Observable-hooks.js.org Test Results

Observable-hooks.js.org Mobile Performance: 80/100
Quick overview:
Opportunities
These suggestions can help your page load faster. They don't directly affect the Performance score.
Remove unused JavaScript. Potential savings of 83 KiB
Remove unused JavaScript to reduce bytes consumed by network activity. Learn more.
Serve images in next-gen formats. Potential savings of 50 KiB
Image formats like JPEG 2000, JPEG XR, and WebP often provide better compression than PNG or JPEG, which means faster downloads and less data consumption. Learn more.
Avoid serving legacy JavaScript to modern browsers. Potential savings of 44 KiB
Polyfills and transforms enable legacy browsers to use new JavaScript features. However, many aren't necessary for modern browsers. For your bundled JavaScript, adopt a modern script deployment strategy using module/nomodule feature detection to reduce the amount of code shipped to modern browsers, while retaining support for legacy browsers.

Diagnostics
More information about the performance of your application. These numbers don't directly affect the Performance score.
Serve static assets with an efficient cache policy
10 resources found
A long cache lifetime can speed up repeat visits to your page. Learn more.
Largest Contentful Paint element
1 element found
This is the largest contentful element painted within the viewport. Learn More
Avoid long main-thread tasks
5 long tasks found
Lists the longest tasks on the main thread, useful for identifying worst contributors to input delay. Learn more
Avoid large layout shifts
4 elements found
These DOM elements contribute most to the CLS of the page.
Keep request counts low and transfer sizes small
33 requests • 297 KiB
To set budgets for the quantity and size of page resources, add a budget.json file. Learn more.
Avoid chaining critical requests
1 chain found
The Critical Request Chains below show you what resources are loaded with a high priority. Consider reducing the length of chains, reducing the download size of resources, or deferring the download of unnecessary resources to improve page load. Learn more.

Observable-hooks.js.org Mobile SEO: 75/100
Quick overview:
Mobile Friendly
Make sure your pages are mobile friendly so users don’t have to pinch or zoom in order to read the content pages. Learn more.
Tap targets are not sized appropriately
Interactive elements like buttons and links should be large enough (48x48px), and have enough space around them, to be easy enough to tap without overlapping onto other elements. Learn more. Tap targets are too small because there's no viewport meta tag optimized for mobile screens
Document doesn't use legible font sizes
Font sizes less than 12px are too small to be legible and require mobile visitors to “pinch to zoom” in order to read. Strive to have >60% of page text ≥12px. Learn more. Text is illegible because there's no viewport meta tag optimized for mobile screens.
Does not have a `<meta name="viewport">` tag with `width` or `initial-scale`
Add a `<meta name="viewport">` tag to optimize your app for mobile screens. Learn more. No `<meta name="viewport">` tag found

Observable-hooks.js.org Mobile Best Practices: 93/100
Quick overview:
Trust and Safety
Does not use HTTPS
1 insecure request found
All sites should be protected with HTTPS, even ones that don't handle sensitive data. This includes avoiding mixed content, where some resources are loaded over HTTP despite the initial request being servedover HTTPS. HTTPS prevents intruders from tampering with or passively listening in on the communications between your app and your users, and is a prerequisite for HTTP/2 and many new web platform APIs. Learn more.

Installable
Does not use HTTPS
1 insecure request found
All sites should be protected with HTTPS, even ones that don't handle sensitive data.

HTTPS prevents intruders from tampering with or passively listening in on the communications between your app and your users, and is a prerequisite for HTTP/2 and many new web platform APIs. Learn more.
Web app manifest does not meet the installability requirements
Browsers can proactively prompt users to add your app to their homescreen, which can lead to higher engagement. Learn more. Failures: Manifest's `display` value is not one of: minimal-ui | fullscreen | standalone, Manifest does not have `short_name`.
PWA Optimized
Manifest doesn't have a maskable icon
A maskable icon ensures that the image fills the entire shape without being letterboxed when installing the app on a device. Learn more.
Does not set a theme color for the address bar.
The browser address bar can be themed to match your site. Learn more. Failures: Manifest does not have `theme_color`.
Is not configured for a custom splash screen
A themed splash screen ensures a high-quality experience when users launch your app from their homescreens. Learn more. Failures: Manifest does not have a PNG icon of at least 512px, Manifest does not have `background_color`, Manifest does not have `theme_color`.
Does not have a `<meta name="viewport">` tag with `width` or `initial-scale`
