# Ember Collection
[](https://github.com/adopted-ember-addons/ember-collection/actions?query=workflow%3ACI)
[](http://emberobserver.com/addons/ember-collection)
An efficient incremental rendering component with support for custom layouts and large lists.
### Table of Contents
1. [Installation](#installation)
1. [Usage](#usage)
1. [Layouts](#layouts)
1. [Build it](#build-it)
1. [How it works](#how-it-works)
1. [Run unit tests](#running-unit-tests)
## Installation
* `ember install ember-collection`
## Submitting bugs
Create a reproduction of the bug in https://ember-twiddle.com/
It would help us greatly to help you and to improve ember collection.
## Usage
The height of the collection is inferred from its nearest relative parent.
This is so you can just use CSS to style the container.
So, first make sure the collection has a parent with `position: relative`, and
then render a template:
```handlebars
{{#ember-collection
items=model
cell-layout=(fixed-grid-layout 800 50) as |item index|
}}
{{item.name}}
{{/ember-collection}}
```
Next, let's feed our template with some data:
``` javascript
// define index route and return some data from model
export default Ember.Route.extend({
model: function() {
var items = [];
for (var i = 0; i < 10000; i++) {
items.push({name: "Item " + i});
}
return items;
}
});
```
Shazam! You should be able to see a scrollable area with 10,000 items in it.
### Required parameters
You must specify `cell-layout` parameter so that *EmberCollection* can layout out your items. The provided layouts are described in the [Layouts](#layouts) section.
### Estimating width/height
You can pass `estimated-width` and `estimated-height` to the collection, for situations where the collection cannot infer its height from its parent (e.g., when there's no DOM in FastBoot).
Once the collection has been rendered, `estimated-width` and `estimated-height` have no effect.
### Actions
#### scroll-change
If you do not provide a `scroll-change` action name or closure action, scrolling will work normally.
If you *do* specify `scroll-change`, ember-collection assumes that you want to handle the scroll-change action in a true data down, actions up manner. For this reason, ember-collection will not set `scroll-left` and `scroll-top` itself, but rather rely on you to update those properties based on action handling as you see fit.
An example of specifying an action and keeping scrolling working normally looks like this:
```hbs
{{#ember-collection items=model cell-layout=(fixed-grid-layout itemWidth itemHeight)
scroll-left=scrollLeft scroll-top=scrollTop scroll-change=(action "scrollChange")
as |item index| }}
<div class="list-item">{{item.name}}</div>
{{/ember-collection}}
```
```js
export default Ember.Controller.extend({
scrollLeft: 0,
scrollTop: 0,
actions: {
scrollChange(scrollLeft, scrollTop) {
this.set('scrollLeft', scrollLeft);
this.set('scrollTop', scrollTop);
}
}
});
```
## Layouts
### Fixed Grid Layout
The `fixed-grid-layout` will arrange the items in a grid to to fill the content area. The arguments for the layout are:
| Argument | Description |
| ------------ | --------------------------- |
| `itemWidth` | The width of each item |
| `itemHeight` | The height of each item |
```hbs
{{#ember-collection items=model cell-layout=(fixed-grid-layout itemWidth itemHeight)
scroll-left=scrollLeft scroll-top=scrollTop scroll-change=(action "scrollChange")
as |item index| }}
<div class="list-item">{{item.name}}</div>
{{/ember-collection}}
```
### Mixed Grid Layout
The `mixed-grid-layout` is used when each item has a known `width` and `height` and will arrange the items in rows from left to right fitting as many items in each row as possible. The arguments for the layout are:
| Argument | Description |
| ----------- | --------------------------- |
| `itemSizes` | A collection of objects having `width` and `height` properties. Used to lookup with size of the corresponding index in the collection. |
For example if you want the first element in `items` to have a size of `20x50` then the first element in `itemSizes` must be `{width: 20, height: 50}`. If the items have `width` and `height` properties you can use pass collection to `items` and `itemSizes`.
```hbs
{{#ember-collection items=model cell-layout=(mixed-grid-layout itemSizes)
scroll-left=scrollLeft scroll-top=scrollTop scroll-change=(action "scrollChange")
as |item index| }}
<div class="list-item">{{item.name}}</div>
{{/ember-collection}}
```
### Percentage Columns Layout
The `percentage-columns-layout` allows items to be laid out in a fixed number of columns sized using percentage widths with a fixed height in pixels. The arguments for the layout are:
| Argument | Description |
| ------------ | -------------------------------------------------------------------------------------------------------------- |
| `itemCount` | The number of items passed to the collection. This is usually the number of items in the model (`model.length`). |
| `columns` | An array of numbers not totaling more than 100. e.g. `[33.333, 66.666]`, `[25, 50, 10, 15]` |
| `itemHeight` | The height in pixels of each item. |
```hbs
{{#ember-collection items=model cell-layout=(percentage-columns-layout itemCount columns itemHeight)
scroll-left=scrollLeft scroll-top=scrollTop scroll-change=(action "scrollChange")
as |item index| }}
<div class="list-item">{{item.name}}</div>
{{/ember-collection}}
```
### Creating your own layout
If none of the built in layouts included with *EmberCollection* fit your needs you can create your own. A layout is simply an object returned from a helper that conforms to the following interface.
```js
import Ember from 'ember'
export default Ember.Helper.helper(function(params, hash) {
return {
/**
* Return an object that describes the size of the content area
*/
contentSize(clientWidth, clientHeight) {
return { width, height };
}
/**
* Return the index of the first item shown.
*/
indexAt(offsetX, offsetY, clientWidth, clientHeight) {
return Number;
}
/**
* Return the number of items to display
*/
count(offsetX, offsetY, width, height) {
return Number;
}
/**
* Return the css that should be used to set the size and position of the item.
*/
formatItemStyle(itemIndex, clientWidth, clientHeight) {
return String;
}
}
});
```
## Build It
1. `git clone https://github.com/adopted-ember-addons/ember-collection.git`
2. `cd ember-collection`
3. `npm install`
5. `ember build`
## How it works
*EmberCollection* will create enough rows to fill the visible area. It reacts to scroll events and reuses/repositions the rows as scrolled.
## Running unit tests
```sh
npm install
npm test
```

FILE: RELEASE.md
================================================
# Release
Releases are mostly automated using
[release-it](https://github.com/release-it/release-it/) and
[lerna-changelog](https://github.com/lerna/lerna-changelog/).
## Preparation
Since the majority of the actual release process is automated, the primary
remaining task prior to releasing is confirming that all pull requests that
have been merged since the last release have been labeled with the appropriate
`lerna-changelog` labels and the titles have been updated to ensure they
represent something that would make sense to our users. Some great information
on why this is important can be found at
[keepachangelog.com](https://keepachangelog.com/en/1.0.0/), but the overall
guiding principle here is that changelogs are for humans, not machines.
When reviewing merged PR's the labels to be used are:
* breaking - Used when the PR is considered a breaking change.
* enhancement - Used when the PR adds a new feature or enhancement.
* bug - Used when the PR fixes a bug included in a previous release.
* documentation - Used when the PR adds or updates documentation.
* internal - Used for internal changes that still require a mention in the
changelog/release notes.
## Release
Once the prep work is completed, the actual release is straight forward:
* First ensure that you have `release-it` installed globally, generally done by
using one of the following commands:
```
# using https://volta.sh
volta install release-it
# using Yarn
yarn global add release-it
# using npm
npm install --global release-it
```
* Second, ensure that you have installed your projects dependencies:
```
yarn install
```
* And last (but not least 😁) do your release. It requires a
[GitHub personal access token](https://github.com/settings/tokens) as
`$GITHUB_AUTH` environment variable. Only "repo" access is needed; no "admin"
or other scopes are required.
```
export GITHUB_AUTH="f941e0..."
release-it
```
[release-it](https://github.com/release-it/release-it/) manages the actual
release process. It will prompt you to to choose the version number after which
you will have the chance to hand tweak the changelog to be used (for the
`CHANGELOG.md` and GitHub release), then `release-it` continues on to tagging,
pushing the tag and commits, etc.

<div class="col-md-3">
<h2>Fixed Grid Layout</h2>
<p>Use the <code>fixed-grid-layout</code> when all items are the same size. The width and height of each item are bound as is the width and height of the container. Ember collection will re-layout items when any of these items change.</p>
<p><LinkTo @route="simple" class="btn btn-default">Demo</LinkTo></p>
</div>
<div class="col-md-3">
<h2>Mixed Grid Layout</h2>
<p>Use the <code>mixed-grid-layout</code> when items can be a different size. The collection being itterated over is passed to the <code>mixed-grid-layout</code> helper. Each item in the collection must provide a <code>width</code> and <code>height</code> property of the item.</p>
<p><LinkTo @route="mixed" class="btn btn-default">Demo</LinkTo></p>
</div>
<div class="col-md-3">
<h2>Scroll Position</h2>
<p>Use the <code>scroll-top</code> and <code>scroll-left</code> attributes to programtically scroll to a specific location in the collection. This can also be used to set an initial scroll position.</p>
<p><LinkTo @route="scroll-position" class="btn btn-default">Demo</LinkTo></p>
</div>
<div class="col-md-3">
<h2>Percentage Columns</h2>
<p>Use the <code>percentage-columns-layout</code> to render a fixed number of columns that are sized using percentages. The <code>columns</code> paramter should be an array of integers that add to 100.</p>
