Redevelopment of the web front-end in react JS for the new version of the Ficus project. The aim was to improve ergonomics and user experience.

Transitioning to React.js for the front-end of an existing IT project can bring many benefits, but it can also present challenges. Here are some of the potential difficulties you may have encountered when redesigning the front-end in React.js:

Integration with existing code:
Integrating React.js with existing code can be complex, especially if the original project was developed using a completely different language or framework. Adjustments are often necessary to ensure smooth integration.

Data and business logic migration:
If migration is accompanied by significant changes in business logic or data structures, this can lead to challenges. Data migration must be carefully planned and tested to avoid disruption.

State management:
State management in a React application may differ from that of other technologies. Understanding and adopting React’s state management principles, such as the use of the Context API or external state libraries, may be necessary.

Preliminary assessment :
We began by conducting a thorough assessment of the existing application, including an understanding of the business logic, current architecture and technologies in use.

Planning and Strategy:
We developed a detailed migration plan that identified specific milestones, dependencies, potential risks and indicators of success. Make sure this plan is aligned with business objectives.

Interface definition:
We then identified the interfaces between the old and new components, clearly defining how they will interact with each other to ensure smooth integration.

Component reuse:
Wherever possible we identified existing components that can be reused or modified to suit the React environment.

Gradual migration:
We opted for a gradual migration approach rather than redoing everything at once. This involved migrating some parts of the application while leaving others unchanged at the outset.

In-depth testing:
We set up automated tests to ensure that existing functionality was not broken during the migration, and carried out regression tests to detect any potential regression.
