WinDev and migration to other technologies
We maintain and extend applications written in WLangage under WinDev, WebDev and WinDev Mobile, and we migrate them to whichever technology suits their use when the time is right: React and Next.js for a web interface, Java or Rust for processing that has to hold up under load, Symfony or Laravel for business logic already written in PHP, a PostgreSQL database in every case — bearing in mind that many of these applications have been running for ten or fifteen years and carry business rules nobody has documented anywhere but in the code, which makes the takeover more delicate than a mere port of the screens.
Technologies we work with
- WinDev
- WebDev
- WinDev Mobile
- HFSQL
- TypeScript
- React
- Next.js
- PostgreSQL
A migration is not done in one block: we start with a peripheral module, put it into service next to the WinDev application, then move forward module by module, the two systems sharing the same database during the transition; it takes longer than a complete rewrite announced for six months, and it avoids the production outage a failed single cut-over produces.
What we do
WinDev and migration to other technologies
WebDev sites and portals, web services and programming interfaces
WinDev Mobile applications for Android and iOS
Migration from WLangage to React and Next.js, Java, Rust, Symfony or Laravel
Transfer of HFSQL databases to PostgreSQL or SQLite, with integrity checks
Extraction and documentation of the business rules buried in the existing code
Gradual coexistence: the old and the new run side by side for the duration of the switch
