Multi-Module Worker

A worker composed of multiple ES modules, demonstrating how to split code across files and import JSON data.

File Structure

src/
  worker.mjs   - Entry point (fetch handler)
  utils.mjs    - Helper functions (formatGreeting, getTimestamp)
  config.json  - Static configuration imported as a JSON module

worker.mjs imports from both companion modules:

import { formatGreeting, getTimestamp } from './utils.mjs';
import config from './config.json';

All files in src/ are uploaded together. The main field in flameflare.toml identifies the entry point; the remaining files are available for import at runtime.

Deploy

See Environment Setup to configure FLAMEFLARE_URL, FLAMEFLARE_API_KEY, and FLAMEFLARE_ACCOUNT_ID.

ff deploy

Test

# Default greeting
curl "$FLAMEFLARE_URL/accounts/$FLAMEFLARE_ACCOUNT_ID/workers/multi-module/dispatch" \
  -H "Authorization: Bearer $FLAMEFLARE_API_KEY"

# Greeting with custom name
curl "$FLAMEFLARE_URL/accounts/$FLAMEFLARE_ACCOUNT_ID/workers/multi-module/dispatch?name=Alice" \
  -H "Authorization: Bearer $FLAMEFLARE_API_KEY"

# Health check (returns version from config.json)
curl "$FLAMEFLARE_URL/accounts/$FLAMEFLARE_ACCOUNT_ID/workers/multi-module/dispatch/health" \
  -H "Authorization: Bearer $FLAMEFLARE_API_KEY"

Expected responses

Default greeting:

{
  "message": "Hello, World! Welcome to FlameFlare Multi-Module Demo.",
  "timestamp": "2024-01-15T12:00:00.000Z",
  "config": {
    "appName": "FlameFlare Multi-Module Demo",
    "version": "1.0.0"
  }
}

Health check:

{
  "status": "ok",
  "version": "1.0.0",
  "timestamp": "2024-01-15T12:00:00.000Z"
}

This worker demonstrates

• ES module import/export between files
• JSON module imports (import config from './config.json')
• Code splitting for maintainability
• Automatic discovery and upload of all source files via ff deploy
