How do you pipe scripts into NodeJs from command line?

Question

From command line, I'd like to take a script from my paste board (FYI: pbpaste is an OSX feature) and pipe it into the Node's repl command line tool. For example:

pbpaste | node -e

This does not evaluate the contents in my clipboard. How do I get the runtime to do this?

It should just work without the -e, I think.

The -e option is for running JS passed as an argument. To run JS from stdin, you can simply pipe to node directly.

pbpaste | node

I can't get this to work for piping a downloaded script to node. (i.e. "curl -L https://<myscipt> | node")

This seems to do the trick:

node -e "$(pbpaste)"

node -e "process.stdout.write('hi');"
