RunKit + 
Try any Node.js package right in your browser
This is a playground to test code. It runs a full Node.js environment and already has all of npm’s 1,000,000+ packages pre-installed, including fileiojs. Try it out:
// Sample for tonic : https://tonicdev.com/npm/fileiojs
var fileiojs = require("fileiojs");
var manager = fileiojs.manager("Text", "txt", "// Very impressive file")
// Start of my wonderfull project
manager.createFile("wonderful.txt")
.then(function(){
// Oh my god, the file contains a typo. I should fix !
return manager.renameFile("wonderful.txt", "wonderfull.txt");
}).then(function(){
console.log("Ready for a wonderfull project !");
});
