nanospinner

What is nanospinner?

The nanospinner npm package is a lightweight and simple terminal spinner for Node.js applications. It is used to display a spinner in the terminal to indicate that a process is ongoing, which can enhance the user experience by providing visual feedback during long-running operations.

What are nanospinner's main functionalities?

Basic Spinner

This feature allows you to create a basic spinner that starts immediately and stops after a specified duration, indicating success.

const { createSpinner } = require('nanospinner');

const spinner = createSpinner('Loading...').start();

setTimeout(() => {
  spinner.success({ text: 'Done!' });
}, 2000);

Custom Spinner Styles

This feature allows you to customize the spinner style. In this example, the 'dots' style is used, and the spinner indicates failure after a specified duration.

const { createSpinner } = require('nanospinner');

const spinner = createSpinner('Loading...', { spinner: 'dots' }).start();

setTimeout(() => {
  spinner.error({ text: 'Failed!' });
}, 2000);

Spinner with Custom Interval

This feature allows you to set a custom interval for the spinner's animation. The spinner text is updated midway through the process, and it indicates success at the end.

const { createSpinner } = require('nanospinner');

const spinner = createSpinner('Loading...', { interval: 100 }).start();

setTimeout(() => {
  spinner.update({ text: 'Almost there...' });
}, 1000);

setTimeout(() => {
  spinner.success({ text: 'Done!' });
}, 2000);
