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" : "embl-element",
"logo_text" : "European Molecular Biology Laboratory Home",
"logo_href" : "/",
 }
%}
{% include "../path_to/embl-logo/embl-logo.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 '@embl-logo', {
  "component-type" : "embl-element",
  "logo_text" : "European Molecular Biology Laboratory Home",
  "logo_href" : "/",}
%}
                

<a href="/" class="embl-logo">
  <span class="vf-u-sr-only" for="text">European Molecular Biology Laboratory Home</span>
</a>
