deno progress

Usage

First we create a Progressbar, giving it a fmt string and options || total,
telling it when it will be considered complete. then we will do tick()

import Progressbar from "https://deno.land/x/deno_progress@<version>/mod.ts";

const bar = new Progressbar("|:bar|", { total: 100, width: 50 });
const id = setInterval(() => {
    bar.tick(2);
    if (bar.complete === true) {
        clearInterval(id);
    }
}, 100);

Options

• curr current completed index
• total total number of ticks to complete
• width the displayed width of the progress bar defaulting to total
• head head character defaulting to complete character
• complete completion character defaulting to “█”
• incomplete incomplete character defaulting to “░”
• renderThrottle minimum time between updates in milliseconds defaulting to 16
• callback optional function to call when the progress bar completes
• clear will clear the progress bar upon termination

Mehods:

• tick tick the progress bar with the given length and optional tokens
• render render the progress bar with optional tokens and optional force
• interrupt interrupt the progress bar and write a message above it.
• terminate terminates the progress bar

Tokens:

• :bar the progress bar itself
• :current current tick number
• :total total ticks
• :elapsed time elapsed in seconds
• :percent completion percentage
• :eta eta in seconds
• :rate rate of ticks per second

Custom Tokens

You can define custom tokens by adding

{ "name": value }

object parameter to tick() method

import { Progressbar } from "https://deno.land/x/deno_progress@<version>/mod.ts";
const bar = new Progressbar(":current: :token1 :token2", { total: 3 });

const bar = new Progressbar(":current: :token1 :token2", { total: 3 });
bar.tick({
    token1: "Hello",
    token2: "World!\n",
});

The above example would result in the result output below:

1: Hello World!

Examples

a simple example

import { Progressbar } from "https://deno.land/x/deno_progress@<version>/mod.ts";

const bar = new Progressbar("  :title |:bar| eta: :eta :percent", {
    total: 100,
});

const id = setInterval(() => {
    bar.tick(1, { title: "progress " });
    if (bar.complete === true) {
        clearInterval(id);
    }
}, 50);
