In this project, I used eventChannel in redux-saga module.
function subscriber(alphabet_index) {
return eventChannel(emitter => {
const iv = setInterval(async () => {
/**
* data includes { countries, alphabetIdx }
*/
let data = await getAlphabetCounteries(alphabet_index ++);
emitter(data)
}, 15000);
// The subscriber must return an unsubscribe function
return () => {
clearInterval(iv)
}
}
)
}
function* saga() {
const chan = yield call(subscriber, 0)
try {
while(true) {
let data = yield take(chan)
yield put(PUT_COUNTRIES(data));
}
} finally {
console.log("terminated");
}
}I get country data from https://restcountries.eu/.
return axios.get("https://restcountries.eu/rest/v2/all").then((response) => {
...
});
