires you to manually change URLs strings throughout your code base when a URL changes.
  • Requires you to remember the route syntax verbatim to navigate to a page.
  • Does not offer nested views.
  • Does not offer named views.
  • Does not allow you to pass around data during navigation.

As an alternative, the Angular UI Router framework is an abstraction layer for routing that features a more declarative approach to navigation. The UI Router framework also fills in some of the gaps of the native implementation by providing nested and named views, allows you to pass data between views, and much more.

The Angular UI Router framework is an abstraction layer for routing that features a declarative approach to navigation

In this article, you'll learn to build a simple application that uses the UI Router framework. Along the way, you'll become familiar with states, how to resolve dependencies, and you'll learn various methods for navigation.

Understanding States

Perhaps the best way to appreciate the problem that the UI Router framework hopes to solve is to consider the nature of the Web. In most applications when you create a link to a page, you define an explicit URL path. For instance, if you wanted to navigate to your site's Products page, you may have a URL like:

There are two problems with this situation. The first is that you must remember the exact literal path to the Products page each time you establish a link. Although the example given here may be easy to recall, many real-world URLs are not so easily memorized. You encounter the next problem when the inevitable happens and someone decides to change the path to something else. When a URL changes then you have to make sure all existing links are updated to point to the new location.

Instead of having to keep track of the URL paths verbatim, wouldn't you rather just tell the application to “go to the Products page”? By allowing the application to concern itself with navigation, you're relived of having to know the literal path and are shielded from broken links caused by the inevitability of change. Using states gives you this level of flexibility. A state encapsulates a URL location, the state name, specialized data for the view, identifies a way to locate or generate the view, and can even expose custom events.

Introducing Angular UI Router

Angular UI Router is a framework that wholly replaces the native routing available in AngularJS. The UI Router is very similar to the native AngularJS routing in that applications are composed of a shell that holds a placeholder for dynamic content. Figure 1 demonstrates how the application shell hosts an element that uses the directive. As state rules are evaluated in the framework, HTML content is rendered inside the placeholder.

Figure 1:      The UI Router framework adds HTML content into a placeholder on the page.

Angular UI Router is a framework that wholly replaces the native routing available in AngularJS.

Beyond rendering HTML content, the UI Router framework supports URL routing, the ability to resolve dependencies before controllers are initialized, named and nested views, utility filters, state change events, and declarative transitions among states.

Navigating Among States

There are a few different ways you can use to move between different states. The first way is the directive. You're probably familiar with the attribute of the HTML anchor tag (which represents a ypertext erence); similarly, the directive refers to a tate erence. You use the directive by declaring a state name with the directive applied to an anchor. For example:

As the UI Router framework evaluates this directive, the anchor is transformed to have the appropriate URL value. For example:

Notice that the element is updated to include an attribute with a value corresponding to how the URL must be updated to navigate to the About Us page. The directive is quite flexible. It supports simple scenarios as well as ways to deal with nested states and even parameterized values.

The next approach for navigating among states is to use a method off of the object that's available to an Angular controller. In this next snippet, you can see how the method is implemented to call and transition the application to the state.

The object is injected by the UI Router framework and includes a number of methods to help you manage and manipulate state in the application. The value here is that you tell the application to “go” to the state and you're freed from knowing the literal URL path to the page.

Downloading and Installation

There are a number of different ways you can get access to the UI Router framework. You can download the latest version directly from the GitHub repository at https://github.com/angular-ui/ui-router. Alternatively, you can install the framework via Bower or NuGet or even include CDN links in your pages; both are available at http://cdnjs.com/libraries/angular-ui-router.

Using Angular UI Router

What follows is a tutorial demonstrating how to build a simple static content-based application using the UI Router framework. Figure 2 depicts the home page sample application you learn to build as you read through this article. From this screenshot, you can see the application shell and how the contents of the home page are injected into the placeholder using the directive.

Figure 2      : The homepage and default state of the application

You can change states to navigate to the contact page, as shown in Figure 3. The mechanism on the contact page uses the object's method by passing a state name to the method.

Figure 3      : The contact page

The next state is associated with the article's list page, as seen in Figure 4. Here, an array of article data is made available to the view after having the raw values injected into the controller by the UI Framework. Navigation on this page is facilitated through the directive that allows you to declaratively express the application state to which you want to navigate.

Figure 4      : The articles list page

The final page, illustrated in Figure 5, shows how a nested state is used in the application.

Figure 5      : The article detail page

Configuration

In order to start working with the UI Router framework, you have to configure the page. The first step is to add the application name into the attribute of the HTML element on the page. Here, the app name is simply .

Next, you need to add the directive to an element on the page to act as the placeholder for content injected by the framework. In this instance, the directive is added to a element.

Finally, you must reference both Angular and Angular UI Router on the page.

This code snippet also includes reference to the script in the folder that holds the code to initialize the Angular application. The initialization process is where most of the setup and interface with the UI Router framework is implemented.

Defining States

As stated previously, the basis for the UI Router framework is the use of different states in an application. By accessing each of these states, the application can navigate to or reconstitute itself to circumstances within the lifecycle of the application. The following section demonstrates how to define the states for the application; all of the code is implemented in the file. Each section is examined in isolation, but if you'd like to see the full initialization script, please refer to Listing 1.

Listing 1: Application Initialization

The first step is to configure UI Router in your AngularJS application. After naming the module, you have an opportunity to register the UI Router framework as a dependency of the application by adding the literal into the dependencies array. (Note how the comment denotes a placeholder for code in a subsequent snippet.)

Once the module is defined and dependencies are registered, the application is set up to run an anonymous function that executes during the configuration phase of the application. Here, there are a few resources injected into the function that are relevant to the UI Router framework.

The object features the method that allows you to define granular application states that may or may not coincide with changes to the URL. The is an object that gives you control over how the browser's location is managed and observed. In the context of the UI Router, is used to help define a catch-all navigation scenario. Each of these objects are discussed in more detail in coming code snippets. (Again, note that subsequent code snippets are placed at the position of the placeholder comment in the previous snippet.)

Each application state is defined by providing a name and telling the framework where to find the markup for the view. Here, the home state is defined by providing the root location for the and a value for the property.

This tells the application to load the contents of the file into the placeholder when the user navigates to the root of the application. Here, you begin to see one of the advantages of having state-centric routing. If, for some reason, you wanted the URL for the home state to point to instead of the bare root location , that change would only need to happen here in the configuration. This state forgoes any advanced setup and loads a static page into the browser. There may be other times when you want to associate a specific controller with the state.

The contact state is set up to load the markup of the page into the placeholder. Beyond doing a basic replace operation, the is also associated to the view scoped at the level of the DOM element that hosts the directive.

As shown in Figure 3, the Contact page includes a button to navigate to the Articles page. The navigation is done in the and demonstrates how to wire-up a controller to a view loaded in on demand by the UI Router framework.

The Article page's state takes the configuration a step further by adding values into the object that resolves any configured values defined in the object. The purpose of this state is to render a list of the available articles on the site. This state is set up to have the article information available to the controller before it's instantiated. In the following snippet, the state defines a value in the object.

In this case, the property points to the string . When you pass a string as a value to the property, the framework contacts a service registered under the same name and resolves the service down to its final value. In this case, the returns a promise so the associated controller isn't instantiated until the service's promise is resolved and the final object is available as an injectable value for the controller. The implementation for the is available in Listing 3.

Listing 3: Articles Service

After the list of articles is rendered to the user as depicted in Figure 4, the user may select an article and drill into the site's content. This action is represented by a nested state. Notice how the state name includes a dot between and to denote a parent and child relationship among the states.

Here, there's a special rule applied to how the property is evaluated. Since this is a nested view (as indicated by the dot in the state name) the value of the property will be concatenated with the parent state's value. This means that any matching states will have a URL that begins with and then includes the page name of the article.

The presence of the colon is indicative of a URL parameter. By introducing a parameter into the URL, the state definition becomes flexible enough to handle any state that matches the relationship it has with its parent state. This state also features a function that is run to return the value for . Using a function here gives you an opportunity to use the parameters defined in the of the state. Whatever name you give the parameter in the property matches the property name of the object. Therefore, this state takes the passed in the URL to use in the function to access individual content files that are eventually injected into the element hosting the directive.

This is the last state defined in the application. To see how all the states are implemented in the actual initialization script, refer to Listing 1.

The final command required to give the application is what to do if the user tries to access a URL that isn't defined in the method. By using the method from the object, any unrecognized URLs are discarded and the application is redirected to a default location. In this instance, the application is configured to redirect to the root URL if the given URL does not match a defined state.

Now, with each application state defined, you can begin to turn your attention to building the .

Resolving Data with the Articles Service

The configuration for the article's state includes a value for the option. This object is configured to have a string value of set to the property (see Listing 1 for context). Providing a string to the object tells the framework to locate a service registered in the application and to resolve the service down to its final value. The is implemented to return a promise.

Here, the service is using the service to create a promise to return an array. In this instance, the values are hard-coded, but in a real-world context, you may need to access a remote server to provide the data. In any case, the service must be fully resolved before the router framework will pass execution to the associated controller. Therefore, as the article's state is invoked, ultimately the controller is passed an array of objects as a dependency.

Using Resolved Data in the ArticlesController

One of the advantages of using the UI Router framework is the ability to enforce separation of concerns. As the articles state implements a object, the raw array of articles is injected into the controller.

This approach is superior to requiring the to “know” about the because it's much easier to mock a raw array of objects for testing purposes rather dealing with mocking the service itself. The full implementation for the application's controllers is found in Listing 2.

Listing 2: Controllers

Rendering the Articles List

Now that the application has navigated to the article's state and the controller has the resolved array set into scope, the view is now ready to be rendered. The Articles view is made up of two parts. The first is another placeholder that uses the directive in order to create a nested view. The second is an unordered list of the different articles available on the site. Constructing the view like this allows you to click on different article titles while the list of article remains on the page. (You can see an example of this in Figure 5.) This is possible because the contents of the page are loaded in to the article-level while the page as a whole is rendered in the in the application shell. The full implementation of the application shell is available in Listing 4.

Listing 4: HTML Shell

The following code snippet demonstrates how the articles view implements a nested view.

There are three ways this markup uses the UI Router framework. First, the element uses the directive as a placeholder, and, as the comment states, you can pass in default content to render in the placeholder before any content is rendered by the framework. Listing 5 demonstrates how a static message is used as placeholder content on the page before any content is loaded into the view.

Listing 5: Articles Partial

Second, the anchor element has the directive applied. This signals to the UI Router framework to process this link in the context of the framework and ultimately renders a standard value that matches the URL for the declared state based on the settings defined in the application configuration (see Listing 1).

The third way the framework is used is that the value of the directive accepts an expression to generate the correct URL value for a nested state. Here, a hash is passed into the nested state hierarchy (in this case ) where the value for is bound to the incoming article's . When the UI Router framework evaluates this expression, a corresponding URL value is generated for each article that matches the defined state rules.

More Abstract Navigation

The last controller to implement is the , which uses the state parameter's method to navigate the application to a new state.

Here, by simply calling with a state name, your controller is only concerned with declaring the state you wish to change to rather than trying to keep track of the concrete routing scheme in the application.

Conclusion

Although AngularJS comes stocked with a functional routing implementation, you can quickly realize the advantages of using a state-based routing framework for non-trivial applications. The UI Router framework provides easy ways for you to define states, resolve dependencies, and make use of nested views. For even more information on what the framework can do, make sure to visit the project's home on GitHub at https://github.com/angular-ui/ui-router.

To get hands-on experience with the code presented in this article, please go to http://craigshoemaker.github.io/angular-ui-router-demo/. The full source code is available on GitHub at https://github.com/craigshoemaker/angular-ui-router-demo.

The method's resolve option is quite flexible. If you set a property equal to a string, the framework resolves the service by the same name down to its final value. If you set a property equal to a function, the function is run and the final value of the function is injected into the associated controller. Each value defined in the object must finish resolving to its final value before the controller is instantiated.

The UI Router framework gives you ultimate control over the URLs generated for your site by allowing you to enable HTML5 mode. When enabled, this mode does not generate hash (#) locations, but uses the HTML5 history API to generate clean URLs. The only caveat to this approach is that you must build your application to work under each generated path, rather than just at the root, which is customary in most single-page applications.

Routing in Angular JS using Angular UI Router

AngularJS

Angular-UI-Router is an AngularJS module used to create routes for AngularJS applications. Routes are an important part of Single-Page-Applications (SPAs) as well as regular applications and Angular-UI-Router provides easy creation and usage of routes in AngularJS.

Angular-UI-Router has stateProvider method which is used to create routes/states in application. State Provider takes state name and state configurations as parameters.



Syntax:

$stateProvider .state('StateName', { url: 'Url pattern for this State', template: "Html content", controller: "Name of the Controller for this state" });

Instead of template, templateUrl can be used and given the path of the HTML file to render for the state.
Example:

$stateProvider .state('Home', { url: '/home', templateUrl: "home.html", controller: "HomeCtrl" });

Simple project to navigate between the routes to demonstrate the use of the Angular-UI-Router module.
Pre-requisites:Node.js and npm

To run and install http-server node module to host demo app.

Steps to perform the operation:
1. Create a directory structure as below:

routingDemo --app.js --index.html --nav.html

2. Create nav.html file as below. This file consist of nav bar title and contents of it.

3. Create index.html file as below. All the required dependencies are included in this file along with nav.html file and definition of ui-view where content of different routes will be rendered.

Explanation:

  • All the dependencies are included via CDN in the head tag.
  • nav.html file is included to the index.html page in the body tag
  • The last division in body defines ui-view div where the content of different routes will be rendered.

    Note:If it does not work, replace the second and third script with below:



    <script src="angular.min.js"></script> <script src = " https://unpkg.com/@uirouter/[email protected]/release/angular-ui-router.min.js"> </script>

    4. Create app.js file as below. This is the application file with routes information and actions to be performed through controller.

    5. To run the above demo app in the browser, install http-server node module. To install the http-server module use the following command:

    npm install http-server -g

    6. After Installing:
    –From routingDemo folder, run following command:

    http-server

    Above command will host the demo app on port 8080. app can be accessed using below link:

    localhost:8080/

    7. If this application is accessed via browser, Output will be as below:

    8. After clicking on Login tab in the nav bar, Output will be as below:

    9. Clicking on Sign up tab in the nav bar, Output will be as below:

    Three routes namely Home, Login and Sign up are created in this sample application.

    Applications:

  • Routes are important for Single Page applications as they provide different functionalities to the application on the same page.
  • Routes creation and manipulation is easy with the angular-ui-router module.

AngularJS UI-Router Tutorial - Working with Parameters

AngularJS Routing Using UI-Router

AngularJS provides a great way to make single page applications. When creating single page applications, routing will be very important. We want our navigation to feel like a normal site and still not have our site refresh. We've already gone through Angular routing using the normal ngRoute method.

Today we'll be looking at routing using UI-Router.

Overview

What is AngularUI Router?

The UI-Router is a routing framework for AngularJS built by the AngularUI team. It provides a different approach than ngRoute in that it changes your application views based on state of the application and not just the route URL.

States vs URL Route

With this approach, your views and routes aren't tied down to the site URL. This way, you can change the parts of your site using your routing even if the URL does not change.

When using ngRoute, you'd have to use ngInclude or other methods and this could get confusing. Now that all of your states, routing, and views are handled in your one , this would help when using a top-down view of your application.

Sample Application

Let's do something similar to the other routing tutorial we made. Let's create a Home and About page.

Setup

Let's get our application started. We will need a few files:

With our application structure figured out, let's fill out some files.

There's our HTML file. We will use Bootstrap to help with our styling. Notice that we also load up in addition to loading Angular. UI Router is separate from the Angular core, just like ngRoute is separate.

Get Started w/ JavaScriptfor free!

When creating a link with UI-Router, you will use . The href will be generated from this and you want this to point to a certain state of your application. These are created in your .

We also use instead of ngRoute's .

Let's start up our Angular application now in .

Now we have created the that we already applied to our in the file.

Here we have a for home and for about. In home, we are using the template file .

Let's fill out our page so we can actually see information.

Now we have our site! It doesn't do much, but we have it.

angular-ui-router-home-first With the boring normal stuff out of the way, let's get to see why UI-Router has some pretty cool features.

Nested Views Home Page

Let's look at how we can nest views. We'll add two buttons to our home page and from there, we will want to show off different information based on what is clicked.

We're going to add our buttons to and then go into our Angular file and see how we can change it to add nested views.

When linking to a nested view, we are going to use dot denotation: and . These will be defined in our Angular file and once we set it up there, we will inject into our new .

In our file, let's create those nested states.

Now the ui-sref we defined in are linked to an actual state. With and created, those links will now take the template provided and inject it into .

Last thing we need to do for the home page is define the file. We have also passed in a controller with a list of dogs that we will use in the template file.

Now when we click List, it will inject our list of dogs into the template. Or if we click Paragraph, it will inject the string we gave.

angular-routing-ui-router-home-list You can see how easy it is to change different parts of our application based on the state. We didn't have to do any sort of work with ngInclude, ngShow, ngHide, or ngIf. This keeps our view files cleaner since all the work is in our .

Let's move on and see how we can have multiple views at once.

Multiple Views About Page

Having multiple views in your application can be very powerful. Maybe you have a sidebar on your site that has things like Popular Posts, Recent Posts, Users, or whatever. These can all be separated out and injected into our template. Each will have its own controller and template file so our app stays clean.

Having our application modular like this also lets us reuse data in different templates.

For our About page, let's make two columns and have each have its own data. We will handle the view first and then look at how we can do this using UI-Router.

There we have multiple views. One is named and the other is .

Why would somebody use this approach? That's a good question. Are we creating an application that is too modularized and that could get confusing? Taken from the official UI-Router docs, here is a solid example of why you would have multiple named views. In their example, they show off different parts of an application. Each part has its own data, so having each with its own controllers and template files makes building something like this easy.

Now that our view is all created, let's look at how we can apply template files and controllers to each view. We'll go back to our .

angular-routing-ui-router-about Just like that, our About page is ready to go. Now it may be confusing how we nested everything in the for the about state. Why not define a templateUrl for the main page and then define the columns in a nested view object? The reason for this gives us a really great tool.

Relative vs Absolute Naming

UI-Router assigns every view to an absolute name. The structure for this is . Since our main inside our about state, we gave it a blank name. The other two views because and .

Having the naming scheme this way let's us define multiple views inside a single state. The docs explain this concept very well and I'd encourage taking a look at their examples. Extremely powerful tools there.

Conclusion

This is an overview of the great tool that is UI-Router. The things you can do with it are incredible and when you look at your application as states instead of going the ngRoute option, Angular applications can easily be created to be modular and extensible.
