4 months ago admin Reactjs

In the third part of this tutorial, we will start coding the front end, first, we will install the packages we need and later we will create the components and routes.

Install the packages

All the packages we will need are below you can add them to your 'package.json' file and run npm install.

show or hide the code

                                                    
                                                                                                                {
  "name": "frontend",
  "private": true,
  "version": "0.0.0",
  "type": "module",
  "scripts": {
    "dev": "vite",
    "build": "vite build",
    "lint": "eslint . --ext js,jsx --report-unused-disable-directives --max-warnings 0",
    "preview": "vite preview"
  },

  }
}

Add the store

Next, inside src add a new folder redux inside add a new folder store inside add a new file 'index.js' that will hold the store we need.

the image below contains the file structure of the front end:

show or hide the code

                                                        
                                                                                                                        import { configureStore } from '@reduxjs/toolkit'
import cartReducer from '../slices/cartSlice'


const store = configureStore({
    reducer: {
        cart: cartReducer
    }
})

export default store

Create the cart slice

Next, inside redux add new folder slices inside add a new file 'cartSlice.js that will hold all the cart actions we need.

show or hide the code

                                                        
                                                                                                                        import { createSlice } from "@reduxjs/toolkit"
import { toast } from 'react-toastify'


const initialState = {
    cartItems: []
}

export const cartSlice = createSlice({
    name: 'cart',
    initialState,
    reducers: {
        addToCart(state, action) {
            const item = action.payload
            let existingProduct = state.cartItems.find(product => product.id === item.id)
            if(existingProduct) {
                existingProduct.quantity += 1
                toast.success('Product quantity increased')
            }else{
                item.quantity = 1
                state.cartItems = [item, ...state.cartItems]
                toast.success('Product added to the cart')
            }
        },
        incrementQ(state, action) {
            const item = action.payload
            let existingProduct = state.cartItems.find(product => product.id === item.id)
            existingProduct.quantity += 1
            toast.success('Product quantity increased')
        },
        decrementQ(state, action) {
            const item = action.payload
            let existingProduct = state.cartItems.find(product => product.id === item.id)
            existingProduct.quantity -= 1
            if(existingProduct.quantity === 0){
                state.cartItems = state.cartItems.filter(product => product.id !== existingProduct.id)
            }
            toast.success('Product quantity decreased')
        },
        removeFromCart(state, action) {
            const item = action.payload
            state.cartItems = state.cartItems.filter(product => product.id !== item.id)
            toast.success('Product removed from the cart')
        }
    }
})

export const { addToCart, incrementQ, decrementQ, removeFromCart} = cartSlice.actions

const cartReducer = cartSlice.reducer

export default cartReducer

Add routes

Inside the file App.jsx let's add the code below:

show or hide the code

                                                        
                                                                                                                        import Home from "./components/Home"
import { BrowserRouter, Routes, Route } from 'react-router-dom'
import Header from "./components/layouts/Header"
import store from "./redux/store"
import { Provider } from 'react-redux'
import Cart from "./components/cart/Cart"
import PaymentSuccess from "./components/payments/PaymentSuccess"

function App() {
  return (
    <Provider store={store}>
      <BrowserRouter>
        <Header />
        <Routes>
          <Route path="/" element={<Home />} />
          <Route path="/cart" element={<Cart />} />
          <Route path="/payment/success" element={<PaymentSuccess />} />
        </Routes>
      </BrowserRouter>
    </Provider>
  )
}

export default App

Update the file main.jsx

Inside the file main.jsx let's add the code below:

show or hide the code

                                                        
                                                                                                                        import React from 'react'
import ReactDOM from 'react-dom/client'
import App from './App.jsx'
import 'bootstrap/dist/css/bootstrap.min.css'
import 'bootstrap/dist/js/bootstrap.min.js'
import 'bootstrap-icons/font/bootstrap-icons.css'
import 'react-toastify/dist/ReactToastify.css'
import './index.css'
import { ToastContainer } from 'react-toastify'

ReactDOM.createRoot(document.getElementById('root')).render(
  <React.StrictMode>
    <ToastContainer position="top-right" />
    <div className="container">
      <App />
    </div>
  </React.StrictMode>,
)
