Advanced tools
smitten is an action emitter library. It helps emit actions from virtual dom components in an efficient and elegant manner.
via npm:
$ npm install @action-land/smitten --save
import * as smitten from '@action-land/smitten'
// Logs the `Actions`
const actionListener = action => {
console.log(action)
}
// Creating a new instance
const emitter = smitten.create(actionListener)
// Sample Usage
const component = (emitter) => (
<div>
<button onClick={emitter.of('hello').emit}>Hello</button>
<button onClick={emitter.of('bye').emit}>Bye</button>
<div>
)
// vNode being returned from the component
const vNode = component(emitter)
On clicking on buttons, the actionListener
logs the following Action
s —
// Hello
{type: 'hello', value: [ClickEvent]}
// Bye
{type: 'bye', value: [ClickEvent]}
The value
in this case is the actual click event.
Smitten converts DOM Events into an Action. An Action
has two properties —
type
: Its a string|number
identifier which depicts the originator of event. For example — if an event is fired from the side navigation, the corresponding Action
could have a type
as SIDE_NAV
.value
: Value is the payload that needs to be transmitted via the Action
. In most cases it would be the DOM event. In some cases the value it self could be an Action
. This is especially useful when the nesting of components is really deep and one would like to namespace actions based on the hierarchy of components.This is the constructor function for creating the action emitter. It takes in a single listener and returns an instance of Smitten
.
Usage
import * as smitten from '@action-land/smitten'
const actionListener = event => {
// do something with that event
}
const emitter = smitten.create(actionListener) // returns a Smitten
It takes in a type
which is of type string|number
and returns a new instance of Smitten
. For Eg:
import * as smitten from '@action-land/smitten'
const h0 = smitten.create(listener)
const h1 = h0
.of('A')
.of('B')
.of('C')
It is available on all Smitten
instances. It takes in any value
and based on the type
it dispatches an action
.
