NPM proxy cache for CI

Same like bower, it might happen that you need to build things not only locally but also in some sort of CI. Deploying a npm proxy cache is fairly easy. Installation I suggest to add a specific user for this: useradd -m -d /var/cache/npm -s /bin/false npm Some neccessary packages: apt-get install nodejs You probably want to fetch the latest packages. Now we install the cache: sudo -u npm /bin/bash cd npm install npm-proxy-cache Startup /etc/systemd/system/npm-proxy-cache.service [Unit] Description=npm proxy cache After=network.target After=syslog.target [Service] RuntimeDirectory=npm-proxy-cache PIDFile=/var/run/npm-proxy-cache/npm-proxy-cache.pid WorkingDirectory=/var/cache/npm ExecStart=/var/cache/npm/node_modules/npm-proxy-cache/bin/npm-proxy-cache -e -h %H Restart=always RestartSec=10 StandardOutput=syslog StandardError=syslog SyslogIdentifier=npm-proxy-cache User=npm Group=npm [Install] WantedBy=multi-user.target Client usage npm config set proxy http://npm-proxy-cache.example.com:8080 npm config set https-proxy http://npm-proxy-cache.example.com:8080 npm config set strict-ssl false
