Copy the folder named content-manager inside your <project-root>/extensions folder

👍 Active content type as previewable

To enable content type to be previewable and see preview, or clone entry, you've to add option previewable to true in a configuration json file (*.settings.json):

{
  "pluginOptions": {
+    "preview-content": {
+      "previewable": true
+    }
  }
}

🚀 Run your project

After successful installation you've to build a fresh package that includes plugin UI. To archive that simply use:

# npm
npm run build && npm run develop

# yarn
yarn build && yarn develop

✏️ Usage

Go to Settings > Preview Content

Base url

Here you can configure the base url of your frontend. This is a seperate field because it will be different depending on whether your project is running locally (e.g. http://localhost:3000) oder in production (e.g. https://your-site.com).

Default preview url

This is the default preview url the plugin uses for when your content type doesn't have its own url defined. For the default preview url there are three parameters provided by this plugin:

Parameter	Description
:baseUrl	See section above for explanation
:contentType	The content type to query
:id	The id of content to query

For example in NextJS you can make use of serverless functions to make an URL like this:

:baseUrl/api/preview/:contentType/:id

With your base url being http://localhost:3000, for example.

And put the logic there to render content.

Custom preview url

You can also provide a custom url per content type in its *.settings.json. To do so, add this line to its options:

{
  "pluginOptions": {
    "preview-content": {
      "previewable": true,
+      "url": ":baseUrl/your-path/:contentType/:id?a-custom-param=true"
    }
  }
}

Here you can see how the base url comes in handy: You cannot change the model in production, but you can change the base url in the settings.

Adding data to the url

To tell the plugin to allow injection of an entry's data add the following to your model's *.settings.json:

{
  "pluginOptions": {
    "preview-content": {
      "previewable": true,
+      "url": ":baseUrl/your-path/:contentType/<%= slug %>?a-custom-param=<%= title %>",
+      "usesValuesInUrl": true
    }
  }
}

The plugin will now replace <%= slug %> and <%= title %> with the correct values. What you put in the brackets (<%= %>) has to be a name of the an attribute. The syntax used here is lodash's template syntax.
