# Script editor web part for modern pages built in React

This version works only for SharePoint Online. If you want a version for Sharepoint on-premises go to [react-script-editor-onprem](../react-script-editor-onprem).

## Summary
Coming from old classic SharePoint pages you might have existing script solutions you want to re-use on a modern page
without having to repackage it as a new SharePoint Framework web part. This web part is similar to the classic
Script Editor Web Part, and allows you do drop arbitrary script or html on a modern page.

> Notice. All client-side web parts are deployed or enabled to be available in site level by tenant administrator using tenant app catalog. If there are concerns on enabling script options in a tenant, this web part or a approach should not be approved by tenant administrators.

As an example add the following scripts to the web part in order to show stock ticker info on your page. First *tv.js* is loaded, and then the script block is executed to show the ticker information.

```html
<!-- TradingView Widget BEGIN -->
<div class="tradingview-widget-container">
  <div id="tradingview_e7aa0"></div>
  <div class="tradingview-widget-copyright"><a href="https://www.tradingview.com/symbols/NASDAQ-AAPL/" rel="noopener" target="_blank"><span class="blue-text">AAPL Chart</span></a> by TradingView</div>
  <script type="text/javascript" src="https://s3.tradingview.com/tv.js"></script>
  <script type="text/javascript">
  new TradingView.widget(
  {
  "width": 980,
  "height": 610,
  "symbol": "NASDAQ:AAPL",
  "interval": "D",
  "timezone": "Etc/UTC",
  "theme": "light",
  "style": "1",
  "locale": "en",
  "toolbar_bg": "#f1f3f6",
  "enable_publishing": false,
  "allow_symbol_change": true,
  "container_id": "tradingview_e7aa0"
}
  );
  </script>
</div>
<!-- TradingView Widget END -->
```

The web part works by loading each script in a `<script src>` tag sequentially in the order they are specified, then any other `<script>` block is executed.

If all you want is to add markup on the page, you can do that as well. Adding the following html would show a headline and a list.

```html
<h2>My header</h2>
<ul>
    <li>One
    <li>Two
    <li>Three
</ul>
```

You may add CSS via style tags or `link` tags.
```html
<!-- Latest compiled and minified CSS -->
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" integrity="sha384-BVYiiSIFeK1dGmJRAkycuHAHRg32OmUcww7on3RYdg4Va+PmSTsz/K68vbdEjh4u" crossorigin="anonymous">
<style>
    #container h1 {
        color: red;
    }
</style>
<div id="container">
    <h1>Headline</h1>
</div>
<div class="row">
    <div class="col-md-8">.col-md-8</div>
    <div class="col-md-4">.col-md-4</div>
</div>
<div class="row">
    <div class="col-md-4">.col-md-4</div>
    <div class="col-md-4">.col-md-4</div>
    <div class="col-md-4">.col-md-4</div>
</div>
```

## Support for Office UI Fabric styles
By adding the class name `ms-Fabric` to your top element, you can use use fabric CSS classes directly in the web part. See [Fabric Core](https://developer.microsoft.com/en-us/fabric#/get-started/web#fabric-core) for more information on Fabric classes.

**Sample**
```html
<div class="ms-Fabric">
    <span class="ms-font-su ms-fontColor-themePrimary">
        Big text in primary theme color
    </span>
</div>
```

## Support for classic _spPageContextInfo
If your scripts rely on the classic _spPageContextInfo, you can enable that in the web part property pane.

## Support for Teams tabs
If you want to use the solution as a Teams tab, perform the changes to deploy to [non-script](#deploy-to-non-script-sites--modern-team-sites) sites and [tenant wide deployment](#deploy-tenant-wide).

Next see the [Teams tab tutorial](https://docs.microsoft.com/en-us/sharepoint/dev/spfx/web-parts/get-started/using-web-part-as-ms-teams-tab) for steps needed to deploy the solution as a Teams tab.

You can get access to the Teams context information via the global variable `_teamsContexInfo`. The available properties are documented at [Teams context interface](https://docs.microsoft.com/en-us/javascript/api/@microsoft/teams-js/microsoftteams.context?view=msteams-client-js-latest).

**Sample**
```html
<div class="ms-Fabric">
    <span id="ScriptIt" class="ms-font-xxl ms-fontColor-neutralPrimary">
    </span>
</div>
<script>
var element = document.getElementById("ScriptIt");
element.innerHTML = "Team: " + _teamsContexInfo.teamName + "<br\>Channel: " + _teamsContexInfo.channelName;
</script>

```

## Minimal Path to Awesome
### Local testing

- Clone this repository
- In the command line run:
  - `npm install`
  - `gulp serve`

### Deploy
* gulp clean
* gulp bundle --ship
* gulp package-solution --ship
* Upload .sppkg file from sharepoint\solution to your tenant App Catalog
	* E.g.: https://&lt;tenant&gt;.sharepoint.com/sites/AppCatalog/AppCatalog
* Add the web part to a site collection, and test it on a page

### Deploy to non-script sites / modern team sites
By default this web part is not allowed on no-script sites, as it allows execution of arbitrary script. This is by design as from a security and governance perspective you might not want arbitrary script added to your pages. This is typically something you want control over.

If you however want to allow the web part for non-script sites like Office 365 Group modern team sites you have to edit `ScriptEditorWebPart.manifest.json` with the following change:
```
"requiresCustomScript": false
```

### Deploy tenant wide
By default you have to install this web part per site collection where you want it availble. If you want it enabled by default on all sites you have to edit `package-solution.json` with the following change:
```
"skipFeatureDeployment": true
```

In order to make it available to absolutely all sites you need apply the _Deploy to non-script sites / modern team site_ change as well.

## Features
This web part illustrates the following concepts on top of the SharePoint Framework:

- Re-use existing JavaScript solutions on a modern page
- Office UI Fabric
- React
