UI Router Web Component wrapper (using minimal bits from Polymer 3.x base element)

Use https://ui-router.github.io/core/docs/latest/ and https://ui-router.github.io/ For general UI-Router documentation.

UI-Router is one of most popular routing solutions, with ports for angular 1.x, 2.x+ and react - now also available for Web Components.

UI-Router provides state based routing. Each feature of an application is defined as a state. One state is active at any time, and UI-Router manages the transitions between the states.

Each state describes the URL, the UI (a view or views), data prerequisites, and other logical prerequisites (such as authentication) for a feature. Before activating a state, UI-Router first fetches any prerequisites (asynchronously), and then activates the view(s) and updates the URL.

UI-Router states are hierarchical; states can be nested inside other states, forming a tree. Child states may inherit data and behavior (such as authentication) from their parent states.

Some features of UI Router:

• Hierarchical states both abstract and components based
• States can be resolve (including async) and activate based on set prerequisites
• Multiple views per state
• Views can be nested inside other views
• Transition and lifecycle API's

Example usage

let routerStates = [
   {name: "index_route", url: "/index", component: "index-comp"},
   {name: "foo", url: "/foo", component: "foo-comp"},
   {name: "arg", url: "/arg/:argumentId?:test", component: "arguments-comp"},
   {name: "user", url: "/bar", component: "bar-comp"},
   {name: "state_a", parent: 'bar.baz', url: "/a", component: "baz-a-comp"},
   {name: "state_b", parent: 'bar.baz', url: "/b", component: "baz-b-comp"}
   ]
// top-level
<uirouter-router id="ui-router" states="[[routerStates]]" auto-start>
</uirouter-router>

// view level, generates A tags
<uirouter-sref state="foo" reload>Foo (this restomps every click)</uirouter-sref>
<uirouter-sref state="arg" param-argument-id="99">
    With arguments directly
</uirouter-sref>

// this injects new views based on router state, /index path will 
// result in <index-comp/> being stomped
<uirouter-uiview></uirouter-uiview>

Install the Polymer-CLI

First, make sure you have the Polymer CLI installed.

Install bower and npm dependencies (quick way is yarn bower).

Then run yarn serve to serve your application locally.

TIPS

Set a <base href="$path"> tag in your index.html to let the router know the static/base part of your URL
