Node.js

Asynchronous Javascript Framework
Node.js is a cross-platform Javascript runtime environment built on Chrome's V8 JavaScript engine. Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, especially for server-side and networking applications. npm, Nodes package ecosystem is the largest ecosystem of open source libraries in the world.

This appliance includes all the standard features in TurnKey Core, and on top of that:
- Node.js configurations:
- n Node Version Manager used to install the latest stable version of
Node. n supports updating Node to the latest version and switching between
multiple older versions:
# install latest stable node n stable # show all installable versions n list # install specific version n <version>
- Support for installing npm packages globally more securely
without root or sudo:
su node npm install -g package
- systemd PM2 service at /etc/systemd/system/pm2-node.service runs
node apps on boot.
pm2 is a production process manager that helps keep your node apps running, supports clustering and makes it easy to manage node apps:
# su node $ pm2 start --max-memory-restart 500M /opt/yourapp/app.js $ pm2 stop tklweb-cp $ pm2 list
- Default Nginx configuration template:
server { listen 0.0.0.0:80 default_server; set $nodeapp_port 8000; include /etc/nginx/include/nodejs-proxy; }
- npm bash tab-completion:
$ npm in<tab> info init install
- hundreds of node example apps:
$ ls /opt/node-examples express_example node-by-example nodejsbook.io.examples practicalnode
- Default web page / control panel at /opt/tklweb-cp is itself an example Node.js app built with express and jade templating.
- n Node Version Manager used to install the latest stable version of
Node. n supports updating Node to the latest version and switching between
multiple older versions:
- Bundled globally-installed Node.js packages:
- PM2: production process manager. Configured to start on boot as a systemd service.
- forever: a simple CLI tool for ensuring a node app runs continuously. Supports watching sources for changes and restarting app.
- node-inspector: a powerful debugger modeled after Chrome devtools.
- grunt: task runner that automates repetitive tasks like minifcation, compilation, unit testing and linting.
- bower: package manager for client-side browser dependencies
- nsp: Node Security Project package auditor. Audits dependencies
for known security vulnerabilities:
cd /opt/yournodeapp nsp audit-package
- Postfix MTA (bound to localhost) to allow sending of email (e.g., password recovery).
- Webmin modules for configuring Postfix.
