Depending on your environment you'll want to use render or include. As a rule of thumb: server-side use include, precompiled browser use render. If you're using vf-eleventy you should use include.

Using include

You'll need to pass a context object from your code or Yaml file (example), as well as the path to the Nunjucks template. Nunjucks' include is an abstraction of render and provides some additional portability.

{% set context fromYourYamlFile %}
- or -
{% set context = { 
"component-type" : "container",
"section-title" : "Video",
 }
%}
{% include "../path_to/vf-video-container/vf-video-container.njk" %}
                

Using render

This approach is best for bare-bones Nunjucks environments, such as precompiled templates with the Nunjucks slim runtime where include is not be available.

{% render '@vf-video-container', {
  "component-type" : "container",
  "section-title" : "Video",}
%}
