Usage

const { Spinnr, patterns } = require("spinnr");

const spinner = new Spinnr();

// Setting text
spinner.set_text("Loading...");

// Starting the spinner
spinner.start();

// Stopping the spinner after 2 seconds
setTimeout(() => {
	spinner.stop();
}, 2000);

Feautures

• Fully customizable ( literally )
• Plugin expandable
• Very light
• Can be dependency-free if colours removed
• Can work well with other libraries like kleur

Example

const { Spinr, patterns } = require("spinr");

const kleur = require("kleur");

const spinner = new Spinr();

// Text to show
spinner.set_text("Loading...");
// How long each pattern character takes
spinner.set_interval(75);
// Setting a pattern for the spinner
spinner.set_pattern(patterns.Ladder);
// Customizing the loading pattern (must be a function)
spinner.set_loading_edit(kleur.gray);
// Customizing the text to show (must be a function)
spinner.set_text_edit(kleur.bold().red);
// not deleting the line after finishing
spinner.set_delete(false);
// How long should the spinner wait before stopping
spinner.set_waiting_timeout(1000);
// what to show instead of the spinner pattern if it was stopped
spinner.set_done_flag("✔");

// Starting
spinner.start();

setTimeout(() => {
	spinner.set_text("Initializing Cold Blood...");
}, 1000);
setTimeout(() => {
	spinner.set_text("Calling Soldiers...");
}, 1000);
setTimeout(() => {
	spinner.set_text("Preparing Trucks...");
}, 1000);
setTimeout(() => {
	spinner.set_text("Dropping Soldiers...");
}, 1000);
setTimeout(() => {
	spinner.set_text("Cold Blood Operation Started");
	spinner.stop();
}, 5000);

Documentation

• Setting Text

  Setting the text to show

  const spinner = new Spinnr();
  spinner.set_text(text);

  text (String) : the text you wanna show

• Setting Interval

  How long each pattern character takes

  const spinner = new Spinnr();
  spinner.set_interval(interval);

  interval (Number) : the time each pattern character takes in ms

• Setting Pattern

  the spinner pattern

  const { Spinnr, patterns } = require("spinnr");
  
  const spinner = new Spinnr();
  const pattern = patterns.Bar;
  
  spinner.set_patterns(pattern);

  pattern (Array) : a pattern for the spinner

  Using patterns is recommended

• Setting Delete

  Choosing if the spinner is going to be deleted after it is done

  const spinner = new Spinnr();
  spinner.set_delete(true);

  del (Bool) : the option to delete

  if specificied the spinner will be deleted for the line and will live a blank line, if not nothing will happen

• Setting Waiting Timeout

  Specifiying the time the spinner will take to break when it's done

  const spinner = new Spinnr();
  spinner.set_waiting_timeout(1000); // 1s

  waiting_timeout (Number) : the timeout duration in ms

  if can accept 0 which means the spinner won't wait

• Setting the finishing text

  Setting up the text that will be shown instead of the pattern when the loading is done

  won't work if waiting_timeout is 0

  const spinner = new Spinnr();
  spinner.set_done_flag("✔");

  flag (Text) : the flag to show

  the flag is also affected by set_loading_edit

• Customizing Loading Spinner

  Customizing the loading spinner

  const kleur = require("kleur");
  const spinner = new Spinnr();
  
  spinner.set_loading_edit(kleur.bold().red);

  edit (Function) : the function to customize loading spinner

  It calls the edit on the loading pattern so that it can be customized.

  in the example above the loading pattern is normally black and has normal styles but once we added the set_loading_edit function, it'll show up in a red colour with bold style

  using kleur is recommended

• Customizing the text

  Customizing the shown text

  const kleur = require("kleur");
  const spinner = new Spinnr();
  
  spinner.set_text_edit(kleur.underline().green);

  edit (Function) : the function to customize the text

  It calls the edit on the text so that it can be customized.

  in the example above the text is normally black and has normal styles but once we added the set_text_edit function, it'll show up in a green colour with a line under

  using kleur is recommended
