Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Getting started

To get started with this library, you need to install it and add it to your project.

Installation

# npm
npm install gifski-command --save

# yarn
yarn add gifski-command

Library Usage

API Reference available at https://pichillilorenzo.github.io/gifski-command/.

import * as path from 'path';
import {GifskiCommand} from 'gifski-command';
// or
const path = require('path');
const {GifskiCommand} = require('gifski-command');

const command = new GifskiCommand({
  output: path.join(__dirname, 'test', 'video.gif'),
  frames: [ path.join(__dirname, 'test', 'video.mp4.frame*.png') ],
  quality: 100
});
command.on('progress', progress => {
  console.log(progress);
});
const result = await command.run();

CLI Usage

  • <pattern> represents a glob pattern used to specify PNG frames used by gifski. Surround the glob pattern with quotes (example './test/**/*.png').
  • [options] are the same as the gifski CLI options.
Usage: gifski-command [options] <pattern>

Examples: 
  gifski-command -Q 100 -o './test/video.gif' './test/**/video.mp4.frame*.png'
  gifski-command -o - './test/**/video.mp4.frame*.png' > './test/video.gif'

Arguments:
  pattern                Glob pattern of PNG image files. Surround the glob pattern with quotes (example './test/**/*.png').

Options:
  -o, --output <a.gif>   Destination file to write to; "-" means stdout
  -r, --fps <num>        Frame rate of animation. This means the speed, as all frames are kept. [default: 20]
  --fast                 50% faster encoding, but 10% worse quality and larger file size
  --extra                50% slower encoding, but 1% better quality
  -Q, --quality <1-100>  Lower quality may give smaller file [default: 90]
  -W, --width <px>       Maximum width. By default anims are limited to about 800x600
  -H, --height <px>      Maximum height (stretches if the width is also set)
  --no-sort              Use files exactly in the order given, rather than sorted
  -q, --quiet            Do not display anything on standard output/console
  --repeat <num>         Number of times the animation is repeated (-1 none, 0 forever or <value> repetitions)
  -h, --help             display help for command

CLI Usage Example

The recommended way is to first export video as PNG frames. If you have ffmpeg installed, you can run in terminal:

ffmpeg -i ./test/video.mp4 ./test/video.mp4.frame%04d.png

and then make the GIF from the frames:

gifski-command -Q 100 -o './test/video.gif' './test/**/video.mp4.frame*.png'

This code snippet shows how to put into action gifski-command to convert video frames into a high quality GIF using the gifski encoder.
