We are excited to announce the launch of firestoreproto2json on February 29, 2024. This Java library is designed to bridge the gap between Firestore’s efficient internal storage and the developer-friendly world of JSON.

Core Capabilities

firestoreproto2json provides a robust mechanism to transform Firestore Protocol Buffer representations of documents into standard JSON objects. Key features include:

  • Seamless Event Handling: Full support for DocumentEventData objects, making it an ideal companion for developers building Google Cloud Functions.
  • Comprehensive Type Mapping: Automated conversion of all primary Firestore data types—including Arrays, Maps, Geopoints, and Timestamps—into their JSON equivalents.
  • Flexible Input Options: Built-in helpers to handle both binary and base64 encoded protobuf inputs.
  • Granular Control: The ability to convert current and previous document values independently.

Why it Matters

While Firestore’s use of protocol buffers is excellent for performance and storage, these binary formats can be cumbersome to work with directly in application code. Developers often find themselves wrestling with complex protobuf structures when processing events in the cloud, which can slow down development and introduce bugs.

By providing a predictable and easy-to-use conversion to JSON, firestoreproto2json removes this friction. It allows developers to treat Firestore data as simple JSON objects, enabling them to focus on their core business logic rather than the intricacies of protobuf parsing.

Getting Started

firestoreproto2json is available as a Maven dependency for projects using Java 17. To add it to your project, include the following in your pom.xml:

<dependency>
    <groupId>com.unitvectory</groupId>
    <artifactId>firestoreproto2json</artifactId>
    <version>0.0.1</version>
</dependency>

As this is an early candidate release, we encourage you to explore the library and provide feedback to help us shape the journey toward a stable 1.0 version.
