## Continuous Integration (CI)

- **Type Checking**: Ensure all TypeScript code passes type checking before proceeding.
  - Run `tsc --noEmit` to perform type checking without generating output files.

- **Linting and Code Formatting**: Maintain code quality and consistency.
  - Integrate ESLint with TypeScript support.
  - Use Prettier for code formatting.
  - Configure CI to fail on linting or formatting errors.

- **Unit Testing**: Verify individual components function correctly.
  - Use Jest with `ts-jest` preset.
  - Ensure tests cover critical paths and edge cases.
  - Configure CI to run tests and fail on test errors.

- **Build Process**: Compile TypeScript code to JavaScript.
  - Use `tsc` or a bundler like Webpack.
  - Generate source maps for debugging.
  - Ensure build artifacts are versioned and stored centrally.

## Continuous Deployment (CD)

- **Containerization**: Package the application and its dependencies.
  - Use Docker to create a container image.
  - Ensure the image is environment-agnostic.
  - Store images in a secure registry.

- **Automated Deployment**: Deploy the application to target environments.
  - Use deployment scripts or tools like Kubernetes.
  - Ensure deployments are repeatable and consistent.
  - Implement rollback mechanisms for failed deployments.

- **Security Practices**: Protect the application and data.
  - Integrate automated security tests into the pipeline.
  - Manage secrets securely, avoiding hardcoding.
  - Regularly audit dependencies for vulnerabilities.

- **Monitoring and Logging**: Track application performance and health.
  - Implement logging for all critical operations.
  - Set up monitoring tools to detect issues promptly.
  - Ensure logs are centralized and accessible for analysis.
