jfrog-workers

name	JFrog Workers
description	Use when working with JFrog Workers -- creating serverless TypeScript functions, hooking into platform events, or building HTTP-triggered automations. Triggers on mentions of worker, serverless, event hook, TypeScript worker, BEFORE_DOWNLOAD, AFTER_CREATE, or custom platform logic.

API transport: Prefer jf api (JFrog CLI 2.100.0+). See jf-api-patterns.md (path-only URLs; auth from jf config). Examples using curl with $JFROG_URL + bearer token are fallback when the CLI is missing or below 2.100.0.

JFrog Workers Skill

Authentication

All requests require an access token via the Authorization header:

Authorization: Bearer $JFROG_ACCESS_TOKEN

Base URL: https://$JFROG_URL/worker/api/...

When authentication is needed, follow the login-flow.md procedure to resolve the active JFrog environment. The jf CLI is required and will be installed automatically if missing. The agent checks saved credentials via jf config show and asks which environment to use if multiple are saved. If none exist, the agent drives the web login flow and saves credentials via jf config add.

Core Concepts

Workers are serverless TypeScript functions that run inside the JFrog Platform, triggered by platform events or HTTP requests. They enable custom logic without external infrastructure.

Trigger Types

Type	When it runs
Event Hook	Automatically on platform events (e.g., artifact download, repo create)
HTTP Trigger	On-demand via HTTP request to a unique URL

Worker Lifecycle

Init (jf worker init) → Develop → Test (jf worker test) → Deploy (jf worker deploy) → Runs in Platform

Development Workflow

Initialize a New Worker

# Create worker scaffold
jf worker init my-worker --event BEFORE_DOWNLOAD

# Creates:
# my-worker/
# ├── worker.ts          # Main worker code
# ├── manifest.json      # Worker configuration
# └── tests/
#     └── worker.spec.ts  # Unit tests

manifest.json Structure

{
  "name": "my-worker",
  "description": "Block downloads of deprecated artifacts",
  "sourceCode": "worker.ts",
  "action": "BEFORE_DOWNLOAD",
  "enabled": true,
  "filterCriteria": {
    "artifactFilterCriteria": {
      "repoKeys": ["libs-release-local"]
    }
  }
}

Worker TypeScript Template

export default async (context: PlatformContext, data: BeforeDownloadRequest): Promise<BeforeDownloadResponse> => {
  const { repo_key, path } = data.metadata;
  
  // Check for deprecated property
  const props = await context.clients.platformHttp.get(
    `/artifactory/api/storage/${repo_key}/${path}?properties`
  );
  
  if (props.data?.properties?.deprecated?.[0] === 'true') {
    return {
      status: 'DOWNLOAD_STOP',
      message: 'This artifact is deprecated. Use the latest version.'
    };
  }
  
  return { status: 'DOWNLOAD_PROCEED' };
};

Deploy and Manage

# Test worker locally
jf worker test my-worker

# Deploy to platform
jf worker deploy my-worker

# List deployed workers
jf worker list

# Undeploy
jf worker undeploy my-worker

Key API Operations

# Create/deploy worker
curl -X POST -H "Authorization: Bearer $JFROG_ACCESS_TOKEN" \
  -H "Content-Type: application/json" \
  -d @manifest.json \
  "$JFROG_URL/worker/api/v1/workers"

# List workers
curl -H "Authorization: Bearer $JFROG_ACCESS_TOKEN" "$JFROG_URL/worker/api/v1/workers"

# Get worker
curl -H "Authorization: Bearer $JFROG_ACCESS_TOKEN" "$JFROG_URL/worker/api/v1/workers/my-worker"

# Update worker
curl -X PUT -H "Authorization: Bearer $JFROG_ACCESS_TOKEN" \
  -H "Content-Type: application/json" \
  -d @manifest.json \
  "$JFROG_URL/worker/api/v1/workers/my-worker"

# Delete worker
curl -X DELETE -H "Authorization: Bearer $JFROG_ACCESS_TOKEN" \
  "$JFROG_URL/worker/api/v1/workers/my-worker"

# Execute worker (HTTP trigger)
curl -X POST -H "Authorization: Bearer $JFROG_ACCESS_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"key":"value"}' \
  "$JFROG_URL/worker/api/v1/execute/my-worker"
