YDNAP - You don't need a package - CLI

Overview

YDNAP is a simple command-line tool that allows you to run JavaScript code snippets directly from the command line. It is designed to be lightweight and easy to use, easy to collaborate, without the need for any additional packages or dependencies.

Sick of installing packages just to archive a simple task? YDNAP is here to help!

In the end of the day, you maybe don't need Ramda, Lodash, date-fns, or any other package to do simple tasks.

CLI Options

Option	Type	Short	Default	Choices	Description
--verbose	boolean	-v	false	N/A	Enables verbose mode for detailed logging.
--extension	string	-e	js	js, ts	Specifies the file extension to use (js for JavaScript, ts for TypeScript).
--template	string	-t	N/A	N/A	Specifies the template folder to use.
--repo	string	-r	N/A	N/A	(Optional) Specifies the repository URL to fetch templates from.
--output	string	-o	N/A	N/A	(Optional) Specifies the output directory for generated files.

Installation

You can install YDNAP globally using npm:

npm install -g ydnap

Or you can use it without installing it by using npx:

npx ydnap

Usage

You can use YDNAP and create files using our templates, or you can create your own templates (or share them with your friiiiends).

To use our template, you can run:

ydnap -t sum # or npx ydnap -t sum

by default, we will always find the javascript file.

you can also specify the typescript file:

ydnap -t sum -l ts # or npx ydnap -t sum -l ts

Using you repository (eg https://github.com/alexcastrodev/ydnap-example/tree/main/src/even)

ydnap -u alexcastrodev/ydnap-example -t even

Note
It's mandatory that the -t (template) argument points to a folder, and the file inside the folder should be named index.ts or index.js.

Drawbacks

YDNAP is designed to solve small tasks, like navigating through objects with JavaScript or TypeScript (without needing the full weight of libraries like Ramda or Lodash), or creating a useDebounceCallback for React without installing an entire hooks library.

However, unlike libraries such as Lodash—which build complex functions by reusing internal utilities—YDNAP templates are intentionally isolated. This means that if you rely heavily on YDNAP for large-scale data manipulation, you may encounter duplicated logic across different utilities, since each template is designed to stand alone. This isolation ensures you don't have to install a large library when you only need a few specific tools.

Similarly, for working with dates: if you need a simple isBetween utility inspired by date-fns, YDNAP is a great lightweight choice. But if your application has extensive date-related logic, using a full-featured library may be more appropriate to avoid redundancy and improve maintainability.
