redux-saga-wrapper v0.1.0

redux-saga-wrapper

A wrapper to write redux reducers and sagas in a minimalist way.

Installation

npm i redux-saga-wrapper --save
# or
yarn add redux-saga-wrapper

How to use

Declare your actions. The ...Failed variant is called if your code throws an error, otherwise the ...Success one is called with the return value of the saga.

const actions = {
  fireRequest: {
    *saga(url) {
      return yield fetch(url);
    },
  },
  fireRequestSuccess: {
    reducer(state, response, action) {
      return {
        response,
        ...state,
      };
    },
  },
  fireRequestFailed: {
    *saga(error, action) {
      alert(`something went wrong: ${error.toString()}`);
    },
  },
};

Create a store and use it as usual.

import { createStore } from 'redux-saga-wrapper';

const initialState = {};
const store = createStore(initialState, actions);

ReactDOM.render(
  <Provider store={store}>
    <App />
  </Provider>,
  document.getElementById('root')
);

Map the actions to your components' props using mapDispatchToProps, and use your actions as you always did!

import { mapDispatchToProps } from 'redux-saga-wrapper';

class App extends React.Component {

  // ...

  componentDidMount() {
    this.props.actions.fireRequest('https://reqres.in/api/users/2');
  }

  // ...
}

export default connect(() => ({}), mapDispatchToProps)(App);

You can also retreive the actions creators in order to call them from a saga or map them manually:

import { actionCreators } from 'redux-saga-wrapper';
