Benefits of taking our course
Functional Tools
1 - Visual Studio Code (VS Code)
VS Code is a powerful code editor that provides an extensive development environment for React Native applications. Its rich ecosystem of plugins and extensions enhances debugging capabilities, making it a preferred choice among developers. With features like intelligent code completion, syntax highlighting, and integrated terminal, students will learn how to navigate and utilize these tools effectively for enhanced productivity. The editor's seamless integration with version control systems like Git further empowers developers to manage code versions effortlessly while debugging.
2) React Developer Tools
This essential extension allows developers to inspect and debug React component hierarchies in their applications. The React Developer Tools enable students to examine component states and props, providing insights into how data flows through the application. Students will learn to identify rendering issues and track performance bottlenecks by utilizing this tool during their debugging sessions, enhancing their ability to write optimized and bug free code.
3) Flipper
Flipper is a debugging tool specifically designed for mobile apps, including those built with React Native. It provides a platform to inspect network requests, view logs, and manage database data easily. In this training program, students will explore how to use Flipper to monitor their apps in real time, troubleshoot performance issues, and access various plugins that can aid in debugging. Flipper’s functionality allows developers to gain deeper insights into their app's behavior on both Android and iOS platforms.
4) Debugger for Chrome
Integrating the Chrome debugger with VS Code offers students a comprehensive debugging experience directly within their code editor. By setting breakpoints and stepping through code, learners can analyze the execution of their applications line by line. This powerful tool will help students investigate variable states, function calls, and error messages, all of which contribute to resolving issues effectively. Moreover, developers can utilize the DevTools console for logging and inspecting values, crucial for understanding code flow.
5) Console.log()
While a straightforward debugging tool, the console.log() statement is integral to the debugging process. It allows developers to print variable values and application states to the console, facilitating a better understanding of behavior at various execution stages. In this course, students will learn best practices for using console.log() effectively and how to strategically place log statements to trace the flow of their applications. Understanding when and where to implement these logs enhances their debugging strategies.
6) Error Boundaries
Error boundaries are a React feature that allows developers to catch JavaScript errors in their component tree and display a fallback UI instead of crashing the application. Through this training, students will explore how to implement error boundaries in their React Native applications, ensuring that unhandled errors are captured gracefully. By learning to define error boundaries, participants will improve the robustness of their applications, making error management an integral part of the debugging process, ensuring a better user experience.
7) Simulator and Emulator Debugging
Simulators and emulators are critical tools for debugging React Native applications. Students will learn how to deploy their apps on both iOS and Android simulators/emulators, which replicate mobile device environments.

Integrating error logging services such as Sentry or Rollbar allows developers to track and report errors in production environments effectively. Students will learn how to set up and configure these services to automatically log exceptions and capture context about the errors. By analyzing error reports from users, learners can identify patterns, prioritize issues, and improve their application’s resilience over time.
12) Performance Monitoring Tools
Tools such as React Native Performance and Metro Bundler’s performance monitor provide insights into app performance metrics. Students will explore how to measure their application's performance by identifying slow components, unoptimized render cycles, and excessive re renders. This knowledge will empower them to optimize their applications, ensuring that users enjoy a smooth and responsive experience.
13) Linting and Code Quality Tools
Integrating linting tools like ESLint can help catch errors and enforce coding standards before they make it to the testing phase. In this course, students will learn how to configure and use linting tools to maintain code quality and consistency. By rectifying potential errors early in the development process, learners will enhance their overall debugging efficiency, focusing on solving real issues rather than formatting mistakes.
14) Code Review Practices
Participating in code review practices fosters collaboration among developers and promotes the sharing of debugging knowledge. Students will learn how to conduct effective code reviews, giving feedback on potential issues, and discussing debugging strategies with peers. These collaborative sessions will enhance their understanding of coding techniques and improve their problem solving skills through diverse perspectives.
15) Documentation and Comments
Effective documentation and comment practices can significantly aid debugging. In this training, students will learn the importance of writing clear comments, maintaining comprehensive documentation, and using descriptive variable names. This attention to detail allows other developers (or themselves at a later date) to understand the purpose of the code quickly, making it easier to navigate and debug any issues that arise in the future.
