The best way to access your store in a component is to use the connect()
function, that creates a new component that wraps around your existing one. This pattern is called Higher-Order Components, and is generally the preferred way of extending a component's functionality in React. This allows you to map state and action creators to your component, and have them passed in automatically as your store updates.
Let's take an example of <FilterLink>
component using connect:
import { connect } from 'react-redux'
import { setVisibilityFilter } from '../actions'
import Link from '../components/Link'
const mapStateToProps = (state, ownProps) => ({
active: ownProps.filter === state.visibilityFilter
})
const mapDispatchToProps = (dispatch, ownProps) => ({
onClick: () => dispatch(setVisibilityFilter(ownProps.filter))
})
const FilterLink = connect(
mapStateToProps,
mapDispatchToProps
)(Link)
export default FilterLink
Due to it having quite a few performance optimizations and generally being less likely to cause bugs, the Redux developers almost always recommend using connect()
over accessing the store directly (using context API).
class MyComponent {
someMethod() {
doSomethingWith(this.context.store)
}
}
