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 krate. Try it out:
const Promise = require('bluebird')
const Krate = require('krate').configure({ Promise })
const container = new Krate.Container({ timeout: 5000 })
const define = container.define.bind(container)
const resolve = container.resolve.bind(container)
define('foo', () => 'FOO') // return a value
define('bar', () => Promise.resolve('BAR')) // return a promise
define('baz', (done) => done(null, 'BAZ')) // callback style
define('qux', (deferred) => deferred.resolve('QUX')) // using deferred
define({
'character/solo': () => ('Han Solo'),
'character/leia': () => ('Princess Leia'),
'character/vader': () => ('Darth Vader'),
'character/palpatine': () => ('Emperor Palpatine')
})
define('foofoo', 'foo as val', ({ val }) => val + val)
define('foobar', ['foo', 'bar as b'], ({ foo, b }) => foo + b)
define('barbaz', { bar: true, b: 'baz' }, ({ bar, b }) => bar + b)
define('characters', {
factory: (characters) => ( characters ),
depends: (memo, key, i) => {
const prefix = 'character/'
if(key.indexOf(prefix) !== 0) return memo
return memo.concat(`${key} as ${key.slice(prefix.length)}`)
}
})
define({
good: {
depends: 'characters',
factory: ({ characters }) => {
const { solo, leia } = characters
return { solo, leia }
}
},
evil: {
depends: 'characters',
factory: ({ characters }) => {
const { vader, palpatine } = characters
return { vader, palpatine }
}
}
})
resolve([
'foofoo',
'foobar',
'barbaz',
'good',
'evil'
]).then((everything) => {
console.log(everything)
})
// #=>
// foofoo: "FOOFOO"
// foobar: "FOOBAR"
// barbaz: "BARBAZ"
// good: {
// solo: "Han Solo",
// leia: "Princess Leia"
// }
// bad: {
// vader: "Darth Vader"
// palpatine: "Emperor Palpatine"
// }

require()any package directly from npm- use arrow functions, classes, template strings, and most of ES6
awaitany promise instead of using callbacks (example)- create your own embedded node.js snippets
