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.


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 🙏

@antv/ava is the core JS package of AVA, which contains four main modules:

  • data (Data Processing): Data Processing Module. Used for statistical analysis and processing of datasets.
  • insight (Auto Insight): Automatic Insights Module. Automatically discover data insights from multi-dimensional data.
  • ckb (Chart Knowledge Base): Chart Knowledge Base Module. Based on empirically derived knowledge and observations about the various fundamentals of visualization and charts, it is the cornerstone of intelligent chart recommendations.
  • advisor (Chart Recommendation): Chart Recommendation Module. Recommend chart types and specific chart detail settings based on data and analysis needs, as well as chart optimization for existing charts.

Installation and Usage

Installation can be done via npm or the yarn package manager.

# npm
$ npm install @antv/ava --save

# yarn
$ yarn add @antv/ava

The following is a practical example of how the four main modules of @antv/ava can be used:

import { DataFrame, getInsights, ckb, Advisor } from '@antv/ava';

// input data
const data = [
  { price: 38, type: 'A' },
  { price: 52, type: 'B' },
  { price: 61, type: 'C' },
  { price: 145, type: 'D' },
  { price: 49, type: 'E' },

// 1. Data Processing Module
const df = new DataFrame(data);
const dataInfo =;

// 2. Automatic Insights Module
const { insights } = getInsights(data);

// 3. Chart Knowledge Base Module
const myCkb = ckb();

// 4. Chart Advisor
const chartAdvisor = new Advisor();
// recommend charts and give optimization suggestions based on input data
const results = chartAdvisor.advise({ data });
