MoonBit b2 client: This library can be used to communicate with Backblaze B2.

Experimental Spin SDK for the MoonBit programming language.

moonctl (mctl) — a spec-driven code generator for MoonBit (← goctl): parse a .api service spec and emit compilable moonapi scaffolding (routes + handler stubs).

moonorm — an ORM / SQL toolkit for MoonBit (← SQLAlchemy / SQLModel): a parameterized, injection-safe query builder (select / insert / update / delete).

Pure-MoonBit MySQL wire-protocol driver implementing @moondb.Driver — no C, like PyMySQL.

moonzero — a service framework for MoonBit (← go-zero): config-driven assembly of a moonapi application with middleware, producing a runnable moonasgi AsgiApp. v0.6.2 runs real unary, server/client-streaming, and bidirectional zRPC calls over moonrpc's h2c transport (an in-process RpcChannel drives HPACK HEADERS + length-prefixed DATA + grpc-status trailers through the H2Server engine), graceful shutdown draining in-flight calls, a persisted, watchable etcd v3-shaped registry (watch, events_since catch-up, snapshot/restore) with round-robin/pick-first balancers and a load-balanced client, real file-backed registry I/O over moonbitlang/async's fs with a live filesystem watcher (native discov driver), request metrics (counter + latency histogram), and W3C traceparent propagation.

Pure-MoonBit PostgreSQL wire-protocol driver implementing @moondb.AsyncDriver — no C, like asyncpg.

SQLite driver for moondb/moonorm — native FFI, amalgamation vendored here (isolated).

mooncat — a native ASGI 3.0 server for MoonBit (← uvicorn), built on moonbitlang/async and the moonasgi SEAM.

mooncat — a native ASGI 3.0 server for MoonBit (← uvicorn), built on moonbitlang/async and the moonasgi SEAM.

moonapi — a typed web framework for MoonBit (← FastAPI): routing, typed extractors, descriptor-driven validation, multi-version OpenAPI/Swagger (2.0 / 3.0 / 3.1) with security schemes, dependency injection, OAuth2 password-bearer with self-built HS256 JWT and scopes, per-operation security enforcement, multipart/urlencoded form and file extractors, response_model filtering, background tasks, sub-application mounting, a CORS/gzip(real DEFLATE)/exception-handler middleware stack with per-status handlers, Server-Sent Events, and WebSocket routes, on the moonasgi SEAM.

moongql — a code-first GraphQL library for MoonBit (← strawberry-graphql): define object types and fields in code, emit the schema SDL.

The standard database-access interface for MoonBit — the driver↔query-layer contract, transliterated from Go's database/sql/driver and Python's DB-API 2.0. ORMs (moonorm) build on it; drivers (moonsqlite / moonpostgres / moonmysql) implement it.

moonkoog — a MoonBit port of JetBrains Koog (1.1.1): a type-safe agent-orchestration framework. The prompt/message model, LLM client contract, tool registry with a JSON-schema descriptor model, and the AIAgent tool-calling loop (Koog's singleRunStrategy), built to compose with the moon-heke full-stack suite.

moonrpc — a real gRPC implementation for MoonBit (← gRPC). v0.8.1 adds Channel::stream_take, which drives a streaming call inline — no background reader — and returns once it has collected a bounded number of reply messages, so a caller can consume the first N of an unbounded subscription (etcd's Watch, a long server-streaming feed) and close, keeping the whole exchange in one task. v0.8.0 completes the client channel stack. Load balancing picks a READY sub-connection per call (pick_first or round_robin) from a connection pool that tracks each address through the gRPC connectivity states (IDLE/CONNECTING/READY/TRANSIENT_FAILURE/SHUTDOWN); a ManagedChannel dials several backends over real sockets and routes calls through the picker. Name resolution self-builds a DNS message codec (RFC 1035, A/AAAA with name compression) and a UDP resolver, so dns_connect turns a hostname into the backends it dials. Retry and hedging policies drive re-issue and parallel attempts — hedging fires a fresh attempt every hedging delay and commits on the first fatal status, cancelling the rest. Client keepalive pings an idle connection and closes it on a missed ACK. A multiplexed channel (MuxChannel) carries many concurrent calls over one connection through a shared read pump with per-stream inboxes and serialized writes, drives keepalive, and supports interactive bidirectional streaming — send while receiving, replies read message by message. v0.7.0 adds per-message gzip: a self-built DEFLATE (RFC 1951, stored/fixed/dynamic-Huffman) and gzip (RFC 1952, CRC-32 + ISIZE) reader that decompresses gzip requests on the server and gzip responses on the client, and client-side retry with exponential backoff bounded by the call deadline. It also hardens every decoder against malformed input: the gRPC length prefix, HPACK integer/string, protobuf, and health decoders now reject an out-of-range or overflowing length instead of aborting; flow-control windows saturate rather than wrap; peer SETTINGS are validated; the client reassembles a response header block across CONTINUATION; and header blocks and message sizes are capped. v0.6.1 self-builds a pure protobuf wire runtime (PbWriter/PbReader for varint, zigzag, fixed32/64, and length-delimited fields) and Server Reflection: a descriptor model and the grpc.reflection.v1.ServerReflection service (with its v1alpha alias) answering ListServices, FileContainingSymbol, and FileByFilename. v0.6 added the client half — a real Channel, a long-lived multiplexed h2c connection over @socket.Tcp driven by a pure H2Client engine symmetric to the server — plus the grpc.health.v1.Health service, server interceptors, -bin metadata, google.rpc.Status rich errors, and client-side grpc-timeout enforcement. The server engine (H2Server) serves all four call kinds over the self-built HTTP/2 (h2c) transport, driving the RFC 7540 frame layer, the stream state machine, complete HPACK (RFC 7541, with Huffman + dynamic table), and connection- and stream-level flow control. Includes the shared length-prefixed framing and the 17-code gRPC status model.
