Juicebox Reference Architecture

Overview

Enterprise-grade reference architecture for Juicebox-powered recruiting and people search applications.

Architecture Patterns

Pattern 1: Simple Integration

┌─────────────┐     ┌─────────────┐     ┌─────────────┐
│   Client    │────▶│   Backend   │────▶│  Juicebox   │
│   (React)   │     │   (Node)    │     │    API      │
└─────────────┘     └─────────────┘     └─────────────┘

Best for: Small applications, MVPs, single-tenant systems

Pattern 2: Cached Architecture

Implementation

Core Components

1. API Gateway

// gateway/index.ts
import express from 'express';
import { createRateLimiter } from './middleware/rate-limiter';
import { authenticate } from './middleware/auth';
import { validateRequest } from './middleware/validation';

const app = express();

app.use('/api/v1/search', [
  authenticate,
  createRateLimiter({ windowMs: 60000, max: 100 }),
  validateRequest(searchSchema),
  searchController
]);

app.use('/api/v1/profiles', [
  authenticate,
  createRateLimiter({ windowMs: 60000, max: 200 }),
  validateRequest(profileSchema),
  profileController
]);

2. Service Layer

// services/people-search.service.ts
export class PeopleSearchService {
  constructor(
    private juicebox: JuiceboxClient,
    private cache: CacheService,
    private db: DatabaseService,
    private queue: QueueService
  ) {}

  async search(query: string, options: SearchOptions): Promise<SearchResult> {
    // Check cache first
    const cacheKey = this.getCacheKey(query, options);
    const cached = await this.cache.get(cacheKey);
    if (cached) return cached;

    // Perform search
    const results = await this.juicebox.search.people({
      query,
      ...options
    });

    // Cache results
    await this.cache.set(cacheKey, results, 300);

    
     (options.) {
       ..(, {
        : results..(, ).( p.)
      });
    }

     results;
  }

   (: ): <> {
    
     local =  ...({ : { id } });
     (local && !.(local)) {
       local;
    }

    
     profile =  ...(id);

    
     ...({
      : { id },
      : profile,
      : profile
    });

     profile;
  }
}

3. Worker Pool

// workers/enrichment.worker.ts
import { Worker } from 'bullmq';

const worker = new Worker('enrich-profiles', async (job) => {
  const { profileIds } = job.data;

  const enriched = await juiceboxService.enrichProfiles(profileIds);

  // Store enriched data
  for (const profile of enriched) {
    await db.profiles.upsert({
      where: { id: profile.id },
      create: { ...profile, enrichedAt: new Date() },
      update: { ...profile, enrichedAt: new Date() }
    });
  }

  return { enrichedCount: enriched.length };
}, { connection: redis });

4. Database Schema

-- PostgreSQL schema
CREATE TABLE profiles (
  id VARCHAR(255) PRIMARY KEY,
  name VARCHAR(500),
  title VARCHAR(500),
  company VARCHAR(500),
  location VARCHAR(500),
  email VARCHAR(255),
  phone VARCHAR(50),
  linkedin_url VARCHAR(500),
  skills JSONB,
  experience JSONB,
  education JSONB,
  raw_data JSONB,
  created_at TIMESTAMP DEFAULT NOW(),
  updated_at TIMESTAMP DEFAULT NOW(),
  enriched_at TIMESTAMP
);

CREATE INDEX idx_profiles_company ON profiles(company);
CREATE INDEX idx_profiles_location ON profiles(location);
CREATE INDEX idx_profiles_skills ON profiles USING GIN(skills);
