CodersRank Activity Widget

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

Install from NPM

The widget script available through NPM:

npm i @codersrank/activity --save

After installation you need to import and register web component:

import CodersRankActivity from '@codersrank/activity';

// register web component as <codersrank-activity> element
window.customElements.define('codersrank-activity', CodersRankActivity);

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/[email protected]/codersrank-activity.min.js"></script>

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

}

Events

Widget element supports the following events:

Name	Description	Detail

data	Will be fired right after data request	event.detail will contain an object with data and total properties. total property contains number of total activities data object contains information about activities by dates

For example:

<codersrank-activity id="activity" ...></codersrank-activity>

function onData(event) {
  const total = event.detail.total;
  console.log(`${total} activities in the last year`);
}
document.querySelector('#activity').addEventListener('data', onData);

Use As Image

It is also possible to insert Activity widget 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-ss-service.azurewebsites.net/api/ScreenShot?widget=activity&username=YOUR_USERNAME

It accepts all widget attributes as query string parameters, plus one extra parameter:

Name	Type	Default	Description
width	number	800	Width of widget element (generated image). Note that generated image has @2x pixel density, so the PNG image will be actually generated in @2x size from the one specified here
style	string		style attribute value (here you can specify all CSS variables)

For example:

<img
  src="https://cr-ss-service.azurewebsites.net/api/ScreenShot?widget=activity&username=YOUR_USERNAME&labels=true"
/>

Note that you need to URL Encode some of the characters, for example # should be %23 and #ff0 color should be specified as %23ff0 in query.
