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:

Widget script available through NPM:

npm i @codersrank/skills-chart --save

After installation you need to import and register web component:

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