Top Laravel Security Best Practices: How to Secure Your Web Application 🚀 Laravel is one of the most popular PHP frameworks for web application development, known for its elegant syntax and robust features. However, security is a critical concern when building applications that handle sensitive data. This guide outlines essential security best practices to protect your Laravel application from vulnerabilities such as SQL injection, XSS, CSRF, and other threats. 1. Authentication & Authorization Laravel provides built-in authentication systems that make user authentication easy and secure. Use Laravel Breeze or Jetstream for authentication instead of building it from scratch. Implement Role-Based Access Control (RBAC) to manage permissions effectively. Enforce Multi-Factor Authentication (MFA) where necessary to add an extra layer of security. 2. Prevent SQL Injection SQL injection is a serious threat, but Laravel’s Eloquent ORM and Query Builder help prevent it...
`useCallback` is a useful hook for optimizing performance in React applications by preventing unnecessary re-creations of functions. However, you should use it wisely, as it can add complexity and may not always offer a performance improvement in every case. ### 1. **What does `useCallback` do?** `useCallback` returns a memoized version of the callback function that only changes if one of the dependencies has changed. It’s primarily used when passing a function as a prop to child components or using it in an effect (like `useEffect`), where unnecessary re-creations of the function can lead to performance problems. ### 2. **Syntax:** ```javascript const memoizedCallback = useCallback(() => { // Your callback code }, [dependencies]); ``` - The first argument is the function you want to memoize. - The second argument is an array of dependencies (like `useEffect`). The function will only be re-created if any of these dependencies change. ### 3. **When to use `useCallback`?** You s...
To pass the assigned_users array from a child component to its parent component, you need to follow these steps: Create a callback function in the parent component : This function will be responsible for receiving the assigned_users array. Pass the callback function to the child component as a prop : The child component can then call this function when it wants to send the assigned_users array to the parent. Call the callback function from the child component : Inside the child component, when you want to send the data to the parent (e.g., after updating assigned_users ), you call the callback function with the updated array. Parent Component jsx Copy code import React , { useState } from 'react' ; import ChildComponent from './ChildComponent' ; const ParentComponent = ( ) => { const [assignedUsers, setAssignedUsers] = useState ([]); // Callback function to update the parent state const handleAssignedUsersChange = ( users ) => { setAssig...
