TypeScript
A strongly typed superset of JavaScript that compiles to clean, portable JavaScript.
@babel/core
The core JavaScript compiler that transforms next-generation syntax into code every browser and runtime can understand.
Next.js
The React framework for production: file-based routing, server rendering, and Rust-powered builds.
esbuild
An extremely fast JavaScript and CSS bundler and minifier written in Go.
ts-node
TypeScript execution engine and REPL for Node.js that runs .ts files directly, without a separate compile step.
lint-staged
Run linters and formatters only against the files staged in git, so a slow full-project lint never blocks a commit.
Marked
A fast, low-level Markdown compiler that parses CommonMark and GFM into HTML in Node.js, browsers, or the CLI.
Requests
The elegant, human-friendly HTTP library that made Python's most-used API for talking to the web.
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.
webpack
A static module bundler that builds a dependency graph of your project's modules and packages them into optimized browser bundles
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.
tslib
The runtime library that houses TypeScript's compiler helper functions so your emitted code stays small.

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.
CodeMirror State
Immutable document, selection, and transaction data structures for the CodeMirror code editor
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
@monaco-editor/react
Drop the Monaco code editor into any React app without touching webpack, rollup, or bundler config files.
Oxlint
Rust-based JavaScript/TypeScript linter that runs 50-100x faster than ESLint, with zero configuration required.
undici
A fast, spec-compliant HTTP/1.1 client for Node.js, built from scratch with zero runtime dependencies
@codemirror/language
