Add an external Go module

External modules are project dependencies, not implicit downloads triggered by an import.

Create the project manifest

[project]
name = "uuid-demo"
version = "0.1.0"
go-module = "example.com/uuid-demo"
go-version = "1.23"

[go.interop]
unsafe = "deny"

Add and lock one exact version:

keika install --go-module github.com/google/uuid@v1.6.0
keika deps check
keika deps licenses

The install transaction writes [go.dependencies], kinmokusei.lock, and compiler-managed module state. If resolution or validation fails, it restores the previous project state.

Import the package

import go fmt from "fmt";
import go uuid from "github.com/google/uuid";

function main(): void {
  const id = uuid.New();
  fmt.Println(id.String());
}

Then normal operations use only the locked state:

keika check .
keika run .

They do not resolve a new version or edit the module graph. Use keika deps update, remove, or lock when you intend to change dependency state.

Before relying on an unfamiliar package surface, inspect its interop classification:

keika interop audit --json github.com/google/uuid

See Modules and projects and the Go interop matrix.
