What Is It?

A tool for making command line tools with TypeScript or Javascript using Node.Js. It handles command line args, user input, help screen, colored messages, progress bars, and so on.

Why?

To make an easy chainable way to create a CLI fast. This provides a complete package for basic or advanced command line tools with many customizable options. The aim is to create an enjoyable and understadnable syntax that allows for efficent creation of command line user interfaces so developers can focus more on developing their applications.

How To Start

Vist The Wiki

Start a new node project and install typescript and dscom .

  npm init
  npm i --save-dev typescript @types/node
  npm i --save dscom

Make sure to set the type to module in the package.json file also.

In your typescript config file set the types and target to be.

{
    "target": "ESNext", 
    "module": "ESNext", 
    "moduleResolution": "node", 
    "types": ["node", "dscom"]
}

And then you can simply require the dsCom object and define it as DSCommander.

See the code bellow to get started quickly. It shows the program setting up input params, logging some text, and then asking for the user's input and displaying their input.

Starter Code

import * as readline from 'node:readline';
import {DSCommander} from "../../dist/index.js";
const dsCom = new DSCommander(readline);
(async () => {
    //Add params to the program
    dsCom
    .addParam({
        flag: "a",
        name: "auto",
        desc: "Auto parse",
        type: "string[]",
        required: false,
        valueNeeded: true,
    })
    .addParam({
        flag: "b",
        name: "batch",
        desc: "Batch parse",
        type: "boolean",
        required: false,
        valueNeeded: true,
    })
    .addParam({
        flag: "c",
        name: "cache",
        desc: "Cache",
        type: "boolean",
        required: false,
        valueNeeded: true,
    });
    //Get the params input
    (await dsCom.initProgramInput()).$ENABLESHOW //enable use of show functions
        .defineSleepTime(100)
