Develop React Native Apps Like a Pro
Article Summary
Mike Chudziak tackles a problem every React Native team faces: codebases that work but don't scale. His 2017 guide remains surprisingly relevant for teams struggling with code quality as projects grow.
Drawing from experience reviewing codebases worldwide, Chudziak outlines five essential tools that transform React Native development from functional to professional. The article focuses on practical setup for teams moving beyond prototype stage.
Key Takeaways
- ESLint with Airbnb config enforces consistent React code standards across teams
- Prettier auto-formats code, eliminating style debates when hooked to pre-commit
- Flow adds static typing to catch errors and improve code readability
- Haul (now Re.Pack) replaces default packager, enabling webpack aliases and symlinks
- Jest snapshot testing covers significant code with minimal test writing effort
Five developer tools (ESLint, Prettier, Flow, Haul, Jest) form the foundation for maintainable React Native apps that scale with team size and complexity.
About This Article
A lot of JavaScript developers skip over code quality, tests, and type checking. They treat these as nice-to-haves, even though they matter a lot when you're working with a team or building something that needs to scale.
Chudziak suggests using ESLint with airbnb configuration, Prettier to format code automatically, Flow for static typing, Haul to access the webpack ecosystem with directory aliases, and Jest for snapshot testing. Together these tools help enforce consistent standards.
With these five tools in place, teams can use aliases instead of relative import paths, get consistent code formatting without manual work, catch type errors before they become problems, and build solid test coverage using Jest snapshot testing without writing a ton of test code.
