execution-engine/dist/execution/trace.decorator.d.ts

A TypeScript library for tracing and visualizing code execution workflows.

import { TraceContext } from './trace';
/**
 * Method decorator to trace function execution, capturing metadata, inputs, outputs, and errors.
 *
 * @param onTraceEvent - handle function of the trace context.
 * @param additionalContext - Additional metadata to attach to the trace context.
 * @param options - Configuration options:
 *   - `contextKey`: Key to store trace context on the instance.
 *   - `errorStrategy`: Determines whether errors should be caught (`'catch'`) or thrown (`'throw'`).
 *   - `injectContextInArgs` (boolean): Whether to inject the context (from `contextKey`) into the function arguments. Defaults to `false`.
 *
 * @returns A method decorator that wraps the original function with execution tracing.
