Nunjucks syntax
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 (exampe), 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": "block",
"global_logo": {
"logo_href": "/",
"image": "../../assets/vf-logo/assets/logo.svg",
"logo_text": "Visual Framework for Life Science websites"
}
}
%}
{% include "../path_to/vf-global-header/vf-global-header.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-global-header', {
"component-type": "block",
"global_logo": {
"logo_href": "/",
"image": "../../assets/vf-logo/assets/logo.svg",
"logo_text": "Visual Framework for Life Science websites"
}
} %}
