Getting Started

Prerequisites

• Node.js 20.x (see .nvmrc)
• npm
• AWS CLI (for deployment)

Installation

git clone https://github.com/thechrisgrey/thechrisgrey.git
cd thechrisgrey
npm install

Development

npm run dev             # Start dev server at http://localhost:5173
npm run build           # Full production build
npm run preview         # Preview production build
npm run lint            # Run ESLint

Build Pipeline

The production build runs these steps in sequence:

validate-env -> podcast-episodes -> lint -> tsc -> vite build -> sitemap -> rss

---

Testing

Framework	Scope	Command
Vitest	Unit + Integration	npm test
Vitest	Watch mode	npm run test:watch
Vitest	Coverage report	npm run test:coverage
Cypress	E2E (headless)	npm run cy:run
Cypress	E2E (interactive)	npm run cy:open
node:test	Lambda unit + contract	npm run test:lambda

The test suite includes unit tests for components, hooks, and utilities; integration tests for page-level behavior; and end-to-end tests covering navigation, chat, blog, and contact flows.

Live-API contract tests (opt-in)

Critical external boundaries — Cognito admin auth, the live Sanity client, Bedrock KB retrieval, and the Bedrock guardrail — are also covered by opt-in contract tests that exercise the real services (green mocks alone can drift from reality). They skip cleanly during npm run test:lambda and CI, and only run when their flag + AWS/Sanity credentials are present:

COGNITO_CONTRACT_TESTS=1 COGNITO_CLIENT_ID=… COGNITO_TEST_EMAIL=… COGNITO_TEST_PASSWORD=… \
  node --test lambda/shared/__tests__/cognito-contract.test.mjs
SANITY_CONTRACT_TESTS=1      node --test lambda/chat-stream/__tests__/sanity-contract.test.mjs
KB_RETRIEVE_CONTRACT_TESTS=1 node --test lambda/chat-stream/__tests__/kb-retrieve-contract.test.mjs
BEDROCK_CONTRACT_TESTS=1     node --test lambda/blueprint/__tests__/guardrail-contract.test.mjs

See .env.example for the full list of flags and required permissions. Run these before a release (or on a scheduled job) to catch response-shape/schema drift that unit mocks can't.

---

Environment Variables

Set in AWS Amplify console or in a local .env file:

Variable	Description	Required
VITE_CHAT_ENDPOINT	Lambda Function URL for AI chat	Yes
VITE_CONTACT_ENDPOINT	Lambda Function URL for contact form	Yes
VITE_NEWSLETTER_ENDPOINT	Lambda Function URL for newsletter	Yes
VITE_COGNITO_USER_POOL_ID	Cognito User Pool ID (admin auth)	Yes
VITE_COGNITO_CLIENT_ID	Cognito App Client ID	Yes
VITE_KB_BUILDER_ENDPOINT	Lambda Function URL for KB admin	Yes
VITE_CHAT_SIGNING_KEY	HMAC signing key for chat requests	Yes
VITE_METRICS_ENDPOINT	Lambda Function URL for metrics	Yes
YOUTUBE_API_KEY	YouTube Data API v3 key (build-time only)	Yes

VITE_ prefixed variables are bundled into the frontend. YOUTUBE_API_KEY is only used during the build step.

---

Deployment

Automatic (Recommended)

Push to main triggers automatic Amplify deployment:

git push origin main

Manual Rebuild

aws amplify start-job \
  --app-id d3du8eg39a9peo \
  --branch-name main \
  --job-type RELEASE \
  --region us-east-2

Lambda Deployment

Each Lambda function is deployed independently via a single verified script. The script installs from the lockfile, dereferences the lambda-shared symlink into the bundle, and verifies the entire module graph resolves before upload — so a deploy can no longer ship a Lambda that crashes on cold start.

# Verify the bundle builds and resolves, without uploading:
npm run deploy:lambda -- chat-stream --dry-run

# Deploy for real:
npm run deploy:lambda -- chat-stream

Works for any Lambda under lambda/ (e.g. chat-stream, blueprint, kb-builder, metrics, kb-sync, mcp-server). Pass --region <r> to override the default (us-east-1). Do not hand-build function.zip — the manual zip glob omits the sibling modules each handler imports and produces a broken artifact.

Key Integrations

Sanity CMS (Blog)

• Project ID: k5950b3w | Dataset: production
• Content includes blog posts with categories, tags, series, and Portable Text rich content
• Client-side caching via postCache.ts with Date revival

YouTube Data API (Podcast)

Episodes are fetched at build time from the @AltivumPress channel.

1. generate-podcast-episodes.js runs during the build step
2. Fetches channel, uploads playlist, and video details
3. Generates src/data/generatedEpisodes.json
4. Falls back to static data if the API is unavailable

Amazon Bedrock (AI Chat)

• Model: Claude Haiku 4.5 (us.anthropic.claude-haiku-4-5-20251001-v1:0)
• Knowledge Base: ARFYABW8HP (autobiography chunks)
• Guardrail: 5kofhp46ssob (content filtering)
• Rate Limit: 20 requests/hour per IP (DynamoDB-backed)
• Streaming responses via Lambda Function URL with RAG retrieval (5 chunks per query)

Cloudflare Web Analytics

Privacy-friendly, cookie-free analytics with no personal data collection.
