Talk to a Chronicle server from a Node.js or TypeScript application with @cratis/chronicle - reflect-metadata and decorator compiler settings, ChronicleClient and connection strings, @eventType classes, eventLog.append, reactors and reducers dispatched by camelCase method name, model-bound and declarative projections, variants (@variantOf/@entersOn/@globalFor or .variantOf()/.entersOn()) for an entity with mutually exclusive lifecycle shapes, glob-based artifact discovery, and the lazy connect…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# The Chronicle client for TypeScript `@cratis/chronicle` is a **standalone Node.js client SDK** that speaks gRPC to a Chronicle server. It is not a browser library and it is not the Arc TypeScript proxy layer — an Arc frontend calls generated command and query proxies over HTTP and never sees this package. ## Common pitfalls | Pitfall | Why it bites | | --- | --- | | Naming a reactor method after the handler's purpose | Use the camelCase event class name or explicit `@handles(EventType)` | | `instanceof` on the event inside a handler | It is a `JSON.parse`d plain object, not your class | | Event fields with no `@field` types under `tsx` | No type metadata is emitted; unresolved members make registration fail | | Two `@eventType()` classes sharing a class name | The id defaults to the class name and they collide | | Deploying compiled `dist/*.js` with default discovery | Compiled-JS entries do not scan; import artifact modules explicitly | | Omitting a side-effect import of an artifact module | Its decorator never runs, so it is never registered | | Forgetting `import 'reflect-metadata'` at the entry point | Decorators do not work at runtime | …

How to install
mdr add cratis/ai/cratis-chronicle-client-typescript@sha256:209e0f5b66980579The line at the top of this page pins the label git:20261014.db3fded, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
