FB4D: A Cross-Platform Open Source Firebase Library for Delphi

FB4D empowers Delphi developers to seamlessly integrate Google Firebase services into their applications built with either the cross-platform Firemonkey (FMX) or Windows (VCL) framework.

This versatile library offers comprehensive support for:

• Firebase Realtime Database: Enable real-time data synchronization and offline capabilities.
• Firestore Database: Leverage a scalable NoSQL database for application data.
• Firebase Authentication: Supports email/password and anonymous authentication methods.
• Firebase Storage: Securely store and manage user-generated content like images and videos.
• Firebase Functions: Execute server-side code without managing infrastructure.
• Gemini AI: Integrate natural language processing combined with image and document interpretation capabilities.
• Vision ML: Integrate machine learning image processing capabilities.

Built upon the Firebase REST API, the library provides both synchronous and asynchronous methods, making it ideal for GUI applications, services, and background threads. As a pure source code library with a fluent interface design, FB4D ensures clean and concise code integration for your Delphi projects.

The wiki helps with familiarization as well as product maintenance

This project provides a well-structured wiki for easy learning.

Seven cross platform example applications based on Firemonkey (Samples/FB4D Samples.groupproj) and three VCL sample applications (Samples/FB4D Samples VCL.groupproj).

A comprehensible Getting-Started on the wiki will help you to start working with the library. For more detailed questions, the interface reference will provide the answers you need.

You can also find educational videos on our YouTube channel.

Prerequisites

The sample projects are developed and prepared for Delphi 12.2 Athens. The library requires at least Delphi 10.3 Rio Update 2.

Hint: Support from Delphi 10 Seattle to Delphi 10.2 Tokyo has been discontinued since the introduction of the Firestore Listener in March 2021. Delphi 10.3 Update 1 and earlier version are not longer supported because of an issue in the RTL.

Delphi is a registered trademark of Embarcadero Technologies, Inc.

Supported Platforms

FB4D is developed in pure object pascal and can be used with Firemonkey on all supported plattforms. The library and its sample projects are currently tested with Win64/Win32, Mac64/32, Linux64 by using FMXLinux, iOS64 and Android.
Hint to mobile platforms: The TokenJWT to perform the token verifcation requires the installation of the OpenSSL libraries. For more information about using OpenSSL see the installation of OpenSSL.

Submodules

For authorization token verification and token content extraction this library uses the Delphi JOSE JWT library. Thank you Paolo Rossi for your great library! github.com/paolo-rossi/delphi-jose-jwt
