React frontend migration in Frankfurt and across Germany
Gateflow is an IT company in Frankfurt that migrates existing web interfaces to React. Companies in the Rhine-Main region and across Germany can commission a defined part of an application or a sequence of releases. The starting point is the functionality your team needs to retain and the development work the new frontend should support.
React migration planning in Frankfurt and Rhine-Main
Gateflow examines the existing frontend with the people responsible for the application. The review establishes which screens share business rules, which interfaces already exist and where a separate React area can run. The Gateflow company profile explains the wider service offering. Meetings in Frankfurt and the Rhine-Main region can be arranged around architecture decisions and acceptance.
Frontend migration assessment and scope
A migration needs an inventory of routes and behaviors before code moves. Gateflow records entry points, user permissions and dependencies on the current frontend. Your team identifies the functions that must remain available during the transition. The resulting scope separates required behavior from requested redesigns, so the migration estimate does not silently include a different product.
React component migration with existing business rules
Gateflow transfers the selected interface functions into React components, including validation messages and loading states. Existing business rules remain explicit: a visual redesign does not authorize a change to prices, permissions or submission logic. The broader business application development service covers additional functionality when needed. Each transferred area receives acceptance criteria that describe what users must be able to complete.
Incremental React migration across application routes
React can be introduced into a selected page area or a separate route while the surrounding application continues to use its existing technology. Gateflow defines the boundary and checks navigation between both parts. Shared styles and event handlers need particular attention where old and new code occupy the same page. A first release tests that boundary before more screens move.
React API integration and session continuity
A replacement interface must use the correct data and session behavior. Gateflow checks request formats, authorization responses and what happens when a session expires during editing. The work also defines ownership of temporary form data when users move between migrated and retained routes. Backend changes are recorded separately, with an agreed responsibility for reviewing the interface contract.
React migration testing before each release
Gateflow compares the migrated functions with agreed acceptance cases using representative test data. Checks cover successful submissions and the failure states that need a visible response. Website implementation provides the wider context for public pages, including stable addresses and readable content. Your team reviews each completed migration stage before the next group of routes is scheduled.
React migration delivery across Germany
For projects across Germany, Gateflow can work in the existing repository and review process through agreed remote access. Release planning names the person who approves deployment and the conditions for returning to the previous frontend. The plan also addresses changes made to the old application during migration, so parallel development does not leave transferred functions behind.
React migration handover and remaining work
You will receive the transferred source code with build instructions and a record of migrated routes. The handover distinguishes completed work from retained legacy areas and unresolved dependencies. The project delivery process sets out review and acceptance. Your developers can then continue from a documented boundary, or commission Gateflow to migrate the next agreed part of the application.
Discuss your React frontend migration
Gateflow transfers the agreed frontend functions to React and tests the connections to the retained application. You will receive the migrated code, build instructions and a record of tested routes.
