0.7.0

Global components

Components can be prefixed with the global keyword, this will add them to the DOM automatically and it's methods can be called the same way as a store or module.

It is useful for components that only need one instance in the application,
like modals and notifications:

global component AlertModal {
  state shown : Bool = false

  fun open : Promise(Never, Void) {
    next { shown = true }
  }

  fun close : Promise(Never, Void) {
    next { shown = flase }
  }

  style base {
    position: fixed;
    bottom: 0;
    right: 0;
    left: 0;
    top: 0;
  }

  fun render : Html {
    if (shown) {
      <div::base> 
        <p>
          Are you sure?
        </p>

        <button onClick={close}>
          Ok
        </button>
      </div>
    } else {
      <></>
    }
  }
}

/* Later on somewhere else */
AlertModal.open()

Statically compiled components / HTML

In this release the compiler will detect components and HTML fragments that are essentially static, meaning that subsequent renders would always result in the same virtual DOM structure.

These fragments and components will be cached so to speak, they will only rendered once and get reused after that.

To give you an example, the following component will only be rendered once and is reused after that:

component Icons.Checkmark {
  fun render : Html {
    <svg>
      /* The svg data */
    </svg>
  }
}

component Main {
  fun render : Html {
    <div>
      <Icons.Checkmark/>
      <Icons.Checkmark/>
    </div>
  }
}
