# How to integrate ReX in your project
## A) JavaScript modules

### <img src="https://raw.githubusercontent.com/rakuten-rex/radio-button/master/project-scripts/webpack/markdown/logos/react.svg?sanitize=true" height="16" /> React component (JavaScript + CSS Styles)

For plug and play components integration.   

Example: 

`my-component.jsx`

```jsx
import RadioGroup from '@rakuten-rex/radio-button/RadioGroup';

function MyCustomComponent() {
  return (
    <RadioGroup options={[{ "id" : "fastestAnimal1" , "name" : "fastest" , "value" : "BrownHare" , "label" : "BrownHare" , "checked" : false, "disabled" : false, "required" : false }, { "id" : "fastestAnimal2" , "name" : "fastest" , "value" : "Wildebeest" , "label" : "Wildebeest" , "checked" : false, "disabled" : false, "required" : false }, { "id" : "fastestAnimal3" , "name" : "fastest" , "value" : "Cheetah" , "label" : "Cheetah" , "checked" : false, "disabled" : false, "required" : false }, { "id" : "fastestAnimal4" , "name" : "fastest" , "value" : "Pronghorn" , "label" : "Pronghorn" , "checked" : false, "disabled" : false }]} />
  );
}
```

### <img src="https://raw.githubusercontent.com/rakuten-rex/radio-button/master/project-scripts/webpack/markdown/logos/css-3.svg?sanitize=true" height="16" /> CSS Styles only

For your own JavaScript integration (React, Vue, Angular, etc.) or Static HTML.

#### Using CSS Variables (Modern Websites and WebApps)

Example: 

`my-component.jsx`

```jsx
import '@rakuten-rex/radio-button/RadioGroup/css';

function MyCustomComponent() {
  return (
    <div class="rex-radio-group" role="radiogroup">
      <div class="rex-radio"><input type="radio" value="BrownHare" id="fastestAnimal1" name="fastest" /><label class="rex-radio-label" for="fastestAnimal1">BrownHare</label></div>
      <div class="rex-radio"><input type="radio" value="Wildebeest" id="fastestAnimal2" name="fastest" /><label class="rex-radio-label" for="fastestAnimal2">Wildebeest</label></div>
      <div class="rex-radio"><input type="radio" value="Cheetah" id="fastestAnimal3" name="fastest" /><label class="rex-radio-label" for="fastestAnimal3">Cheetah</label></div>
      <div class="rex-radio"><input type="radio" value="Pronghorn" id="fastestAnimal4" name="fastest" /><label class="rex-radio-label" for="fastestAnimal4">Pronghorn</label></div>
    </div>
  );
}
```

#### Using Static CSS (Legacy Websites)

Example: 

`my-component.jsx`

```jsx
import '@rakuten-rex/radio-button/RadioGroup/css/static';

function MyCustomComponent() {
  return (
    <div class="rex-radio-group" role="radiogroup">
      <div class="rex-radio"><input type="radio" value="BrownHare" id="fastestAnimal1" name="fastest" /><label class="rex-radio-label" for="fastestAnimal1">BrownHare</label></div>
      <div class="rex-radio"><input type="radio" value="Wildebeest" id="fastestAnimal2" name="fastest" /><label class="rex-radio-label" for="fastestAnimal2">Wildebeest</label></div>
      <div class="rex-radio"><input type="radio" value="Cheetah" id="fastestAnimal3" name="fastest" /><label class="rex-radio-label" for="fastestAnimal3">Cheetah</label></div>
      <div class="rex-radio"><input type="radio" value="Pronghorn" id="fastestAnimal4" name="fastest" /><label class="rex-radio-label" for="fastestAnimal4">Pronghorn</label></div>
    </div>
  );
}
```

### <img src="https://raw.githubusercontent.com/rakuten-rex/radio-button/master/project-scripts/webpack/markdown/logos/sass.svg?sanitize=true" height="16" /> Sass mixins

For your own customization of styles (React, Vue, Angular, etc.) or Static HTML.

Example: 

`my-styles.scss`

```scss
@import '@rakuten-rex/radio-button/Radio/sass/styles.mixin';

.rex-radio {
  @include rex-radio();
}
```

### <img src="https://raw.githubusercontent.com/rakuten-rex/radio-button/master/project-scripts/webpack/markdown/logos/vue.svg?sanitize=true" height="16" /> Vue.js

A basic implementation based on HTML structure and import CSS styles into your component.

Example: 

`my-component.vue`

```vue
<template>
    <div class="rex-radio-group" role="radiogroup">
      <div class="rex-radio"><input type="radio" value="BrownHare" id="fastestAnimal1" name="fastest" /><label class="rex-radio-label" for="fastestAnimal1">BrownHare</label></div>
      <div class="rex-radio"><input type="radio" value="Wildebeest" id="fastestAnimal2" name="fastest" /><label class="rex-radio-label" for="fastestAnimal2">Wildebeest</label></div>
      <div class="rex-radio"><input type="radio" value="Cheetah" id="fastestAnimal3" name="fastest" /><label class="rex-radio-label" for="fastestAnimal3">Cheetah</label></div>
      <div class="rex-radio"><input type="radio" value="Pronghorn" id="fastestAnimal4" name="fastest" /><label class="rex-radio-label" for="fastestAnimal4">Pronghorn</label></div>
    </div>
</template>
<script>
export default {
  name: 'MyComponent',
}
</script>
<style scoped>
@import "~@rakuten-rex/radio-button/RadioGroup/css";
</style>
```


## B) Static HTML

Copy-paste the stylesheet `<link>` into your `<head>` tag to load our CSS styles.

### Using CSS Variables (Modern Websites and WebApps)
**Production mode URL** (recommended for Static HTML projects):  
```
https://unpkg.com/@rakuten-rex/radio-button@1.4.0/RadioGroup/RadioGroup.production.min.css
```


Development mode URL (for local testing):  

```
https://unpkg.com/@rakuten-rex/radio-button@1.4.0/RadioGroup/RadioGroup.development.css
```


### Using Static CSS (Legacy Websites)

```
https://unpkg.com/@rakuten-rex/radio-button@1.4.0/RadioGroup/RadioGroup.static.css
```

### <img src="https://raw.githubusercontent.com/rakuten-rex/radio-button/master/project-scripts/webpack/markdown/logos/html-5.svg?sanitize=true" height="16" /> Single component integration
Add it from unpkg.com CDN (NPM) into your HTML template or HTML static page.

Example: 

`my-page.html`

```html
<!doctype html>
<html>
  <head>
    <meta charset="utf-8">
    <title>My Page</title>
    <!-- ReX radio-button -->
    <link href="https://unpkg.com/@rakuten-rex/radio-button@1.4.0/RadioGroup/RadioGroup.production.min.css" rel="stylesheet">
  </head>
  <body>
    <div class="rex-radio-group" role="radiogroup">
      <div class="rex-radio"><input type="radio" value="BrownHare" id="fastestAnimal1" name="fastest" /><label class="rex-radio-label" for="fastestAnimal1">BrownHare</label></div>
      <div class="rex-radio"><input type="radio" value="Wildebeest" id="fastestAnimal2" name="fastest" /><label class="rex-radio-label" for="fastestAnimal2">Wildebeest</label></div>
      <div class="rex-radio"><input type="radio" value="Cheetah" id="fastestAnimal3" name="fastest" /><label class="rex-radio-label" for="fastestAnimal3">Cheetah</label></div>
      <div class="rex-radio"><input type="radio" value="Pronghorn" id="fastestAnimal4" name="fastest" /><label class="rex-radio-label" for="fastestAnimal4">Pronghorn</label></div>
    </div>
  </body>
</html>
```
