Reactjs Ecommerce Open Source Project with Github Code [Nov 2022]

Posted Dec 24, 2022

Welcome to the #react10 Day 9 challenge.

In this tutorial we will develop a shopping website aka Reactjs Ecommerce (with open source code) project using Reactjs Context API. This tutorial will teach you to develop an ecommerce website with basic functionality i.e. show products, add to cart, review and checkout and place & view orders.
For routing we will use 'react-router-dom' npm package.

Key Points

Context API used as global store (not redux)
Mock data used in a json file (will not make any API calls to fetch it)

Demo

Get Github Code

Pre-requisites

Code Editor (like VS Code)
React basic knowledge
Basic knowledge of HTML & CSS

Lets Begin!

Open terminal in the vs code and run these commands,

npx create-react-app shoppinn
cd shoppinn
npm start

After doing all of this, your UI should look like,

Reactjs Ecommerce Open Source

Folder Structure

Add 'components', 'context' & 'mockData' folder in the 'src' folder.
Follow the below images to create same folder structure along with the js and css files.

Note - I have removed few files which 'create-react-app' util gives us by default.

Reactjs Ecommerce Open Source

Lets develop our Ecommerce App!

To develop this kind of project it has to have lots of react components to modularize our project.
For example, 'ItemList.js' component to show list of 'Item.js' component in 'HomePage.js' component.
We will use 'mockData' folder to have dummy data of products in a 'items.json' file. And 'context' folder to have Context API's global store. Lets begin by putting code in each file on by one.

1. GlobalState.js

import React, { createContext, useReducer } from "react";
import AppReducer from "./AppReducer";

const initialState = {
  cart: [],
  orders: [],
};

export const GlobalContext = createContext(initialState);

export const GlobalProvider = ({ children }) => {
  const [state, dispatch] = useReducer(AppReducer, initialState);

  const addItemToCartList = (item) => {
    dispatch({
      type: "ADD_ITEM_IN_CART",
      payload: item,
    });
  };

  const removeItemFromCartList = (item) => {
    dispatch({
      type: "REMOVE_ITEM_IN_CART",
      payload: item,
    });
  };

  const clearCart = () => {
    dispatch({
      type: "CLEAR_CART",
    });
  };

  const addItemToOrderList = (item) => {
    dispatch({
      type: "ADD_ITEM_IN_ORDER",
      payload: item,
    });
  };

  const removeItemFromOrderList = (item) => {
    dispatch({
      type: "REMOVE_ITEM_IN_ORDER",
      payload: item,
    });
  };

  return (
    <GlobalContext.Provider
      value={{
        cart: state.cart,
        orders: state.orders,
        addItemToCartList,
        removeItemFromCartList,
        clearCart,
        addItemToOrderList,
        removeItemFromOrderList,
      }}
    >
      {children}
    </GlobalContext.Provider>
  );
};

2. AppReducer.js

import React from "react";

export default (state, action) => {
  switch (action.type) {
    case "ADD_ITEM_IN_CART":
      return {
        ...state,
        cart: [action.payload, ...state.cart],
      };
    case "REMOVE_ITEM_IN_CART":
      return {
        ...state,
        cart: state.cart.filter((item) => item.id !== action.payload.id),
      };
    case "CLEAR_CART":
      return {
        ...state,
        cart: [],
      };
    case "ADD_ITEM_IN_ORDER":
      return {
        ...state,
        orders: [action.payload, ...state.orders],
      };
    case "REMOVE_ITEM_IN_ORDER":
      return {
        ...state,
        orders: state.orders.filter(
          (order) => order.orderId !== action.payload.id
        ),
      };
    default:
      return state;
  }
};

3. index.js

            and scrambled it to make a type specimen book. It has survived not
            only five centuries, but also the leap into electronic typesetting,
            remaining essentially unchanged.

      </ul>
    </div>
  );

export default Navbar;

To give you an option to change this project theme/css and to personalize your project in your own way we have skipped the css code as part of this tutorial. However, if you love our UI design you can grab the css code and 'mockData/items.json' from our github(please grab it from footer). And after doing all of this, you are done with your own reactjs ecommerce open Source web app.
