Week 2: Authentication, Performance, and Your First Case Study

Week 2: Authentication, Performance, and Your First Case Study

Week 1 gave you the foundations. Week 2 goes deeper.

Here's what we're publishing next week:

Monday: Authentication Deep Dive

OAuth, API keys, JWTs - what to use and when.

// Sneak peek: Multi-tenant auth pattern
const client = new FerniClient({
  apiKey: process.env.FERNI_API_KEY,
  auth: {
    type: 'jwt',
    issuer: 'your-app',
    audience: 'ferni-api',
    // Automatic token refresh
    refreshThreshold: 300,
  },
  tenantId: user.organizationId,
});

We'll cover:

  • When to use API keys vs OAuth vs JWTs
  • Multi-tenant authentication patterns
  • Secure token storage
  • Refresh token best practices

Tuesday: Performance Optimization

How we achieve sub-200ms response times - and how you can too.

Topics:

  • Connection pooling strategies
  • Context window optimization
  • Parallel processing patterns
  • Caching for voice AI

Wednesday: Changelog

Automated release notes from our latest deployment. Subscribe to never miss an update.

Thursday: Community Spotlight

Our first case study featuring a developer building voice AI for healthcare. Real metrics, real code, real learnings.

Friday: Error Handling Patterns

Beyond try/catch - building resilient voice applications:

// Preview: Retry with exponential backoff
const response = await withRetry(
  () => client.process(input),
  {
    maxAttempts: 3,
    backoff: 'exponential',
    onRetry: (attempt, error) => {
      // Optionally inform user
      if (attempt > 1) {
        speak("Just a moment, reconnecting...");
      }
    },
  }
);

Saturday: Voice AI vs Chatbots

A developer's perspective on when to use which - and why voice wins for certain use cases.

Sunday: Week 3 Preview

Next up: Testing strategies, deployment patterns, and more community projects.
