Installation

Recommended: if you already have Node’s ecosystem tooling, npm install -g @edge_166/3va is the fastest path. If you work primarily in Rust, cargo install vvva_cli avoids depending on npm at all.

npm (all platforms)


npm install -g @edge_166/3va

Cargo (all platforms)


cargo install vvva_cli

Installs a 3va binary on $PATH — the crate is named vvva_cli (not 3va) because crates.io rejects package names starting with a digit.

Scoop (Windows)


scoop bucket add 3va https://github.com/OdinoCano/3va
scoop install 3va

Chocolatey (Windows)


choco install 3va

winget (Windows)


winget install OdinoCano.3va

Snap (Linux)


snap install vvva-cli

To build locally from source (for testing):


snapcraft --use-lxd   # uses dist/snap/snapcraft.yaml
sudo snap install ./vvva-cli_*.snap --dangerous

Nix

The flake lives under dist/nix/ in the repository:


nix run "github:OdinoCano/3va?dir=dist/nix"

Build from source


git clone https://github.com/OdinoCano/3va.git
cd 3va
cargo build --release
sudo cp target/release/3va /usr/local/bin/

Verifying the install


3va doctor
