Video Teaser block

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": "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",
      "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);"
    }
  ]
} %}
