I am creating a simple game react app and when I try to add a player to my players list it seems to be creating an infinite loop and I'm not sure why. I tried to use useEffect to render the player list on initial load but that didn't help so I removed it for now to simplify. Any ideas what I could be doing differently?
App.js
import React, { useEffect } from 'react'
import {useDispatch, useSelector} from 'react-redux';
import './App.css';
import {setPlayerName, increaseCurrentPlayerId, decreaseCurrentPlayerId, addPlayerToList} from './redux/reducers/playerReducer';
function App() {
const dispatch = useDispatch()
const playerName = useSelector(state => state.playerName);
const playerList = useSelector(state => state.playerList);
const currentPlayerId = useSelector(state => state.currentPlayerId)
// dispatch(addPlayerToList('Test'))
const addPlayer = (player) => {
dispatch(addPlayer(player))
dispatch(setPlayerName(''))
}
const renderPlayerList = () => {
if (playerList.length < 1) {
return (
<div>
No Players
</div>
)
} else {
return (
playerList.map(p =>
<p>p.name</p>
)
)
}
}
return (
<div className="App">
<input
type='text'
name='playerName'
onChange={({ target }) => dispatch(setPlayerName(target.value))}
required
/>
Name<br/>
<button type='button'
onClick={() => addPlayer(playerName)}
>
Add Player</button> <br />
<br />
</div>
);
}
export default App;
playerReducer.js
export const playerNameReducer = (state = '', action) => {
switch (action.type) {
case 'SET_PLAYER_NAME':
return action.data;
default:
return state;
}
};
export const playerListReducer = (state = null, action) => {
switch (action.type) {
case 'ADD_PLAYER':
return [...state, action.data];
default:
return state;
}
};
Action Creators
export const setPlayerName = playerName => {
return {
type: 'SET_PLAYER_NAME',
data: playerName,
};
};
export const addPlayerToList = player => {
return {
type: 'ADD_PLAYER',
data: player,
};
};

addPlayer calls itself
const addPlayer = (player) => {
dispatch(addPlayer(player))
}
