Features

• Binary Serialization Formats - Decodes binary Protocol Buffers data back into structured message instances with control over unknown fields.
• Protocol Buffers - Implements the Protocol Buffers binary serialization mechanism for JavaScript and TypeScript environments.
• Binary Serialization - Provides high-performance conversion of JavaScript objects into compact Protocol Buffers binary formats.
• Cross-Language Data Protocols - Enables consistent data exchange between JavaScript and other languages using standardized Protocol Buffers schemas.
• Length-Delimited Encodings - Encodes message instances into binary format, including support for length-delimited encoding for streaming.
• JSON-Protobuf Mapping - Provides bidirectional mapping between structured Protocol Buffers messages and JSON strings or objects for API interoperability.
• Reflection-Based Object Models - Parses schema files into an internal tree of objects that drives runtime encoding and decoding.
• Dynamic Type Modeling - Dynamically generates JavaScript classes and constructors at runtime based on parsed Protocol Buffers schema definitions.
• Protobuf Descriptor Loading - Implements a dynamic parser that processes .proto files to build in-memory service maps at runtime.
• Code Generators - Produces static JavaScript modules and TypeScript declarations from schemas to eliminate runtime reflection overhead.
• Object-to-Data Mapping Frameworks - Creates formal message instances from plain JavaScript objects to ensure data conforms to the defined schema.
• Data Schema Validation - Verifies that plain JavaScript objects conform to a schema by checking required fields and type definitions.
• Object Mapping Frameworks - Transforms formal message instances into plain JavaScript objects with configurable options for enums and bytes.
• Schema Validation - Verifies that data objects conform to a schema by validating required fields and enumeration values.
• Dynamic Schema Parsing - Allows loading and processing of Protocol Buffers schemas at runtime to handle data dynamically.
• Programmatic Definitions - Constructs types and namespaces dynamically using a reflection API instead of loading external files.
• Reflection Bundles - Serializes internal schema models into compact JSON files to accelerate loading in production environments.
• Definition Loading - Imports service descriptors via reflection, source files, or binary sets to define message structures.
• Reflection Bundle Generation - Creates JSON bundles and declaration files to enable the dynamic loading of message types at runtime.
• Static Type Generators - Generates TypeScript declarations and JavaScript modules from schemas to reduce runtime overhead.
• Schema Parsing - Converts .proto source files into a reflection-based object model while preserving comments and custom options.
• Protocol-Agnostic Transport Layers - Maps service definitions to a generic request-response interface, allowing for any underlying communication layer.
• RPC Frameworks - Provides a framework for implementing transport-agnostic RPC clients based on service definitions.
• Service Metadata Management - Enables the implementation of service definitions and the exposure of metadata to facilitate remote procedure calls.
• Compile-Time Code Generation - Provides a compiler plugin to automate the generation of JavaScript and TypeScript files during the build process.
• Data Validation Schemas - Verifies that JavaScript objects conform to required fields and type definitions specified in the schema.
• Zero-Allocation Buffer Encoders - Implements serialization that writes encoded data directly into pre-allocated buffers to minimize garbage collection overhead.
• gRPC Service Implementations - Provides a framework for implementing and consuming RPC services using Protocol Buffers definitions.
• Data Serialization - Protocol Buffers implementation for JavaScript.
• Serialization Tools - Protocol Buffers implementation for JavaScript.
