Using Child routes with React Router

 

Modern way to do React Router:

(Note I am using React-router-dom 6.10) Using Child routes can greatly enhance the organization, maintainability, and functionality of your routing configuration. Here's why and how to use child routes.


1) Nested Layouts:

Child routes let you set up nested layouts. For example, if you have a main layout like HomeLayout that includes shared elements (like a header, footer, or navigation bar), you can use child routes to nest different pages within this layout.


In this example, HomeLayout will render for all the child routes (Landing, Register, Login). 


2) index property: 

Child routes let you set a default route for a layout, which is great for defining a landing page for a section of your app. In the example above, Landing will be the default if the user goes to the root path ('/'). Just make sure you add <Outlet /> to the parent element <HomeLayout /> to display all the child routes like in the example below.



3) Nested Layouts:

Child routes let you set different error boundaries for different parts of your app. In the first example, the errorElement at the root route level handles errors for all the nested routes. So if the user types in a wrong route, the <Error /> page will render.


4) Cleaner Code:

Using child routes keeps your routing setup organized and easier to manage. Instead of having a long list of routes, you can group related ones together, which is super helpful for larger apps.

Lifecycle of React components

 What I learned today : how to use lifecycle of React components without using class When we talk about the lifecycle of react components, we are talking about Mounting Unmounting Updating The reason it is important to understand is because there are side effects that we need to perform during the lifecycle of a component such as api calls, initialization, and cleanups(release resources like event listeners). 1) mounting - when a component is first is injected into the DOM and rendered for the first time 2) unmounting - when a component is removed from the DOM and is no longer being rendered 3) Updating - when a state inside the component changes or prop is passed into the component The useEffect hook is useful and can run in all of these different lifecycles. import { useEffect } from 'react' The basic syntax takes in a callback function: useEffect (() => {   //code }) this will run everytime a component mounts or updates. In order to run only when the component mounts:

Styled Components

 What I learned today: Styled-components provide several advantages, particularly in component-based web development To get started install the 'styled-components' package. Then you can optionally create a directory to contain all of your styled components Then you can define it like this for example: const Wrapper = styled . div `   position : relative ;   .logout-btn {     display : flex ;     align-items : center ;     justify-content : center ;     gap : 0 0.5rem ;   }   .img {     width : 25px ;     height : 25px ;     border-radius : 50% ;   } And then you can apply your CSS by simply wrapping it around your React components.   return (     < Wrapper >         < button type = 'button' className = "btn logout-btn" />       </ Wrapper >   ) Some advantages of styled components: Scoped Styling : Styles are scoped to specific components, ensuring they don't leak into other parts of the application. This prevents style conflict

e-commerce website built with React.nodejs

            This is a responsive e-commerce website I built with React and Nodejs. Users can browse, add goods to the cart, and checkout with a valid credit card number Live Demo    (you can use this test credit card #: 4242 4242 4242 4242)            Repo frontend           Repo backend                 First things first - creating a landing page        I wanted to spend some time making the marketing page look good because I felt like an ecommerce site should look as attractive as possible. Styling was done with vanilla css. I made sure this site was responsive using media queries.       Creating the backend   I didn't think I would need my own backend for this project but I couldn't find an API that fit the type of products I wanted to "sell". So I created my own. Two notable features I used are: JWT authentication and Stripe (to process the payment by customers). The backend is set up  so that users can login or checkout as guests and it will handle the payments
