## CSS Modules: local scope & modular
[`CSS Modules`](https://github.com/css-modules/css-modules) assigns a local class a global unique name, so a component styles will not affect other components. e.g.
```css
/* button.css */
.button {
font-size: 16px;
}
.mini {
font-size: 12px;
}
```
It's will transformed to something similar to:
```css
/* button.css */
.button__button--d8fj3 {
font-size: 16px;
}
.button__mini--f90jc {
font-size: 12px;
}
```
When importing the CSS Module from a JS Module, it exports an object with all mappings from local names to global names. Just like this:
```javascript
import styles from './button.css'
// styles = {
// button: 'button__button--d8fj3',
// mini: 'button__mini--f90jc'
// }
element.innerHTML = ''
```
## `vue-css-modules`: simplify mapping name
Here's a button component with CSS Modules:
```html
Click me
import styles from './button.css'
export default {
props: { mini: Boolean },
data: () => ({ styles })
}
```
Surely, CSS Modules is a good choice for Vue components. But here are a few disadvantages:
- You have to pass `styles` object into `data` function.
- You have to use `styles.localClassName` importing a global class name.
- If there are other global class names, you have to put them together.
- If you want to bind a class name to a component property value, you have to explicitly specify the property name, even if the class name is equals the property name.
Now, you can use `vue-css-modules` to remake it:
```html
Click me
import CSSModules from 'vue-css-modules'
import styles from './button.css'
export default {
mixins: [CSSModules(styles)],
props: { mini: Boolean }
}
```
Using `vue-css-modules`:
- You don't need pass `styles` object into `data` function, but the `CSSModules` mixin. π
- You can completely say byebye to `styles.localClassName`.
- There is clear distinction between global CSS and CSS Modules.
- You can use the `:` modifier to bind the property with the same name.
## Modifiers
### @button
```html
Button
```
This is the equivalent to:
```html
Button
```
This allows you to override component styles in context:
```css
.form [data-component-button] {
font-size: 20px;
}
```
### $type
```html
Button
```
This is the equivalent to:
```html
Button
```
### :mini
```html
Button
```
This is the equivalent to:
```html
Button
```
### disabled=isDisabled
```html
Button
```
This is the equivalent to:
```html
Button
```
## Usage
### In templates
#### CSS Modules outside the template
```html
Click me
import CSSModules from 'vue-css-modules'
import styles from './button.css'
export default {
mixins: [CSSModules(styles)],
props: { mini: Boolean }
}
```
#### CSS Modules inside the template
```html
Click me
import CSSModules from 'vue-css-modules'
export default {
mixins: [CSSModules()],
props: { mini: Boolean }
}
.button {
font-size: 16px;
}
.mini {
font-size: 12px;
}
```
### In JSX
```javascript
import CSSModules from 'vue-css-modules'
import styles from './button.css'
export default {
mixins: [CSSModules(styles)],
props: { mini: Boolean },
render() {
return (
Click me
)
}
}
```
### In render functions
```javascript
import CSSModules from 'vue-css-modules'
import styles from './button.css'
export default {
mixins: [CSSModules(styles)],
props: { mini: Boolean },
render(h) {
return h('button', {
styleName: '@button :mini'
}, 'Click me')
}
}
```
## The implementation
`vue-css-modules` extends `$createElement` method of the current component. It will use the value of `styleName` in `data` or `data.attrs` to look for CSS Modules in the associated styles object and will append the matching unique CSS class names to the `data.staticClass` value.
