Is there a sprintf equivalent for node.js
Printfnode.jsPrintf Problem Overview
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
Printf Solutions
Solution 1 - Printf
There is now printf-like support in util.format().
Example:
util.format('hello %s', 'world');
// Returns: 'hello world'
Solution 2 - Printf
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
Solution 3 - Printf
Here is the javascript version of sprintf:
Solution 4 - Printf
console.log works fine.
console.log('%d hours', 4); // 4 hours
console.log('The %2$s contains %1$d monkeys', 4, 'tree'); // The tree contains 4 monkeys
Solution 5 - Printf
Use locutus
As of now, there is a package that translate functions of other languages to Javascript such as php, python, ruby etc.
const sprintf = require("locutus/php/strings/sprintf")
const data = sprintf("%01.3f", 2);
console.log(data)
//output: 2.000
