Component

kiss.ui.Component(config)

The Component is the base class for all KissJS UI components.

KissJS Component derives from HTMLElement, and therefore inherits all native DOM operations.

Most UI frameworks are encapsulating DOM elements with classes. Instead of that, KissJS is directly attaching new properties and new methods to DOM elements.

Let's imagine a Panel component built with KissJS. Because a KissJS Component is a pure DOM element, you can get your Panel using native DOM operations. Then, once you have your panel, you can directly call its methods like this:

const myPanel = document.getElementById("my-panel")
myPanel.expand()
myPanel.setAnimation("shakeX")

This way, it avoids the overhead of encapsulation (= no additional layers to cross). It's also easier to keep the memory clean: when you destroy your DOM element, everything attached to it (states, events...) is flushed and can be garbage collected.

KissJS components are partly using the Custom Web Components API. They are "half" Custom Web Components in the sense they're not using shadow DOM.

They are recognizable and easy to lookup in the DOM because their tag name always starts with "a-", like: "a-field", "a-button", "a-panel", "a-menu", and so on...

The Component base class also does a few things for us:

  • id generation (all KissJS components must have ids)
  • automatically inserted at a specific location in the DOM, using the optional "target" property
  • keep the component config attached to the component, to be able to serialize it / save it / rebuild it later
  • automatically adds a base class depending on the component type (example: "a-field", "a-button", ...)
  • we can bind custom methods, using the "methods" config
  • we can bind W3C events, using the "events" config
  • we can "subscribe" the component to one ore more PubSub channels, using the "subscriptions" config
  • a "render" method is automatically attached to manage the component rendering lifecycle
  • a "load" method can be attached to manage the component's loading / re-loading (typically when the component generation relies on data)
  • we can bind the component to one or more data collections, using the "collections" config: it will automatically reload the component when one of the binded collections changes
  • a few helper methods are attached automatically (show, hide, toggle, animation, showLoading, hideLoading...)
  • we can hook custom behavior in the lifecycle by using private methods like: _afterConnected, _afterRender, _afterShow, _afterHide, _afterDisconnected

# render(targetopt, load)

Render an Element at a specified DOM location The rendering is optimized to render only the element that are detached from the DOM.

The render() method is chainable with other Component's methods. For example:

myElement.render().showAt(100, 100).setAnimation("shakeX")
Parameters:
Name Type Attributes Default Description
target * <optional>

optional DOM target insertion point
load boolean true

true (default) to execute the component's load method after DOM insertion
