Here’s how to use the /invoke/stdout endpoint with Node.js to stream Server-Sent Events (SSE) from the Cloud Coding API. We’ll use the eventsource package, which simplifies handling SSE connections.

​
Installation

First, add the eventsource package to your project: 
npm install eventsource
# or
yarn add eventsource
The following examples use require for Node.js compatibility. If you are using ES modules, you can use import EventSource from 'eventsource'.

​
Single Task Invocation

This example invokes a single task and listens for updates and custom events from the stream. 
const EventSource = require('eventsource');
const { inspect } = require('util');

// --- Configuration ---
const API_KEY = 'YOUR_CLOUDCODING_API_KEY';
const GITHUB_TOKEN = 'YOUR_GITHUB_TOKEN';
const REPO_URL = 'https://github.com/username/repo-name';
const API_URL = 'https://api.cloudcoding.ai/invoke/stdout';

// --- Request Body ---
const body = {
  repo_url: REPO_URL,
  github_token: GITHUB_TOKEN,
  messages: [
    {
      type: 'human',
      content: 'analyze the repo to see what it is about',
    },
  ],
};

// --- EventSource Configuration ---
const eventSourceInitDict = {
  method: 'POST',
  headers: {
    'Content-Type': 'application/json',
    'x-api-key': API_KEY,
  },
  body: JSON.stringify(body),
};

console.log('Connecting to the API...');
const es = new EventSource(API_URL, eventSourceInitDict);

es.addEventListener('updates', (event) => {
    const data = JSON.parse(event.data);
    console.log("\n--- Received 'updates' event ---");
    console.log(inspect(data, { depth: null, colors: true }));
});

es.addEventListener('custom', (event) => {
    const data = JSON.parse(event.data);
    console.log("\n--- Received 'custom' event ---");
    console.log(inspect(data, { depth: null, colors: true }));
});

es.onerror = (err) => {
  console.error('EventSource failed:', err);
  if (err && err.status) {
    console.error(`Error: Status ${err.status}`);
  }
  es.close();
};

​
Parallel Task Invocation

This example runs two tasks in parallel. The custom event’s data includes a task_name, which you can use to identify which task produced the output. 
const EventSource = require('eventsource');
const { inspect } = require('util');

// --- Configuration ---
const API_KEY = 'YOUR_CLOUDCODING_API_KEY';
const GITHUB_TOKEN = 'YOUR_GITHUB_TOKEN';
const REPO_URL = 'https://github.com/username/my-app';
const API_URL = 'https://api.cloudcoding.ai/invoke/stdout';

// --- Request Body ---
const body = {
    "repo_url": REPO_URL,
    "github_token": GITHUB_TOKEN,
    "parallel_tasks": [
      {
        "prompt": "Add comprehensive error handling",
        "task_name": "error-handling"
      },
      {
        "prompt": "Create unit tests for all components",
        "task_name": "testing"
      }
    ]
};

// --- EventSource Configuration ---
const eventSourceInitDict = {
  method: 'POST',
  headers: {
    'Content-Type': 'application/json',
    'x-api-key': API_KEY,
  },
  body: JSON.stringify(body),
};

console.log('Connecting to the API for parallel tasks...');
const es = new EventSource(API_URL, eventSourceInitDict);

es.addEventListener('updates', (event) => {
    const data = JSON.parse(event.data);
    console.log("\n--- Received 'updates' event ---");
    console.log(inspect(data, { depth: null, colors: true }));
});

es.addEventListener('custom', (event) => {
    const data = JSON.parse(event.data);
    const taskName = data.data.task_name;
    const stdout = data.data.stdout;
    console.log(`\n--- Received 'custom' event for task: ${taskName} ---`);
    console.log(stdout);
});

es.onerror = (err) => {
  console.error('EventSource failed:', err);
  if (err && err.status) {
    console.error(`Error: Status ${err.status}`);
  }
  es.close();
};
