Uptask

Uptask scans your project for files matching a glob, parses each exported function's signature with the TypeScript compiler, and registers a Commander command for each one. No decorators, no boilerplate — just write functions.

Install

pnpm add -D uptask
# or
npm install --save-dev uptask

Write a task file

The default scan pattern is @*.ts. Create one anywhere in your project:

/**
 * Build the project.
 *
 * @param target Build target name
 * @param watch Enable watch mode
 * @param concurrency Number of parallel builds
 */
export function build(
  target: string,
  watch: boolean = false,
  concurrency: number = 4,
) {
  console.log({ target, watch, concurrency })
}

Required positional types (string, number) become arguments. Optional or boolean parameters become --flag options. JSDoc descriptions surface in --help.

Add a config file

A minimal uptask.config.ts at the project root:

import { defineConfig } from "uptask"

export default defineConfig({
  // pattern: "@*.ts" by default
  // groups: [] by default — see "Groups"
})

The config is optional. Without one, uptask uses sensible defaults derived from package.json.

Run

Add a bin entry or run via pnpm exec:

pnpm exec uptask --help
pnpm exec uptask build my-target --watch

Each exported function gets --help of its own — argument descriptions and default values come straight from the JSDoc and the parameter signature.
