'Redux - API is being called multiple times (Redux Thunk)
I am using Next.js and Redux as a state management. Everything is working perfectly fine except one thing and that is API calls. What I mean by this is that API is being called multiple times even though I dispatched it just once. When I go and see in the network tab in Google Chrome, I see multiple calls being called.
I am also using Redux Thunk and Redux Toolkit:
store
import { configureStore } from "@reduxjs/toolkit";
import layoutSlice from "./layoutSlice";
export const store = configureStore({
reducer: {
layout: layoutSlice,
},
});
layoutSlice
import { createSlice, createAsyncThunk } from "@reduxjs/toolkit";
import axios from "axios";
const BASE_URL = "http://localhost:1337";
export const getHeaderData = createAsyncThunk(
"layout/getHeaderData",
async () => {
const response = await axios.get(
`${BASE_URL}/api/navigations?populate=*&sort=id`
);
return response.data;
}
);
export const getFooterData = createAsyncThunk(
"layout/getFooterData",
async () => {
const response = await axios.get(
`${BASE_URL}/api/footers?populate[ContactForm][populate]=*&populate[Links][populate]=*&populate[Info][populate]=*`
);
return response.data;
}
);
const initialState = {
header: [],
footer: [],
isLoadingHeader: false,
isLoadingFooter: false,
};
const layoutSlice = createSlice({
name: "layout",
initialState,
extraReducers: {
[getHeaderData.pending]: (state) => {
state.isLoadingHeader = true;
},
[getHeaderData.fulfilled]: (state, action) => {
state.header = action.payload;
state.isLoadingHeader = false;
},
[getHeaderData.rejected]: (state) => {
state.isLoadingHeader = false;
},
[getFooterData.pending]: (state) => {
state.isLoadingFooter = true;
},
[getFooterData.fulfilled]: (state, action) => {
state.footer = action.payload;
state.isLoadingFooter = false;
},
[getFooterData.rejected]: (state) => {
state.isLoadingFooter = false;
},
},
});
export default layoutSlice.reducer;
generalLayout (where the API is called)
import React, { useEffect, useState } from "react";
import { Header, Footer } from "../components";
import { useDispatch, useSelector } from "react-redux";
import { getHeaderData, getFooterData } from "../redux/layoutSlice";
const GeneralLayout = ({ children }) => {
const { isLoadingHeader, isLoadingFooter } = useSelector(
(state) => state.layout
);
const dispatch = useDispatch();
useEffect(() => {
dispatch(getHeaderData());
dispatch(getFooterData());
}, []);
if (isLoadingHeader === true || isLoadingFooter === true) {
return <div>Loading...</div>;
}
return (
<>
<Header />
{children}
<Footer />
</>
);
};
export default GeneralLayout;
I am also using Strapi (dont mind the query for the API call, it works for me so I do not think the problem is there, at least it should not be)
