You’ve seen that the setup for dispatching Redux actions in a React component follows a very similar process: define an action creator, wrap it in another function that looks like (…args) => dispatch(actionCreator(…args)), and pass that wrapper function as a prop to your component.īecause this is so common, connect supports an “object shorthand” form for the mapDispatchToProps argument: if you pass an object full of action creators instead of a function, connect will automatically call bindActionCreators for you internally. For example:įunction Counter (, dispatch ) ,Ĭopy Defining mapDispatchToProps As An Object If you don't specify the second argument to connect(), your component will receive dispatch by default. Approaches for Dispatching Default: dispatch as a Prop The mapDispatchToProps functions are normally referred to as mapDispatch for short, but the actual variable name used can be whatever you want.
connect can accept an argument called mapDispatchToProps, which lets you create functions that dispatch when called, and pass those functions as props to your component.By default, a connected component receives props.dispatch and can dispatch actions itself.React Redux gives you two ways to let components dispatch actions: With React Redux, your components never access the store directly - connect does it for you. This is the only way to trigger a state change. You call store.dispatch to dispatch an action. Connect: Dispatching Actions with mapDispatchToPropsĪs the second argument passed in to connect, mapDispatchToProps is used for dispatching actions to the store.ĭispatch is a function of the Redux store.
