/**
|
|
A plugin outlet is an extension point for templates where other templates can
|
|
be inserted by plugins.
|
|
|
|
If you handlebars template has:
|
|
|
|
```handlebars
|
|
{{plugin-outlet "evil-trout"}}
|
|
```
|
|
|
|
Then any handlebars files you create in the `connectors/evil-trout` directory
|
|
will automatically be appended. For example:
|
|
|
|
plugins/hello/assets/javascripts/discourse/templates/connectors/evil-trout/hello.handlebars
|
|
|
|
With the contents:
|
|
|
|
```handlebars
|
|
<b>Hello World</b>
|
|
```
|
|
|
|
Will insert <b>Hello World</b> at that point in the template.
|
|
|
|
Optionally you can also define a view class for the outlet as:
|
|
|
|
plugins/hello/assets/javascripts/discourse/views/connectors/evil-trout/hello.js.es6
|
|
|
|
And it will be wired up automatically.
