NodeJS

Node.js® is a platform built on Chrome's JavaScript runtime for easily building fast, scalable network applications. Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, perfect for data-intensive real-time applications that run across distributed devices.

Prerequesites

• Requires Python 2.7 installed as described in Python Altinstall
• git and g++

yum -y install git gcc-c++

Install

mkdir -p /var/git
cd /var/git
RELEASE=$(curl -s http://nodejs.org/download/ |grep Current\ version |awk -F"[><]" '{print $5}')
git clone https://github.com/joyent/node.git
cd /var/git/node
git reset --hard
git checkout $RELEASE
export PYTHON=/usr/local/bin/python2.7
$PYTHON ./configure
make
make install

Updating

RELEASE=$(curl -s http://nodejs.org/download/ |grep Current\ version |awk -F"[><]" '{print $5}')
cd /var/git/node
git reset --hard
git pull origin $RELEASE-release

On SME 9, you can install a reasonably recent version of NodeJS from the EPEL repository:

• Add the epel repository to the configuration db using the SME 9 instructions from Epel
• Update the yum configuration file using

signal-event yum-modify

• Install NodeJS

yum --enablerepo=epel install nodejs

This will install nodejs plus c-ares19, http-parser, libuv and v8 from the epel repo, plus libicu from the base repo.

Updating

• Update using

yum --enablerepo=epel update nodejs c-ares19 http-parser libuv v8

• NodeJS updates are released every 3 - 12 weeks; check for updates regularly.

Test

node -v
