Ng-enjoyhint NPM

Ng-EnjoyHint

EnjoyHint is a web-tool that provides the simplest way to create interactive tutorials and hints for your site or web-application. It can also be used to highlight and sign application elements.

Ng-EnjoyHint is an rewrite of EnjoyHint that removes jQuery and brings a native Angular experience.

Installation

npm install ng-enjoyhint

Usage

Inject the NgEnjoyHintService into your component.

private readonly enjoyHintService = inject(NgEnjoyHintService);

Call runTutorial() to run the tutorial.

await this.enjoyHintService.runTutorial(
  [
    {
      selector: ".my-element",
      event: "click",
      description: "Click on this element",
    },
    {
      selector: ".my-other-element",
      event: "click",
      description: "Now click over here",
    },
  ]
);

How it works

When running a tutorial, an overlay is added to the page. Four semi-transparent elements, one on each side of the target element, de-emphasize the rest of the page and block user input. A description is shown on the side of the target element. The user can complete the configured event (normally a click) on the target element to advance to the next step of the tutorial. When the last step is completed, the overlay is removed.
