<div class="lead">
<p>A function used to lazy load code</p>
</div>
<p>The <code>lazyLoad</code> function is invoked before the state is activated.
The transition waits while the code is loading.</p>
<p>The function should load the code that is required to activate the state.
For example, it may load a component class, or some service code.
The function must return a promise which resolves when loading is complete.</p>
<p>For example, this code lazy loads a service before the <code>abc</code> state is activated:</p>
<pre><code>.<span class="hljs-keyword">state</span>('abc', {
lazyLoad: (transition, <span class="hljs-keyword">state</span>) => System.import('./abcService')
}
</code></pre><p>The <code>abcService</code> file is imported and loaded
(it is assumed that the <code>abcService</code> file knows how to register itself as a service).</p>
<h4 id="lifecycle">Lifecycle</h4>
<ul>
<li>The <code>lazyLoad</code> function is invoked if a transition is going to enter the state.</li>
<li>The function is invoked before the transition starts (using an <code>onBefore</code> transition hook).</li>
<li>The function is only invoked once; while the <code>lazyLoad</code> function is loading code, it will not be invoked again.
For example, if the user double clicks a ui-sref, <code>lazyLoad</code> is only invoked once even though there were two transition attempts.
Instead, the existing lazy load promise is re-used.</li>
<li>When the promise resolves successfully, the <code>lazyLoad</code> property is deleted from the state declaration.</li>
<li>If the promise resolves to a <a href="state.lazyloadresult.html">LazyLoadResult</a> which has an array of <code>states</code>, those states are registered.</li>
<li><p>The original transition is retried (this time without the <code>lazyLoad</code> property present).</p>
</li>
<li><p>If the <code>lazyLoad</code> function fails, then the transition also fails.
The failed transition (and the <code>lazyLoad</code> function) could potentially be retried by the user.</p>
</li>
</ul>
<h3 id="lazy-loading-state-definitions-future-states-">Lazy loading state definitions (Future States)</h3>
<p>State definitions can also be lazy loaded.
This might be desirable when building large, multi-module applications.</p>
<p>To lazy load state definitions, a Future State should be registered as a placeholder.
When the state definitions are lazy loaded, the Future State is deregistered.</p>
<p>A future state can act as a placeholder for a single state, or for an entire module of states and substates.
A future state should have:</p>
<ul>
<li>A <code>name</code> which ends in <code>.**</code>.
A future state's <code>name</code> property acts as a wildcard <a href="../classes/core.glob.html">Glob</a>.
It matches any state name that starts with the <code>name</code> (including child states that are not yet loaded).</li>
<li>A <code>url</code> prefix.
A future state's <code>url</code> property acts as a wildcard.
UI-Router matches all paths that begin with the <code>url</code>.
It effectively appends <code>.*</code> to the internal regular expression.
When the prefix matches, the future state will begin loading.</li>
<li>A <code>lazyLoad</code> function.
This function should should return a Promise to lazy load the code for one or more <a href="state.statedeclaration.html">StateDeclaration</a> objects.
It should return a <a href="state.lazyloadresult.html">LazyLoadResult</a>.
Generally, one of the lazy loaded states should have the same name as the future state.
The new state will then <strong>replace the future state placeholder</strong> in the registry.</li>
</ul>

<p>Normally, a state's parent is implied from the state's <a href="state.statedeclaration.html#name">name</a>, e.g., <code>"parentstate.childstate"</code>.</p>
<p>Alternatively, you can explicitly set the parent state using this property.
This allows shorter state names, e.g., <code><a ui-sref="childstate">Child</a></code>
instead of `<a ui-sref="parentstate.childstate">Child</a></p>
<p>When using this property, the state's name should not have any dots in it.</p>

<p>Resolve - a mechanism to asynchronously fetch data, participating in the Transition lifecycle</p>
</div>
<p>The <code>resolve:</code> property defines data (or other dependencies) to be fetched asynchronously when the state is being entered.
After the data is fetched, it may be used in views, transition hooks or other resolves that belong to this state.
The data may also be used in any views or resolves that belong to nested states.</p>
<h3 id="as-an-array">As an array</h3>
<p>Each array element should be a <a href="resolve.resolvableliteral.html">ResolvableLiteral</a> object.</p>
<h4 id="example-">Example:</h4>
<p>The <code>user</code> resolve injects the current <code>Transition</code> and the <code>UserService</code> (using its token, which is a string).
The [[ResolvableLiteral.resolvePolicy]] sets how the resolve is processed.
The <code>user</code> data, fetched asynchronously, can then be used in a view.</p>
<pre><code class="lang-js">var state = {
name: 'user',
url: '/user/:userId
resolve: [
{
token: 'user',
policy: { when: 'EAGER' },
deps: ['UserService', Transition],
resolveFn: (userSvc, trans) => userSvc.fetchUser(trans.params().userId) },
}
]
}
</code></pre>
<p>Note: an Angular 2 style <a href="https://angular.io/docs/ts/latest/cookbook/dependency-injection.html#!#provide"><code>useFactory</code> provider literal</a>
may also be used. See <a href="resolve.providerlike.html">ProviderLike</a>.</p>
<h4 id="example-">Example:</h4>
<pre><code><span class="hljs-string">resolve:</span> [
{ <span class="hljs-string">provide:</span> <span class="hljs-string">'token'</span>, <span class="hljs-string">useFactory:</span> (http) => http.get(<span class="hljs-string">'/'</span>), <span class="hljs-string">deps:</span> [ Http ] },
]
</code></pre><h3 id="as-an-object">As an object</h3>
<p>The <code>resolve</code> property may be an object where:</p>
<ul>
<li>Each key (string) is the name of the dependency.</li>
<li>Each value (function) is an injectable function which returns the dependency, or a promise for the dependency.</li>
</ul>
<p>This style is based on AngularJS injectable functions, but can be used with any UI-Router implementation.
If your code will be minified, the function should be <a href="https://docs.angularjs.org/guide/di#dependency-annotation">"annotated" in the AngularJS manner</a>.</p>
<h4 id="angularjs-example-">AngularJS Example:</h4>
<pre><code class="lang-js">resolve: {
<span class="hljs-comment">// If you inject `myStateDependency` into a controller, you'll get "abc"</span>
myStateDependency: <span class="hljs-function"><span class="hljs-keyword">function</span>(<span class="hljs-params"></span>) </span>{
<span class="hljs-keyword">return</span> <span class="hljs-string">"abc"</span>;
},
<span class="hljs-comment">// Dependencies are annotated in "Inline Array Annotation"</span>
myAsyncData: [<span class="hljs-string">'$http'</span>, <span class="hljs-string">'$transition$'</span> <span class="hljs-function"><span class="hljs-keyword">function</span>(<span class="hljs-params">$http, $transition$</span>) </span>{
<span class="hljs-comment">// Return a promise (async) for the data</span>
<span class="hljs-keyword">return</span> $http.get(<span class="hljs-string">"/foos/"</span> + $transition$.params().foo);
}]
}
</code></pre>
<p>Note: You cannot specify a policy for each Resolvable, nor can you use non-string
tokens when using the object style <code>resolve:</code> block.</p>
<h3 id="lifecycle">Lifecycle</h3>
<p>Since a resolve function can return a promise, the router will delay entering the state until the promises are ready.
If any of the promises are rejected, the Transition is aborted with an Error.</p>
<p>By default, resolves for a state are fetched just before that state is entered.
Note that only states which are being <em>entered</em> during the <code>Transition</code> have their resolves fetched.
States that are "retained" do not have their resolves re-fetched.</p>
<p>If you are currently in a parent state <code>parent</code> and are transitioning to a child state <code>parent.child</code>, the
previously resolved data for state <code>parent</code> can be injected into <code>parent.child</code> without delay.</p>
<p>Any resolved data for <code>parent.child</code> is retained until <code>parent.child</code> is exited, e.g., by transitioning back to the <code>parent</code> state.</p>
<p>Because of this scoping and lifecycle, resolves are a great place to fetch your application's primary data.</p>
<h3 id="injecting-resolves-into-other-things">Injecting resolves into other things</h3>
<p>During a transition, Resolve data can be injected into:</p>
<ul>
<li>Views (the components which fill a <code>ui-view</code> tag)</li>
<li>Transition Hooks</li>
<li>Other resolves (a resolve may depend on asynchronous data from a different resolve)</li>
</ul>
<h3 id="injecting-other-things-into-resolves">Injecting other things into resolves</h3>
<p>Resolve functions usually have dependencies on some other API(s).
The dependencies are usually declared and injected into the resolve function.
A common pattern is to inject a custom service such as <code>UserService</code>.
The resolve then delegates to a service method, such as <code>UserService.list()</code>;</p>
<h4 id="special-injectable-tokens">Special injectable tokens</h4>
<ul>
<li><code>UIRouter</code>: The <a href="ng1.__uirouter_core_lib_router_.uirouter.html">UIRouter</a> instance which has references to all the UI-Router services.</li>
<li><code>Transition</code>: The current <a href="../classes/transition.transition-1.html">Transition</a> object; information and API about the current transition, such as
"to" and "from" State Parameters and transition options.</li>
<li><code>'$transition$'</code>: A string alias for the <code>Transition</code> injectable</li>
<li><code>'$state$'</code>: For <code>onEnter</code>/<code>onExit</code>/<code>onRetain</code>, the state being entered/exited/retained.</li>
<li>Other resolve tokens: A resolve can depend on another resolve, either from the same state, or from any parent state.</li>
