OpenJobs - Job Aggregation Platform

Microservices-based job aggregation platform with intelligent incremental sync

OpenJobs aggregates job listings from multiple sources into a unified API, featuring:

🔄 Incremental Sync - Only fetch new jobs, avoid duplicates
🐳 Microservices Architecture - Each connector runs independently
⏰ Cron Scheduling - Precise daily sync at 6:00 AM
📊 Database-backed State - No file-based persistence needed
🚀 High Limits - Fetch up to 500 jobs per connector

🎯 Current Status

Production Deployment: https://api.openjobs.ink
Legacy URL: https://app-openjobs.katsu6.easypanel.host (deprecated)

Connector	Jobs	Sync Method	Limit

🚀 Deployment

Quick Start (Easypanel)

1. Deploy Main API

Image: ghcr.io/magnusfroste/openjobs:latest
Port: 8080

Environment Variables:

SUPABASE_URL=https://supabase.froste.eu
SUPABASE_ANON_KEY=your-key-here
USE_HTTP_PLUGINS=true
CRON_SCHEDULE=0 6 * * *
PLUGIN_ARBETSFORMEDLINGEN_URL=http://plugin-arbetsformedlingen:8081
PLUGIN_EURES_URL=http://plugin-eures:8082
PLUGIN_REMOTIVE_URL=http://plugin-remotive:8083
PLUGIN_REMOTEOK_URL=http://plugin-remoteok:8084

2. Deploy Each Plugin

Create 4 services with these images:

ghcr.io/magnusfroste/openjobs-arbetsformedlingen:latest (Port 8081)
ghcr.io/magnusfroste/openjobs-eures:latest (Port 8082)
ghcr.io/magnusfroste/openjobs-remotive:latest (Port 8083)
ghcr.io/magnusfroste/openjobs-remoteok:latest (Port 8084)

Each needs:

SUPABASE_URL=https://supabase.froste.eu
SUPABASE_ANON_KEY=your-key-here
PORT=808X  # Respective port

EURES also needs:

ADZUNA_APP_ID=your-adzuna-id
ADZUNA_APP_KEY=your-adzuna-key

See EASYPANEL_ENV_SETUP.md for detailed instructions.

See existing connectors for examples.

� Getting an API Key

To post jobs via the API, you need an API key from OpenJobs_Web:

Register: Visit OpenJobs_Web
Create Account: Fill in your company details
Get API Key: Your unique API key is generated instantly
Use It: Include in X-API-Key header when posting jobs

# Example: Post a job with your API key
curl -X POST https://api.openjobs.ink/jobs \
  -H "Content-Type: application/json" \
  -H "X-API-Key: your-api-key-here" \
  -d '{"title":"Developer","company":"Acme","description":"..."}'

Features:

✅ Free forever
✅ Instant generation
✅ No credit card required
✅ Post unlimited jobs

�� Data Sync

Automatic Sync

Schedule: Daily at 6:00 AM (configurable via CRON_SCHEDULE)
Method: HTTP POST to each plugin container
Logging: All syncs logged to sync_logs table

Manual Sync

curl -X POST https://api.openjobs.ink/sync/manual

Incremental Sync Logic

API Date Filtering (Arbetsförmedlingen, EURES):

Query database for most recent job's posted_date
Add ?published-after=YYYY-MM-DD to API request
API returns only new jobs

Client-Side Filtering (Remotive, RemoteOK):

Fetch all jobs from API
Query database for most recent job's posted_date
Filter locally to only process new jobs
Skip transformation/insertion of duplicates

git clone https://github.com/magnusfroste/openjobs.git
cd openjobs
cp .env.example .env
# Edit .env with your Supabase credentials

2. Run Database Migrations

migrations/001_create_job_posts.sql
migrations/002_add_job_fields.sql

3. Start All Services

docker-compose -f docker-compose.plugins.yml up

This starts:

Main API: http://localhost:8080
Arbetsförmedlingen: http://localhost:8081
EURES: http://localhost:8082
