1. Project Overview

Pediatric AI Scribe is a clinical documentation platform for pediatric healthcare providers. It uses AI (via OpenRouter, AWS Bedrock, or Azure OpenAI) to generate:

• HPI notes from live encounter recordings
• SOAP notes from dictation
• Hospital course summaries
• Chart reviews
• Well-visit notes (including SSHADESS, ROS/PE, milestones)
• Sick visit notes
• Learning Hub content (articles, quizzes, clinical pearls, presentations)

Key design principle: Single-page application. All tabs are lazy-loaded HTML components (/public/components/*.html). JavaScript modules initialize only when their tab is first activated via the tabChanged custom event.

---

2. Architecture

Browser (Vanilla JS + Tiptap)
       |
       | HTTP (JWT Bearer token in Authorization header)
       |
Express.js (Node.js) — server.js
       |
       |— Helmet (CSP, security headers)
       |— CORS (restricted to APP_URL in production)
       |— express-rate-limit (login: 5/hr, register: 5/hr, general: 100/15min)
       |— cookie-parser
       |— Routes (/src/routes/)
       |
PostgreSQL (pg driver, no ORM)
       |
       |— users, app_settings, audit_log, saved_encounters
       |— user_memories, learning_*, access_log, api_log

AI providers (configured via environment variables, in priority order):

1. AWS Bedrock (if AWS_BEDROCK_REGION is set)
2. Azure OpenAI (if AZURE_OPENAI_ENDPOINT is set)
3. OpenRouter (default, requires OPENROUTER_API_KEY)

Important keys:

• registration_enabled — 'true' / 'false'
• announcement.enabled / announcement.text / announcement.type
• smtp.* — SMTP config (overrides env vars)
• ai.prompt.* — AI prompt overrides
• model.* — enabled/disabled models

saved_encounters

Draft encounters (7-day auto-expiry). Columns: label, enc_type, transcript, generated_note, partial_data (JSON), status, expires_at.

user_memories

User templates fed into AI generation. category is one of: physical_exam, ros, encounter_format, family_history, assessment_plan, custom.

Learning Hub Tables

6. Authentication System

Current implementation: JWT in localStorage

Flow

1. POST /api/auth/login → returns { success, token, user }
2. Frontend stores token in localStorage as ped_scribe_token and in window.AUTH_TOKEN
3. All API calls include Authorization: Bearer <token> header via getAuthHeaders()
4. src/middleware/auth.js validates the Bearer token, attaches req.user
5. Logout: clearSession() removes token from localStorage (client-side only)

Token

• Signed with JWT_SECRET env var
• 7-day expiry
• Payload: { userId: number }

Roles

• user — standard access (clinical tools only)
• moderator — can create/edit Learning Hub content
• admin — full access including user management and site settings

Middleware

• authMiddleware — validates JWT, populates req.user
• adminMiddleware — run after auth, requires role === 'admin'
• moderatorMiddleware — run after auth, requires role === 'admin' OR 'moderator'

2FA

Uses TOTP (speakeasy). If enabled, login returns { requires2FA: true } and the client must POST the TOTP code to complete login.

Session Check on Page Load (auth.js)

var savedToken = localStorage.getItem('ped_scribe_token');
if (savedToken) {
  fetch('/api/auth/me', { headers: { 'Authorization': 'Bearer ' + savedToken } })
  .then(/* if ok → enterApp(), else → clearSession() */);
}

The has-session CSS class on <html> hides the auth screen immediately when a localStorage token exists, preventing a white flash.

8. Frontend Architecture

Tab Loading (Lazy Components)

Every tab's HTML lives in /public/components/<tabname>.html. When a tab button is clicked, loadComponent() in app.js fetches the HTML, injects it into the tab section, then fires tabChanged event.

// app.js
document.dispatchEvent(new CustomEvent('tabChanged', { detail: { tab: tabName } }));

Critical pattern: Every JS module that needs to access tab DOM elements MUST listen for tabChanged, not DOMContentLoaded:

// Correct pattern for every tab module
(function() {
  var _inited = false;
  document.addEventListener('tabChanged', function(e) {
    if (e.detail.tab !== 'myTab' || _inited) return;
    _inited = true;
    // Now safe to querySelector elements — they exist in the DOM
    var btn = document.getElementById('my-btn');
    btn.addEventListener('click', ...);
  });
})();

If you use DOMContentLoaded instead, the elements won't exist yet (they're loaded async) and you'll get null.addEventListener errors.

Global Functions (defined in app.js)

These are available everywhere — no imports needed:

Function	Description
getAuthHeaders()	Returns { 'Content-Type': 'application/json', 'Authorization': 'Bearer <token>' }
getSelectedModel()	Returns model ID from active tab's selector or global selector
showLoading(msg)	Shows full-screen loading overlay
hideLoading()	Hides loading overlay
showToast(msg, type)	Shows toast notification. type: 'success'|'error'|'info'|'warning'
setOutputText(el, text)	Sets text on contenteditable div, converting \n to <br>
transcribeAudio(blob)	Sends audio blob to /api/transcribe, returns { success, text }
createSpeechRecognition()	Returns Web Speech API recognition instance
createTimer(el)	Returns timer object with .start() / .stop()

Rich Text Editor (Tiptap)

The body editor in the CMS uses Tiptap 2 (headless, no styling framework). The bundle is pre-built at /public/vendor/tiptap.bundle.js and exposes window.Tiptap = { Editor, StarterKit, Link, Underline, TextStyle, Color }.

To rebuild the bundle after updating Tiptap packages:

cat > tiptap-entry.js << 'EOF'
import { Editor } from '@tiptap/core';
import StarterKit from '@tiptap/starter-kit';
import Link from '@tiptap/extension-link';
import Underline from '@tiptap/extension-underline';
import { TextStyle } from '@tiptap/extension-text-style';
import { Color } from '@tiptap/extension-color';
window.Tiptap = { Editor, StarterKit, Link, Underline, TextStyle, Color };
EOF
npx esbuild tiptap-entry.js --bundle --format=iife --minify --outfile=public/vendor/tiptap.bundle.js
rm tiptap-entry.js

---

9. AI Integration

src/utils/ai.js — callAI(messages, options)

The single function used by all routes. It routes to the correct provider automatically.

const { callAI } = require('../utils/ai');

const result = await callAI(
  [{ role: 'user', content: 'Generate a note...' }],
  {
    model: 'google/gemini-2.5-flash', // optional, uses default if omitted
    temperature: 0.3,                 // optional, default 0.3
    maxTokens: 4000                   // optional, default 4000
  }
);

// result = { success: true, content: '...', model: '...', provider: '...', duration: ms }

Prompt System

Prompts are defined in src/utils/prompts.js. Admins can override any prompt via the Admin panel (/admin/config/prompts). Overrides are stored in app_settings table and loaded into memory on startup (with 3s grace period for DB readiness).

To add a new prompt:

1. Add a default in prompts.js
2. Use PROMPTS.get('your-prompt-key') in your route
3. The admin panel will auto-discover it

AI Generate for Learning Hub

The src/routes/learningAI.js file handles all Learning Hub AI generation.

For presentations: The AI is prompted to return raw Marp markdown (not JSON). The response is stored in the body column. Detection: content_type === 'presentation'.

For articles/quizzes/pearls: The AI returns JSON:

{
  "title": "...",
  "subject": "...",
  "body": "<p>HTML content</p>",
  "questions": [
    {
      "question_text": "...",
      "question_type": "mcq",
      "explanation": "...",
      "options": [
        { "option_text": "...", "is_correct": true, "explanation": "..." }
      ]
    }
  ]
}

10. Learning Hub & CMS

Content Types

Type	Body format	Has questions
article	HTML (Tiptap)	Optional
quiz	HTML (brief intro)	Always
pearl	HTML	Optional
presentation	Marp markdown	Never

Quiz Question Types

• mcq — Single choice (radio buttons), 4 options, 1 correct
• true_false — 2 options: "True" / "False", 1 correct
• multi — Multiple select (checkboxes), scoring: all correct chosen AND no incorrect chosen

PPTX Generation

POST /admin/learning/generate-pptx parses Marp markdown (splits on ---), extracts # headings as slide titles, bullet points as content, and uses pptxgenjs to create a real .pptx. No Chromium required — pure Node.js.

Slide Preview

POST /admin/learning/preview-slides uses @marp-team/marp-core to render Marp markdown to HTML, then extracts individual <section> elements. Returns { css, slides[] }. The frontend renders these one at a time in a full-screen modal with arrow key + swipe navigation.

Content Display

In the Learning Hub viewer, content body is rendered via sanitizeHtml() in learningHub.js. This function allows a safe subset of HTML tags only (no <script>, no on* attributes, no style attributes except class).

12. Known Issues & Security Notes

Active Known Issues

1. nodemailer HIGH vulnerability — v6.9.x has an email domain interpretation conflict. Upgrade to ^6.10.0 when available.
2. unsafe-inline in CSP — scriptSrc includes 'unsafe-inline' to support inline event handlers in HTML components. Should migrate to event listeners and remove this directive.
3. JWT in localStorage — Tokens stored in localStorage are readable by JavaScript and therefore vulnerable to XSS attacks. A future migration to httpOnly cookies would eliminate this risk. See notes in auth.js and Section 6.
4. window.prompt() in runAiRefineBody — Uses browser native prompt, which can be blocked in certain contexts. Should be replaced with an inline input field.
5. webdav-learning-path endpoint — Sits behind moderatorMiddleware but is a user preference that non-moderator users might reasonably need. Consider moving to plain authMiddleware.

Security Hardening Already In Place

• Helmet.js with custom CSP (no external script sources)
• CORS restricted to APP_URL in production
• Rate limiting on login (5/hr), register (5/hr), forgot-password (5/hr), general API (100/15min)
• bcrypt cost 12 for password hashing
• JWT with 7-day expiry
• SQL injection protection: all queries use parameterized ? / $1 placeholders
• Dynamic table names validated against an explicit allowlist (ALLOWED_SLUG_TABLES)
• User input in HTML contexts goes through sanitizeHtml() (tag allowlist, strips on* attributes)
• File upload MIME type validated by extension + content type
• Admin/moderator route protection via middleware

13. Adding New Features

Adding a New Clinical Tab

1. Create public/components/mytab.html with the tab's UI
2. Add to index.html:
   • Tab button: <button class="tab-btn" data-tab="mytab">...</button>
   • Tab section: <section id="mytab-tab" class="tab-content" data-component="mytab"></section>
   • Script tag: <script defer src="/js/myTab.js"></script>
3. Create public/js/myTab.js:

   (function() {
     var _inited = false;
     document.addEventListener('tabChanged', function(e) {
       if (e.detail.tab !== 'mytab' || _inited) return;
       _inited = true;
       // Wire up DOM elements here
     });
   })();
   

4. Create src/routes/myTab.js with the API route
5. Register in server.js: app.use('/api', require('./src/routes/myTab'));

Adding a New AI Prompt

1. In src/utils/prompts.js, add to the defaults object:

   'my-prompt': 'You are a pediatric physician...'
   

2. In your route: const prompt = PROMPTS.get('my-prompt') + '\n\n' + userInput
3. The admin panel will show an editor for this prompt automatically.

Adding a New Learning Hub Content Type

1. Add the new type to the content_type selector in cms.html
2. Handle it in toggleEditorMode() in learningHub.js
3. Add to the type detection in buildGeneratePrompt() in learningAI.js
4. Handle rendering in learningHub.js loadContent() function
5. No DB migration needed — content_type is a free-text column

14. Resetting Admin Password via Console

If you lose admin access and have no SMTP for password reset, use the Docker console:

# Step 1: Get a shell in the running app container
docker exec -it pediatric-ai-scribe sh

# Step 2: Open Node.js REPL
node

# Step 3: Hash your new password
const bcrypt = require('bcryptjs');
const hash = await bcrypt.hash('YourNewPassword123!', 12);
console.log(hash);
// Copy the hash output

# Step 4: Exit Node REPL
.exit

# Step 5: Open a DB shell
# (Exit app container first, then:)
docker exec -it pedscribe-db psql $POSTGRES_USER $POSTGRES_DB

# Step 6: Update the password (paste the hash)
UPDATE users
SET password = '$2a$12$...(your-hash-here)...'
WHERE email = 'your-admin@email.com';

# Verify:
SELECT email, left(password, 7) as hash_prefix FROM users WHERE email = 'your-admin@email.com';

# Exit:
\q

Enabling Registration via Console

docker exec -it pedscribe-db psql $POSTGRES_USER $POSTGRES_DB
UPDATE app_settings SET value = 'true' WHERE key = 'registration_enabled';
\q

Creating First Admin User (empty database)

The first user to register is automatically made admin. Enable registration, register, then disable registration again.

Or directly:

# In the Node REPL inside the app container:
const bcrypt = require('bcryptjs');
const { Pool } = require('pg');
const pool = new Pool({ connectionString: process.env.DATABASE_URL });
const hash = await bcrypt.hash('YourPassword', 12);
await pool.query(
  "INSERT INTO users (email, password, name, role, email_verified) VALUES ($1, $2, $3, 'admin', true)",
  ['admin@yourdomain.com', hash, 'Admin']
);
pool.end();
