Remix Client Hints

Overview

This article provides an example of implementing theme switching and server dates using Epic Stack - Client Hints and Jacob Paris’ article as a reference. The example demonstrates how the server retrieves theme and time-zone hints on the first visit, stores them in cookies, and reloads the page for client-side usage. The approach aims to improve user experience by avoiding the flash of unstyled content on every page load.

Features

• Theme Switching: Implements theme switching based on the prefers-color-scheme media feature. It updates the theme cookie through a POST request to the /resources/theme route and either reloads the page or returns a JSON response.
• Time-Zone: Allows the server to understand the client’s time zone on initial page load. The server-side implementation uses the getHints(request).timeZone method to retrieve time zone information. For client-side usage, the useHints().timeZone method can be employed.
• UI Display: The App Demo displays the time zone in the user interface using the Intl.DateTimeFormat object created in the user’s time zone and preferred language.
