Available configuration

Embed Tool supports some services by default (see the full list here). You can specify services you would like to use:

`javascript
var editor = CodexEditor({
...

tools: {
...
embed: {
class: Embed,
config: {
services: {
youtube: true,
coub: true
}
}
},
},

...
});
`

> Note that if you pass services you want to use like in the example above, others will not be enabled.

Also you can provide your own services using simple configuration.


First of all you should create a Service configuration object. It contains following fields:

| Field | Type | Description |
| ---------- | ---------- | ----------- |
| regex | RegExp | Pattern of pasted URLs. You should use regexp groups to extract resource id
| embedUrl | string | Url of resource\s embed page. Use <%= remote_id %> to substitute resource identifier
| html | string | HTML code of iframe with embedded content. embedUrl will be set as iframe src
| height | number | _Optional_. Height of inserted iframe
| width | number | _Optional_. Width of inserted iframe
| id | Function | _Optional_. If your id is complex you can provide function to make the id from extraced regexp groups

Example:

``javascript
{
regex: /https?:\/\/codepen.io\/([^\/\?\&])\/pen\/([^\/\?\&])/,
embedUrl: 'https://codepen.io/<%= remote_id %>?height=300&theme-id=0&default-tab=css,result&embed-version=2',
html: "",
height: 300,
width: 600,
id: (groups) => groups.join('/embed/')
}
`

When you create a Service configuration object, you can provide it with Tool\s configuration:

``javascript
var editor = CodexEditor({
...

tools: {
...
embed: {
class: Embed,
config: {
services: {
youtube: true,
coub: true,
codepen: {
regex: /https?:\/\/codepen.io\/([^\/\?\&])\/pen\/([^\/\?\&])/,
embedUrl: 'https://codepen.io/<%= remote_id %>?height=300&theme-id=0&default-tab=css,result&embed-version=2',
html: "",
height: 300,
width: 600,
id: (groups) => groups.join('/embed/')
}
}
}
},
},

...
});
`

#### Inline Toolbar
CodeX Editor provides useful inline toolbar. You can allow it\s usage in the Embed Tool caption by providing inlineToolbar: true.

``javascript
var editor = CodexEditor({
...

tools: {
...
embed: {
class: Embed,
inlineToolbar: true
},
},

...
});
`

| Field | Type | Description

| service | string | service unique name
| source | string | source URL
| embed | string | URL for source embed page
| width | number | embedded content width
| height | number | embedded content height
