Timeout 2023: Implementing App Timeout in React

2023 has been a year of professional growth and experiences for the writer, leading to improved technical and writing skills.
The article presents a method to implement timeout functionality for a React app by creating a provider and wrapping the app with it.
Prerequisites include a good understanding of Javascript, React, and Vite.
Timeout functionality is crucial for apps handling sensitive user data or financial transactions to monitor inactivity and enhance security and privacy.
Key advantages of having timeout include security enhancement, resource management, and compliance with security standards.
The implementation involves creating a TimeoutProvider component that triggers actions after a set period of user inactivity.
Events like mousemove, keydown, click, and scroll are monitored to determine user activity and trigger the timeout logic.
The code example involves using useEffect, event listeners, exempted routes, navigation, and cleanup functions to manage the timeout feature.
The router setup, creation of Home and NextYear components, and integration of the TimeoutProvider in the App component ensure the timeout functionality is applied across the app.
The article concludes with a playful mention of the 'timeout' concept in 2023, inviting readers to share alternative approaches and looking forward to an exciting 2024.

Cracking JavaScript: My Notes from LeetCode’s 30-Day Challenge

The article compiles notes from working on LeetCode's 30 Days of JavaScript exercises, covering fundamental JavaScript concepts like closures, data encapsulation, immutability, high-order functions, function composition, and recursion.
JavaScript closures allow functions to retain access to their lexical scope, even when executed in a different scope, providing benefits such as data encapsulation and avoiding global variables.
The performance difference between the forEach method and the for loop lies in abstraction and readability versus direct access to array elements. forEach offers cleaner code but with a performance cost due to callback invocation.
Functional programming concepts like pure functions, immutability, high-order functions, function composition, and declarative programming are explained, showcasing best practices and examples for each.
Memoization, using caching to store function results for performance improvement, is discussed. An example with a memoized Fibonacci function demonstrates the efficiency gained through this technique.
Promises in JavaScript, including Promise.all() to handle multiple promises concurrently, common interview questions on setTimeout and clearTimeout, and the Event Loop and Task Queue mechanisms, are explained to deepen understanding of asynchronous operations.
Debounce, a technique to limit function executions and optimize performance, is explored along with its common use cases and implementation.
The article aims to provide a comprehensive understanding of JavaScript concepts through practical examples, making it a valuable resource for interview preparation and enhancing JavaScript skills.

5 common assumptions in load testing—and why you should rethink them

The article highlights five common misconceptions in load testing that can mislead teams and hinder performance optimization.
Testing directly on production may seem logical for accurate results, but the risks of potential operational issues and downtime make creating a staging environment a safer approach.
Relying solely on feature-rich load testing tools without understanding user behavior and integrating tests into the development process can lead to missed performance issues.
Treating load testing as a time-consuming formality before release can delay product launches and impact competitiveness, emphasizing the importance of efficient testing integration.
Upgrading infrastructure to handle increased users may not address the root cause of performance issues, such as inefficient code or unexpected user behaviors.
The debate between open-source and commercial load testing tools highlights the need to choose tools based on scalability, support, and project requirements rather than solely on cost.
The article concludes by emphasizing the importance of purposeful load testing, user understanding, and seamless integration into development workflows to optimize performance effectively.

Code Faster in Cursor: A Pragmatic Guide to Voice Prompting

Typing detailed prompts manually can be slow due to the keyboard bottleneck.
The solution is to use Whisper to dictate prompts directly into Cursor, which is around 5 times faster than typing.
The biggest mistake in AI-assisted programming is the lack of information in the prompt.
Using dictation with AI tools like Cursor can lead to more detailed and useful prompts, resulting in better results.

Getting Started with Angular Signals: A Beginner’s Guide Part 1

Angular Signals are a new reactive primitive in Angular that simplify state management and offer direct access to updated values.
There are two types of signals: Writable Signals (for updating values) and Computed Signals (derive value from other signals).
A simple counter example demonstrates the usage of a writable signal in Angular.
Benefits of using signals include simplicity, performance improvement, and reduced boilerplate code.
To set up an Angular environment for using signals, ensure you have Angular 16+ installed.
Signals can be implemented in components using writable signals for direct state updates.
Computed signals allow deriving values based on other signals, providing enhanced functionality.
Best practices for signals include avoiding direct mutations and handling computed signals carefully.
If transitioning from RxJS, use Angular's toSignal and toObservable utilities gradually to mix signals with observables.
Angular Signals offer a simple yet powerful way to handle state and reactivity in Angular applications, improving development experience.

Declarative Schemas for Simpler Database Management

Declarative schemas have been introduced to simplify managing and maintaining complex database schemas by defining the database structure in .sql files.
Benefits of declarative schemas include maintaining the entire database schema in one place, generating migration files automatically, and facilitating concise code reviews.
Declarative schemas provide a single point of reference compared to using versioned migrations, especially for complex and frequently-updated database schemas.
The complexity of database schemas can slow down development velocity, as changes may affect other views or functions, requiring multiple steps and manual updates.
Using declarative schemas in production streamlines the process by allowing changes to be made in one place, reducing the need to duplicate changes across multiple files.
A schema diff tool like migra can be used to identify necessary updates for views and functions when generating migration files, simplifying the development process.
Declarative schemas on Supabase provide tools for managing database schemas in one place, simplifying the development process and reducing the time spent on managing migrations.
Declarative schemas improve development efficiency by enabling engineers to make schema changes in a centralized manner, cutting down development time significantly.
Supabase CLI now includes the tools used internally for managing migrations, offering developers a streamlined experience when working with database schemas.
Declarative schemas offer a more efficient way to manage database schemas, providing benefits such as simplified development processes and easier merge conflict resolutions.
