What it is
UI-Router is a client-side routing framework for AngularJS, the older 1.x version of Angular. It keeps the browser URL in sync with what the app is showing, so a user can bookmark a deep page inside a single-page app. Apps are organized as a tree of named states, and the library manages moving between them as a state machine.
- Map URLs such as product pages to nested app states with their own views
- Let a browser back or forward action move through application states
- Create bookmarkable links to specific screens deep inside a single-page app
Great for
- Teams maintaining an existing AngularJS 1.x application
- Developers who need nested views that follow URL structure
- Apps where deep-linkable, bookmarkable pages matter
Not ideal for
- New projects: the README points newer work to separate UI-Router versions for Angular 2 and React, so this 1.x package targets AngularJS specifically
- Projects still on UI-Router 0.x, which the README says lives on a separate legacy branch
- Non-developers, since it is a code library with no standalone interface
How to get it
- 1
Install with a package manager
You'll need: AngularJS 1.x application
Clone the repository
git clone https://github.com/angular-ui/ui-router - 2
Run it
- Read the Get Started tutorial for UI-Router for Angular 1 linked in the README
- Include the library in your AngularJS page or build, as described in the guide
- Define your first state with a URL and a view
- Navigate to that URL in the browser to confirm the view loads
- 3
Get the most out of it
- Use the in-depth guide on the project wiki for advanced state configuration
- Consult the API docs for the full list of state and transition options
- Check the FAQ on the wiki when you hit common questions
- Look at the linked sample app to see a working example of nested states
Downloads
Strengths
- Built around a hierarchical state tree that maps cleanly to nested views
- URL and app state stay in sync, which supports bookmarks and shareable links
- Includes tutorials, API docs, and a sample app linked from the README
Trade-offs
- Targets AngularJS 1.x, an older framework; the README does not describe a migration path within this package
- The README is truncated and gives little detail on installation or configuration here
- Learning the state-machine model takes time for developers new to it
