16 njs scripts development and debugging can be performed
17 from the command-line.
18 The command-line utility is available after the installation of
19 the Linux <link doc="install.xml" id="install_package">package</link>
20 or after building from the
21 <link doc="install.xml" id="install_sources">sources</link>.
22 Compared to njs running inside nginx,
23 nginx objects
24 (<link doc="njs_api.xml" id="http">HTTP</link> and
25 <link doc="njs_api.xml" id="stream">Stream</link>)
26 are not available in the utility.
