Chapter 6. Publish ActiveDocs in the Developer Portal

By the end of this tutorial, you will have published your ActiveDocs in your Developer Portal.

Once you have created an specification and you have added it to 3scale, it is time to publish the specification and link it on your Developer Portal to be used by your API developers.

Add the following snippet to the content of any page of your Developer Portal. This must be done through the CMS of your Developer Portal. Note that SERVICE_NAME should be the system name of the service specification, pet_store in the example. 

<h1>Documentation</h1>
<p>Use our live documentation to learn about Echo API</p>
{% active_docs version: "2.0" services: "SERVICE_NAME" %}
{% cdn_asset /swagger-ui/2.2.10/swagger-ui.js %} {% cdn_asset /swagger-ui/2.2.10/swagger-ui.css %} {% include 'shared/swagger_ui' %}
<script type="text/javascript">
  $(function () {
    {% comment %}
      // you have access to swaggerUi.options object to customize its behaviour
      // such as setting a different docExpansion mode
      window.swaggerUi.options['docExpansion'] = 'none';
      // or even getting the swagger specification loaded from a different url
      window.swaggerUi.options['url'] = "http://petstore.swagger.io/v2/swagger.json";
    {% endcomment %}
    window.swaggerUi.load();
  });
</script>

These are some additional considerations when publishing ActiveDocs in the Developer Portal:

  • You can specify only one service on one page. If you want to display multiple specifications, the best way is to do it on different pages.
  • This snippet requires jQuery, which is included by default in the main layout of your Developer Portal. If you remove the jQuery dependency from the main layout, you must add this dependency on the page containing ActiveDocs.
  • Make sure you have Liquid tags enabled on the CMS page.
  • The version used in the Liquid tag {{ '{% active_docs version: "2.0" ' }}%} should correspond to that of the Swagger spec.

If you want to fetch your specification from an external source, change the JavaScript code as follows: 

$(function () {
 window.swaggerUi.options['url'] = "SWAGGER_JSON_URL";
 window.swaggerUi.load();
});

Note that the line containing the source of the specification, window.swaggerUi.options['url'] = "SWAGGER_JSON_URL";, is outside of the comments block.
