CodersRank Skills Chart Widget is a web component that allows you easily integrate nice looking skills chart from your CodersRank profile to your personal website:

Install from NPM

Widget script available through NPM:

npm i @codersrank/skills-chart --save

After installation you need to import and register web component:

import CodersRankSkillsChart from '@codersrank/skills-chart';

// register web component as <codersrank-skills-chart> element
window.customElements.define('codersrank-skills-chart', CodersRankSkillsChart);

Install from CDN

Widget can also be downloaded or linked directly from CDN:

<!-- replace x.x.x with actual version -->
<script src="https://unpkg.com/@codersrank/skills-chart@x.x.x/codersrank-skills-chart.min.js"></script>

In this case it is not required to register web component, it is already registered as <codersrank-skills-chart> element.

Usage

As it is a web component the usage is pretty simple, just add widget HTML tag with your CodersRank username

<codersrank-skills-chart username="YOUR_USERNAME"></codersrank-skills-chart>

Styling

It is possible to customize widget colors with CSS Custom Properties (CSS Variables) by setting them directly on the widget element with style attribute or in CSS.

There are following CSS Custom Properties are available:

Property	Value
--font-family	Open Sans, Helvetica Neue, Helvetica, Arial, sans-serif
--svg-width	100%
--svg-height	auto
--axis-bg-color	rgba(0, 0, 0, 0.35)
--hidden-area-color	#ddd
--label-text-color	inherit
--label-font-size	10px
--label-font-weight	500
--label-white-space	nowrap
--legend-text-color	inherit
--legend-disabled-text-color	#ccc
--legend-font-size	14px
--preloader-color	#72a0a8
--tooltip-font-size	12px
--tooltip-total-font-size	16px
--tooltip-total-font-weight	bold
--other-skills-area-color	#bbb
--chart-bg-color	transparent
--chart-border-radius	0px
--branding-text-color	inherit

For example, to change legend text color to red and font-size to 12px, add this to CSS stylesheet:

codersrank-skills-chart {
  --legend-text-color: red;
  --legend-font-size: 12px;
}

Events

Widget element supports the following events:

Name	Description	Detail
error	Will be fired on data request error	`event.detail` will contain an error object
data	Will be fired right after data request	`event.detail` will contain an object with `highest` and `scores` properties. `highest` object contains information about when user had the highest score `scores` array contains information about skills scores by dates
render	Will be fired right after chart rendered to DOM

For example:

<codersrank-skills-chart id="skills-chart" skils="..."></codersrank-skills-chart>

function onData(event) {
  const highest = event.detail.highest;
  console.log(`Highest score was ${highest.score} on ${highest.date}`);
}
document.querySelector('#skills-chart').addEventListener('data', onData);

Use As Image

It is also possible to insert Skills Chart as an image. It is useful in places where you can't integrate web component, or for example on your GitHub profile README.md page.

Image URL is the following:

https://cr-skills-chart-widget.azurewebsites.net/api/api?username=YOUR_USERNAME

It accepts query parameters:

Name	Type	Default	Description
username	string		Your CodersRank username
skills	string		Specify skills to display in chart (comma separated), for example ?skills=JavaScript,TypeScript
width	number	640	Render width of chart's SVG element. Ideally should match actual chart width

show-other-skills	boolean	false	Group skills not specified in skills property under the "Other" chart area
bg	string	#fff	Chart background image

For example:

<img
  src="https://cr-skills-chart-widget.azurewebsites.net/api/api?username=YOUR_USERNAME&skills=JavaScript,TypeScript&show-other-skills=true"
/>

Live example:

<img
  src="https://cr-skills-chart-widget.azurewebsites.net/api/api?username=nolimits4web&skills=Vue,C%2B%2B,C%23,SCSS,Svelte&width=820"
/>
