Nodejs equivalent of Web Javascript URL.createObjectURL(new Blob(["some string code"]))

[DrLightman]

Hello,

I need to convert for my nodejs project what I found in a javascript environment for web code:

var foo = window.URL.createObjectURL(new Blob([" ..."]) );

Searched but with no luck at all.

Any idea?

Thank you.

here's a quick-and-dirty shell-script which calls nodejs to convert an
image into a datauri (see screenshot for example usage). you can
probably edit it to suit your needs.

```shell
shImageToDataUri() {(set -e
# this function will convert the image $FILE to a data-uri string
# example usage:
# $ curl -O https://cdn0.iconfinder.com/data/icons/iconico-3/1024/63.png
# $ shImageToDataUri 63.png
case "$1" in
http://*)
FILE=/tmp/shImageToDataUri.png
curl -#Lf "$1" > "$FILE"
;;

FILE=/tmp/shImageToDataUri.png
curl -#Lf "$1" > "$FILE"

FILE="$1"

node -e "

/*jslint

'use strict';
console.log('data:image/' +
require('path').extname('$FILE').slice(1) +
';base64,' +
require('fs').readFileSync('$FILE').toString('base64'));
// </script>
"
)}
```
