cli-ux

What is cli-ux?

The cli-ux npm package provides a set of utilities for building command-line interfaces (CLIs). It offers features such as progress bars, spinners, prompts, and table formatting to enhance the user experience of CLI applications.

What are cli-ux's main functionalities?

Progress Bar

This feature allows you to display a progress bar in the terminal. The code sample demonstrates how to create and update a progress bar that increments by 5% every 100 milliseconds until it reaches 100%.

const cli = require('cli-ux');

const progress = cli.progress({ format: 'progress [{bar}] {percentage}% | ETA: {eta}s' });
progress.start(100, 0);

let value = 0;
const interval = setInterval(() => {
  value += 5;
  progress.update(value);
  if (value >= 100) {
    clearInterval(interval);
    progress.stop();
  }
}, 100);

Spinner

This feature provides a spinner to indicate ongoing processes. The code sample shows how to start a spinner with a message and stop it after 3 seconds with a 'done' message.

const cli = require('cli-ux');

cli.action.start('Processing');
setTimeout(() => {
  cli.action.stop('done');
}, 3000);

Prompt

This feature allows you to prompt the user for input. The code sample demonstrates how to ask the user for their name and then greet them with the provided input.

const cli = require('cli-ux');

(async () => {
  const name = await cli.prompt('What is your name?');
  console.log(`Hello, ${name}!`);
})();

Table

This feature allows you to display data in a table format. The code sample shows how to create a table with two columns: 'name' and 'age', and display two rows of data.

const cli = require('cli-ux');

const data = [
  { name: 'John', age: 30 },
  { name: 'Jane', age: 25 }
];
cli.table(data, {
  name: {
    minWidth: 7
  },
  age: {
    header: 'Age'
  }
});
