Data URIs

By  on  

We're all familiar with traditional URI protocols like https, http, ftp, and file, but data URIs have become a large part of our online strategy. We can use them to display images, the Mac camera and webcams, and more. But what if we simply want to use a data URI to convey basic data?

Typing a data URI shouldn't be difficult, and it isn't. As someone that works on the Firefox DevTools Debugger, I'm often typing out data URIs to illustrate problems. The format is:

data:text/html,<body class="blah"></body>

We're all so ingrained to use protocol://subdomain.domain.tld addresses that data URIs look foreign...but they require the least amount of resources to express content!
