Real presentation sample

Getting started

Talkie.js contains two of the CSS and one of JavaScript.

  • dist/talkie.min.css
  • dist/talkie.min.js
  • dist/talkie-default.min.css

Next code is the simplest example.

<html>
<head>
  <link rel="stylesheet" href="./dist/talkie.min.css">
  <link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/highlight.js/8.9.1/styles/monokai_sublime.min.css">
</head>
<body>

<!-- Pure HTML style -->
<section layout>
  <h1>Slide 1</h1>
</section>

<!-- Markdown style ( require `type` attribute ) -->
<script layout type="text/x-markdown">
# Slide 2
</script>

<!-- You can also use `<template>` element -->
<template layout type="text/x-markdown">
# Slide 2
</template>

<script src="//cdnjs.cloudflare.com/ajax/libs/highlight.js/8.9.1/highlight.min.js"></script>
<script src="./dist/talkie.js"></script>
<script>Talkie();</script>
</body>
</html>

If you use the code highlighting, you must load these files.

<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/highlight.js/8.9.1/styles/monokai_sublime.min.css">
<script src="//cdnjs.cloudflare.com/ajax/libs/highlight.js/8.9.1/highlight.min.js"></script>

Slide ratio

The default slide 4:3 (width 1024px, height 768px). In the following code ratio 16:9 (width: 1366px, height 768px) you will.

Talkie({wide: true});

Backface image & filter

You can add backface attribute into each slides. Image path that you specify in the backface attribute will be the background of when the slide is displayed.

<section layout
         backface="background-image.jpg"
         backface-filter="blur(1px) brightness(.8)">

  <h1>Title</h1>
  <p>foo, bar, baz, qux...</p>

</section>

backface-filter attribute is applied to the background image as CSS Filters. But using this, will occur side effect significantly to performance on mobile device.

All options

interface TalkieOptions {
  wide?: boolean;
  control?: boolean;
  pointer?: boolean;
  progress?: boolean;
  backface?: boolean;
  notransition?: boolean;
}

Talkie(options);

FullScreen mode

When you press the "f" key will be a full-screen mode. "f" or "Esc" key Press and then exit.

Pointer mode

When you press the "b" key, the pointer visibility is toggled

Canvas drawing mode

When you press the "v" key, the drawing mode is toggled, and clear line when press "c" key.

Custom key binding & control

Talkie() returns an object with initialization. This object has some of the control bus and functionality.

var talkie  = Talkie({wide:false});

You can define any key bindings.

talkie.key('space').subscribe(talkie.next$);
talkie.key('s').subscribe(talkie.next$);
talkie.key('n').subscribe(talkie.next$);
talkie.key('a').subscribe(talkie.prev$);
talkie.key('p').subscribe(talkie.prev$);

It is also possible to control these functions in the program.

window.next = function() {
  talkie.next$.next();
};
window.prev = function() {
  talkie.prev$.next();
};
window.jump = function(num) {
  talkie.jump$.next(num);
};

All exports

interface TalkieExports {
  key: (charKey: string) => Observable<KeyboardEvent>;
  notes: { [pageNum: number]: string };
  changed: Observable<HTMLElement>;
  ratio: Observable<number>;
  next$: Subject<void>;
  prev$: Subject<void>;
  jump$: Subject<number>;
}

var exports = Talkie();
