Script Runner

Overview

The Script Runner wraps your script's main logic to automatically handle logging, status tracking (success/error), and progress updates. Script execution status can be viewed from "Script Logs" portal page.

Features

• Automatically logs the start and end of your script.
• Records the final status ('success' or 'error').
• Provides a simple function (trackProgress) to your script for logging custom progress steps.
• Captures script parameters and basic environment details.

Usage

1. Import scriptRunner.
2. Define your script's main logic as an async function that accepts trackProgress as its argument (can ignore trackProgress if you don't need to track progress).
3. Call scriptRunner, passing your function and any variables it needs.
4. Check script execution status by visiting the "Script Logs" portal page using the URL printed in the console output.

Example:

// Import the script runner utility (adjust the path as needed)
import { scriptRunner } from './lib/ScriptRunner.mjs'

const subJobs = 30

/**
 * Your script's main work goes here.
 * It must be an async function and accept `trackProgress`.
 * @param {(message: string) => void} trackProgress - Call this to log progress.
 */
async function main(trackProgress) {
  for (let i = 0; i < subJobs; i++) {
    await new Promise(resolve => setTimeout(() => resolve(), 1000))
    await trackProgress(`Job in progress ${i + 1}/${subJobs}`)
  }
  await trackProgress('Job finished')
}

// Define any variables your script needs (optional)
const scriptVariables = {
  subJobs,
}

// --- Execute the script using the runner with async/await ---
try {
  await scriptRunner(main, scriptVariables)
  process.exit()
} catch (error) {
  console.error(error)
  process.exit(1)
}
