Is there a sprintf equivalent for node.js

Question

Looking to do output formatting (sprintf type functionality) in node.js, but before I write it myself I was wondering if there's something similar built-in (I've trawled the docs to no avail) or if someone's already written a module.

Many thanks

Answer 1

There is now printf-like support in util.format().

Example:

util.format('hello %s', 'world'); // Returns: 'hello world' 

Answer 2

There are couple in the npm registry which are actual sprintf implementations since util.format has just a very basic support.

• sprintf (deprecated now)
• sprintf-js
• fast-printf
