# or
npm run test:coverage:watch
```
## How to create a reducer?
As an example, let's implement a counter component reducer. Files are also available in the repository.
Follow the steps below to implement your first reducer.
1. Create action types constants, in the `constants` directory:
```js
// src/redux/constants/counter.ts
export const actionTypes = {
COUNTER_DECREMENT: 'COUNTER_DECREMENT',
COUNTER_INCREMENT: 'COUNTER_INCREMENT'
}
```
2. Create reducer, in the `reducers` directory:
```js
// src/redux/reducers/counter.ts
import { actionTypes } from '../constants/counter'
type Action = {
type: 'COUNTER_DECREMENT' | 'COUNTER_INCREMENT'
}
const INITIAL_STATE = {
counter: 0
}
export const counterReducers = (state = INITIAL_STATE, action: Action) => {
switch (action.type) {
case actionTypes.COUNTER_DECREMENT:
return {
...state,
counter: state.counter - 1
}
case actionTypes.COUNTER_INCREMENT:
return {
...state,
counter: state.counter + 1
}
default:
return state
}
}
```
3. Import reducer on reducers main file:
```js
// src/redux/reducers/index.ts
import { combineReducers } from 'redux'
import { counterReducers } from './counter'
export const reducers = combineReducers({
// ...
counterReducers
})
```
4. Create action types methods, in the `actions` directory:
```js
// src/redux/actions/counter.ts
import { actionTypes } from '../constants/counter'
export const actions = {
decrement: () => ({
type: actionTypes.COUNTER_DECREMENT
}),
increment: () => ({
type: actionTypes.COUNTER_INCREMENT
})
}
```
5. Create selectors, in the `selectors` directory:
```js
// src/redux/selectors/counter.ts
import { RootStateOrAny } from 'react-redux'
export const selectors = {
getCounter: (state: RootStateOrAny) => state.counterReducers.counter
}
```
6. Create a custom hook, in the `hooks` directory:
```js
// src/hooks/useCounter/index.tsx
import { useSelector, useDispatch } from 'react-redux'
import { actions } from '../../redux/actions/counter'
import { selectors } from '../../redux/selectors/counter'
export function useCounter () {
const counter = useSelector(selectors.getCounter)
const dispatch = useDispatch()
const handleDecrement = () => dispatch(actions.decrement())
const handleIncrement = () => dispatch(actions.increment())
return { counter, handleDecrement, handleIncrement }
}
```
7. Import custom hook in the component:
```js
// src/components/Counter/index.tsx
import { useCounter } from '../../hooks/useCounter'
export function Counter () {
const { counter, handleDecrement, handleIncrement } = useCounter()
return (
Counter: {counter}
Decrement
Increment
)
}
```
