Redux Actions
Actions are the only source of information for the store as per Redux official documentation.
It carries a payload of information from your application to store. As discussed earlier,
actions are plain JavaScript object that must have a type attribute to indicate the type of action performed.
Actions are the only way by which your application can interact with the store.
Redux Action carry some information from your app to the redux store.
We also learn,Actions are the plain javascript objects.
They must however have a 'type' property that indicates the type of action being performed.
the 'type' property is typically defined as string constants.
Example:
index.js
const BUY_CAKE = 'BUY_CAKE'
function buyCake(){
return{
type : BUY_CAKE,
info: 'First redux action'
}
}
In the above example,we have created our action for the cake shop application.
First,we define a string constant that indicates the type of the action i.e,'BUY_CAKE'.
During this,we will avoid the spelling mistake while using the action.
Next,we define our action.Remember an action is an object that has a type property.
And like this, we have just created our first Action in redux.
Action Creator:
As the name indicates,an action Creator simply creates an action.In terms of code,an action creator
is a function that returns an action.So,to implement the action creator,we create a function which returns the action.
In the above example,function buyCake() acts as an action creator.
