pull-recvfrom

[reqshark]

pull-recvfrom for doing unix datagrams like IPC on steroids:

• address format for unix datagrams is a pathname
• ordered and reliable delivery of udp packets on the same box
• often orders of magnitude better latency and throughput versus ip stack or tcp
• communication between applications is limited to the same host machine (osx/linux kernel)

recvfrom in conjunction with sendto gives us a useful advantage over node-unix-dgram, because either the size of user buffers (in the case of sendto) or a number passed to recvfrom automatically reconfigures arbitrarily low max buf size system limits.

one call to kernel's setsockopt() adjusts unix datagram maximums for linux and osx. with sendto you dont have to think about that because we set socket option SO_SNDBUF, raising the send limit size up to the size of whatever node buffer you pass 🍻

yo try that:

var pullfrom = require('pull-recvfrom')
var sockname = '/tmp/ayyyyy'
var pull = require('pull-stream')

pull(
  pullfrom(sockname, require('recvfrom')), // pass address and recvfrom to pullfrom()
  pull.drain(log)
)
function log(buf){
  console.log(buf+'')
}

var sendto = require('sendto')
setInterval(sendto, 500, sockname, Buffer('hello from sendto'))
