## Collect statistics on the use of open source

TOAST UI Tree applies Google Analytics (GA) to collect statistics on the use of open source, in order to identify how widely TOAST UI Tree is used throughout the world.
It also serves as important index to determine the future course of projects.
`location.hostname` (e.g. > “ui.toast.com") is to be collected and the sole purpose is nothing but to measure statistics on the usage.
To disable GA, use the following `usageStatistics` option when creating the instance.

```js
const options = {
 ...
 usageStatistics: false
}
const instance = new Tree(container, options);
```

Or, include [`tui-code-snippet`](https://github.com/nhn/tui.code-snippet)(**v2.3.0** or **later**) and then immediately write the options as follows:

```js
tui.usageStatistics = false;
```

## 💾 Install

TOAST UI products can be used by using the package manager or downloading the source directly.
However, we highly recommend using the package manager.

### Via Package Manager

TOAST UI products are registered in the package manager, [npm](https://www.npmjs.com/).
You can conveniently install it using the commands provided by each package manager.
When using npm, be sure to use it in the environment [Node.js](https://nodejs.org/ko/) is installed.

#### npm

```sh
$ npm install --save tui-tree # Latest version
$ npm install --save tui-tree@<version> # Specific version
```

### Via Contents Delivery Network (CDN)

TOAST UI products are available over the CDN powered by [TOAST Cloud](https://www.toast.com).

You can use the CDN as below.

```html
<script src="https://uicdn.toast.com/tui-tree/latest/tui-tree.js"></script>
<link
  rel="stylesheet"
  type="text/css"
  href="https://uicdn.toast.com/tui-tree/latest/tui-tree.css"
/>
```

If you want to use a specific version, use the tag name instead of `latest` in the url's path.

The CDN directory has the following structure.

```
tui-tree/
├─ latest/
│  ├─ tui-tree.css
│  ├─ tui-tree.js
│  ├─ tui-tree.min.css
│  └─ tui-tree.min.js
├─ v3.3.0/
│  ├─ ...
```

### Download Source Files

- [Download bundle files and all sources for each version](https://github.com/nhn/tui.tree/releases)

## 🔨 Usage

### HTML

Add the container element to create the component. A wrapper element should have `tui-tree-wrap` as a class name to apply tui-tree's style.

```html
<div id="tree" class="tui-tree-wrap"></div>
```

### JavaScript

This can be used by creating an instance with the constructor function.
To get the constructor function, you should import the module using one of the following ways depending on your environment.

#### Using namespace in browser environment

```javascript
const Tree = tui.Tree;
```

#### Using module format in node environment

```javascript
const Tree = require('tui-tree'); /* CommonJS */
```

```javascript
import Tree from 'tui-tree'; /* ES6 */
```

You can create an instance with [options](https://nhn.github.io/tui.tree/latest/Tree) and call various APIs after creating an instance.

```javascript
const container = document.getElementById('tree');
const instance = new Tree(container, { ... });

instance.add( ... );
```

For more information about the API, please see [here](https://nhn.github.io/tui.tree/latest/Tree).
