[![Build Status](https://travis-ci.org/wellguimaraes/actionware.svg?branch=master)](https://travis-ci.org/wellguimaraes/actionware)
[Redux](http://redux.js.org/) with less boilerplate, actions statuses and controlled side-effects in a single shot.
- no more **action creators** and **action types**, just **actions¹** and **reducers**
- **actions** dispatch their result automatically
- **error status** for every action with no extra code
- **busy status** for every async action (yep, no extra code!)
- **cancellable** actions**¹** With Actionware, **actions** have a different meaning: they're just functions which execution generate events.
See [usage](#usage) section to better understand.###### Extra power
Wanna have state selectors/getters in a decent way? Use it combined with **[Stateware](https://github.com/wellguimaraes/stateware)** lib.## Setup
#### Install it
- Yarn: `yarn add actionware`
- NPM: `npm i actionware --save`#### After creating your Redux store, let Actionware know your store instance. Optionally you
can define custom action types prefix and suffixes:
```js
import * as actionware from 'actionware';actionware.setup({
store,
defaultPrefix, // default: 'actionware:'
errorSuffix, // default: ':error'
cancelSuffix, // default: ':cancel'
busySuffix // default: ':busy'
});
```#### Add actionware reducer to your root reducer:
To make Redux store react to **busy** and **error** status changes,
make sure you add the Actionware reducer into your root reducer.
```js
import { combineReducers } from 'redux';
import { actionwareReducer } from 'actionware';const rootReducer = combineReducers({
actionware: actionwareReducer,
// your reducers
});
```## Usage
#### Simple actions
```js
export function incrementCounter() { }
```#### Async actions
Whatever you return will be the action payload```js
// Note that the store is always the last arg
export async function loadUsers(arg1, arg2, argN, store) {
const response = await fetch('/my/api/users');
return response.json();
}
```#### Invoke any action
Use `call` to invoke an action and let Actionware handle
the execution lifecycle (managing error and busy statuses, notifying listeners, etc).
```js
import { call } from 'actionware';call(loadUsers, arg1, arg2, argN);
```#### Cancel an action execution
```js
import { call } from 'actionware';const actionCall = call(loadUsers, arg1, arg2, argN);
actionCall.cancel()
```To cancel inner calls or other async executions, use `setExtra` inside an async action
to keep information needed and use them on a cancellation listener:
```js
import { call, onCancel} from 'actionware';
import api from './path/to/api';// Don't use arrow functions here,
// otherwise a context value can't be set
export async function someAction() {
const apiCall = api.get('/some/endpoint')
const anotherActionCall = call(anotherAction, 'someParam')
this.setExtra({ apiCall })
this.setExtra({ anotherActionCall }) // you can call it multiple times
const apiResponse = await apiCall
const anotherResponse = await anotherActionCall
// ...
return apiResponse.data
}export async function anotherAction() {
// ...
}onCancel(someAction, ({ extras }) => {
// Check if the action execution is still cancellable
if (extras.anotherActionCall.canBeCancelled)
extras.anotherActionCall.cancel()
// Cancel the api call...
})
```#### Clear action error
```js
import { clearError } from 'actionware'export async function someAction() {
// ...
}clearError(someAction)
```#### Reducers:
```js
import { createReducer } from 'actionware';
import { loadUsers, persistUser, incrementCounter } from 'path/to/actions';const initialState = { users: [], count: 0 };
export default createReducer(initialState)
.on(loadUsers,
(state, users) => ({ ...state, users }))
.on(incrementCounter,
(state) => ({ ...state, counter: state.counter + 1 }))
// Bind legacy action types
.on('OLD_ACTION_TYPE',
(state, payload) => { /* return new state */ })
// Bind multiple actions to the same handler
.on(
someAction,
anotherAction,
(state, payload) => { /* return new state */ })
// Actionware handles errors, cancellation and 'before' events,
// but if you need to do something else
.onError(persistUser,
(state, error, ...args) => { /* return new state */ })
.onCancel(loadUsers,
(state, extras, ...args) => { /* return new state */ })
.before(loadUsers,
(state, ...args) => { /* return new state */ });
```#### Busy and failure statuses for all your actions:
```js
import { getError, isBusy } from 'actionware';
import { loadUsers } from 'path/to/userActions';// Whenever needed...
isBusy(loadUsers);
getError(loadUsers);
```#### Use listeners to manage side effects:
Note that busy listeners are called when busy status changes.
```js
import { onSuccess, onError, onCancel, before, beforeAll } from 'actionware';
import { createUser } from 'path/to/actions';// global success listener
onSuccess(({ action, args, payload, store }) => eventTracker.register(action.name));// per action success listener
onSuccess(createUser, ({ args, payload, store }) => history.push(`/users/${user.id}`));// error listeners
onError(({ action, args, error }) => { /* ... */ });
onError(createUser, ({ args, error }) => { /* ... */ });// cancellation listeners
onCancel(({ action, args, extras }) => { /* ... */ });
onCancel(createUser, ({ args, extras }) => { /* ... */ });// before listeners
// NOTE: 'beforeAll' is just an alias for 'before'
beforeAll(({ action, args, store}) => { /* ... */ });
before(createUser, ({ args, store }) => { /* ... */ });
```#### Interaction-dependent flows
When you have "complex" flows that depend on some interaction to start or continue,
you can use `next` to wait for some action completion in this fashion:
```js
import { call, next } from 'actionware';
import { login, showTip, acknowledgeTip } from 'path/to/actions';export async function appEducationFlow() {
// Wait for the next successful login
await next(login);
call(showTip, 'headerButtons');
await next(acknowledgeTip);
history.redirect('/some/route');
call(showTip, 'sideMenu');
await next(acknowledgeTip);
}// At some point, start the flow
appEducationFlow();
```## Usage with React
#### Inject actions and status into components as props
By using `withActions` to wrap a component, actions are injected into it as props
and can be invoked without using `call`.
```js
import * as React from 'react';
import { connect } from 'react-redux';
import { withActions, isBusy, getError } from 'actionware';
import { loadUsers } from 'path/to/actions';const actions = { loadUsers };
const mapStateToProps = ({ company }) => ({
users : company.users,
loading : isBusy(loadUsers),
error : getError(loadUsers)
});@connect(mapStateToProps)
@withActions(actions)
class MyConnectedComponent extends Component {
componentDidMount() {
this.props.loadUsers();
}
render() {
const { loading, error } = this.props;
if (loading) return (Loading...);
if (error) return (Failed to load users...);
return (
{ users.map(it => ) }
);
}
}export default MyConnectedComponent
```#### Without injecting actions as props
In case you prefer not injecting actions as props into your component, you can use `createActions` this way:
```js
import { createActions } from 'actionware'const actions = createActions('optionalPrefix:', {
someAction,
anotherAction
})const MyComponent = () => (
)```
## Testing
#### Mock `call` and `next` functions
While testing, you're able to replace the `call` and `next` functions by custom
spy/stub to simplify tests.
```js
import { mockCallWith, mockNextWith } from 'actionware';const callSpy = sinon.spy();
const nextStub = sinon.stub().returns(Promise.resolve());mockCallWith(callSpy);
mockNextWith(nextStub);// Get back to default behavior
mockCallWith(null);
mockNextWith(null);
```#### Reducers
For testing reducers, you can do the following:```js
import { successType } from 'actionware';
import { loadUsers } from 'path/to/userActions';
import usersReducer from 'path/to/usersReducer';describe('usersReducer', () => {
describe('on loadUsers', () => {
it('should replace the "users" array with the loaded users', () => {
const currentState = { users: [ ] };
const loadedUsers = [ 'John Doe', 'Joane Doe', 'Steve Gates' ];// Call reducer with currentState and a regular Redux action
const newState = usersReducer(
currentState,
{ type: successType(loadUsers), payload: loadedUsers }
);
expect(newState.items).to.equals(loadedUsers);
});
});
});
