Core Actions

Basic action patterns: direct calls, async schemas, auth context, and output validation.

Direct Call

Basic action with inputSchema, invoked directly with useState.

Async Schema

inputSchema with an async factory function, schema is resolved at runtime.

Auth Context

authAction with chained .use() middleware, ctx.userId and ctx.sessionId available in the action.

Result:

No Arguments

Action without an input schema, just call it.

Using .outputSchema() to validate and transform the return data from the action: the greeting is uppercased by an output transform.

Result:
