cfa-simulator

Overview

This repository contains utilities for deploying interactive simulations using Python, Rust, and WebAssembly. It is still in the early stages of development so consider packages and APIs to be unstable.

Installing the cfasim CLI

# Shell (macOS / Linux)
curl --proto '=https' --tlsv1.2 -LsSf https://github.com/CDCgov/cfa-simulator/releases/latest/download/cfasim-installer.sh | sh

# PowerShell (Windows)
powershell -ExecutionPolicy Bypass -c "irm https://github.com/CDCgov/cfa-simulator/releases/latest/download/cfasim-installer.ps1 | iex"

# uvx (ephemeral — no install)
uvx cfasim init

# cargo
cargo install cfasim

Binaries installed via the shell/PowerShell installer can self-update with cfasim update. Copies installed via cargo or uvx are managed by those tools — update them with cargo install cfasim --force or uv tool upgrade cfasim instead.

To opt into a once-per-week "new version available" hint, create ~/.cfasim/settings.toml with check_for_updates = true.
