Isolating components¤

By default, components behave similarly to Django's {% include %}, and the template inside the component has access to the variables defined in the outer template.

You can selectively isolate a component, using the only flag, so that the inner template can access only the data that was explicitly passed to it:

{% component "name" positional_arg keyword_arg=value ... only %}

component_css_dependencies¤

{% component_css_dependencies %}
-

See source code

Marks location where CSS link tags should be rendered after the whole HTML has been generated.

Generally, this should be inserted into the <head> tag of the HTML.

If the generated HTML does NOT contain any {% component_css_dependencies %} tags, CSS links are by default inserted into the <head> tag of the HTML. (See JS and CSS output locations)

Note that there should be only one {% component_css_dependencies %} for the whole HTML document. If you insert this tag multiple times, ALL CSS links will be duplicately inserted into ALL these places.

component_js_dependencies¤

{% component_js_dependencies %}
-

See source code

Marks location where JS link tags should be rendered after the whole HTML has been generated.

Generally, this should be inserted at the end of the <body> tag of the HTML.

If the generated HTML does NOT contain any {% component_js_dependencies %} tags, JS scripts are by default inserted at the end of the <body> tag of the HTML. (See JS and CSS output locations)

Note that there should be only one {% component_js_dependencies %} for the whole HTML document. If you insert this tag multiple times, ALL JS scripts will be duplicately inserted into ALL these places.

Use this tag to insert content into component's slots.

{% fill %} tag may be used only within a {% component %}..{% endcomponent %} block. Runtime checks should prohibit other usages.

Args:

  • name (str, required): Name of the slot to insert this content into. Use "default" for the default slot.
  • default (str, optional): This argument allows you to access the original content of the slot under the specified variable name. See Accessing original content of slots
  • data (str, optional): This argument allows you to access the data passed to the slot under the specified variable name. See Scoped slots

Generate HTML attributes (key="value"), combining data from multiple sources, whether its template variables or static text.

It is designed to easily merge HTML attributes passed from outside with the internal. See how to in Passing HTML attributes to components.

Args:

  • attrs (dict, optional): Optional dictionary that holds HTML attributes. On conflict, overrides values in the default dictionary.
  • default (str, optional): Optional dictionary that holds HTML attributes. On conflict, is overriden with values in the attrs dictionary.
  • Any extra kwargs will be appended to the corresponding keys

The attributes in attrs and defaults are merged and resulting dict is rendered as HTML attributes (key="value").

Extra kwargs (key=value) are concatenated to existing keys. So if we have

provide¤

The "provider" part of the provide / inject feature. Pass kwargs to this tag to define the provider's data. Any components defined within the {% provide %}..{% endprovide %} tags will be able to access this data with Component.inject().

This is similar to React's ContextProvider, or Vue's provide().

Args:

  • name (str, required): Provider name. This is the name you will then use in Component.inject().
  • **kwargs: Any extra kwargs will be passed as the provided data.
