Add the Sakana! Widget to your own web page! Support custom images, auto resizing and more runtime params!

Features

• Register and use your own character
• Auto resizing support, 120px minimum
• Press and hold the stand and drag, after releasing the hand the stand will bounce in the opposite direction
• Use control bar to switch roles and use other functions
• Automatic mode, applying a force of random size at random intervals
• Prepared for CDN/NPM import, custom parameters, chained calls

Usage

First you need to import the module, either directly using a CDN or by installing it as an NPM package:

<!-- https://cdn.jsdelivr.net/npm/[email protected]/lib/sakana.min.js -->
<!-- https://cdnjs.cloudflare.com/ajax/libs/sakana-widget/2.3.2/sakana.min.js -->
<div id="sakana-widget"></div>
<script>
  function initSakanaWidget() {
    new SakanaWidget().mount('#sakana-widget');
  }
</script>
<script
  async
  onload="initSakanaWidget()"
  src="https://cdn.jsdelivr.net/npm/[email protected]/lib/sakana.min.js"
></script>

// npm install --save sakana-widget
import SakanaWidget from 'sakana-widget';
new SakanaWidget().mount('#sakana-widget');

This package exports a class SakanaWidget by default, through which a widget can be initialized. The code above initializes a widget with default settings and mounts it to the #sakana-widget element.

You can continue to create widget instances and mount to more DOM elements, where the data is completely independent between widgets except for roles, and non-static methods support chaining calls.

For example, you can modify some settings before mounting a widget and get a super-slow Chisato:

new SakanaWidget().setState({ i: 0.001, d: 1 }).mount('#sakana-widget');

Or, get the built-in character object via the getCharacter static method, modify the parameters, and create a super-slow, non-damped (perpetual) Takina as a new character:

const takina = SakanaWidget.getCharacter('takina');
takina.initialState = {
  ...takina.initialState,
  i: 0.001,
  d: 1,
};
SakanaWidget.registerCharacter('takina-slow', takina);
new SakanaWidget({ character: 'takina-slow' }).mount('#sakana-widget');

Of course, you can use your own image (url or base64) as a character, e.g. GitHub's icon:

const github = SakanaWidget.getCharacter('chisato');
github.image = `https://raw.githubusercontent.com/dsrkafuu/sakana-widget/main/public/github.png`;
SakanaWidget.registerCharacter('github', github);
new SakanaWidget({ character: 'github' }).mount('#sakana-widget');

See the API section below for detailed parameters and class type.

Auto Resizing

Set autoFit: true when initializing the component and it will automatically scale according to the size of its mount container, minimum 120px.

Note that to turn on auto-scaling you need to make sure the mounting container is a BFC, the easiest way to do this is to set position: relative or position: fixed. Components in auto-scaling mode additionally add a wrapper container between the app and the mount container, and set its width and height to 100% by which the actual size is detected, so the BFC is required.
