## Summary

* Plugin name: `grapesjs-template-manager`
* Commands
    * `open-templates`
    * `get-uuidv4`
    * `take-screenshot`
    * `save-as-template`
    * `delete-template`
* Storages
    * `indexeddb`
    * `firestore`
    * `rest-api`

> This plugin uses the [`<foreignObject>`](https://developer.mozilla.org/en-US/docs/Web/SVG/Element/foreignObject) [SVG](https://developer.mozilla.org/en-US/docs/Web/SVG) element to simulate thumbnails which works well for projects which do not use any external stylesheets such as bootstrap. If your pages rely on external stylesheets you can store image thumbnails with your pages via the `take-screenshot` command which uses the [dom-to-image](https://github.com/tsayen/dom-to-image) library to generate thumbnails. You can also access this library through `editor.domtoimage`. External images may fail to render due to CORS restrictions.

## Options

| Option | Description | Default |
|-|-|-
| `dbName` | Database name | `gjs` |
| `objectStoreName` | Collection name | `templates` |
| `loadFirst` | Load first template in storage | `true` |
| `indexeddbVersion` | IndexedDB schema version | `4` |
| `onDelete` | On successful template deletion | `Function` |
| `onDeleteError` | On error template deletion | `Function` |
| `onScreenShotError` | On error capturing screenshot | `Function` |
| `quality` | Generated screenshot quality | `.01` |
| `mdlTitle` | Template modal title | `Template Manager` |
| `apiKey` | `Firebase` API key | `` |
| `authDomain` | `Firebase` Auth domain | `` |
| `projectId` | `Cloud Firestore` project ID | `` |
| `enableOffline` | Enable `Firestore` support for offline data persistence | `true` |
| `settings` | `Firestore` database settings | `{ timestampsInSnapshots: true }` |
| `uuidInPath` | Add uuid as path parameter on store for `rest-api`(useful for validation) | `true` |

* Setting `loadFirst` to `false` prevents overwritting the contents of the editor with the contents of the first template in storage.
* Only use options for `Firebase` when using `Cloud Firestore` storage.
* `dbName` and `indexeddbVersion` only apply to `indexddb` storage.
* `objectStoreName` acts as collection name for both `firestore` and ` indexeddb`.
* When `uuidInPath` is set to `false` the store request will be `http://endpoint/store/` instead of `http://endpoint/store/{uuid}`

## Local/IndexedDB

```js
window.editor = grapesjs.init({
  container: '#gjs',
  // ...
  storageManager:  {
    type: 'indexeddb'
  },
  plugins: ['grapesjs-template-manager'],
  pluginsOpts: {
    'grapesjs-template-manager': { /* Options */ }
  }
});
```

## Firestore

Configure firestore access rules for your app.
Add libraries to `head` of document:

```html
<!-- The core Firebase JS SDK is always required and must be listed first -->
<script src="https://www.gstatic.com/firebasejs/8.3.1/firebase-app.js"></script>
<!-- TODO: Add SDKs for Firebase products that you want to use
https://firebase.google.com/docs/web/setup#available-libraries -->
<script src="https://www.gstatic.com/firebasejs/8.3.1/firebase-firestore.js"></script>
```

Add credentials:

```js
window.editor = grapesjs.init({
  container: '#gjs',
  // ...
  storageManager:  {
    type: 'firestore'
  },
  plugins: ['grapesjs-template-manager'],
  pluginsOpts: {
    'grapesjs-template-manager': { 
      // Firebase API key
      apiKey: 'FIREBASE_API_KEY',
      // Firebase Auth domain
      authDomain: 'app-id-00a00.firebaseapp.com',
      // Cloud Firestore project ID

    }
  }
});
```
