v1.2.0

Added

• Added new rule no-property-visibility-mismatch. This rule will ensure public properties use @property and non-public properties use @internalProperty (#100)
• Added new rule no-missing-element-type-definition This rule will ensure that custom elements are registered on the
  HTMLElementTagNameMap Typescript interface (#73)
• It's now possible to configure how many modules deep dependencies are followed to determine whether a custom element is available in the current file. When -1 is used, dependencies will be followed infinitely deep. This can be configured for both external dependencies and project dependencies with maxNodeModuleImportDepth & maxProjectImportDepth (#116)
• In addition to extending HTMLElementTagNameMap it's now also possible extend the HTMLElementEventMap interface and the HTMLElement interface (#53)

Example:

declare global {
  interface HTMLElementTagNameMap {
    "my-element": HTMLElement;
  }
  interface HTMLElementEventMap {
    "my-event": Event;
  }
}

/**
 * @attr my-attr
 */
interface HTMLElement {
  myProperty: string;
}

• The role and controlslist attributes are now correctly type checked (#89)
• Added autocompletion for CSS shadow parts and CSS custom properties in CSS. It's possible to document those using JSDoc (dd1ffc78)

Example:

/**
 * @cssprop {Color} --border-color - Sets the color of the border
 * @csspart content - The content of my element
 */
class MyElement extends HTMLElement {
}

Fixed and changed
