`{{mount}}` lazy loading route-less engines.
## Compatibility
- Ember.js v4.12 or above
- Embroider or ember-auto-import v2
## Installation
```
ember install ember-lazy-mount
```
## Usage
### `{{lazy-mount}}` Component
- **`name`**: _`string`_ — The name of the engine to load
- **`model?`**: _`any`_ — Optional model that will be passed through to the engine
The `{{lazy-mount}}` component works just like the [`{{mount}}` helper](https://emberjs.com/api/ember/3.5/classes/Ember.Templates.helpers/methods/mount?anchor=mount).
It accepts the name of the engine as a positional parameter and also an optional
`model` parameter.
As soon as the helper is rendered, it will begin loading the specified engine.
If the engine is already loaded, it will be mounted immediately.
The `engineName` and `model` parameters are dynamic and you can update them.
Setting a new `engineName` will cause the new engine to be loaded and mounted.
#### Inline Usage
While the engine is loading, nothing is rendered. If there was an error loading
the engine, nothing is rendered.
```hbs
{{lazy-mount engineName model=optionalDataForTheEngine}}
```
You can also pass three optional hooks:
```hbs
{{lazy-mount
this.engineName
onLoad=this.onLoad
didLoad=this.didLoad
onError=this.onError
}}
```
- **`onLoad()`** — Called when the engine starts loading
- **`didLoad()`** — Called when the engine loaded successfully
- **`onError(error: Error)`** — Called when the engine failed to load
#### Block Usage
While the engine is loading or if there was an error loading the engine, the
block that is passed to the component is rendered. The `engine` block parameter
is an object with two properties:
- **`isLoading`**: _`boolean`_ — Whether or not the engine is currently loading
- **`error`**: _`Error | null`_ — If there was an error loading the engine
When the engine was loaded successfully, the passed in block is replaced by the
engine.
```hbs
{{#lazy-mount engineName model=optionalDataForTheEngine as |engine|}}
{{#if engine.isLoading}}
🕑 The engine is loading...
{{else if engine.error}}
😨 There was an error loading the engine:
{{engine.error}}
{{/if}}
{{/lazy-mount}}
```
You can also pass in the same hooks: `onLoad`, `didLoad`, `onError`
