Python Flask Web Stack Components | Generated by AI
Core Web Framework and Utilities
- Flask==2.0.3: Lightweight WSGI web framework for building web applications and APIs in Python. Provides routing, templating, and request handling.
- click==8.0.4: Library for creating command-line interfaces (CLI) with composable commands; often used with Flask for scripts or CLI tools.
- gunicorn==20.1.0: WSGI HTTP server for deploying Flask apps in production; supports multiple workers for concurrency.
- Werkzeug==2.0.3: Comprehensive WSGI utility library; powers Flask’s request/response handling, debugging, and routing.
- Jinja2==3.0.3: Templating engine for rendering dynamic HTML/templates in Flask apps.
- itsdangerous==2.0.1: Helps sign and serialize data securely (e.g., tokens, cookies) to prevent tampering.
- MarkupSafe==2.0.1: Escapes strings for safe HTML output in Jinja2 templates to prevent XSS.
- python-dotenv==0.19.2: Loads environment variables from a
.envfile intoos.environfor configuration management.
REST API and Extensions
- flask-restx==0.5.1: Extension for Flask that adds Swagger/OpenAPI support, input/output validation, and namespacing for building RESTful APIs.
- Flask-Cors==3.0.10: Handles Cross-Origin Resource Sharing (CORS) headers to allow cross-domain requests in Flask APIs.
- Flask-JWT-Extended==4.4.1: Manages JSON Web Tokens (JWT) for authentication; supports access/refresh tokens, blacklisting, and claims.
- aniso8601==9.0.1: Parses ISO 8601 date/time strings; used by flask-restx for handling datetime in API docs/models.
- jsonschema==4.0.0: Validates JSON data against JSON Schema definitions; integrates with flask-restx for API payload validation.
Database and ORM
- Flask-SQLAlchemy==2.5.1: Integrates SQLAlchemy ORM with Flask; simplifies database interactions, models, and sessions.
- SQLAlchemy==1.4.46: SQL toolkit and Object Relational Mapper (ORM) for database abstraction, querying, and migrations.
- greenlet==2.0.1: Lightweight coroutines for green threads; required by SQLAlchemy for async support (though not used here).
- Flask-Migrate: Extension for handling database schema migrations using Alembic; integrates with Flask-SQLAlchemy.
- pytz==2022.6: Provides timezone definitions and handling; used by SQLAlchemy/Flask for timezone-aware datetimes.
HTTP and Networking
- requests==2.27.1: Simple HTTP client for making API calls (e.g., to external services like OpenAI/Anthropic).
- certifi==2022.12.7: Collection of root certificates for verifying SSL/TLS connections in requests.
- charset-normalizer~=2.0.0: Detects character encodings in text; used by requests for response decoding.
- idna==3.4: Supports Internationalized Domain Names in Applications (IDNA) for URL handling.
- urllib3==1.26.13: HTTP client library with connection pooling and SSL; underlying engine for requests.
Authentication and Security
- PyJWT==2.4.0: Implements JSON Web Tokens for encoding/decoding JWTs; used by Flask-JWT-Extended.
Data Processing
- pandas==1.1.5: Data analysis library for manipulating structured data (DataFrames); useful for processing API inputs/outputs or logs.
AI/ML Integrations
- openai==0.8.0: Official client for OpenAI API; allows calling models like GPT for completions, embeddings, etc.
- anthropic==0.28.0: Client for Anthropic API (e.g., Claude models); similar to OpenAI for LLM interactions.
Monitoring and Logging
- prometheus_client==0.14.1: Generates metrics in Prometheus format for monitoring app performance (e.g., request latency, errors).
- logstash-formatter: Formats log messages in Logstash JSON format for compatibility with ELK stack (Elasticsearch, Logstash, Kibana).
- concurrent-log-handler: Rotating file handler that supports concurrent logging from multiple processes/threads without corruption.
Task Queue
- rq: Simple job queue for Python using Redis; enqueues background tasks (e.g., async API processing) with workers.
Testing and Packaging
- pytest==7.0.1: Testing framework for writing and running unit/integration tests.
- pluggy==1.0.0: Plugin system for pytest; manages hooks and extensions.
- py==1.11.0: Helpers for testing with subprocesses and fixtures; used by pytest.
- iniconfig==1.1.1: Parses INI files; used by pytest for config.
- tomli==1.2.3: TOML parser; handles pyproject.toml for pytest/build tools.
- attrs==22.1.0: Defines classes with attributes (like dataclasses); used by jsonschema and pytest.
- pyrsistent==0.18.0: Persistent data structures; used by jsonschema for immutable schema handling.
Python Compatibility and Utilities
- six==1.16.0: Compatibility utilities between Python 2 and 3 (legacy support, as this env targets older Python).
- packaging==21.3: Parses and compares version strings; used by build/test tools.
- importlib-metadata==4.8.3: Reads metadata from packages (backport for Python <3.8).
- importlib-resources==5.4.0: Reads resources from packages (backport for Python <3.9).
- zipp==3.6.0: Pathlib-compatible ZIP file access; used by importlib-metadata.
- pkgutil-resolve-name==1.3.10: Resolves package names (legacy import tools).
This setup appears to be for a Flask-based REST API with JWT auth, SQLAlchemy database, Swagger docs, background tasks via RQ, LLM integrations (OpenAI/Anthropic), monitoring, and testing. Versions are older (2021-2022), suggesting a legacy or pinned environment.
