Explore the mounting phase by tracing constructor, render, and componentDidMount execution, learn proper state initialization, props handling, and why avoid http requests or setState in render.

Explore the updating phase of React lifecycle, where changes to props or state trigger render and componentDidUpdate, diff the virtual dom, and conditionally fetch data to avoid performance issues.

Explore the unmounting phase in React by using componentWillUnmount to clean up when a component is removed or navigates away, including canceling http requests.

Explore how React manages parent and child lifecycles during mounting, updating, and unmounting, using a shopping cart and product components to illustrate lifecycle method order.

Demonstrates the error handling phase in React by using componentDidCatch to capture errors and info (component stack) from child components, logging details to localStorage for debugging.

Demonstrate building a React login form with Bootstrap, including email and password inputs bound to component state. Explain two-way binding via onChange and initializing state in the login component.

Learn how to implement two-way binding in React by syncing text box input to state with onChange and setState, handling asynchronous updates via the event target value.

learn how to build a login form in React by updating state on input changes, checking dummy credentials on submit, and rendering a success or invalid login message.

Learn how ajax fetches data in the background from a json server acting as a fake rest api, and update React state to render products from localhost:5000/products.

Learn how to simplify promise-based code with async and await, using fetch to perform a get request, converting response to json, and updating state with the resulting products array.

Build a dynamic React login form that uses async/await to fetch credentials from an http json server by sending email and password as query parameters and validating by response length.

Create a react app with basic routing using react-router-dom, map paths like /, /dashboard, /customers, and /cart to respective components, render a navbar, and use exact to avoid unintended matches.

Learn how to handle invalid URLs with a 404 page in React routing by creating a no match page, using a wildcard path, and avoiding multiple renders with switch.

wrap routes in a switch to ensure only one route renders at a time, importing switch from React Router, so customers, shopping cart, dashboard, and login pages load correctly.

learn to build a react spa navigation bar using react-router-dom link components for login, dashboard, customers, and shopping cart; routes match app.jsx, with bootstrap container fluid layout.

Highlight the active route in React routing by replacing links with NavLink, using the active className on nav links, with exact true for exact matches, and styling .nav-link.active in index.css.

Store isLoggedIn in app state, pass it to the navbar, and render login or dashboard, customers, and shopping cart links accordingly.

Expose an update is logged in status method in the app component and pass it to the login component via route render to toggle is logged in after successful login.

Programmatically navigate between login and dashboard by creating a global history object with history.js, switching from browserRouter to Router, and using history.replace after a successful login.

Create a logout link in the navbar that shows when logged in, triggers on logout click to prevent default, updates the app's login status, and redirects to login with history.replace('/').

Create a React sidebar component using Bootstrap grid (3/9), render conditionally after login, and navigate with React Router nav links to dashboard, customers, and shopping cart, with active link highlighting.
