🎥 Welcome to Our YouTube tutorial: Setting Up Expo React Native App With testing and Typescript📱🚀
Показать описание
In this video, we'll walk you through the step-by-step process of setting up a new Expo React Native app with Jest and TypeScript. By the end of this tutorial, you'll have a fully configured project ready for development.
🔧 Here's what you'll learn:
Step 1: Install Expo CLI
- We'll start by installing Expo CLI, the command-line tool for creating and managing Expo projects.
Step 2: Create a new Expo project
- Using the Expo CLI, we'll create a new Expo project with the "blank" template and TypeScript as the language.
Step 3: Install dependencies
- We'll install the necessary dependencies for our project, including @testing-library/react-native for testing.
Step 5: Install additional TypeScript dependencies
- We'll install additional TypeScript dependencies to ensure proper type checking and compatibility.
Step 6: Install Jest dependencies
- We'll install Jest and related dependencies for testing our React Native components.
- We'll create a mock file to handle file imports in our tests.
Step 10: Create a sample test file
- We'll create a sample test file to demonstrate testing with @testing-library/react-native.
Step 11: Run the app
- Finally, we'll start the app using the "npm start" command and verify that it's running correctly.
🚦 Troubleshooting Errors:
Throughout the tutorial, we'll address common errors you may encounter and provide solutions to help you overcome them. Some of the errors we'll cover include:
- Validation Error: Preset jest-expo not found
- Validation Error: Module @testing-library/jest-native/extend-expect not found
By the end of this video, you'll have a fully set up Expo React Native app with testing capabilities. Let's dive in and get started!
