How to create a new Saga?

To create a new saga, you need to stay at the root of the project and enter this command in your terminal:

neutron add:saga <sagaName>

Usage command example

neutron add:saga tools

After the execution, this command will create a new file in ./src/store/sagas and, if it does not exists, will also create a new file in ./src/store/ducks.


/* #FILE: ./src/store/sagas/tools.js */
import { call, put } from 'redux-saga/effects';
import api from '@/services/api';
import ToolsActions from '@/store/ducks/tools';
export function* getToolsRequest() {
try {
const endpoint = '/tools';
const { data } = yield call(api.get, endpoint);
yield put(ToolsActions.getToolsSuccess(data));
} catch (error) {
yield put(ToolsActions.getToolsFailure());

Register Sagas

This step is very important to register your sagas to listen all calls related to the configured types.

/* #FILE: ./src/store/ducks/sagas.js */
import { all, takeLatest } from 'redux-saga/effects';
import { ToolsTypes } from '@/store/ducks/tools'; // example
import { getToolsRequest } from './tools'; // example
export default function* rootSaga() {
yield all([
takeLatest(ToolsTypes.GET_TOOLS_REQUEST, getToolsRequest), // example

We decided to use takeLatest to ensure that only the last call is executed. For more information on other options, you can check the Redux-Saga - API Reference
