A JavaScript code which can create a raw and signed transactions

Hi all,

I have created a tiny JavaScript code that encodes transaction data into raw transaction buffer and creates an Ed25519 signature to transfer (a.k.a. peer-to-peer transfer) testnet coins.

libra-peer_to_peer_transfer.js


const crypto = require('crypto');
const grpc = require('grpc');
const protoLoader = require('@grpc/proto-loader');
const protobufjs = require('protobufjs');
const ed25519 = require('ed25519');

const PROTO_DIR = __dirname + '/proto';

const privateKey = Buffer.from('fbcedfd8848bf097ca79a8248a26d929ebf7104c1fcc471a6c4fd87113798766', 'hex');

This is obviously a small test code which cannot be used in a production, but I hope it will help someone (especially who is trying to write a JS library) in a future.
