⛳ @brigad/redux-rest-easy

Redux/React/React Native framework generating actions, reducers and selectors to perform network requests

Installation

yarn add @brigad/redux-rest-easy

Or, if you are using npm:

npm install --save @brigad/redux-rest-easy

Problem

At Brigad, we have been extensively using redux and redux-thunk to perform network requests, and store/access the resulting data, and we always felt some pain points, or at least like there were things we could do better:

• We were often copying/pasting a lot of code (along with some logic regarding caching, hooks, etc) from one file to another each time we would create a new resource or action
• Our state was not organized at all, and accessing it was messy and error-prone
• We had a huge caching problem: sometimes performing unnecessary requests, sometimes not performing requests which should have been
• We had no way to know if a given component was performing an action, we only knew if an action was being performed on a given resource

Solution

To solve the problems listed above, redux-rest-easy generates actions, reducers, and selectors, and also manages the state's data and metadata for your network requests. It is easy to use, and to observe via the Redux Devtools.

It also provides sensible defaults, allowing you to use it with almost no configuration, but also to customize anything you would like.

API

import {
  createResource,
  reducer,
  connect,
  reset,
  initializeNetworkHelpers,
} from '@brigad/redux-rest-easy';

• createResource - easily generate then export your actions and selectors from one file
• reducer - plug a single reducer to your state, we handle the rest
• connect - connect your components to the state so the magic can happen
• reset - reset redux-rest-easy's whole state (you can reset parts of the state with actions generated by createResource)
• initializeNetworkHelpers - provide your own network handlers (optional, fallback to included defaults)

Internals

• Actions configuration - defining your actions with createResource
• Actions - actions generated by createResource
• Selectors - selectors generated by createResource

Core principles

1. Preflight checks
2. Actions
3. Reducers
4. Selectors

Minimal Example

// users.js

import { createResource } from '@brigad/redux-rest-easy';

const users = createResource('users')({
  retrieve: {
    method: 'GET',
    url: 'https://my-api.com/users',
    afterHook: () => console.log('Users retrieved successfuly'),
  },
});

const {
  actions: { retrieve: retrieveUsers },
  selectors: {
    resource: { getResource: getUsers },
    retrieve: { request: { isPerforming: isRetrievingUsers } },
  },
} = users;

export { retrieveUsers, getUsers, isRetrievingUsers };

// reducers.js

import { reducer } from '@brigad/redux-rest-easy';

const reducers = combineReducers({
  restEasy: reducer,
});

// UsersList.js

import React, { Component } from 'react';
import { connect } from '@brigad/redux-rest-easy';
import {
  retrieveUsers,
  getUsers,
  isRetrievingUsers,
} from './redux-rest-easy/users';

class UsersList extends Component {
  state = {
    error: false,
  };

  componentDidMount() {
    this.props.retrieveUsers(this.onSuccess, this.onError);
  }

  onSuccess = () => {
    this.setState({ error: false });
  };

  onError = () => {
    this.setState({ error: true });
  };

  render() {
    if (this.props.isRetrievingUsers) {
      return <div>{'Loading...'}</div>;
    }

    if (this.state.error) {
      return (
        <div>{'There seems to be a problem... A network error occured.'}</div>
      );
    }

    return <Users items={this.props.users} />;
  }
}

const mapStateToProps = state => ({
  users: getUsers(state),
  isRetrievingUsers: isRetrievingUsers(state),
});

const mapDispatchToProps = dispatch => ({
  retrieveUsers: (onSuccess, onError) =>
    dispatch(retrieveUsers({ onSuccess, onError })),
});

export default connect(mapStateToProps, mapDispatchToProps)(ConnectedComponent);

Peer dependencies

Redux-rest-easy assumes you are using react (or react-native) and react-redux.

Redux-rest-easy also uses redux-thunk to handle async actions, and therefore requires you to use redux-thunk's middleware in your store. If you are already using redux-thunk, then you have nothing more to do. Else, follow redux-thunk's docs for a quick setup.
