install
# use npm
$ npm install rc-pure-component
# or yarn
$ yarn add rc-pure-component
usage
before
const Component = ({ name = 'Hieu' }) => (<div>hello, {name}</div>)
after
import pure from 'rc-pure-component'
// normal
const Component = pure(({ name = 'Hieu' }) => (<div>hello, {name}</div>))
// custom
const shallowCompare = (prevProps, nextProps) => !(prevProps === nextProps)
const Component = pure(({ name = 'Hieu' }) => (<div>hello, {name}</div>), shallowCompare)
compare
by default I use the calculation of fb, here:
import shallowEqual from 'fbjs/lib/shallowEqual'
const shallowCompare = (prevProps, nextProps) => !shallowEqual(prevProps, nextProps)
alternatively, you can use the function of the lodash:
import isEqual from 'lodash/isEqual'
const shallowCompare = (prevProps, nextProps) => !isEqual(prevProps, nextProps)
