Resolving the script tag type attribute hash prepending issue with Cloudflare

If your script HTML tag has the type attribute prepended with a hash, like <script type="ea10e272b0a1989fb2f3aa4e-text/javascript">...</script> and you’re using Cloudflare services, then the root cause is the Cloudflare Rocket Loader, a feature of Cloudflare that optimizes the loading of JavaScript resources on your web pages.

Rocket Loader modifies the type attribute of script tags for website loading optimization by deferring the loading of JavaScript until after rendering. This modification can sometimes cause issues with HTML validation and Content Security Policy (CSP) headers.

Cloudflare Rocket Loader adds an argument “type” into the script tag and causing issues with the W3C validator due to the “subtype missing” error.

Convert SVG to image in browser: PNG, JPEG, WebP

To convert SVG to PNG, JPG, or WebP WebP is a modern raster graphics file format created by Google to provide more powerful lossless and lossy compression for images on the web. It is designed to replace the JPEG, PNG, and GIF file formats, and it supports animation and alpha transparency. WebP images are less in size than popular formats such as PNG and JPEG, which might result in faster website load times., you can use the DOM API to create an object URL from the SVG code, load it into an image element, and then write that image to a Canvas. Finally, you can use the toDataURL() method to convert the Canvas to a base64 encoded PNG image.

Add a badge to the browser tab favicon using JavaScript

Adding a badge to the favicon using JavaScript can be done by updating the image specified by the <link /> element with a new icon image.

This method involves JavaScript and creating an in-memory canvas element, applying the favicon image, drawing the badge shape and text on top, and then updating the <link /> element’s href attribute with the final composite of the canvas element’s image data as a Base64 encoded string.
