A modern bencode parser focused on speed and perfomance. It used recursive descent parser, a kind of top-down parsers.
// classic api
const decode = require('btparse')
// or you can use lazy parser
// const decode = require('btparse/lazy')
console.log(decode(torrent).info.name)
console.log(decode('d3:abcli13eee')) // {abc: [ 13 ]}nodejs 8.3.0 / windows 10 x64 / i5 4690

Parse and decode bencoded message.
opts.depth: Number
Max parse depth for objects; default = infinity, min = 1
const decode = require('btparse')
console.log(decode('d2:abi2e2:bbd2:ccleee', {depth: 1})) // {ab: 2, bb: Buffer.from('d2:cclee')}The main difference is that all buffers decoded into a strings on demand. Required nodejs 6+.
const decode = require('btparse/lazy')
// get prop
console.log(decode(torrent).info.name)
// check prop
console.log('name' in decode(torrent).info)
// get all keys / props
console.log(Reflect.ownKeys(decode(torrent)))MIT, (c) Dmitry Tsvettsikh, 2017+
