Using asynchronous await on dispatch
Solution 1
That should work quite well (assuming you have redux-thunk
in your middleware). I use a similar approach (with promises rather than async
/await
) in several React/Redux apps.
There is a redux-promise
as well, but I find it insufficient for two reasons: there's no "begin" action, and there's no way to set meta
which is often necessary for asynchronous actions. So I prefer to dispatch the actions explicitly rather than the promises, as your code does.
Solution 2
I use this pattern :
const result = (res) => {
if (!res.result) {
this.setState({
...this.state,
Valid: false
});
}
};
AsyncFn(this.props.dispatch, field , result);
export async function AsyncFn(dispatch, field, Callback) {
try {
const response = await (
request.post(url)
);
if (response && response.body) {
if (response.body.result) {
dispatch(Auth());
dispatch(openModal());
} else {
Callback(response.body);
}
} else {
Callback({ result: false, message: 'Not valid' });
}
} catch (err) {
Callback({ result: false, message: err.message });
}
}

I was tinkering around with async await in react-native by making the dispatch asynchronous. Is there anything wrong or problematic with making the dispatch asynchronous as shown below? It seems to work (other than it's a polyfill). If there's nothing wrong with this approach, I'm thinking it could work quite nice for react-native.
export function fetchData(date, lng, lat){ const {year, month} = date; return async(dispatch) => { dispatch(requestData()) try { const data = await request(`http://data.police.uk/api/crimes-street/all-crime?lat=${lat}&lng=${lng}&date=${year}-${month}`) dispatch(recieveData(data)) } catch (err) { dispatch(requestError(err)) } } }
