Execution Engine

Execution Engine is a TypeScript library that enables tracing and visualization of code execution workflows in your project. Gain insights into the dynamic sequence of code execution by capturing detailed traces in JSON format, easily parseable into graphs.

Features ✨

Tracing: Trace the execution flow of code within your project.
Timing: Capture the timing of each executed function.
Visualization: Generate traces in JSON format for clear and insightful visualization.
- Easily parseable into graphs using tools like json-to-graph online demo.

Installation 📦

Use npm package manager:

npm install execution-engine

Or use the yarn package manager:

yarn add execution-engine

Usage 📚

Example 1: Basic Usage

import { ExecutionEngine } from "execution-engine";

const engine = new ExecutionEngine();

// for sync functions:
const res1 = engine.run((param) => `result1 for ${param}`, ['param1']);

// for async functions:
const res2 = await engine.run(async (param) => `result2 for ${param}`, [res1.outputs]);

// Retrieve the trace
const trace = engine.getTrace();
console.log('Trace:', trace);

You can:

view the complete code in examples/usage.ts
inspect the trace output in examples/usage.json.
visualize the trace graph using the json-to-graph online tool. → See the result ←

Example 2: Usage with Decorators

import { engine, run } from "execution-engine";

@engine({ id: "uniqueEngineId" })
class MyClass extends EngineTask {
  @run()
  myMethod1(param: string) {
    return `result1 for ${param}`;
  }

  @run()
  async myMethod2(param: string) {
    return `result2 for ${param}`;
  }
}

const myInstance = new MyClass();
myInstance.myMethod2("param1");
await myInstance.myMethod2("param2");

// Retrieve the trace
const trace = myInstance.engine.getTrace();
console.log("Trace:", trace);

You can:

view the complete code in examples/usage2.ts
inspect the trace output in examples/usage2.json
visualize the trace graph using the json-to-graph online tool. → See the result ←

Understanding the Trace 🧭

The trace object is an array containing nodes and edges. It has the following structure:

trace = [
  {
    data: {
      id: function_uuid1,
      label: "function"
      //... other properties of the result of the executed function as mentioned above 
    },
    group: nodes
  },
  {
    data: {
      id: function_uuid2,
      label: "function"
      //... other properties of the result of the executed function as mentioned above
    },
    group: nodes
  },
  {
    data: {
      id: function_uuid1 -> function_uuid2,
      source: function_uuid1,
      target: function_uuid2,
      parallel: false
    },
    group: edges
  }
];
