@truefit/bach-redux v2.1.0

@truefit/bach-redux

This library brings redux connectivity to components composed with @truefit/bach allowing you to add actions and selectors directly in your enhancer chain, rather than needing an extra HOC for connect.

Installation

npm install @truefit/bach-redux redux react-redux

or

yarn add @truefit/bach-redux redux react-redux

Enhancers

withAction

Allows you to specify a single action creator to be connected to the store. See withActions for more discussion

Enhancer Signature

Example

Typescript

import React from 'react';
import {compose} from '@truefit/bach';
import {withAction} from '@truefit/bach-redux';
import {PayloadAction} from '@reduxjs/toolkit';

const ADD_TODO = 'ADD_TODO';
const addToDo = (note: string): PayloadAction<string> => ({
  type: ADD_TODO,
  payload: note,
});

type Props = {
  addToDo: (note: string) => void;
};

const WithAction = ({addToDo}: Props) => (
  <div>
    <h1>withAction</h1>
    <button
      type="button"
      onClick={() => {
        addToDo('New ToDo from withAction');
      }}
    >
      Click Me
    </button>
  </div>
);

export default compose(withAction<Props>('addToDo', addToDo))(WithAction);

Javascript

import React from 'react';
import {compose} from '@truefit/bach';
import {withAction} from '@truefit/bach-redux';

const ADD_TODO = 'ADD_TODO';
const addToDo = note => ({
  type: ADD_TODO,
  payload: note,
});

const WithAction = ({addToDo}) => (
  <div>
    <h1>withAction</h1>
    <button
      onClick={() => {
        addToDo('New ToDo from withAction');
      }}
    >
      Click Me
    </button>
  </div>
);

export default compose(
  withAction('addToDo', addToDo)
)(WithAction);

withActions

Allows you to specify a map of action creators to be connected to the store.

Side Note This functionality was removed from the react-redux standard hooks (https://react-redux.js.org/next/api/hooks#removed-useactions). That said, we don't agree with the reasoning. Although using dispatch directly in your components does match standard hooks more closely, that doesn't mean that it is better code. In our opinion, it leads to less readable code - thus we have included these enhancers in this library.

Enhancer Signature

Example

Typescript

import React from 'react';
import {compose} from '@truefit/bach';
import {withActions} from '@truefit/bach-redux';
import {PayloadAction} from '@reduxjs/toolkit';

const ADD_TODO = 'ADD_TODO';

const addToDo1 = (note: string): PayloadAction<string> => ({
  type: ADD_TODO,
  payload: note,
});

const addToDo2 = (note: string): PayloadAction<string> => ({
  type: ADD_TODO,
  payload: `Too: ${note}`,
});

type Props = {
  addToDo1: (note: string) => void;
  addToDo2: (note: string) => void;
};

const WithActions = ({addToDo1, addToDo2}: Props) => (
  <div>
    <h1>withActions</h1>
    <button
      type="button"
      onClick={() => {
        addToDo1('New ToDo 1 from withActions');
      }}
    >
      Click Me
    </button>
    <button
      type="button"
      onClick={() => {
        addToDo2('New ToDo 2 from withActions');
      }}
    >
      Click Me
    </button>
  </div>
);

export default compose(
  withActions<Props>({addToDo1, addToDo2}),
)(WithActions);

Javascript

import React from 'react';
import {compose} from '@truefit/bach';
import {withActions} from '@truefit/bach-redux';

const ADD_TODO = 'ADD_TODO';

const addToDo1 = note => ({
  type: ADD_TODO,
  payload: note,
});

const addToDo2 = note => ({
  type: ADD_TODO,
  payload: `Too: ${note}`,
});

const WithActions = ({addToDo1, addToDo2}) => (
  <div>
    <h1>withActions</h1>
    <button
      onClick={() => {
        addToDo1('New ToDo 1 from withActions');
      }}
    >
      Click Me
    </button>
    <button
      onClick={() => {
        addToDo2('New ToDo 2 from withActions');
      }}
    >
      Click Me
    </button>
  </div>
);

export default compose(withActions({addToDo1, addToDo2}))(WithActions);

withDispatch

Returns a reference to the dispatch function from the Redux store. You may use it to dispatch actions as needed.

Enhancer Signature

There are no parameters for this enhancer.

Example

import React from 'react';
import {compose} from '@truefit/bach';
import {withDispatch} from '@truefit/bach-redux';
import {Dispatch} from 'redux';

const ADD_TODO = 'ADD_TODO';

type Props = {
  dispatch: Dispatch;
};

const WithDispatch = ({dispatch}: Props) => (
  <div>
    <h1>withDispatch</h1>
    <button
      type="button"
      onClick={() => {
        dispatch({
          type: ADD_TODO,
          payload: 'New ToDo from withDispatch',
        });
      }}
    >
      Click Me
    </button>
  </div>
);

export default compose(withDispatch())(WithDispatch);

import React from 'react';
import {compose} from '@truefit/bach';
import {withDispatch} from '@truefit/bach-redux';

const ADD_TODO = 'ADD_TODO';

const WithDispatch = ({dispatch}) => (
  <div>
    <h1>withDispatch</h1>
    <button
      onClick={() => {
        dispatch({
          type: ADD_TODO,
          payload: 'New ToDo from withDispatch',
        });
      }}
    >
      Click Me
    </button>
  </div>
);

export default compose(withDispatch())(WithDispatch);

React-Redux Hook

useDispatch

withSelector

Allows you to extract data from the Redux store state, using a selector function.

Enhancer Signature

Example

Typescript

import React from 'react';
import {compose} from '@truefit/bach';
import {withSelector} from '@truefit/bach-redux';
import {ApplicationState} from '../../../rootReducer';

const todoSelector = (state: ApplicationState) => state.features.example.test;

type Props = {
  todos: string[];
};

const WithSelector = ({todos}: Props) => (
  <div>
    <h1>withSelector</h1>
    <ul>
      {todos.map(todo => (
        <li key={todo}>{todo}</li>
      ))}
    </ul>
  </div>
);

export default compose(
  withSelector<Props, string[]>('todos', todoSelector)
)(WithSelector);

Javascript

import React from 'react';
import {compose} from '@truefit/bach';
import {withSelector} from '@truefit/bach-redux';

const WithSelector = ({todos}) => (
  <div>
    <h1>withSelector</h1>
    <ul>
      {todos.map(todo => (
        <li key={todo}>{todo}</li>
      ))}
    </ul>
  </div>
);

export default compose(
  withSelector('todos', (state, props) => state.features.bachRedux.todo),
)(WithSelector);

React-Redux Hook

useSelector

withStore

Returns a reference to the same Redux store that was passed in to the component. This enhancer should probably not be used frequently. Prefer withSelector() as your primary choice.

Enhancer Signature

There are no parameters for this enhancer.

Example

Typescript

import React from 'react';
import {compose} from '@truefit/bach';
import {withStore} from '@truefit/bach-redux';
import {Store} from 'redux';

type Props = {
  store: Store;
};

const WithStore = ({store}: Props) => (
  <div>
    <h1>withStore</h1>
    <ul>
      {store.getState().features.example.test.map((todo: string) => (
        <li key={todo}>{todo}</li>
      ))}
    </ul>
  </div>
);

export default compose(
  withStore()
)(WithStore);

Javascript

import React from 'react';
import {compose} from '@truefit/bach';
import {withStore} from '@truefit/bach-redux';

const WithStore = ({store}) => (
  <div>
    <h1>withStore</h1>
    <ul>
      {store.getState().features.bachRedux.todo.map(todo => (
        <li key={todo}>{todo}</li>
      ))}
    </ul>
  </div>
);

export default compose(
  withStore(),
)(WithStore);
