Detecting shelljs/node

[hemanth]

Is there a way detect if shelljs or node is installed in the system, within the script. I know it's kina dumb but, say in bash script it's possible to get the the $SHELL

Asking this because, say one decides to write a setup script with shelljs, then node becomes a dependency to get shelljs first....so bit confused... env['NODE_PATH'] would be useful? But also, can we know if shelljs is installed or not and then install it within shelljs 0_o

not sure what you mean. if you don't have Node you won't be able to run the script at all. as for detecting ShellJS, do you mean locally or globally (as in the command shjs)? can you please clarify?
