In today's fast-paced world, keeping an eye on our sleep and readiness scores can greatly impact our overall well-being. The Oura Ring provides valuable data on sleep quality, readiness, and more. In this guide, we'll explore how to build a Sleep and Readiness Dashboard using the Oura API, a library written primary for Deno, a next-generation JavaScript Runtime. We'll create a project that fetches Oura data and with Deno Fresh visualizes your sleep and readiness scores over the past 30 days.

Template literals, introduced in ECMAScript 6 (ES6), offer a powerful way to work with strings in JavaScript. They allow for easy interpolation of variables, expressions, and even multiline strings.
