You can get it to through npm with:

# Windows
npm install -g

# Linux/Mac
sudo npm install -g

Node.js 4.0 is our runtime for project development. The project targets 0.10.x (to support old ARM without VFP4) and 0.12.x branches too.

To list the supported commands and start with:

# print available commands
ljve help

# launch environment without development tools (production) 
ljve run

# launch environment with development tools (web terminal, console and ide)
ljve develop

# launch environment with both development tools (see above) and debugger enabled
ljve debug

To get started, create a new application boilerplate with:

# create a folder that will contain app files on Linux/Mac
mkdir -p ~/ljve/hello
cd ~/ljve/hello
# initialiaze boilerplate using default template (in current folder)
ljve create
# create a folder that will contain app files on Windows
mkdir -p %HOMEPATH%\Desktop\ljve\hello
cd %HOMEPATH%\Desktop\ljve\hello
# initialiaze boilerplate using default template (in current folder)
ljve create

Start the environment and empty application with:

# launch environment and application with all development tools enabled
ljve debug

You can now have fun visiting ports 9090 (web console), 9091 (web debugger), 9092 (web ide) and 9093 (web terminal).
