README
**react-var-ui** is a simple React component library for variable setting and preview, inspired by iOS settings, [react-dat-gui](https://github.com/claus/react-dat-gui) and [dat.gui](https://github.com/dataarts/dat.gui).
While some code from react-dat-gui was used, this library functions in a completely different way. The codebase uses modern React code practices such as hooks and functional components. Instead of iterating over the children array, react-var-ui uses a Context. Creation of custom components is also easier.
What makes react-var-ui different when compared to similar libraries such as [Leva](https://github.com/pmndrs/leva) or [react-dat-gui](https://github.com/claus/react-dat-gui), react-var-ui doesn't force itself to float over all your content, instead react-var-ui lives peacefully inside of the React node it is placed in. Unlike Leva and much more like react-dat-gui, react-var-ui relies on a local state variable, providing the developer with more flexibility. While this might seem less convenient, it allows for more customization and usage of multiple instances of react-dat-gui within one project.

## Installation
Install `react-var-ui` with either npm or yarn:
```
yarn add react-var-ui
# or
npm install react-var-ui
```
Then include the CSS with:
```css
/* In your CSS/SCSS file: */
@import 'react-var-ui/index.css';
```
or:
```js
// In your JS/TS file (assuming your bundler supports loading CSS files):
import 'react-var-ui/index.css';
```
## Example usage
```jsx
const [values, setValues] = React.useState({
toggle: true,
color: '#FF0000',
select: 1,
slider: 0.4,
xy: [0, 0.2],
string: 'Hello world!',
});
return (
alert('clicked!')} />
);
```
## Testing
react-var-ui uses jest for automated unit tests and storybook for manually testing the UI.
You can run unit tests after installing by running:
yarn test
Storybook can be ran with:
yarn storybook
To run the example app, you first need to start the project with:
yarn start
And then enter the example directory and start the app:
cd ./example
yarn start
(make sure to run `yarn install` before.)

## Custom input components
react-var-ui provides a `` component and a `useVarUIValue` hook designed to facilitate creation of custom components.
### Example usage
```tsx
import React from 'react';
import { useVarUIValue, IVarBaseInputProps, VarBase } from 'react-var-ui';
// Please specify the .
export interface IVarCustomProps extends IVarBaseInputProps {}
/**
* Custom input component. In this example, it's a simple text input.
*/
export const VarCustom = ({
label,
path,
value,
onChange,
disabled,
className,
}: IVarCustomProps): JSX.Element => {
/**
* currentValue will contain the current value from the value object
* (at a given path) or value from properties if that's not available.
*
* setCurrentValue will set the value onto a given path in the object
* and call onChange if available.
*
* All arguments are optional, path/object-based value changes take
* precedence.
*/
const [currentValue, setCurrentValue] = useVarUIValue(path, value, onChange);
/**
* We're wrapping our component in VarBase which provides the default
* label.
*
* It is necessary to wrap what should appear on the right in a .
* If this behavior is undesired, a with grid-column: 1 / 3; can
* be used.
*/
return (
setCurrentValue(e.target.value)}
/>
);
};
