React Hooks are a new addition in React 16.8 that let you use state and other React features without writing a class. In this guide, we'll cover useState, useEffect, useContext and more with practical examples.

The useState hook is the most basic hook that allows you to add state to functional components. It returns a stateful value and a function to update it.

The useEffect hook lets you perform side effects in function components. It serves the same purpose as componentDidMount, componentDidUpdate, and componentWillUnmount in React classes, but unified into a single API.

The useContext hook accepts a context object (the value returned from React.createContext) and returns the current context value for that context. When the nearest context provider updates, this hook will trigger a rerender with the latest context value.

In this tutorial, we'll build a simple application that demonstrates how to use these hooks effectively in your React projects.

I've been trying to optimize my workflow lately and I'm curious what productivity tools other developers are using. I'm currently using Notion for notes and project management, but I'm looking for something that integrates better with my coding workflow.

Some tools I've tried:

• Notion - Great for documentation but lacks some developer-specific features
• VS Code with extensions - Good for coding but not ideal for general task management
• Trello - Nice for kanban boards but feels disconnected from my code
• GitHub Projects - Decent integration with code but UI could be better

What tools are you using to stay productive? Any recommendations for something that bridges the gap between coding and project management?

With the increasing number of data breaches, API security has become more important than ever. In this post, I'll share some best practices for securing your APIs based on my experience working as a security engineer.

1. Use proper authentication

Always implement strong authentication mechanisms like OAuth 2.0 or JWT. Never rely on API keys alone for sensitive operations.

2. Implement rate limiting

Protect your APIs from abuse and DDoS attacks by implementing rate limiting. This helps ensure availability and prevents brute force attacks.

3. Validate all input

Never trust client input. Validate all parameters, headers, and request bodies to prevent injection attacks.

4. Use HTTPS everywhere

Always use HTTPS to encrypt data in transit. There's no excuse for not using TLS in 2023.

5. Implement proper error handling

Don't leak sensitive information in error messages. Use generic error messages for clients while logging detailed errors server-side.

What other security practices do you follow for your APIs? Let me know in the comments!
