## Minimal Path to Awesome
- clone this repo
- `$ npm i`
- `$ gulp trust-dev-cert`
- `$ gulp serve `

#### Local Mode
A browser in local mode (localhost) will be opened.
https://localhost:4321/temp/workbench.html

#### SharePoint Mode
If you want to try on a real environment, open:
https://your-domain.sharepoint.com/_layouts/15/workbench.aspx

## Usage
Go to src/webparts/taxonomyPickerSample/TaxonomyPickerSampleWebPart.ts and configure the control.
#### Mock Data configuration by using defaultOptions configuration
Access from https://localhost:4321/temp/workbench.html
Configuration:
```js
PropertyPaneTaxonomyPicker("Language", {
  key: "Language_Field",
  name: "Language",
  displayName: "Language",
  multi: true,
  defaultOptions: [
    { label: "English", value: "f50249b6-310d-43b6-aaa6-f0cb46d851bf" },
    { label: "Spanish", value: "237ca323-1ed8-4199-a49b-a9f7ce4256bf" },
    { label: "German", value: "44024c7e-f738-4755-90e1-15866327c806" },
    { label: "Italian", value: "65f67491-bdca-491a-84fa-f6fd913f40fa" },
  ],
  onPickerChange: this._updateTaxonomyPicker
})
```
#### Real Data configuration by using termSetGuid configuration
Access from https://your-domain.sharepoint.com/_layouts/15/workbench.aspx
Configuration:
```js
PropertyPaneTaxonomyPicker("Language", {
  key: "Language_Field",
  name: "Language",
  displayName: "Language",
  multi: true,
  termSetGuid: "<your-term-set-id>",
  termSetName: "Language",
  termSetCountMaxSwapToAsync: 100,
  onPickerChange: this._updateTaxonomyPicker
})
```

## Features
- Use [React](https://facebook.github.io/react) for using [react-taxonomypicker](https://github.com/jquintozamora/react-taxonomypicker) control inside a custom property pane (it can be used in the webpart itself too).
- Use [TypeScript](https://www.typescriptlang.org) to create the custom property pane control containing the taxonomy picker control.
- **Reacting to web part property changes**
- Loading data for use in **custom property pane controls asynchronously** without blocking the web part
- **Retrieve Terms** from a Term Set by Term Set GUID.
- **Sync / Async modes**
  - Sync mode is used for medium / small Term Sets and loads **asynchronously** all Terms and store them in React State and SessionStorage cache.
  - Async mode is used for large Term Sets and it **doesn't load any data initially**, but it loads the Terms upon user input in batches of 10 items.
  - Sync / Async mode configurable via **termSetCountMaxSwapToAsync** property
    - The control will fetch the number of terms and decide which mode to use depends on termSetCountMaxSwapToAsync value.
- It Uses and depends on **SP.Taxonomy.js** (the webpart uses a wrapper to load all the SP.*.js dependencies)
- Use **Promise** (polyfill it if needed IE)
- **onPickerChange** event handler exposed
- [react-select](https://github.com/JedWatson/react-select) properties exposed (extends them)
- defaultOptions array exposed to enable input **mock data** when no termSetGuid configured
- More configuration options: [react-taxonomypicker](https://www.npmjs.com/package/react-taxonomypicker)

## Scenarios supported
- SharePoint Web Part using **Script Editor** or **Content Editor Web Part**
  - Consume it from [ES6 project](https://github.com/jquintozamora/react-taxonomypicker-consume-es6)
  - Consume it from [TypeScript project](https://github.com/jquintozamora/react-taxonomypicker-consume-typescript)
- **SharePoint Framework Web Part (SPFx)**
