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",
"vf_video_teaser__title": "More on our YouTube channel",
"teasers": [
{
"vf_video_teaser__link": "A presentation on something to do with Life Sciences.",
"vf_video_teaser__poster": "https://acxngcvroo.cloudimg.io/v7/https://www.embl.org/files/wp-content/uploads/2020/04/SEMINARS_1102_lecture_vision2020_hd_retouched_500px.jpg",
"video_href": "JavaScript:Void(0);"
},
{
"vf_video_teaser__link": "Take a look at the fancy Helix building",
"vf_video_teaser__poster": "https://acxngcvroo.cloudimg.io/v7/https://www.embl.org/files/wp-content/uploads/2020/04/CONFERENCES_NonCodingSymp_7804_Retouched_500px.jpg",
"video_href": "JavaScript:Void(0);"
}
]
}
%}
{% include "../path_to/vf-video-teaser/vf-video-teaser.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-teaser', {
"component-type": "block",
"vf_video_teaser__title": "More on our YouTube channel",
"teasers": [
{
"vf_video_teaser__link": "A presentation on something to do with Life Sciences.",
"vf_video_teaser__poster": "https://acxngcvroo.cloudimg.io/v7/https://www.embl.org/files/wp-content/uploads/2020/04/SEMINARS_1102_lecture_vision2020_hd_retouched_500px.jpg",
"video_href": "JavaScript:Void(0);"
},
{
"vf_video_teaser__link": "Take a look at the fancy Helix building",
