This is a playground to test JavaScript. It runs a completely standard copy of Node.js on a virtual server created just for you. Every one of npm’s 300,000+ packages are pre-installed, so try it out:
const path = require('path');
const fs = require('fs');
// From http://sagegerard.com/slick-node-js-file-navigation/
function mount(home) {
function vantage(...args) {
return path.resolve(home, ...args);
}
vantage.cd = function (...args) {
return mount(vantage(...args));
};
vantage.walk = function* () {
for (const basename of fs.readdirSync(home)) {
const abspath = path.join(home, basename);
const stat = fs.statSync(abspath);
const nest = yield [abspath, basename, stat];
if (stat.isDirectory() && (nest === undefined || nest === true)) {
yield* vantage.cd(abspath).walk();
}
}
};
vantage.ls = function* () {
const it = vantage.walk();
let { done, value } = it.next(false);
while (!done) {
yield value;
({ done, value } = it.next(false));
}
};
return vantage;
}
const root = mount('/');
console.log(Array.from(root.ls()).map(([,bn]) => bn))
