Usage

When create a saga file

When you create a src/sagas/*.js, the below code is inserted automatically.

import { put, call,takeLatest } from 'redux-saga/effects';
import * as actions from '../actions';
import * as api from '../api';

export default [];

In:

In the saga file, type action name with camelcase such as searchPokemon and save it.

import { put, call,takeLatest } from 'redux-saga/effects';
import * as actions from '../actions';
import * as api from '../api';

searchPokemon

export default [];

It will be expanded like this.

Out:

import { put, call,takeLatest } from 'redux-saga/effects';
import * as actions from '../actions';
import * as api from '../api';

export function* handleSearchPokemon(action) {
  try {
    const { data } = yield call(api.searchPokemon, action.payload);
    yield put(actions.searchPokemonSuccess(data));
  } catch (error) {
    yield put(actions.searchPokemonFailure(error));
  }
}

export default [
  takeLatest(actions.searchPokemon.toString(), handleSearchPokemon)
];
