React Native is a powerful framework for building mobile applications using JavaScript and React. With the added benefits of TypeScript, ESLint, and Prettier, your code quality and maintainability can skyrocket. In this guide, we will explore how to set up a React Native project that includes TypeScript, ESLint, Prettier, and integrates CI/CD pipelines using GitLab.

Prerequisites

• Node.js installed on your system
• React Native environment set up (for both iOS and Android)
• Basic understanding of Git and GitLab

Step-by-step Setup

1. Initialize the React Native Project

First, create a new React Native project. Open your terminal and run:

npx react-native init MyNewProject --template react-native-template-typescript

2. Install ESLint and Prettier

To ensure your code is clean and conforms to predefined standards, install ESLint and Prettier:

npm install eslint prettier eslint-config-prettier eslint-plugin-prettier --save-dev

3. Configure ESLint

Create an ESLint configuration file:

npx eslint --init

Follow the prompts to create a configuration that fits your project.

4. Set Up Prettier

In the root directory of your project, create a file named .prettierrc and define your formatting rules. For example:

{
  "semi": true,
  "singleQuote": true
}

5. Configure CI/CD with GitLab

To implement continuous integration and delivery, you’ll need to configure GitLab CI/CD:

• Create a file named .gitlab-ci.yml in your project root.
• Define your job for building the iOS and Android apps:

stages:
  - build

build_ios:
  stage: build
  script:
    - cd ios
    - xcodebuild -scheme MyScheme -sdk iphoneos -configuration Release archive -archivePath $CI_PROJECT_DIR/MyApp.xcarchive

build_android:
  stage: build
  script:
    - cd android
    - ./gradlew assembleRelease

6. Implement Sentry for Error Tracking

Integrate Sentry to track issues in your application:

npm install @sentry/react-native

Follow the Sentry documentation to properly set up and configure it within your app.

Troubleshooting

If you encounter issues during setup or while running your project, consider the following troubleshooting ideas:

• Check the terminal output for any error messages and resolve them accordingly.
• Ensure all dependencies are correctly installed by running npm install.
• If ESLint or Prettier are not working as expected, verify your configuration files for accuracy.
• Look into GitLab CI/CD logs for insights on any build failures.
