DemoScript

This package allows you to create interactive demos for your projects. It automatically finds all demos and provides a menu to run them. You can ask user for input, show messages, and more.

Installation

Inside your project directory, run:

npm install demoscript -D

Usage

• Make demos by creating files ending with .demo.ts.
• Inside package.json scripts, add a script to run demoscript. Optional path to demo folder can be provided. By default, it looks for all .demo.ts files in the entire project directory (including node_modules).

{
  "scripts": {
    "demo": "demoscript"
    // or
    "demo": "demoscript --path src/demos"
  }
}

• Now run the script using npm run demo (or whatever name you gave to the script). It will collect all demos and create a menu to run them.

Example

Create a file ending with .demo.ts in your project directory. For example, example.demo.ts:

import { group, demo, ask, say } from 'demoscript';

export default group('My Example Demos', 

  demo('Ask user to write', () => {
    const name = ask('What is your name?').read(String);
    const age = ask('What is your age?').read(parseInt);
    const yob = new Date().getFullYear() - age;
    say(`Hello, ${name}! You were born between ${yob - 1} and ${yob}.`);
  }),

  demo('Ask user to choose', () => {
    const numChoice = ask('Choose a number:').options(
      { label: 'One', value: 1 },
      { label: 'Two', value: 2 },
      { label: 'Three', value: 3 }
    );
    say(`You chose ${numChoice}.`);
  }),

  demo('Ask user to confirm', () => {
    const confirmed = ask('Are you sure?').confirm();
    say(confirmed ? 'You are sure!' : 'You are not sure!');
  })

);

NOTE: DemoScript looks only for default exports in .demo.ts files. You can export either a single demo or a group of demos. If you want to use named exports, be sure to import them in another .demo.ts file and export default group of those demos.
