low.js is a port of Node.JS with far lower system requirements.
low.js starts up instantly, while Node.js does not (0.6 to 1.5 seconds wait time on Raspberry Pi 2).
low.js only uses a fraction of the disk space and memory which Node.js requires, leaving more resources for other processes.
For more information on low.js, please visit http://www.lowjs.org/ .
First steps / documentation
To try out low.js, download the webserver example which you can run with both low.js and Node.js.
The documentation is located at lowjs documentation.
Compile from source
In case the binary distributions available at http://www.lowjs.org/ do not work for your needs, you can compile from source.
Before compiling, make sure you have the following software installed:
make g++ automake autoconf libtool python py-pip nodejs npm (if not already installed together with nodejs)
Note: Node.js is only used to transpile the low.js libs from ES6 to ES5. It is only need for the build process. The binary distributions of low.js available on http://www.lowjs.org/ do not include Node.js, of course - this would defeat the purpose.
With this software installed, please install pyyaml with pip:
pip install pyyaml
The compilation itself can be done with these commands:
git clone --recurse-submodules https://github.com/neonious/lowjs cd lowjs make
low.js is now built in bin and can be called via bin/low.
The lib directory is also required for low to work (it accesses it via path_to_bin/../lib) and must be copied when creating a distribution. When creating a distribution, it might also make sense to strip the binary with the strip command, to save some KB.
Please see the lowjs test documentation.
