Full Stack E-Commerce App (+8 hours free tutorial)

Hi, I'm Safak. I am a full-stack web developer and I'm sharing open source web projects on my YouTube channel. I want to share my +8 hours "MERN Stack E-Commerce App with an Admin Dashboard" tutorial for free. You can reach the playlist from here.

What technologies are used?

Backend Server: Node.js Express Framework, JWT

Database: MongoDB

Payment Method: Stripe API

Front-End Framework: React.js with hooks

UI library: Styled Components

State Management Library: Redux

Design Part of the E-Commerce App

In this section, we are going to design an e-commerce app using React.js functional components, hooks and Styled Components. For now, we are going to be using a dummy data to display products but in the last part we'll fetch all data from MongoDb using a Rest API

Back-End Part of the E-Commerce App

In this section, we are going to create a Rest API using Express server with MongoDB connection and create necessary models and routes in order to handle CRUD operations. We'll provide the security using JWT and authenticate and authorize users. And also you'll see how easy to get payment using Stripe API

const router = require("express").Router();
const stripe = require("stripe")(process.env.STRIPE_KEY);

router.post("/payment", (req, res) => {
  stripe.charges.create(
    {
      source: req.body.tokenId,
      amount: req.body.amount,
      currency: "usd",
    },
    (stripeErr, stripeRes) => {
      if (stripeErr) {
        res.status(500).json(stripeErr);
      } else {
        res.status(200).json(stripeRes);
      }
    }
  );
});

module.exports = router;

MERN Stack Part of the E-Commerce App

In this section, we are going to combine the API with the UI Design and make our application dynamic. We'll fetch data and make POST requests using axios. And also we'll be covering Redux Toolkit in depth.

import { createSlice } from "@reduxjs/toolkit";

export const productSlice = createSlice({
  name: "product",
  initialState: {
    products: [],
    isFetching: false,
    error: false,
  },
  reducers: {
    //GET ALL
    getProductStart: (state) => {
      state.isFetching = true;
      state.error = false;
    },
    getProductSuccess: (state, action) => {
      state.isFetching = false;
      state.products = action.payload;
    },
    //DELETE
    deleteProductStart: (state) => {
      state.isFetching = true;
      state.error = false;
    },
    deleteProductSuccess: (state, action) => {
      state.isFetching = false;
      state.products.splice(
        state.products.findIndex((item) => item._id === action.payload),
        1
      );
    },
    //UPDATE
    updateProductStart: (state) => {
      state.isFetching = true;
      state.error = false;
    },
    updateProductSuccess: (state, action) => {
      state.isFetching = false;
      state.products[
        state.products.findIndex((item) => item._id === action.payload.id)
      ] = action.payload.product;
    },
    //ADD
    addProductStart: (state) => {
      state.isFetching = true;
      state.error = false;
    },
    addProductSuccess: (state, action) => {
      state.isFetching = false;
      state.products.push(action.payload);
    },
    failure: (state) => {
      state.isFetching = false;
      state.error = true;
    },
  },
});

Awesome tutorial, thanks for the share!! Great resource for people learning express. If you don't mind me asking just to add abit of dialog.... why spin your own express framework opposed to using something like Strapi - strapi.io/?

You've been a great help for learning MERN
