How to loop over the redux state data after redux action has completed
I have a basic need about redux actions but I don't know how can i solve it.
This is my scenerio;
I have a redux action like as follows and I want to loop over the data after redux action has completed in my statefull component.
export const fetchServiceTypes = () => {
return dispatch => {
dispatch(fetchStStart());
axios.get(GAMMA_CONSTANTS.LINK_SERVICETYPES)
.then(res => {
dispatch(fetchStSuccess(res.data))
})
})
.catch(err => {
dispatch(fetchStFail(err))
})
}
}
In the component, I call the redux action in the componentWillMount function like as follows but I think, because redux action works asynchronously, i couldn't loop over the redux state as soon as it finished
componentWillMount() {
if (this.props.serviceTypes.length === 0)
this.props.onFetchServiceTypes();
this.props.serviceType.forEach(x => {
// TO DO
})
}
Anybody how to solve that?
Thank you

componentDidMount
is only triggered once before the component has rendered, and it doesn't care if your data is there or not. You could listen for a change in the state instead. This article explains how the new lifecycle method works.
Side note: If you are only looking to show the data you can actually loop over it directly in the html and it will be updated whenever the state is updated.
