Angular UI Router

Introduction

A potent client-side routing framework for AngularJS is called Angular UI Router. It offers a method for controlling and navigating between several views in a single-page web application. In addition to offering numerous sophisticated capabilities like nested states, multiple named views, and hierarchical URL routing, UI Router provides an alternative to Angular’ s built-in Ng Route module. States, which stand in for a particular view and its accompanying functionality, serve as the fundamental building elements of the UI Router. The URL, template, and controller may all be unique for each state. Additionally, states may be nested, enabling intricate navigational hierarchies.

State inheritance, which enables child states to inherit attributes from their parent states, and the capability to create numerous named views inside a single state are further capabilities offered by UI Router. This gives designers greater freedom when creating intricate user interfaces. The ability of UI Router to handle intricate URL routing is one of its main advantages. State parameters, which enable dynamic routing depending on user input, are used to do this. It is simple to move between stages using URLs because to UI Router's robust URL matching and URL creation capabilities.

UI Router is compatible with AngularJS 1.x, and UI-Router for Angular, a version for Angular 2+, is also offered. It is an open-source project that a group of developers are actively maintaining.

Applications

• States: States serve as the foundation of UI Router. They represent views and the functionality that goes along with them, and they may be nested to build intricate view hierarchies. Each state may provide its own set of parameters that may be used for dynamic routing, as well as its own URL, template, and controller.

• Multiple named views: Multiple named views can be defined within a single state using UI Router. This offers a technique to construct intricate user interfaces with several views that may be independently updated.

• State inheritance: A higher level in the state hierarchy may be defined by defining common behavior and functionality in child states, which can inherit characteristics from their parent states.

• URL routing: Strong URL routing features, such as URL creation and URL matching, are offered by UI Router. This makes it simple to manage sophisticated routing situations depending on user input and to travel between stages using URLs.

• Resolves: Before a state is activated, resolves provide a way to retrieve data or carry out other operations. This enables you to manage faults or other exceptions that may arise during the data retrieval process and verify that all relevant data is accessible before showing a view.

• Interceptors: Utilizing interceptors allows you to change requests and responses before the application sends or receives them. For managing authentication, caching, or other unique logic, this can be helpful.

• Transitions: States are activated or deactivated via the use of transitions. You may create custom behavior for transitions, including animations and other effects, using the robust transition framework provided by UI Router.

Overall, Angular UI Router is a strong and adaptable routing framework that offers a wealth of sophisticated functionality for creating complicated single-page AngularJS apps. It is a popular option for creating expansive and complicated applications because to its support for layered states, many named views, and state inheritance.

Features

• UI-Router for Angular 2+: As previously indicated, "UI-Router for Angular" is the name of the UI Router extension for Angular 2+. It has its own set of features and advantages and offers functionality that is comparable to the AngularJS version.

• Modular architecture: Because of its modular nature, UI Router's functionality may be readily expanded and altered. Adding features like slow loading, internationalization, and analytics is possible with third-party modules.

• UI-Router Extras: Sticky states, deep state redirect, and future states are just a few of the extra tools and features included with UI-Router Extras. Advanced capability for handling intricate routing circumstances is offered by these features.

• Compatibility with ngRoute: The ngRoute module that comes with Angular may be swapped out with UI Router. If you are currently using ngRoute, switching to UI Router is simple and doesn't require rewriting your whole application.

• Active development: With a sizable and engaged development community, UI Router is an actively maintained project. Issues and pull requests are actively examined and dealt with, and new features and bug fixes are often issued.
