NPM Proxy Cache - save pulling from the internet all the time...

npm-proxy-cache.txt

# For Ubuntu 16.04 vm guest where I code, windows host
# prefer not to have system installed node/go/erlang/elixir/etc
# thanks http://willcodefor.beer/setup-your-own-npm-cache-server/ for the idea!

sudo useradd -m -c "NPM-Proxy-Cache" npmpc
sudo su npmpc

npm config set proxy http://127.0.0.1:6060/  
npm config set https-proxy http://127.0.0.1:6060/  
npm config set strict-ssl false

# done, npm now uses the cache and when the vm restarts, the proxy is restarted.
# the proxy is also accessible from other vms as long as networking is configured etc
# can also use the proxy from windows host if I wanted to

z is it faster though?

so acutally measured with and without npm-proxy-cache and seems to be about the same..
of course uses less data which is good, as never able to know if others in the house
are streaming youtube/netflix etc and will help with 4G data. keep it for now...

might also assist with avoiding the common "callback called more than once" error - especially with the CI/CD setup
