Benefits of taking our course
Functional Tools
1 - React Native: This framework is the foundation of the course, allowing developers to build cross platform mobile applications with JavaScript and React. React Native enables smooth animations and a native look and feel across iOS and Android devices. It leverages native components, offering better performance than traditional hybrid frameworks. Students will learn how to set up a React Native environment, create components, manage state, and handle navigation within the app.
2) Expo: Expo is a set of tools and services built around React Native, providing a streamlined process for developing applications. It simplifies tasks such as setting up development environments and deploying applications. With Expo, students can utilize a wide range of APIs for accessing device hardware, like the camera required for scanning QR codes. The course will cover how to use Expo to quickly prototype and test applications on real devices, enhancing the development experience.
3) React Navigation: This library combats the complexity of navigating between different screens in a React Native application. React Navigation provides versatile navigation patterns essential for user experience, including stack, tab, and drawer navigation. In this course, students will explore how to implement navigation, manage navigation state, and pass data between screens, which are critical skills for developing a seamless app.
4) React Native Camera: This plugin enables access to the device’s camera, which is crucial for the QR code scanning functionality. Students will learn how to integrate the camera, manage permissions, and handle real time camera feeds. The course will detail how to set up the camera component for optimal scanning performance, ensuring the app can reliably read QR codes from various angles and lighting conditions.
5) QRCode.js: This JavaScript library helps students generate QR codes within the app. QRCode.js allows for customization of QR codes, including size and color options. Through this course, learners will understand how to use this library to create unique codes that can be scanned, making the application more functional and versatile for end users.
6) Redux (optional): Redux is a state management library that can be used to manage the application's global state efficiently. While not mandatory for the QR code scanner app, understanding Redux can provide students with an insight into maintaining complex state management across various components, especially as the application scales. The course will touch upon when and how to implement Redux for effective application architecture, preparing students for future projects that may require advanced state management solutions.
7) Jest and Testing Library: These tools will introduce students to testing their applications to ensure code quality and performance. Jest is a popular testing framework for JavaScript applications, while React Native Testing Library provides utilities for testing React components.
