| +| `ALERT_TEMP_MIN_C` | Minimum temperature threshold (°C) | `15.0` | No | +| `ALERT_TEMP_MAX_C` | Maximum temperature threshold (°C) | `27.0` | No | +| `ALERT_HUMIDITY_MIN` | Minimum humidity threshold (%) | `30.0` | No | +| `ALERT_HUMIDITY_MAX` | Maximum humidity threshold (%) | `70.0` | No | + +### Alert Thresholds + +**Temperature Defaults:** +- Minimum: 15°C (59°F) +- Maximum: 27°C (80.6°F) + +**Humidity Defaults:** +- Minimum: 30% +- Maximum: 70% + +**Disabling Specific Alerts:** + +To disable a specific threshold, set it to an empty value in `.env`: + +```bash +# Disable low temperature alerts +ALERT_TEMP_MIN_C= + +# Disable high humidity alerts +ALERT_HUMIDITY_MAX= +``` + +### Periodic Status Updates + +In addition to threshold-based alerts, the monitor can send **scheduled periodic status updates** at regular intervals. + +**Configuration:** + +| Variable | Description | Default | Required | +|----------|-------------|---------|----------| +| `STATUS_UPDATE_ENABLED` | Enable periodic status updates | `false` | No | +| `STATUS_UPDATE_INTERVAL` | Interval in seconds | `3600` (1 hour) | No | +| `STATUS_UPDATE_ON_STARTUP` | Send update immediately on startup | `false` | No | + +**Common Intervals:** +- Every 30 minutes: `1800` +- Every hour (recommended): `3600` +- Every 2 hours: `7200` +- Every 4 hours: `14400` +- Daily: `86400` + +**Example Configuration:** + +```bash +# Enable hourly status updates +STATUS_UPDATE_ENABLED=true +STATUS_UPDATE_INTERVAL=3600 + +# Optionally send update on startup +STATUS_UPDATE_ON_STARTUP=true +``` + +**How It Works:** +- Independent of threshold alerts (sends even when all readings are normal) +- Provides regular confirmation that monitoring is working +- Useful for creating a historical record in Slack +- Minimum interval is 60 seconds (the sensor sampling rate) +- If webhook delivery fails, update is skipped and rescheduled for next interval + +**Benefits:** +- ✅ Confirms service is running and healthy +- ✅ Regular check-ins without manually opening dashboard +- ✅ Historical record if Slack messages are archived +- ✅ Combines with alerts for complete monitoring + +--- + +## API Endpoints + +All webhook endpoints require bearer token authentication via the `Authorization: Bearer ` header. + +### GET /api/webhook/config + +Get current webhook configuration. + +**Example

never rely solely on existing research documents +- Focus on finding concrete file paths and line numbers for developer reference +- Research documents should be self-contained with all necessary context +- Each sub-agent prompt should be specific and focused on read-only documentation operations +- Document cross-component connections and how systems interact +- Include temporal context (when the research was conducted) +- Link to GitHub when possible for permanent references +- Keep the main agent focused on synthesis, not deep file reading +- Have sub-agents document examples and usage patterns as they exist +- **CRITICAL**: You and all sub-agents are documentarians, not evaluators +- **REMEMBER**: Document what IS, not what SHOULD BE +- **NO RECOMMENDATIONS**: Only describe the current state of the codebase +- **File reading**: Always read mentioned files FULLY (no limit/offset) before spawning sub-tasks +- **Critical ordering**: Follow the numbered steps exactly + - ALWAYS read mentioned files first before spawning sub-tasks (step 1) + - ALWAYS wait for all sub-agents to complete before synthesizing (step 4) + - ALWAYS gather metadata before writing the document (step 5 before step 6) + - NEVER write the research document with placeholder values +- **Frontmatter consistency**: + - Always include frontmatter at the beginning of research documents + - Keep frontmatter fields consistent across all research documents + - Update frontmatter when adding follow-up research + - Use snake_case for multi-word field names (e.g., `last_updated`, `git_commit`) + - Tags should be relevant to the research topic and components studied diff --git a/.claude/flask-restx-api/.claude-plugin/plugin.json b/.claude/flask-restx-api/.claude-plugin/plugin.json new file mode 100644 index 0000000..c4bcbcd --- /dev/null +++ b/.claude/flask-restx-api/.claude-plugin/plugin.json @@ -0,0 +1,22 @@ +{ + "name": "flask-restx-api", + "version": "1.0.0", + "description": "Expert guidance for building Flask-RESTX APIs with webhooks, OpenAPI documentation, and security best practices", + "author": { + "name": "Claude Code Community", + "email": "community@anthropic.com" + }, + "keywords": [ + "flask", + "flask-restx", + "webhooks", + "openapi", + "swagger", + "rest-api", + "hmac", + "signature-verification", + "api-documentation" + ], + "license": "MIT", + "repository": "https://github.com/yourusername/flask-restx-api-plugin" +} diff --git a/.claude/flask-restx-api/README.md b/.claude/flask-restx-api/README.md new file mode 100644 index 0000000..0258511 --- /dev/null +++ b/.claude/flask-restx-api/README.md @@ -0,0 +1,279 @@ +# Flask-RESTX API Plugin + +Expert guidance for building Flask-RESTX APIs with webhooks, OpenAPI documentation, and security best practices. + +## Overview + +This Claude Code plugin provides comprehensive knowledge and patterns for: + +- **Flask-RESTX APIs** -

Document the current state of data validation in the codebase, the dataclass structures that would be affected, and the existing validation patterns. + +## Summary + +The codebase currently uses Python `@dataclass` decorators for structured data (`WebhookConfig`, `AlertThresholds`) with no runtime validation. API endpoints accept JSON data via `request.get_json()` with minimal existence checks. The issue proposes migrating to Pydantic to address three critical validation gaps: +- Issue #9: Missing numeric input validation in webhook config endpoint +- Issue #11: Unvalidated WebhookConfig construction +- Issue #12: Unvalidated AlertThresholds (no min < max check) + +Additionally, a Flask-RESTX skill is available in the project that provides an alternative approach using Flask-RESTX models for request validation and OpenAPI documentation. + +--- + +## Detailed Findings + +### 1.

-### Inaccurate Temperature Readings -- **Adjust:** Compensation factor in `get_compensated_temperature()` (line 127) -- **Check:** CPU temperature sensor accessible -- **Consider:** Enclosure affecting airflow -- **Verify:** Sense HAT firmly seated on GPIO pins - -### API Authentication Failures -- **Check:** `.env` file exists and contains BEARER_TOKEN -- **Verify:** Token format in Authorization header: `Bearer ` -- **Check:** Token matches exactly (case-sensitive) -- **Review:** Logs at `/home/fakebizprez/temp_monitor.log` for details - -### Web Dashboard Not Updating -- **Check:** Background sensor thread is running -- **Verify:** No exceptions in logs -- **Check:** Browser cache (hard refresh with Ctrl+F5) -- **Test:** API endpoint directly to verify data is being collected - ---- - -## Recent Changes & History - -### Latest Changes (Current Sprint) - -1. **Environment Variables Configuration** (6e1f06f) - - Replaced hardcoded paths with environment variables for logs - - Static assets now live in the `static/` directory instead of configurable paths - - Supports both absolute and relative paths for log configuration - -2. **Log File Path Validation** (43e866d) - - Added automatic creation of log directory if missing - - Proper error handling for directory creation failures - - Clear error messages if logging cannot be initialized - -3. **Static Asset Validation** (001e0a5) - - Added existence check for favicon file at startup - - Logs warning if favicon is missing - - Gracefully handles missing favicon without crashing (returns 404) - -4. **Security Enhancement** (0a6b4ff) - - Updated `.env.example` with instructions not to hardcode BEARER_TOKEN - - Token auto-generation is now the recommended approach - -5. **Development Infrastructure** (05dcd8d) - - Added Python cache files to `.gitignore` - - Includes `__pycache__/`, `*.pyc`, `*.pyo`, `*.pyd` - -### Evolution Pattern -- Started as simple temperature monitor -- Added API endpoints for programmatic access -- Enhanced security with bearer token authentication -- Ongoing refinement of error handling and edge cases -- Recent focus: Configuration management and file validation - ---- - -## Best Practices for AI Assistants - -### When Making Changes - -1. **Always read files before editing** - Never assume structure -2. **Update README.md** when adding features or changing APIs -3. **Add logging statements** for significant operations -4. **Handle hardware failures gracefully** - Sense HAT may not always be available -5. **Test with actual hardware** when possible -6. **Update this CLAUDE.md** when making architectural changes -7. **Follow existing code style** - spacing, naming conventions, etc. -8. **Consider deployment context** - This runs on Raspberry Pi, not cloud servers - -### Code Review Checklist - -- [ ] Hardware errors handled with try-except -- [ ] Logging added for new operations -- [ ] API endpoints have `@require_token` decorator (unless intentionally public) -- [ ] JSON responses use `jsonify()` -- [ ] Documentation updated (README.md, docstrings) -- [ ] Hardcoded paths reviewed (should use config/env vars) -- [ ] Thread safety considered for global variables -- [ ] Error messages are informative - -### Don't Do These Things - -- ❌ Remove hardware error handling (app must be resilient) -- ❌ Commit `.env` file (contains secrets) -- ❌ Make web dashboard require authentication without discussing (design decision) -- ❌ Change core temperature compensation without calibration data -- ❌ Add heavy dependencies (runs on resource-constrained Raspberry Pi Zero) -- ❌ Remove logging statements (critical for debugging headless deployments) -- ❌ Use blocking operations in sensor thread (would freeze monitoring) - ---- - -## Future Enhancement Ideas - -Areas where improvements could be made: - -1. **Database Integration:** Store historical data for trending analysis -2. **Alerting:** Email/SMS notifications for out-of-range conditions -3. **Graphing:** Historical charts in web dashboard -4. **Multi-sensor Support:** Monitor multiple rooms with multiple devices -5. **HTTPS Support:** SSL/TLS for secure remote access -6. **Docker Support:** Containerization for easier deployment -7. **Automated Testing:** Unit and integration test suite for critical functions -8. **Web Dashboard Auth:** Optional authentication for public deployments -9. **API Versioning:** `/api/v1/temp` for future compatibility -10. **Rate Limiting:** Implement rate limiting on API endpoints -11. **Token Expiration:** Add token expiration and rotation policies -

This feature monitors temperature and humidity thresholds and automatically sends notifications when readings are out of range. - -## Features - -- **Threshold-based alerts**: Automatic notifications when temperature or humidity exceeds configured limits -- **Slack integration**: Formatted messages with color-coded alerts -- **Retry logic**: Automatic retry with exponential backoff for failed deliveries -- **Rate limiting**: Built-in cooldown period (5 minutes) to prevent alert spam -- **API management**: Dynamic configuration via REST API endpoints -- **Thread-safe**: Safe concurrent access to webhook configuration - ---- - -## Quick Start - -### 1. Get a Slack Webhook URL - -1. Go to https://api.slack.com/messaging/webhooks -2. Click "Create your Slack app" -3. Choose "From scratch" and name your app (e.g., "Temperature Monitor") -4. Select the workspace where you want to receive notifications -5. Under "Incoming Webhooks", toggle "Activate Incoming Webhooks" to **On** -6. Click "Add New Webhook to Workspace" -7. Choose the channel for notifications (e.g., #server-room-alerts) -8. Copy the webhook URL (format: `https://hooks.slack.com/services/T00000000/B00000000/XXXXXXXXXXXXXXXXXXXX`) - -### 2. Configure the Application - -Add your webhook URL to `.env`: - -```bash -# Slack webhook URL -SLACK_WEBHOOK_URL=https://hooks.slack.com/services/YOUR/WEBHOOK/URL - -# Enable webhooks (optional, default: true) -WEBHOOK_ENABLED=true - -# Alert thresholds (optional, defaults shown) -ALERT_TEMP_MIN_C=15.0 # 59°F -ALERT_TEMP_MAX_C=27.0 # 80.6°F -ALERT_HUMIDITY_MIN=30.0 -ALERT_HUMIDITY_MAX=70.0 -``` - -### 3. Restart the Application - -```bash -# If running directly -python temp_monitor.py - -# If running with Docker -docker-compose restart -``` - -### 4. Test the Integration - -```bash -# Get your bearer token -TOKEN=$(grep BEARER_TOKEN .env | cut -d= -f2) - -# Send a test message -curl -X POST \ - -H "Authorization: Bearer $TOKEN" \ - http://localhost:8080/api/webhook/test -``` - -You should see a status update message in your Slack channel! - ---- - -## Configuration - -### Environment Variables - -| Variable | Description | Default | Required | -|----------|-------------|---------|----------| -| `SLACK_WEBHOOK_URL` | Slack incoming webhook URL | None | Yes | -| `WEBHOOK_ENABLED` | Enable/disable webhooks | `true` | No | -| `WEBHOOK_RETRY_COUNT` | Number of retry attempts | `3` | No | -| `WEBHOOK_RETRY_DELAY` | Base retry delay in seconds | `5` | No | -| `WEBHOOK_TIMEOUT` | HTTP request timeout in seconds | `10` | No | -| `ALERT_TEMP_MIN_C` | Minimum temperature threshold (°C) | `15.0` | No | -| `ALERT_TEMP_MAX_C` | Maximum temperature threshold (°C) | `27.0` | No | -| `ALERT_HUMIDITY_MIN` | Minimum humidity threshold (%) | `30.0` | No | -| `ALERT_HUMIDITY_MAX` | Maximum humidity threshold (%) | `70.0` | No | - -### Alert Thresholds - -**Temperature Defaults:** -- Minimum: 15°C (59°F) -- Maximum: 27°C (80.6°F) - -**Humidity Defaults:** -- Minimum: 30% -- Maximum: 70% - -**Disabling Specific Alerts:** - -To disable a specific threshold, set it to an empty value in `.env`: - -```bash -# Disable low temperature alerts -ALERT_TEMP_MIN_C= - -# Disable high humidity alerts -ALERT_HUMIDITY_MAX= -``` - -### Periodic Status Updates - -In addition to threshold-based alerts, the monitor can send **scheduled periodic status updates** at regular intervals. - -**Configuration:** - -| Variable | Description | Default | Required | -|----------|-------------|---------|----------| -| `STATUS_UPDATE_ENABLED` | Enable periodic status updates | `false` | No | -| `STATUS_UPDATE_INTERVAL` | Interval in seconds | `3600` (1 hour) | No | -| `STATUS_UPDATE_ON_STARTUP` | Send update immediately on startup | `false` | No | - -**Common Intervals:** -- Every 30 minutes: `1800` -- Every hour (recommended): `3600` -- Every 2 hours: `7200` -- Every 4 hours: `14400` -- Daily: `86400` - -**Example Configuration:** - -```bash -# Enable hourly status updates -STATUS_UPDATE_ENABLED=true -STATUS_UPDATE_INTERVAL=3600 - -# Optionally send update on startup -STATUS_UPDATE_ON_STARTUP=true -``` - -**How It Works:** -- Independent of threshold alerts (sends even when all readings are normal) -- Provides regular confirmation that monitoring is working -- Useful for creating a historical record in Slack -- Minimum interval is 60 seconds (the sensor sampling rate) -- If webhook delivery fails, update is skipped and rescheduled for next interval - -**Benefits:** -- ✅ Confirms service is running and healthy -- ✅ Regular check-ins without manually opening dashboard -- ✅ Historical record if Slack messages are archived -- ✅ Combines with alerts for complete monitoring -

- YYYY-MM-DD is today's date - - Examples: - - With ticket: `thoughts/tasks/eng-1478-parent-child-tracking/2025-01-08-research.md` - - Without ticket: `thoughts/tasks/authentication-flow/2025-01-08-research.md` - -6. **Generate research document:** - - Use the metadata gathered in step 4 - - Structure the document with YAML frontmatter followed by content: - ```markdown - --- - date: [Current date and time with timezone in ISO format] - researcher: [Researcher name from metadata] - git_commit: [Current commit hash] - branch: [Current branch name] - repository: [Repository name] - topic: "[User's Question/Topic]" - tags: [research, codebase, relevant-component-names] -

**Researcher**: [Researcher name from metadata] - **Git Commit**: [Current commit hash from step 4] - **Branch**: [Current branch name from step 4] - **Repository**: [Repository name] - - ## Research Question - [Original user query] - - ## Summary - [High-level documentation of what was found, answering the user's question by describing what exists] - - ## Detailed Findings - - ### [Component/Area 1] - - Description of what exists ([file.ext:line](link)) - - How it connects to other components - - Current implementation details (without evaluation) - - ### [Component/Area 2] - ... - - ## Code References - - `path/to/file.py:123` - Description of what's there - - `another/file.ts:45-67` - Description of the code block - - ## Architecture Documentation - [Current patterns, conventions, and design implementations found in the codebase] - - ## Related Research - [Links to other research documents in thoughts/tasks/] - - ## Open Questions - [Any areas that need further investigation] - ``` - -7. **Add GitHub permalinks (if applicable):** - - Check if on main branch or if commit is pushed: `git branch --show-current` and `git status` - - If on main/master or pushed, generate GitHub permalinks: - - Get repo info: `gh repo view --json owner,name` - - Create permalinks: `https://github.com/{owner}/{repo}/blob/{commit}/{file}#L{line}` - - Replace local file references with permalinks in the document - -8. **Present findings:** - - Present a concise summary of findings to the user - - Include key file references for easy navigation - - Ask if they have follow-up questions or need clarification - -9. **Handle follow-up questions:** - - If the user has follow-up questions, append to the same research document - - Update the frontmatter fields `last_updated` and `last_updated_by` to reflect the update - - Add `last_updated_note: "Added follow-up research for [brief description]"` to frontmatter - - Add a new section: `## Follow-up Research [timestamp]` - - Spawn new sub-agents as needed for additional investigation - - Continue updating the document - -## Important notes: -- Always use parallel Task agents to maximize efficiency and minimize context usage -- Always run fresh codebase research - never rely solely on existing research documents -- Focus on finding concrete file paths and line numbers for developer reference -- Research documents should be self-contained with all necessary context -- Each sub-agent prompt should be specific and focused on read-only documentation operations -- Document cross-component connections and how systems interact -- Include temporal context (when the research was conducted) -- Link to GitHub when possible for permanent references -- Keep the main agent focused on synthesis, not deep file reading -- Have sub-agents document examples and usage patterns as they exist -- **CRITICAL**: You and all sub-agents are documentarians, not evaluators -- **REMEMBER**: Document what IS, not what SHOULD BE -- **NO RECOMMENDATIONS**: Only describe the current state of the codebase -- **File reading**: Always read mentioned files FULLY (no limit/offset) before spawning sub-tasks -- **Critical ordering**: Follow the numbered steps exactly - - ALWAYS read mentioned files first before spawning sub-tasks (step 1) - - ALWAYS wait for all sub-agents to complete before synthesizing (step 4) - - ALWAYS gather metadata before writing the document (step 5 before step 6) - - NEVER write the research document with placeholder values -- **Frontmatter consistency**: - - Always include frontmatter at the beginning of research documents - - Keep frontmatter fields consistent across all research documents - - Update frontmatter when adding follow-up research - - Use snake_case for multi-word field names (e.g., `last_updated`, `git_commit`) - - Tags should be relevant to the research topic and components studied diff --git a/.claude/flask-restx-api/.claude-plugin/plugin.json b/.claude/flask-restx-api/.claude-plugin/plugin.json deleted file mode 100644 index c4bcbcd..0000000 --- a/.claude/flask-restx-api/.claude-plugin/plugin.json +++ /dev/null @@ -1,22 +0,0 @@ -{ -

-Installation: -```bash -pip install flask-restx -``` - -### Basic API Setup - -```python -from flask import Flask -from flask_restx import Api, Resource, fields - -app = Flask(__name__) -api = Api( - app, - version='1.0', - title='Webhook API', - description='API for receiving and processing webhooks', - doc='/docs' # Swagger UI endpoint -) -``` - -### Namespace Organization - -Organize related endpoints into namespaces for cleaner code structure: - -```python -from flask_restx import Namespace - -webhooks_ns = Namespace('webhooks', description='Webhook operations') -api.add_namespace(webhooks_ns, path='/api/webhooks') -``` - -### Model Definition - -Define request/response models for validation and documentation: - -```python -webhook_payload = webhooks_ns.model('WebhookPayload', { - 'event_type': fields.String(required=True, description='Type of event'), - 'timestamp': fields.DateTime(required=True, description='Event timestamp'), - 'data': fields.Raw(required=True, description='Event payload data'), - 'signature': fields.String(description='HMAC signature for verification') -}) - -webhook_response = webhooks_ns.model('WebhookResponse', { - 'status': fields.String(description='Processing status'), - 'message': fields.String(description='Response message'), - 'event_id': fields.String(description='Assigned event ID') -}) -``` - -### Field Types Reference - -| Field Type | Use Case | Validation Options | -|------------|----------|-------------------| -| `fields.String` | Text data | `min_length`, `max_length`, `pattern`, `enum` | -| `fields.Integer` | Whole numbers | `min`, `max` | -| `fields.Float` | Decimal numbers | `min`, `max` | -| `fields.Boolean` | True/False | - | -| `fields.DateTime` | ISO 8601 dates | - | -| `fields.List` | Arrays | Nested field type | -| `fields.Nested` | Embedded objects | Reference to another model | -| `fields.Raw` | Arbitrary JSON | - | - -### Request Validation with @expect - -Use the `@expect` decorator for automatic request validation: - -```python -@webhooks_ns.route('/receive') -class WebhookReceiver(Resource): - @webhooks_ns.expect(webhook_payload, validate=True) - @webhooks_ns.marshal_with(webhook_response, code=200) - @webhooks_ns.doc( - responses={ - 200: 'Webhook processed successfully', - 400: 'Invalid payload', - 401: 'Invalid signature', - 422: 'Validation error' - } - ) - def post(self): - """Receive and process incoming webhooks""" - data = webhooks_ns.payload - # Process webhook... - return {'status': 'success', 'message': 'Webhook received'} -``` - -### Webhook Signature Verification - -Implement HMAC-SHA256 signature verification for security: - -```python -import hmac -import hashlib -from functools import wraps -from flask import request, abort - -def verify_webhook_signature(secret_key): - """Decorator to verify webhook HMAC signatures""" - def decorator(f): - @wraps(f) - def decorated_function(*args, **kwargs): - signature = request.headers.get('X-Webhook-Signature') - if not signature: - abort(401, 'Missing signature header') - - payload = request.get_data() - expected = hmac.new( - secret_key.encode(), - payload, - hashlib.sha256 - ).hexdigest() - - if not hmac.compare_digest(f'sha256={expected}', signature): - abort(401, 'Invalid signature') - - return f(*args, **kwargs) - return decorated_function - return decorator -``` - -### Error Handling - -Register custom error handlers for consistent error responses: - -```python -@api.errorhandler(Exception) -def handle_exception(error): - """Global error handler""" - return { - 'error': str(error), - 'type': type(error).__name__ - }, getattr(error, 'code', 500) - -# For validation errors specifically -from werkzeug.exceptions import BadRequest - -@api.errorhandler(BadRequest) -def handle_bad_request(error): - return { - 'error': 'Validation failed', - 'details': error.description - }, 400 -``` - -### OpenAPI Customization - -Add metadata and customize the OpenAPI specification: - -```python -api = Api( - app, - version='1.0', - title='Webhook Service API', - description='Service for receiving and processing webhook events', - license='MIT', - contact='api@example.com', - authorizations={ - 'webhook_signature': { - 'type': 'apiKey', - 'in': 'header', - 'name': 'X-Webhook-Signature', - 'description': 'HMAC-SHA256 signature of request body' - }, - 'bearer': { - 'type': 'apiKey', - 'in': 'header', - 'name': 'Authorization', - 'description': 'Bearer token authentication' - } - }, - security='webhook_signature' -) -``` - -### Async Webhook Processing - -For high-volume webhooks, implement async processing: - -```python -from queue import Queue -from threading import Thread -import uuid - -webhook_queue = Queue() - -def process_webhook_worker(): - """Background worker for webhook processing""" - while True: - event = webhook_queue.get() - try: - # Process event asynchronously - handle_event(event) - except Exception as e: - logger.error(f"Failed to process event: {e}") - finally: - webhook_queue.task_done() - -# Start worker thread -worker = Thread(target=process_webhook_worker, daemon=True) -worker.start() - -@webhooks_ns.route('/async') -class AsyncWebhookReceiver(Resource): - @webhooks_ns.expect(webhook_payload, validate=True) - def post(self): - """Queue webhook for async processing""" - event_id = str(uuid.uuid4()) - webhook_queue.put({ - 'id': event_id, - 'payload': webhooks_ns.payload - }) - return { - 'status': 'queued', - 'event_id': event_id - }, 202 -``` - -## Implementation Workflow - -### Step 1: Project Setup - -```python -# requirements.txt -flask>=2.0.0 -flask-restx>=1.3.0 -python-dotenv>=1.0.0 -``` - -### Step 2: Application Structure - -``` -project/ -├── app/ -│ ├── __init__.py -│ ├── api/ -│ │ ├── __init__.py -│ │ ├── webhooks.py -│ │ └── models.py -│ └── utils/ -│ ├── __init__.py -│ └── security.py -├── config.py -└── run.py -``` - -### Step 3: Configure Flask-RESTX - -Initialize the API in `app/api/__init__.py`: - -```python -from flask_restx import Api - -api = Api( - title='My Webhook API', - version='1.0', - description='Webhook processing service', - doc='/docs' -) - -from .webhooks import webhooks_ns -api.add_namespace(webhooks_ns) -``` - -### Step 4: Define Models and Endpoints - -Create namespaced endpoints in `app/api/webhooks.py` following the patterns in this skill. - -### Step 5: Enable Validation - -Set global validation in Flask config: - -```python -app.config['RESTX_VALIDATE'] = True -app.config['RESTX_MASK_SWAGGER'] = False -``` - -## Common Patterns - -### Idempotency for Webhooks - -Prevent duplicate processing with idempotency keys: - -```python -processed_events = set() # Use Redis in production - -@webhooks_ns.route('/receive') -class WebhookReceiver(Resource): - def post(self): - event_id = request.headers.get('X-Idempotency-Key') - if event_id in processed_events: - return {'status': 'already_processed'}, 200 - - # Process webhook... - processed_events.add(event_id) - return {'status': 'success'}, 200 -``` - -### Retry Logic Documentation - -Document retry behavior in your OpenAPI spec: - -```python -@webhooks_ns.doc( - description=''' - Webhook receiver endpoint. - - **Retry Policy:** - - Returns 200 for successful processing - - Returns 202 for queued processing - - Returns 4xx for permanent failures (no retry) - - Returns 5xx for temporary failures (retry with backoff) - ''' -) -``` - -## Additional Resources - -### Reference Files - -For detailed patterns and advanced techniques, consult: -- **`references/webhook-patterns.md`** - Common webhook implementation patterns -- **`references/openapi-integration.md`** - Advanced OpenAPI configuration -- **`references/security-best-practices.md`** -

Complete OpenAPI specification - -## Integration Notes - -### With Existing Flask Apps - -Add Flask-RESTX to existing Flask applications: - -```python -from flask import Flask -from flask_restx import Api - -app = Flask(__name__) - -# Keep existing routes -@app.route('/health') -def health(): - return {'status': 'ok'} - -# Add API namespace for new endpoints -api = Api(app, doc='/api/docs', prefix='/api') -``` - -### Testing Webhooks - -Use tools like ngrok for local testing: - -```bash -# Expose local server -ngrok http 8080 - -# Test with curl -curl -X POST https://your-ngrok-url/api/webhooks/receive \ - -H "Content-Type: application/json" \ - -H "X-Webhook-Signature: sha256=..." \ - -d '{"event_type": "test", "data": {}}' -``` - -## Quick Reference - -### Essential Decorators - -| Decorator | Purpose | -|-----------|---------| -| `@ns.route('/path')` | Define endpoint URL | -| `@ns.expect(model)` | Validate request body | -| `@ns.marshal_with(model)` | Format response | -| `@ns.doc()` | Add documentation | -| `@ns.param()` | Document parameters | -| `@ns.response()` | Document response codes | - -### Validation Configuration - -```python -# Enable strict validation -app.config['RESTX_VALIDATE'] = True - -# Custom validation error code -app.config['RESTX_VALIDATION_ERROR_CODE'] = 422 -``` - -### Accessing Swagger Spec - -```python -# Get OpenAPI JSON spec -@app.route('/openapi.json') -def openapi_spec(): - return api.__schema__ -``` diff --git a/.claude/skills/flask-restx-webhooks/examples/basic-webhook.py b/.claude/skills/flask-restx-webhooks/examples/basic-webhook.py deleted file mode 100644 index f772ecc..0000000 --- a/.claude/skills/flask-restx-webhooks/examples/basic-webhook.py +++ /dev/null @@ -1,261 +0,0 @@ -""" -Basic Flask-RESTX Webhook Application -

Configure Environment ```bash -# Generate a secure token -python3 -c "import secrets; print(secrets.token_hex(32))" +cp .env.example .env -# Add to .env file: -# BEARER_TOKEN= +# Generate a bearer token (required) +python3 -c "import secrets; print(secrets.token_hex(32))" +# Add the output to .env as BEARER_TOKEN= ``` -The `.env` file is mounted as a volume, so the token will be available to the container. - -### Building Docker Image Manually - -If you prefer to build and run without docker-compose: +### 3. Run ```bash -# Build the image -docker build -t temp-monitor . - -# Run the container -docker run -d \ - --name temp-monitor \ - --privileged \ - -p 8080:8080 \ - -v $(pwd)/logs:/app/logs \ - -v $(pwd)/static:/app/static:ro \ - -v $(pwd)/.env:/app/.env \ - -v /sys:/sys:ro \ - --device /dev/i2c-1:/dev/i2c-1 \ - -e LOG_FILE=/app/logs/temp_monitor.log \ - temp-monitor -``` +# Development +python temp_monitor.py -### Important Docker Notes +# Production (with Waitress) +./start_production.sh -- **Privileged Mode:** The container requires privileged mode to access the I2C interface and hardware sensors on the Sense HAT -- **ARM Architecture:** This application is designed for ARM-based Raspberry Pi. The Python base image will automatically use the appropriate ARM variant -- **Device Access:** The container needs access to `/dev/i2c-1` for Sense HAT communication and `/sys` (read-only) for CPU temperature readings -- **Persistent Data:** Logs and the `.env` file are stored in mounted volumes, so they persist across container restarts -- **Auto-restart:** The docker-compose configuration includes `restart: unless-stopped` to automatically restart the container if it crashes or after system reboot +# Docker +docker-compose up -d +``` -## Production Deployment +Access the dashboard at `http://[raspberry-pi-ip]:8080` -For production deployments on Raspberry Pi 4, the application is optimized with: +## Configuration -- **Waitress WSGI Server**: Production-grade Python web server with single-process, single-thread configuration for resource efficiency -- **Health Check Endpoint**: `/health` endpoint for monitoring and load balancer integration -- **Metrics Endpoint**: `/metrics` for system and application metrics (CPU, memory, uptime, request counts) -- **Memory Monitoring**: Automatic detection and alerting for memory leaks -- **Systemd Integration**: Pre-configured systemd service with memory limits and restart policies -- **Docker Optimizations**: Memory limits, health checks, and resource constraints +All configuration is done via environment variables in `.env`.
