When you need to set value to "UV_THREADPOOL_SIZE"?

• Libuv has a default thread pool size of 4, and uses a queue to manage access to the thread pool - the upshot is that if you have 5 long-running DB queries all going at the same time, one of them (and any other asynchronous action that relies on the thread pool) will be waiting for those queries to finish before they even get started.

• Note, however, that tuning UV_THREADPOOL_SIZE may make more sense for a standalone application like a CLI written in Node.js. If you are standing up a bunch of Node.js processes using the cluster module then I would be surprised if tuning UV_THREADPOOL_SIZE was particularly beneficial for you. But if your application resembles the web tooling benchmarks then tuning UV_THREADPOOL_SIZE may help with performance.

Configure Git to use a proxy

In Brief

You may need to configure a proxy server if you're having trouble cloning or fetching from a remote repository or getting an error like unable to access '...' Couldn't resolve host '...'.

Consider something like:

max-mapper

// warning you probably want `ssh-keygen -t ed25519` for most use cases. this method lacks secure prng and uses weak rsa
var keypair = require('keypair')
var forge = require('node-forge')

// generates new keypair (slow)
var pair = keypair()

// creates intermediate forge key object
var publicKey = forge.pki.publicKeyFromPem(pair.public)

rvagg

#!/bin/bash

# Note your /usr/local will need to be writable by the user running it,
# alternatively run it with `sudo`

hasxz=$(which xzcat)
os=$(uname | tr '[A-Z]' '[a-z]')
arch=$(uname -m)
targetdir="/usr/local/"
domain=nodejs.org
