Capturing Live User Input with JavaScript Input Events

Real-time input feedback relies on browsers and scripts understanding when to trigger and react to input events effectively.
The input event reacts instantly to every small change in a field's value, perfect for reflecting changes immediately.
In contrast, the change event triggers only when the field loses focus and its value has changed, waiting for user commitment.
Browsers queue input events in the main thread, allowing multiple listeners to fire consecutively with the already updated field value.
Different input types, like text fields, sliders, checkboxes, and dropdowns, trigger input and change events in varying patterns.
Managing a stream of input events can lead to performance issues, which can be addressed using throttling and debouncing patterns to control the frequency of function execution.
Throttling limits how often a function runs by responding at fixed time intervals, preventing overwhelming browser or server operations.
Debouncing waits for a pause in input before executing the function, ideal for scenarios where response after the user finishes typing is desired.
Throttling provides frequent updates while input is ongoing, while debounce ensures a single callback after a period of inactivity.
Understanding and implementing throttling and debouncing appropriately can enhance user experience by managing input event handling effectively.

Golden ratio base numbers

Positive integers can be expressed as a sum of powers of the golden ratio (φ) using a binary-like number system called phinary.
This system allows coefficients of 0 and 1 in front of each power of φ and includes negative powers of φ to represent positive integers.
Phinary representations are not unique, but by enforcing the rule of non-consecutive 1s, unique representations can be achieved, similar to the Fibonacci number system.
The phinary system was discovered by George Bergman at the age of 12 and has since seen more sophisticated developments in mathematics.

DynamoDB with Enhanced Client - Schemas and data serialization made easy

DynamoDB, a NoSQL Database offered by AWS, provides flexible schema, but controlling schema is important to avoid chaos.
The AWS SDK-v2 for Java includes an EnhancedClient API for strict table schema setup and data serialization.
The article discusses setting up the EnhancedClient API for DynamoDB local using a Spring Boot project.
Endpoints like POST /api/v1/book, GET /api/v1/book/id, GET /api/v1/books, and GET /api/v1/books/year/{year_published} are implemented.
A document structure for the Books table includes fields like id, author, genres, yearPublished, and more.
Codes for setting up the EnhancedClient, Bean, and TableSchema in Java are provided for handling schema and data serialization.
The EnhancedClient API allows fine control over the schema and robust data handling in DynamoDB.
A service class BookService is created to power the APIs for operations like adding a book, fetching all books, and querying books by year published.
The article showcases how EnhancedClient API simplifies data serialization and schema definition, ensuring consistency and ease of development.
The controller in the application handles requests by delegating them to the service layer, demonstrating a clean architecture setup.

Add Dark theme & Light theme in website

Enabling dark mode and light mode on a website involves creating a user interface that allows users to switch between two different color schemes: light mode with lighter backgrounds and dark mode with darker backgrounds.
Implementing dark mode on websites can enhance user experience and make the website more accessible in different lighting conditions.
Different ways to enable dark mode on websites include using color-scheme CSS property, prefers-color-scheme media query, color-scheme meta tag, setting color-scheme value in meta tag using JavaScript, setting attributes in the body tag, and setting class name in html tag using JavaScript.
The color-scheme CSS property allows selection of color themes like normal, light, dark, or both light and dark based on the user's operating system theme selection.
prefers-color-scheme media query lets you customize CSS layouts based on user's OS theme preferences like no-preference, dark, or light.
Using a meta tag like enables switching between dark and light modes based on user's OS theme selection.
Setting color-scheme value in meta tag using JavaScript allows dynamic switching between dark and light modes in a website.
Enabling dark mode by setting attributes or class names in the body or html tags dynamically using JavaScript offers a more interactive user experience.
By allowing users to toggle between light and dark modes, websites can provide a personalized browsing experience, ensuring accessibility and visual appeal.
Implementing theme toggle modes using CSS and JavaScript provides flexibility in catering to user preferences for viewing content in their preferred mode.

Building Reliable Protected Routes with React Router v7

Protected Routes in React Router v7 are used to restrict access to private pages, similar to a bouncer at a VIP area of a nightclub.
The AuthContext is set up using React's Context API to track user authentication status, loading state, user role, and login/logout functions.
A PrivateRoute component acts as a 'digital bouncer' by checking authentication status, displaying a loader during verification, and rendering protected content or redirecting to /login.
Private pages are grouped under }>, allowing easy encapsulation and control over access.
Lazy loading is implemented to improve performance, loading private pages only when requested by users.
For role-based access control, PrivateRoute can be extended with allowedRoles prop to restrict access based on user roles.
The approach centralizes authentication logic, provides clear analogies for understanding, improves performance with lazy loading, and offers flexibility for customizations.
