Built-in Packages

Built-in packages provide dependencies and functions to build and run project tasks. Load symbols from a package with Starlark's load function.

Go

go, go_binary, go_install, go_run, go_test

Node.js

nodejs, npm_install, npm_run, npx_run

OS

env_append, env_get, env_prepend, env_set, env_unset, run

Zig

zig, zig_cc

Package names include a version. Tool packages use an exact tool version, while the OS package uses API version 1:

load("@[email protected]", "go_test")
load("@os@1", "env_set")
