Lightweight DSL for building JSON trees, supporting various types like Map, Array, Collection, and more. Easily convert objects to JSON strings or JS objects with extended serialization options.

Asynchronous Elasticsearch query DSL enabling typed query expressions, sub-field navigation, and declarative query modifications. Supports multiple serialization libraries and autodetects Elasticsearch and Opensearch versions.

Fast NoSql document store for managing JSON objects with typed and schemaless data. Features developer-friendly APIs, asynchronous operations, indexing, and extensibility for custom serializers or storage backends.

Produces short deterministic string tokens for strict-length contexts using a compact PackedFormat (bitset headers, varints/zigzag), optional transforms (checksum, encryption, ECC), and Base62/36/64/85 codecs.

Serialize and deserialize ordered CSV and Fixed Length Format Files, leveraging a specific serialization library. Supports multiple platforms and offers easy integration via MavenCentral.

Library with tools for coroutines, serialization, database interaction, and networking. Modules include common utilities, selection tools, MIME types, pagination, and repository patterns, with a structured approach for complex modules.

Offers a set of serializers for common types, along with utilities for building custom serializers, supporting various serialization methods like contextual and typealias-based approaches.

Library facilitates easy serialization and deserialization of JSON:API documents into native types, supporting builder functions for document creation, with ongoing enhancements for domain type extraction.

Extensible, plugin-based debugging platform with runtime-loadable modules, DSL configuration, simultaneous session support, and type-safe serialized communication for customizable debugging workflows.

Experimental library enabling JSON5 serialization and deserialization with support for polymorphic types, class discriminators, comment serialization, concise error messages, and duplicate key rejection.

Standards-first WebAuthn and passkey building blocks: typed protocol models, strict validation, backend ceremony services, client orchestration, and modular transport, storage, crypto and attestation adapters.

YAML 1.2 serializer/deserializer integrating with a serialization framework, handling scalars, maps, sequences, anchors/aliases, polymorphism styles, and Docker Compose–style extension fields.

Implements CBOR serialization format with efficient byte usage, special serializers, and annotations for flexible encoding, supporting complex data structures and indefinite length handling.

Lightweight FHIR-inspired questionnaire engine with reactive state, JsonLogic-driven validation/visibility/calculations, type-safe models, extensible evaluator, rich UI widgets, pagination, repeating groups and themed summary view.

Implements `Either` and `Option` types for managing dual-value and optional state scenarios. Enhances serialization, deserialization, and transformation capabilities, providing flexible error handling and state management.

Modular object storage framework offering key/value storage with automatic key derivation. Features include various serialization methods, secure and file-based storage, and value transformation capabilities.

Fetches game information from IGDB, supporting HTTP clients, Twitch authentication, multi-queries, automatic retry, image URL helpers, and webhook integration. Offers server proxy configuration and request customization.

Serialization scheme for CSVs ensures durability, handling complex structures like sublists and polymorphism without failure. Encodes non-representable types using a fallback string format, defaulting to JSON. Handles non-standard CSVs and supports sequence and list reading with complex field handling.
