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

Chart.js React

Tiny, written in TS, based on React hooks wrapper for Chart.js v4

codecov npm version

Why?

The main problem that the most popular package react-chartjs-2 was written many years ago has a bunch of legacy code and issues (in 90% of cases it does not work without the redraw = true flag).

The main idea was to completely rewrite code into modern React with hooks.

The second goal, add custom React tooltips for Chart.js

Version

The version format is X.Y.Z, where

  • X - is chart.js major version
  • Y - is chartjs-react major version
  • Z - is chartjs-react minor version

Current latest versions

  • 3.8.0 supports Chart.js version 3.9.1 and above

Examples

Bar chart on Chart.js v3 (date-fns)

import {
  BarController,
  LinearScale,
  BarElement,
  TimeScale,
  Tooltip,
} from 'chart.js';
import 'chartjs-adapter-date-fns';
import { enUS } from 'date-fns/locale';
import { ReactChart } from 'chartjs-react';

// Register modules,
// this example for time scale and linear scale
ReactChart.register(BarController, LinearScale, BarElement, TimeScale, Tooltip);

// options of chart similar to v2 with a few changes
// https://www.chartjs.org/docs/next/getting-started/v3-migration/
const chartOption = {
  scales: {
    x: {
      type: 'time',
      adapters: {
        date: enUS,
      },
    },
    y: {
      type: 'linear',
    },
  },
};

// data of chart similar to v2, check the migration guide
const chartData = {};

const BarChart = () => {
  return (
    <ReactChart
      type="bar"
      data={chartData}
      options={chartOption}
      height={400}
    />
  );
};

Get the chart instance

import { Chart } from 'chart.js';

onEvent = () => {
  const myChartInstance = Chart.getChart('unique-chart-id');
  // Do your stuff with the chart instance
  // Note: the chart should be mounted
};

const BarChart = () => {
  return (
    <ReactChart
      id="unique-chart-id"
      type="bar"
      data={chartData}
      options={chartOption}
      height={400}
    />
  );
};

TODO

  • Added chart tooltip as children (after release v3)
