Lightweight MQTT tooling for easy connect/subscribe/publish with JSON serialization, Flow-based message streams, automatic reconnects and dynamic broker reconfiguration via config flows.

HTTP client wrapper simplifying API requests with flexible manual JSON navigation and automatic serialization-based decoding, handling messy or deeply nested API responses with configurable request helpers.

Renders JSON data as a collapsible, syntax‑colored tree with expandable objects/arrays, type‑based coloring, indentation via CompositionLocal, and configurable styling for spacing, colors, and counts.

Renders JSON elements as a collapsible, syntax‑colored tree with expandable objects/arrays, type‑based coloring, CompositionLocal-driven indentation, and configurable JsonViewerStyle (colors, spacing, counts).

Lightweight JSON query language enabling non-developers to run expressive, JMESPath-like queries with filters, wildcards, type and string checks, selections, and type-safe extraction.

Save and restore serializable objects to disk with asynchronous IO, in-memory caching, FIFO read–write locks, default values, migration helpers and observable updates via flows.

Serialization adapters and custom serializers for common data types, sealed classes, dates, enums and nullability, offering concise APIs and straightforward integration.

Auto-generates API clients from OpenAPI: single-file TypeScript client with Zod runtime validation, plus generated client libraries with configurable HTTP client and serialization support.

ViewModel-driven navigation architecture enabling sealed scenes, NavigationState actions (push/pop/present), SceneRepository for passing data, plus declarative UI integration and modal-stack manager.

Monorepo of small reusable libraries: cross-thread/coroutine-local context utilities, coroutine-friendly signal/observer primitives, and a composable action/expectation graph with dispatching helpers, including tests and a sample runtime demo.

Tiny runtime JSON config manager for fetching, caching and resolving application settings with conditional overrides, scheduled activation, string/semver matching and a client for automated retrieval.

Custom stepper component with composable UI, DSL-defined milestone roadmap, milestone-to-screen mapping, data aggregation, and built-in DI, coroutines, and serialization support for modular apps.

Tiny, Compose-first MVI toolkit enabling unidirectional state management via pure reducers, suspend side-effects and an interactor that folds events and upstream flows into StateFlow; easy to embed.

Full-stack CRUD toolkit with MongoDB/SQL backend-agnostic repository pattern, declarative view config, Tabulator grids, RBAC, change logs, file attachments, SSR, shared models, hooks, and API contract discovery.

MVI state management with ViewModel lifecycle, composable StateContent, reusable component DSL, typed navigation keys, Navigator API, predictive-back animations, ViewModelStore syncing and saveable backstack state.

Typed asynchronous clients for Twitch OAuth2, Helix REST API, EventSub WebSocket and IRC; stream-based auto-pagination, automatic EventSub reconnect/keepalive, pluggable token and logging.

Embeds QuickJS to fetch and run JavaScript modules at runtime, enabling hot-updates, bridged interfaces with serialization, modular caching, precompiled bytecode, profiling, and signature verification.

Type-safe suspendable navigation with result-passing (primitives and serializable objects), plus a lightweight MVI ViewModel interface to standardize UI state management.

OpenAI-compatible SDK offering chat completions (streaming and non-streaming), text embeddings, model browsing across 40+ models, SSE streaming, thread-safe singleton, and API-key redaction.

Streaming JSON parser emitting flat token events for incremental, chunked input; supports suspending reads, building or skipping value trees, and efficient selective field extraction.

Abstracts external services into swappable implementations (databases, caches, files, email/SMS/push/pubsub), with built-in metrics, health checks, local-run helpers and Terraform generation.

Lightweight utility extensions offering nullable defaults, safe string conversion, list/map manipulation (rotation, chunking, inversion), shared JSON serialization helpers, and callback-based exception handling.

BSON-first MongoDB client with ergonomic typed serialization and DSL builders for filters/updates; supports CRUD, sessions, transactions, SRV/TLS, index helpers, and a raw BSON escape hatch.

Application-level networking layer offering typed NetworkResult, structured NetworkError, ordered interceptor pipeline (auth single‑flight refresh, retry, circuit breaker), redacted logging, converters, test doubles.

Compile-safe, zero-boilerplate navigation with typed routes, arguments and results; three integration modes (annotation-based codegen, sealed-class DSL, class-based screens), shared-element transitions and back-with-result support.

Geospatial toolset: GeoJSON DSL with builders and JSON serialization, ported Turf.js spatial-analysis functions, plus unit-of-measure types and formatting utilities for distances.

Runs as an MCP server over stdio, implementing audio processing, subtitle‑to‑LRC and WAV→MP3 conversion, shell command execution, image understanding via Vision API, plus resource/prompt declarations.

Derives OpenAI function-tool schemas from serialization descriptors, turning sealed request hierarchies into SDK tool declarations and decoding model function calls into typed request objects.

Maps structured serialization models to deterministic SCREAMING_SNAKE_CASE environment variables and back into typed configs, supporting nested objects, indexed lists, encode-defaults control, and testable map-based API.

Deterministic pseudo-random generators with mutable Random implementations and serializable immutable-state snapshots for reproducible simulation, testing, procedural generation; includes Philox, Threefry, xoshiro and L64X128 with block APIs.
