React Native Firebird Driver

This package uses the node-firebird-driver interfaces and provides its own JSI/native implementation. It requires a bare React Native app or a development-client app using the New Architecture; it does not support iOS or Expo Go in this version.

Experiments

Electric Firebird

Electric Firebird (mariuz/electric-firebird on GitHub) compiles the Firebird database engine to WebAssembly, following the same approach PGlite used for PostgreSQL. The goal is to let Firebird run both server-side (in Node.js) and fully client-side in the browser, with no server round-trip needed for queries.

FBSimCity

FBSimCity is an explorable isometric city where every building represents a real Firebird subsystem, and every glowing particle represents a query traveling through the system — in through the client harbor, through the SQL translator, into the relational engine, and back home carrying results.

• Live: https://mariuz.github.io/FBSimCity/

• Source: https://github.com/mariuz/FBSimCity (MIT license, plain HTML/JS, no build step)

Purpose of the FBSimCity project
It is aimed at engineers who know SQL but have never seen what happens underneath it (i.e., “under the hood”).
Please note: this is a model, not an emulator. No SQL is actually parsed, and no Firebird code runs in the browser.

We are happy to announce the release of Jaybird 6.0.6 and Jaybird 5.0.13, providing bug fixes. Jaybird is the Firebird JDBC driver.
