Quick Start

Installation

npm install sift-helper

Basic Usage

import { SiftClient, ChatbotSiftClient } from 'sift-helper';

const siftClient = new SiftClient({
  dataToken: process.env.SIFT_DATA_TOKEN!,
  mediaToken: process.env.SIFT_MEDIA_TOKEN
});

const chatbot = new ChatbotSiftClient(siftClient);

// Natural language queries
const manager = await chatbot.getPersonsManager('john@company.com');
const teamSize = await chatbot.howBigIsTeam('sarah@company.com');
const engineers = await chatbot.findPeopleByRole('software engineer');

Advanced Example with Skills

import { SiftClient, ChatbotSiftClient, SkillsClient } from 'sift-helper';

// Initialize with skills support
const siftClient = new SiftClient({ dataToken: process.env.SIFT_DATA_TOKEN! });
const chatbot = new ChatbotSiftClient(siftClient);

// Skills-based queries (automatic canonicalization handles aliases)
const reactDevs = await chatbot.findPeopleWithSkills(['React', 'TypeScript'], {
  requireAll: true,
  minLevel: 3,
  department: 'Engineering'
});

// Natural language skills queries
const response = await chatbot.whoKnowsSkill('javascript', 'Engineering');
// Returns: "Found 15 people with JavaScript skills in Engineering: Sarah (Level 5), John (Level 4)..."

// Organization-wide skills analytics
const skillsReport = await chatbot.getSkillsAnalytics();
console.log(`Top skills: ${skillsReport.topSkills.map(s => s.skill).join(', ')}`);

Chatbot Query Patterns

Organization Queries

Natural Language Query	Method Call
"Who is X's manager?"	whoIsManager(email)
"Who reports to X?"	whoReportsTo(email)
"How big is X's team?"	howBigIsTeam(email)
"Find all product managers"	findPeopleByRole('product manager')
"Who works in Engineering?"	whoWorksInDepartment('Engineering')
"Show me X's org chart"	getCompleteOrgTree(email)

Skills Queries

Natural Language Query	Method Call
"Who knows React?"	whoKnowsSkill('React')
"Who are the Python experts?"	whoAreTheExperts('Python')
"What skills does Jane have?"	whatSkillsDoesPersonHave(email)
"Find React and Node.js devs"	findPeopleWithSkills(['React', 'Node.js'], {requireAll: true})
"Who has similar skills to Bob?"	findPeopleWithSimilarSkills(email)

Core Methods

const person = await chatbot.findPersonByEmail('jane@company.com', true);
console.log(person.level, person.departmentName, person.photoUrl);

// Get their direct manager
const manager = await chatbot.getPersonsManager('jane@company.com');

// Get full reporting chain (all managers up to CEO)
const chain = await chatbot.getReportingChain('jane@company.com', true, true);

// Get direct reports
const directReports = await chatbot.getDirectReports('manager@company.com');

Team & Organization Analysis

// Get comprehensive team insights
const insights = await chatbot.getTeamInsights('manager@company.com');
console.log({
  totalTeamSize: insights.totalTeamSize,
  directReports: insights.directReports.length,
  teamDepth: insights.teamDepth,
  avgSpanOfControl: insights.avgSpanOfControl,
  largestSubteam: insights.largestSubteam
});

const sfPeople = await chatbot.findPeopleInOffice('San Francisco');

Search & Discovery

// Find people by job title/role with advanced filters
const seniorDevs = await chatbot.findPeopleByRole('software engineer', {
  department: 'Engineering',
  office: 'Seattle',
  minReports: 1,  // Managers only
  includePhotos: true,
  limit: 20
});

// Natural language search
const results = await chatbot.searchPeopleByQuery('senior frontend developer');

const filterableFields = fields.filter(f => f.filterable);

Skills-Based Search & Analytics

// Find people with specific skills (any of these skills)
const reactPeople = await chatbot.findPeopleWithSkills(['React', 'Vue', 'Angular'], {
  requireAll: false,  // OR logic
  minLevel: 3,        // Intermediate or better
  department: 'Engineering',
  limit: 10
});

// Find people with ALL specified skills
const fullstackDevs = await chatbot.findPeopleWithSkills(['React', 'Node.js'], {
  requireAll: true,   // AND logic
  limit: 5
});

// Get skill suggestions for autocomplete
const suggestions = await chatbot.getSkillSuggestions('java', 10);

// Find people with similar skills to someone

console.log(`Organization has ${allDepartments.length} departments`);

Low-Level API Access (SiftClient)

// Direct access to core Sift API methods
import { SiftClient } from 'sift-helper';

const client = new SiftClient({
  dataToken: process.env.SIFT_DATA_TOKEN!,
  mediaToken: process.env.SIFT_MEDIA_TOKEN
});

// Basic person lookup
const person = await client.getPerson('jane@company.com');

// Advanced search with boolean filters
const searchResults = await client.searchPeoplePost({
  q: 'developer',
  filter: {
    and: [
      { field: 'department', comparison: 'eq', value: 'Engineering' },
      { field: 'directReportCount', comparison: 'gte', value: 1 }
    ]
  },
  pageSize: 50,
  sortBy: 'displayName'
});

// Get organizational subtree (BFS traversal)
const subtree = await client.getOrgSubtree('ceo@company.com', {
  includeManager: true,
  maxDepth: 5,
  maxNodes: 1000
});

// Get reporting chain

Chatbot Integration Tips

1. Use descriptive method names: Methods are named to match natural language
2. Handle errors gracefully: All methods include proper error handling
3. Leverage convenience methods: Use whoIsManager(), whoReportsTo() for simple responses
4. Cache field metadata: The client automatically caches org schema
5. Include photos when needed: Set includePhotos: true for UI components

---

Data Enrichment

The ChatbotSiftClient automatically enriches person data with computed fields:

Field	Description	Example
level	Organizational level derived from reporting path	3 (VP level)
departmentName	Clean department name	"Engineering"
officeName	Office location	"San Francisco"
managerName	Direct manager's name	"Sarah Johnson"
photoUrl	Profile photo URL (when requested)	"https://..."

Benefits:

• ✅ No additional API calls required
• ✅ Consistent data formatting
• ✅ Ready for UI consumption
• ✅ Cached for performance

---

Advanced Usage

Custom Search Filters

const seniorEngineers = await chatbot.findPeopleByRole('engineer', {
  department: 'Engineering',
  minReports: 2,  // Senior ICs or managers
  office: 'Seattle',
  includePhotos: true,
  limit: 20
});

Org Chart Generation

const orgData = await chatbot.getCompleteOrgTree('vp@company.com', 4);

// Use with visualization libraries
const chartNodes = orgData.orgChart.nodes.map(person => ({
  id: person.id,
  label: person.displayName,
  title: person.title,
  level: person.level,
  photo: person.photoUrl
}));

const chartEdges = orgData.orgChart.edges;

Error Handling

All methods include comprehensive error handling:

try {
  const manager = await chatbot.getPersonsManager('unknown@company.com');
} catch (error) {
  console.log('Person not found or has no manager');
}

// Or use the convenience methods that return user-friendly strings
const response = await chatbot.whoIsManager('unknown@company.com');
// Returns: "This person doesn't have a manager listed."
