## Package Requirements
Make sure you have the required packages installed:
```
iron:router
fourseven:scss
meteoric:ionic-sass
meteoric:ionicons-sass
meteoric:ionic
```
## Blaze Templates
`meteor-ionic` makes extensive use of Blaze Templates. There are two ways to include a Blaze Template into your page: inclusion syntax and block syntax.
### Inclusion Syntax
Most Meteor developers are already familiar with the inclusion syntax which takes a template like this:
```
<template name="myTemplate">
<div class="my-template">
Static content here
</div>
</template>
```
And lets you include it in another template like this:
```
<h1>Another Template</h1>
{{> myTemplate}}
```
Which outputs this:
```
<h1>Another Template</h1>
<div class="my-template">
Static content here
</div>
```
### Block Helpers
The block syntax (also called block helpers) is much more interesting. A block helper allows us to create a "wrapper" template like so:
```
<template name="myTemplate">
<div class="my-template">
{{> UI.contentBlock}}
</div>
</template>
```
And inject custom content into it when we include it on the page:
```
<h1>Another Template</h1>
{{#myTemplate}}
Custom content goes here
{{/myTemplate}}
```
Which outputs this:
```
<h1>Another Template</h1>
<div class="my-template">
Custom content goes here
</div>
```
### `meteor-ionic` Components
`meteor-ionic` uses these "block helpers" to mimic Angular's "directives" feature which is prevalent in Ionic. There are a few reasons for this:
#### 1. Convenience
Some components may require several `<div>`'s or class names which can be difficult to remember. These can be abstracted away into the wrapper template allowing you to simply type a component name such as `{{#ionContent}}`.
#### 2. Configuration options
Using block helpers we can pass simple options to our template (e.g. `align='left'`, `title='My Modal'`) and let the template convert those options into CSS classes or HTML content.
For example a fictional `myPanel` component could be initialized like this:
```
{{#myPanel title="Meteoric" type="primary"}}
<p>Meteor + Ionic = Meteoric</p>
{{/myPanel}}
```
And could then output:
```
<div class="my-panel is-primary">
<div class="my-panel-header">
<h1>Meteoric</h1>
</div>
<div class="my-panel-body">
<p>Meteor + Ionic = Meteoric</p>
</div>
</div>
```
#### 3. Advanced Functionality
Some of the more advanced components like `ionNavView`, `ionNavBar`, `ionModal`, etc provide full HTML structures, events and animations all with a single template include.
## Layout Structure
### ionBody
All meteor-ionic apps must have an `ionBody` component at the root. This element has various classes and event handlers attached to it. In your `iron:router` layout, make sure you have an `ionBody` component surrounding your `{{>yield}}`:
```
{{#ionBody}}
{{>yield}}
{{/ionBody}}
```
### ionContent
You will almost always want to wrap your templates in an `ionContent` component. The `ionContent` has two primary responsibilities:
1. Implements native-feeling scrolling on the device using `-webkit-overflow-scrolling: touch;`
2. Positions itself appropriately from the top or bottom of the screen when headers, footers and tabs are present.
Most of your templates will follow this pattern:
```
{{#ionContent}}
<p>Your content here</p>
{{/ionContent}}
```
Which will output:
```
<div class="scroll-content ionic-scroll">
<div class="content overflow-scroll">
<p>Your content here</p>
</div>
</div>
```
The `ionContent` component also accepts arbitrary CSS classes. For example, to use Ionic's built in `padding` class to add padding around your content, you can do:
```
{{#ionContent class="padding"}}
<p>Your content here</p>
{{/ionContent}}
```
Which would output:
```
<div class="scroll-content ionic-scroll">
<div class="content overflow-scroll padding">
<p>Your content here</p>
</div>
</div>
```
## Navigation Stacks
To mimic the sliding-back-and-forth navigation UI of mobile apps, meteor-ionic makes use of the three primary technologies:
- `iron:router`
- `iron:layout`
- Meteor's `_uihooks`
#### Layout
As previously mentioned, your layout should have an `ionBody` component at the root. Inside of this you will want to wrap your `yield` in an `ionNavView`, which will take care of animating the templates that `iron:router` renders. Lastly, you'll probably want an `ionNavBar` element at the top of your screen to show the title of the page, as well as navigation items and other action buttons.
```
{{#ionBody}}
{{> ionNavBar}}
{{#ionNavView}}
{{> yield}}
{{/ionNavView}}
{{/ionBody}}
```
#### Templates
In the individual templates that get rendered in the navigation stack, you will want to follow this pattern:
```
{{#contentFor "headerButtonLeft"}}
{{>ionNavBackButton}}
{{/contentFor}}
{{#contentFor "headerTitle"}}
<h1 class="title">Notifications</h1>
{{/contentFor}}
{{#ionView}}
{{#ionContent}}
Content goes here
{{/ionContent}}
{{/ionView}}
```
The `ionView` component simply adds some CSS rules that allow it to be animated properly and the `ionContent` component should look familiar by now. However the `contentFor` blocks probably need some explaining:
### ionNavBar
This is where `iron:layout` comes into play. Our `ionNavBar` component exposes three "regions" that you can insert content into: "headerButtonLeft", "headerButtonRight" and "headerTitle". Whatever content you put inside the `contentFor` block will get inserted (and in this case, animated) into the correct region.
## Tabs
TODO
## Modals
The `ionModal` component is quite easy to implement. First, create a template for your modal:
```
<template name="myModal">
{{#ionModal title="My Modal"}}
<p>My modal content goes here</p>
{{/ionModal}}
</template>
```
Then attach it to a `button` or `a` element by passing in the name of the template to the `data-ion-modal` attribute.
```
<button data-ion-modal="myModal">Open Modal</button>
```
