ESLint
The pluggable JavaScript and TypeScript linter that finds and fixes code problems through a fully customizable, plugin-based rule engine.
lint-staged
Run linters and formatters only against the files staged in git, so a slow full-project lint never blocks a commit.
serde_json
The de facto standard JSON library for Rust, built on the Serde serialization framework
Requests
The elegant, human-friendly HTTP library that made Python's most-used API for talking to the web.
serde
A generic framework for serializing and deserializing Rust data structures efficiently and safely.
Pydantic
Data validation and settings management using Python type hints, backed by a Rust core.
pytest
The Python testing framework that makes writing small tests easy and scales to complex functional test suites.
Tokio
The async runtime powering most of Rust's networked, concurrent, and I/O-bound applications.
HTTPX
A next-generation HTTP client for Python with sync, async, and HTTP/2 support
Uvicorn
A lightning-fast ASGI server for Python, built on uvloop and httptools.
NumPy
The fundamental N-dimensional array library powering Python's scientific computing stack.
PyYAML
A full-featured YAML parser and emitter for Python, with C-accelerated bindings
FastAPI
A modern, high-performance Python web framework for building APIs with automatic validation, serialization, and interactive docs.
python-dotenv
Load environment variables from a .env file into Python's os.environ, the standard way to keep 12-factor config out of your code
Oxlint
Rust-based JavaScript/TypeScript linter that runs 50-100x faster than ESLint, with zero configuration required.
reqwest
An ergonomic, batteries-included HTTP client for Rust, with async and blocking APIs.
undici
A fast, spec-compliant HTTP/1.1 client for Node.js, built from scratch with zero runtime dependencies
tempfile
A secure, cross-platform Rust library for temporary files and directories that clean up automatically on drop.
base64
Correct, fast, and configurable base64 encoding and decoding for Rust, with pluggable alphabets and padding.
pandas
The Python DataFrame library for fast, flexible, and expressive data analysis and manipulation.
Pillow
The friendly PIL fork that adds image processing capabilities to Python
boto3
The official AWS SDK for Python — call every Amazon Web Services API from your code.
Stylelint
An extensible CSS linter that catches errors and enforces consistent styling conventions.
regex
Rust's finite-automata regex engine with guaranteed linear-time matching and no catastrophic backtracking.
