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:
```html
```
```ts
// npm install --save sakana-widget
import 'sakana-widget/lib/index.css';
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:
```ts
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:
```ts
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:
```ts
const github = SakanaWidget.getCharacter('chisato');
github.image = `https://raw.githubusercontent.com/dsrkafuu/sakana-widget/main/docs/github.png`;
SakanaWidget.registerCharacter('github', github);
new SakanaWidget({ character: 'github' }).mount('#sakana-widget');
```
See the [API](#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](https://developer.mozilla.org/docs/Web/Guide/CSS/Block_formatting_context)**, 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.
