The Omega supports NodeJS 4.3.1!
Connect to the Omega’s terminal using either SSH or Serial.
Run the following commands on the terminal:
opkg update opkg install nodejs
This will take about 8MB of space on the Omega.
Due to the 16MB size of the Omega’s flash storage, this installation will take up a sizeable chunk of the Omega’s memory. We recommend running the Omega’s OS from USB storage to have additional space for other programs and files.
The Omega also supports npm:
opkg update opkg install npm
The installation will take about 9MB of space.
Since npm requires node to be installed, it cannot fit on the flash storage on the Omega. You must run the Omega’s OS from USB storage in order to have enough space for this installation.
