The utility functions used by the OpenSauced Extension project can be found in src/utils. Each utility function serves a single purpose and is intended to be reusable across different parts of the project. The utilities are organized into domain-specific sub-directories within the utils folder, such as /utils/dom-utils for utilities related to manipulating the DOM.
| NOTE: This page is not meant to be an exhaustive list of all utility functions used in the project, but to highlight a few of the ones that may otherwise be esoteric. |

Added in PR #36, the function allows you to cache responses from API calls in local storage, reducing the number of network requests and improving performance. It takes a URL and optional options object as arguments, including an option to set the time in seconds before the cache expires and force a refresh. If there is a cached response that has not expired, it returns that instead of making another call. Otherwise, it makes a fetch request and caches the response if it meets certain criteria (status code 200 and content type JSON or text).
Added in PR #20, the function creates an HTML element of a specified tag name and with optional properties. The properties can include styles, which are applied to the element's inline style attribute. Other non-style properties are also supported and added to the created element using Object.assign(). Orginal implementation.
Added in PR #56, this function checks if the user is authenticated by retrieving a cookie from Chrome storage and verifying its validity. If the cookie does not exist or is invalid, it removes any saved authentication token from Chrome storage.
Added in PR 64, this function is used to observe changes in the DOM and trigger a callback function when changes occur. The function uses a MutationObserver to track changes in the document body, and checks if the page has fully loaded before executing the callback with any specified delay time.
