LWC Focus-Trapping Modal

Using SLDS classes, build a modal Lightning Web Component that has focus-trapping for accessiblity.

Notes: The shadowdom presents some challenges with creating focus-trapping within modals. Making creating a reusable component tricky. So instead we can create a modal utility file with all our methods to keep things as DRY as possible.

const stdTimezoneOffset = (date) => {
    const jan = new Date(date.getFullYear(), 0, 1);
    const jul = new Date(date.getFullYear(), 6, 1);
    return Math.max(jan.getTimezoneOffset(), jul.getTimezoneOffset());
};

const isDstObserved = (date) => date.getTimezoneOffset() < stdTimezoneOffset(date);

const offset = start.getTimezoneOffset();
const start = new Date(start.getTime() - (offset*60*1000));

LWC/Apex User Debug Mode Console Logs

Using the Debug Mode setting in the running User to send debug console logs to the Inspector for Lightning Web Components.

If you need to override the debug behavior, you can change the userDebugMode sessionStorage property to 'true'. You might need to do this to get logs for Guest users that do not have a Debug Mode.

SEO and Social Media Meta Tag Setup for Experience Cloud Sites

About Meta Tags

Meta Tags are HTML tags hidden within the header of a web page. These tags contain information about your page. For example: a title, a brief description, and images.

When a social media channel receives a URL, behind the scenes it goes to this URL to try and gather information about this page. While most channels do their best to figure out what title or image to display from the page itself, we can be more explicit by setting up meta tags. If these meta tags are present, the channel will use them first.
