Command-line interface

njs scripts development and debugging can be performed from the command-line. The command-line utility is available after the installation of the Linux package or after building from the sources . Compared to njs running inside nginx, nginx objects ( HTTP and Stream ) are not available in the utility.

                    $ echo "2**3" | njs -
                    8
                    $ njs
                    >> var o = {a:[]}
                    undefined
                    >> JSON.stringify(o, undefined,1)
                    {
                    "a": [
                    ]
                    }
                    >>
