REAL LIFE SCENARIOS

Use Case #1
‍Introduce React Native Features to Native Apps

PROBLEM
Two native app versions (Android and iOS) require separate development efforts.
STEP 1
Develop cross-platform features using React Native.
STEP 2
Integrate these features into both native apps without rewriting the entire codebase.
STEP 3
Share and maintain code seamlessly.
OUTCOME
Reduce duplication of work, streamline teams, and start your journey toward cross-platform efficiency.

Use Case #2
‍Transition to Cross-Platform Apps

PROBLEM
Maintaining two separate native apps is costly and inefficient.
STEP 1
Gradually rewrite components with React Native while retaining some native code.
STEP 2
Merge the apps into a single cross-platform product.
STEP 3
Consolidate your development and maintenance efforts
OUTCOME
Lower costs, unify teams, and simplify your app’s future development roadmap.

FAQ
YOUR QUESTIONS ANSWEReD
Got questions about brownfield migration to React Native? Here’s a quick guide to our process, approach, and how we ensure a smooth and effective transition for your app.
Will React Native match the performance of our existing native code, especially in complex parts of our app?
This is some text inside of a div block.

We know performance is crucial. We keep it on the highest level with techniques like lazy loading and native module optimization, robust monitoring tools, and an incremental migration approach that tests React Native components in real-world scenarios.

Our native teams are already at capacity. How can we transition to React Native without disrupting their workflows?
This is some text inside of a div block.

We prioritize a smooth transition for your native teams through developer-friendly tools, comprehensive training, incremental adoption, and ongoing support tailored to your team’s needs.

How can we minimize the risk of bugs or regressions during the migration process?
This is some text inside of a div block.

We mitigate the risk of regressions with detailed assessments, incremental migration, automated testing, and rollback mechanisms for quick issue resolution.

With tight release cycles, how can we ensure the migration won’t disrupt schedules or delay time-to-market?
This is some text inside of a div block.

Our approach minimizes disruptions by enabling parallel development, gradual integration of React Native, and aligning with your release cycles through close collaboration.

Will the resulting app architecture be scalable and maintainable in the long term?
This is some text inside of a div block.

We ensure scalability and maintainability with modular architecture, reusable components, best practices, and thorough knowledge transfer to empower your team.
