  "nunjucks": {
    "paths": {
      "filters": "workspace/filters"

Filters are individual JavaScript files within the specifed directory:

  return input.toUpperCase()
}

 Usage: {{ renderProduct product }}
#}

{% macro renderProduct(product) %}
  helper: {{ product.name }} - £{{ product.price }}
{% endmacro %}
