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 🙏

Readme

pure-color-thief-node

Pure javascript version of color thief reimplementation for Node.js.

The original color thief project relies on the browser Canvas object to extract pixels from images. It does not work well in Node.js environment because the Canvas object does not natively exist in Node.js.

Another project, Color Thief Node, however, relies on the node-canvas library to simulate a Canvas object in Node.js environment. It involves unnecessary gyp build. Is behaves badly when a pre-build version of node-canvas is provided for your runtime, expecially when you need to deploy your project with docker (your image usually do not provide full gyp-build env).

However, canvas is only used to get the pixel information of the image, which is very inefficient for Node environment. We can use a simpler way to get the pixel color information.

Here comes pure-color-thief-node! 100% Javascript, gyp freeeeeeeeeeeeee ! ! !

Installation

npm i pure-color-thief-node

or

yarn add pure-color-thief-node

Usage

Get the Dominant Color from an Image

const colorThief = require('pure-color-thief-node');

const img = new colorThief();
img.loadImage('./cover.jpg').then(()=>{
    console.log(img.getColor());
});

Build a Color Palette from an Image

const colorThief = require('pure-color-thief-node');

const img = new colorThief();
img.loadImage('./cover.jpg').then(()=>{
  console.log(img);
  // 5 for palette color count, min 3
  console.log(img.getColorPalette(5));
});

Get the Dominant Color from an Image Buffer

const colorThief = require('pure-color-thief-node');
const fs = require('fs');
const img = new colorThief();
img.loadImage(fs.readFileSync('./cover.jpg'), 'image/jpeg').then(()=>{
  console.log(img);
  console.log(img.getColor());
});

Enjoy ✔️
