@andreas-timm/cli

Helpers for building Bun and TypeScript CLIs on top of cac.

Features

• Register commands and aliases with a small typed wrapper around cac.
• Normalize multi-word commands, help, -h, and --help flows.
• Add declarative options with defaults, required flags, choices, and validation.
• Generate zsh completion, including option value choices and path inference.
• Install app CLIs into ~/.local/bin with a reusable command helper.

Install

npm install @andreas-timm/cli

Usage

import { cac } from "cac";
import {
    installDefaultCommandHelp,
    installSubcommandHelp,
    registerCommands,
    run,
} from "@andreas-timm/cli";

const cli = cac("example");

registerCommands(cli, ["build", "b"], "Build the project", (command) => {
    command.option("--watch", "Watch files");
    command.action(async (options) => {
        console.log("build", options);
    });
});

installDefaultCommandHelp(cli);
installSubcommandHelp(cli);

await run(cli);
