You can try to compile node.js. Something like this:
tce-load -wo make gcc compiletc openssl-dev squashfs-tools git python python-dev
tce-load -i make gcc compiletc openssl-dev squashfs-tools git python python-dev
mkdir -p /tmp/nodejs/usr/local
cd /tmp
wget
http://nodejs.org/dist/v8.11.3/node-v8.11.3.tar.gztar -xvf node-v8.11.3.tar.gz
cd node-v8.11.3
./configure --without-snapshot --prefix=/tmp/nodejs/usr/local
mksquashfs /tmp/nodejs/usr/local /tmp/nodejs_8_11_3.tcz
cp /tmp/nodejs_8_11_3.tcz /mnt/mmcblk0p2/tce/optional/
tce-load -i nodejs_8_11_3.tcz
