Loading visualization for node.js CLI
A simple loading visualizer.
Example from example_bar.js:
const noading = require('./noading.js');
var config = {
val : 0,
max : 10,
litChar : '▓▒',
unlitChar : '░░',
len : 20,
litColor : 'red',
unlitColor : 'blue',
textColor : 'blue',
interval : 500
};
var n = new noading.bar(config);
n.start();
setInterval(function(){
n.val += 1;
}, 1000);
// Result:
// ▓▒▓▒▓▒▓▒▓▒▓▒▓▒▓▒▓▒▓▒▓▒▓▒▓▒▓▒▓▒▓▒▓▒▓▒▓▒▓▒ | 100%Create a noading bar with noading.bar() and a config object, then bar.start() to trigger the automatic update. Updating val will change the current progress of the bar. The bar can also be manually updated by calling bar.update() instead of start.
Depending on you terminal, noading can display visuals in various colors using chalk. This can be done by passing in either keywords ('blue') or hex codes ('#0000FF') in a noading config object. Chalk should automatically fallback if the active terminal does not support a certain color range. See the chalk docs for more details.
Below are the configs for the current loading bar types:
