IMPORTANT !!!

Try to work on one challenge at a time and observe my solution. This approach will make it easier later to identify any potential bugs.

Challenge (1) - Setup

• create vite project with tailwind

Solution (1) - Setup Vite and Tailwind

Tailwind Docs

• setup vite project

npm create vite@latest comfy-store -- --template react
cd comfy-store

• add tailwind

npm install -D tailwindcss postcss autoprefixer
npx tailwindcss init -p

• rename to tailwind.config.cjs
• add following content

tailwind.config.cjs

/** @type {import('tailwindcss').Config} */
export default {
  content: ['./index.html', './src/**/*.{js,ts,jsx,tsx}'],
  theme: {
    extend: {},
  },
  plugins: [],
};

• remove App.css
• delete contents of index.css
• delete contents of App.jsx
• change title

const App = () => {
  return <div>App</div>;
};
export default App;

• Add the Tailwind directives to your CSS

index.css

@tailwind base;
@tailwind components;
@tailwind utilities;

Tailwind directives are instructions that decide how Tailwind CSS creates the styles for your website. They control the global styles, component styles, and utility classes.

• start the project "npm run dev"

• setup first tailwind classes in App.jsx

• remove StrictMode

  App.jsx

const App = () => {
  return <h1 className='text-7xl font-bold underline'>Tailwind project</h1>;
};
export default App;

        {amount}
      </option>
    );
  });
};

Array.from({ length: number }, (, index) => { ... }): This part uses the Array.from method to create an array of a specific length, determined by the number parameter. The second argument of the Array.from method is a callback function that will be invoked for each element in the array. The underscore () is a placeholder for the current element (which we don't need in this case), and index is the index of the current element.

const amount = index + 1;: Inside the callback function, this line calculates the amount value based on the index. Since the index starts from 0 but you want amount to start from 1, you add 1 to the index.

Solution (36) - Clear Cart, Remove Item and Edit Item

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

const defaultState = {
  cartItems: [],
  numItemsInCart: 0,
  cartTotal: 0,
  shipping: 500,
  tax: 0,
  orderTotal: 0,
};

const getCartFromLocalStorage = () => {
  return JSON.parse(localStorage.getItem('cart')) || defaultState;
};

const cartSlice = createSlice({
  name: 'cart',
  initialState: getCartFromLocalStorage(),
  reducers: {
    addItem: (state, action) => {
      const { product } = action.payload;

      const item = state.cartItems.find((i) => i.cartID === product.cartID);
      if (item) {
        item.amount += product.amount;
      } else {
        state.cartItems.push(product);
      }

      return defaultState;
    },

    removeItem: (state, action) => {
      const { cartID } = action.payload;
      const product = state.cartItems.find((i) => i.cartID === cartID);
      state.cartItems = state.cartItems.filter((i) => i.cartID !== cartID);

      state.numItemsInCart -= product.amount;
      state.cartTotal -= product.price * product.amount;
      cartSlice.caseReducers.calculateTotals(state);
      toast.error('Item removed from cart');
    },
    editItem: (state, action) => {
      const { cartID, amount } = action.payload;
      const item = state.cartItems.find((i) => i.cartID === cartID);
      state.numItemsInCart += amount - item.amount;
      state.cartTotal += item.price * (amount - item.amount);
      item.amount = amount;
      cartSlice.caseReducers.calculateTotals(state);
      toast.success('Cart updated');
    },

    calculateTotals: (state) => {
      state.tax = 0.1 * state.cartTotal;
      state.orderTotal = state.cartTotal + state.shipping + state.tax;
      localStorage.setItem('cart', JSON.stringify(state));
    },
  },
});

export const { addItem, removeItem, editItem, clearCart } = cartSlice.actions;

export default cartSlice.reducer;

state.numItemsInCart += amount - item.amount;

The logic here is to update the total number of items in the cart (state.numItemsInCart) by adjusting it based on the difference between the provided amount and the existing quantity of that item (item.amount). If amount is greater than item.amount, it means that items are being added to the cart. If amount is less than item.amount, it means that items are being removed from the cart. If they are equal, it implies no change to the quantity of that item in the cart.

The result of the subtraction (amount - item.amount) is then added to the current state.numItemsInCart to reflect the new total number of items in the cart.

state.cartTotal += item.price * (amount - item.amount);

In this line, the logic is calculating the change in the total cost of the cart (state.cartTotal) based on the price of the item (item.price) and the change in the quantity of that item (amount - item.amount). This calculation is then added to the current state.cartTotal.

If amount is greater than item.amount, it means more items are being added, so the cost of those additional items (difference between amount and item.amount) is calculated by multiplying it with the price of the item. If amount is less than item.amount, it means items are being removed, so the cost of those removed items is subtracted from the state.cartTotal. If they are equal, there is no change in the cost related to that item.

Challenge (43) - Register User

• API DOCS
• docs - register request
• test in Thunder Client
• setup action in Register
• add action to Register route in App.jsx

Register.js

• Import Dependencies:

  • Import redirect from 'react-router-dom'.
  • Import customFetch from '../utils'.
  • Import toast from 'react-toastify'.

• Define an asynchronous function named action that takes an object with a property named request as its parameter.

• Inside the action function:

  • Use the request object to get form data using the formData method.
  • Convert the form data to an object using Object.fromEntries(formData) and store it in the data variable.

• Use a try block to handle the registration process:

  • Send a POST request using customFetch.post to the /auth/local/register endpoint with the data.
  • If the request is successful:
    • Display a success toast message using toast.success.
    • Redirect the user to the /login page using redirect('/login').

• Use a catch block to handle errors:

  • If an error occurs, extract the error message from the response data, if available, or provide a default error message.
  • Display the error message using toast.error.
  • Return null to indicate that an error occurred.

Challenge (46) - Demo User

• remove defaultValue from inputs

loginAsGuestUser

• Create a function named loginAsGuestUser.
• Mark the function as async to indicate that it contains asynchronous operations.
• Wrap the entire function body in a try block to handle potential errors.
• Inside the try block, use the customFetch.post method to send a POST request.
• Provide the endpoint URL /auth/local.
• Pass an object with identifier and password properties as the request body.
• Assign the response from the customFetch.post call to the response variable.- If the request is successful, dispatch an action (e.g., loginUser) with the response.data.
• Use the toast.success method to display a success message (e.g., 'welcome guest user').
• If the action dispatch and toast success are successful, use the navigate function to navigate to a specific route (e.g., '/').
• If any error occurs within the try block, it will be caught by the catch block.
• Inside the catch block, use console.log to log the error for debugging purposes.
• Display an error message using the toast.error method to notify the user about the login error.

Solution (46) - Demo User

Login.jsx

const Login = () => {
  const dispatch = useDispatch();

Challenge (52) - Orders Page Setup

• create components/OrdersList.jsx (export)
• create loader (import/setup in App.jsx and provide store)
• restrict access to page
• make a request to get all users
• grab all the query params
• return orders and meta

Orders.jsx

1. Import Dependencies:

   • Import the required modules and components from 'react-router-dom', 'react-toastify', and other custom files.

2. Define Loader Function:

   • Create a loader function that takes the store parameter and an object with a request property.
   • Within the loader function:
     • Retrieve the user information from the Redux store.
     • Check if the user is logged in. If not, display a warning toast and redirect to the login page.
     • Parse query parameters from the URL.
     • Use the customFetch utility to make a GET request to the '/orders' endpoint.
     • Handle successful responses by returning the fetched orders data and meta information.
     • Handle errors by displaying appropriate error messages using toast and optionally redirecting if unauthorized.
     • Return null if an error occurs.

3. Define Orders Component:

   • Create a functional component named Orders.
   • Within the component:
     • Return JSX that displays a heading element with the text "orders".

4. Export Loader Function:

   • Export the defined loader function.

5. Export Orders Component:

   • Export the Orders component as the default export of the module.

Challenge (53) - Render Orders

Orders.jsx

• Import Dependencies:

  • Import necessary components and hooks from your project's dependencies.

• Define Component:

  • Define a functional component named Orders.

• Fetch Data:

  • Use the useLoaderData hook to access data from the loader context.
  • Check if the meta.pagination.total value is less than 1 to determine if there are no orders.

• Conditional Rendering:

  • If there are no orders, return a component, such as <SectionTitle />, with a message like 'Please make an order'.

• Orders Rendering:

  • If there are orders, return the following components:
    • <SectionTitle /> with the text 'Your Orders'.
    • <OrdersList /> component to display the list of orders.
    • <PaginationContainer /> component for handling pagination.

• Export Component:

  • Export the Orders component as the default export.

OrdersList.jsx

• Import Dependencies:

  • Import useLoaderData from 'react-router-dom'.
  • Import day and advancedFormat from 'dayjs'.
  • Extend dayjs with the advancedFormat plugin using day.extend(advancedFormat).

• Create the OrdersList component:

  • Inside the component:
    • Use the useLoaderData() hook to get data from loader data.
    • Destructure orders and meta from the loaded data.
    • Return the orders list interface:
      • Display the total number of orders using the meta.pagination.total value.
      • Create a table to display order information.
      • Define table headings: Name, Address, Products, Cost, and Date.
      • Use .map() to iterate over each order and generate table rows:
        • Destructure relevant attributes from the order object.
        • Format the createdAt date using dayjs to display in 'hh:mm a - MMM Do, YYYY' format.
        • Return a table row with the extracted data.

• Export the OrdersList component.

?? === This operator is known as the nullish coalescing operator in JavaScript. It is a logical operator that returns its right-hand side operand when its left-hand side operand is null or undefined, and otherwise returns its left-hand side operand.

In simpler terms, the ?? operator is used to provide a default value for potentially null or undefined variables.
