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 protodef. Try it out:
const ProtoDef = require('protodef').ProtoDef
const Serializer = require('protodef').Serializer
const Parser = require('protodef').Parser
// the protocol can be in a separate json file
const exampleProtocol = {
container: 'native',
varint: 'native',
byte: 'native',
bool: 'native',
switch: 'native',
entity_look: [
'container',
[
{
name: 'entityId',
type: 'varint'
},
{
name: 'yaw',
type: 'i8'
},
{
name: 'pitch',
type: 'i8'
},
{
name: 'onGround',
type: 'bool'
}
]
],
packet: [
'container',
[
{
name: 'name',
type: [
'mapper',
{
type: 'varint',
mappings: {
22: 'entity_look'
}
}
]
},
{
name: 'params',
type: [
'switch',
{
compareTo: 'name',
fields: {
entity_look: 'entity_look'
}
}
]
}
]
]
}
const proto = new ProtoDef()
proto.addTypes(exampleProtocol)
const parser = new Parser(proto, 'packet')
const serializer = new Serializer(proto, 'packet')
serializer.write({
name: 'entity_look',
params: {
entityId: 1,
yaw: 1,
pitch: 1,
onGround: true
}
})
serializer.pipe(parser)
parser.on('data', function (chunk) {
console.log(JSON.stringify(chunk, null, 2))
})

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
