bem-components-react

A factory to create react components that follow BEM methodology with first-class typescript support.

Getting started

Installation:

  yarn add bem-components-react

  npm install --save bem-components-react

Usage:

import { bem } from 'bem-components-react'

// specify a class name and a list of variants afterwards
const Button = bem.button('button', ['large', 'small']) 

function MyComponent() {
  return <Button large>Click me</Button>
}

This component will render to:

<button class="button button--large">Click me</button>

API

// omit the second argument if the component doesn't have any modifiers
const Button = bem.button('button')

// specify an array of variants as a second argument
const Button = bem.button('button', ['large', 'small']) 

// nest elements inside blocks by specifying it in the name
const Input = bem.button('dialog__input', ['error'])

// to enable a variant, pass a prop to the created component
<Button large>Click me</Button>

// you can pass any other prop to the created component
<Input error placeholder="write here"/>

// you can pass extra classNames to the component
<Button large className="foo">Click me</Button>
// will result in
<button classname="button button--large foo">Click me</button>

Using a custom prefix for classes

import { withPrefix } from 'bem-components-react'
const bem = withPrefix('myapp')

const Button = bem.button('button', ['large', 'small']) 

Will render to:

<button class="myapp-button myapp-button--large">Click me</button>
