Codeigniter 17: Debugging Common Issues in CodeIgniter REST APIs Building and maintaining a REST API can sometimes involve unexpected challenges. Identifying and resolving common issues in CodeIgniter APIs ensures the application remains robust and reliable. This guide covers debugging techniques and solutions for frequent problems.   Common Issues in CodeIgniter REST APIs  Incorrect Routes or Endpoints: Symptoms: Receiving 404 errors when accessing an endpoint. Solution: Ensure your routes are correctly defined in app/Config/Routes.php: $routes->get('users', 'UserController::index'); Verify that controllers and methods exist and match the route. CORS Errors: Symptoms: Front-end applications cannot access the API due to cross-origin issues. Solution: Enable

Codeigniter 16: Integrating a CodeIgniter REST API with Front-End Frameworks (e.g., React or Angular) Integrating a REST API with modern front-end frameworks such as React or Angular is a common requirement for building dynamic, data-driven web applications. In this guide, we’ll walk through how to connect a CodeIgniter REST API with React or Angular.   Why Integrate Front-End Frameworks with a REST API?   Dynamic User Interfaces: Front-end frameworks enable responsive and interactive user experiences. Separation of Concerns: Decouple the front end from the back end for better scalability. Reusability: APIs can serve multiple platforms, including web and mobile applications.  

Codeigniter 15: Deploying a CodeIgniter REST API on Cloud Platforms Deploying your CodeIgniter REST API on a cloud platform ensures it is accessible, scalable, and secure for production use. This guide will walk you through deploying your API on popular cloud platforms such as AWS, Google Cloud, and Heroku.   Step 1: Prepare Your Application for Deployment  Set the Environment to Production: Update the environment variable in app/Config/Constants.php: define('CI_ENVIRONMENT', 'production'); Enable Debugging (Optional for Production): Ensure detailed errors are disabled by setting: public $log = true; Update Base URL: Set the correct base URL in app/Config/App.php: public $baseURL = 'https://your-domain.com';
