React/Redux/Backend set-up to get realtime incremental progress
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}
Let's say I have React/Redux frontend that submits a form.
On receiving the form, my backend portion will then execute a script on ten files sequentially. I want to show the incremental progress on the frontend as this happens (i.e. Number of files completed currently).
The OP of this question set up a reducer that updates the state as a number. How would we integrate with the backend? Is it possible to do without using sockets?

The best way I think is to use websocket which the backend will publish the progress event and the frontend subscribe to that even. However, as you prefer not using websocket, the only way I can think of is to use interval polling.
Inside your redux action, you can do something like this:
async doSomething = () => {
return async (dispatch) => {
await callApiForStart(); // call your api to start the progressing
dispatch(startProgressing()); // tell the reducer to update the progressing
const interval = setInterval(async () => {
const result = await callApiToCheckProgress(); // in the backend, you can store the progress to somewhere like memory or redis or even DB.
dispatch(increaseProgress(result)); // tell the reducer to update the progress base on result
if (result === true) { // any condition to complete the check
clearInterval(interval);
dispatch(stopProgressing());
}
}, 1000); // my example interval is 1000, should depends on your logic
}
}
