NAME

       nodejs - Server-side JavaScript runtime

SYNOPSIS

       nodejs [options] [v8 options] [script.js | -e "script" | - ] [--] [arguments]
       node debug [script.js | -e "script" | <host>:<port>] ...
       node [--v8-options]

       Execute without arguments to start the REPL.

DESCRIPTION

       Node.js is a set of libraries for JavaScript which allows it to be used outside of the browser. It is primarily focused on creating simple,
       easy to build network clients and servers.

OPTIONS

       -v, --version
              Print node's version.

       -h, --help
              Print node command line options.  The output of this option is less detailed than this document.

       -e, --eval "script"
              Evaluate the following argument as JavaScript.

       -p, --print "script"
              Identical to -e but prints the result.

       -c, --check
              Syntax check the script without executing.

       -i, --interactive
              Open the REPL even if stdin does not appear to be a terminal.

       -r, --require module
              Preload the specified module at startup. Follows `require()`'s module resolution rules. module may be either a path to a file, or  a
              node module name.

       --inspect[=[host:]port]
              Activate inspector on host:port. Default is 127.0.0.1:9229.

              V8  Inspector  integration  allows  attaching Chrome DevTools and IDEs to Node.js instances for debugging and profiling. It uses the
              Chrome Debugging Protocol.

       --inspect-brk[=[host:]port]
              Activate inspector on host:port and break at start of user script.

       --inspect-port=[host:]port
              Set the host:port to be used when the inspector is activated.

       --no-deprecation
              Silence deprecation warnings.

       --trace-deprecation
              Print stack traces for deprecations.

       --throw-deprecation
              Throw errors for deprecations.

       --pending-deprecation
              Emit pending deprecation warnings.

       --no-warnings
              Silence all process warnings (including deprecations).

       --napi-modules
              Enable loading native modules compiled with the ABI-stable Node.js API (N-API) (experimental).

       --abort-on-uncaught-exception
              Aborting instead of exiting causes a core file to be generated for analysis.

       --trace-warnings
              Print stack traces for process warnings (including deprecations).

       --redirect-warnings=file
              Write process warnings to the given file instead of printing to stderr.

       --trace-sync-io
              Print a stack trace whenever synchronous I/O is detected after the first turn of the event loop.

       --force-async-hooks-checks
              Enables runtime checks for `async_hooks`. These can also be enabled dynamically by enabling one of the `async_hooks` hooks.

       --trace-events-enabled
              Enables the collection of trace event tracing information.

       --trace-event-categories categories
              A comma separated list of categories that should be traced when trace event tracing is enabled using --trace-events-enabled.

       --zero-fill-buffers
              Automatically zero-fills all newly allocated Buffer and SlowBuffer instances.

       --preserve-symlinks
              Instructs the module loader to preserve symbolic links when resolving and caching modules.

       --track-heap-objects
              Track heap object allocations for heap snapshots.

       --prof-process
              Process V8 profiler output generated using the V8 option --prof

       --v8-options
              Print V8 command line options.

              Note: V8 options allow words to be separated by both dashes (-) or underscores (_).

              For example, --stack-trace-limit is equivalent to --stack_trace_limit

       --v8-pool-size=num
              Set v8's thread pool size which will be used to allocate background jobs.  If set to 0 then V8 will choose an  appropriate  size  of
              the  thread pool based on the number of online processors. If the value provided is larger than v8's max then the largest value will
              be chosen.

       --tls-cipher-list=list
              Specify an alternative default TLS cipher list. (Requires Node.js to be built with crypto support. (Default))

       --enable-fips
              Enable FIPS-compliant crypto at startup. (Requires Node.js to be built with ./configure --openssl-fips)

       --force-fips
              Force FIPS-compliant crypto on startup. (Cannot be disabled from script code.)  (Same requirements as --enable-fips)

       --openssl-config=file
              Load an OpenSSL configuration file on startup. Among other uses, this can be used to enable  FIPS-compliant  crypto  if  Node.js  is
              built with ./configure --openssl-fips.

       --use-openssl-ca,--use-bundled-ca
              Use  OpenSSL's  default  CA  store  or  use  bundled  Mozilla  CA store as supplied by current Node.js version. The default store is
              selectable at build-time.

              Using OpenSSL store allows for external modifications of the store. For most Linux and BSD distributions, this store  is  maintained
              by  the  distribution  maintainers and system administrators. OpenSSL CA store location is dependent on configuration of the OpenSSL
              library but this can be altered at runtime using environment variables.

              The bundled CA store, as supplied by Node.js, is a snapshot of Mozilla CA store that is fixed at release time. It  is  identical  on
              all supported platforms.

              See SSL_CERT_DIR and SSL_CERT_FILE.

       --icu-data-dir=file
              Specify ICU data load path. (overrides NODE_ICU_DATA)

       -      Alias for stdin, analogous to the use of - in other command line utilities, meaning that the script will be read from stdin, and the
              rest of the options are passed to that script.

       --     Indicate the end of node options. Pass the rest of the arguments to the script.

              If no script filename or eval/print script is supplied prior to this, then the next argument will be used as a script filename.

ENVIRONMENT VARIABLES

       NODE_DEBUG=module[,...]
              ','-separated list of core modules that should print debug information.

       NODE_DISABLE_COLORS=1
              When set to 1, colors will not be used in the REPL.

       NODE_EXTRA_CA_CERTS=file
              When set, the well known "root" CAs (like VeriSign) will be extended with the extra certificates in file. The file should consist of
              one  or  more trusted certificates in PEM format. A message will be emitted (once) with process.emitWarning() if the file is missing
              or misformatted, but any errors are otherwise ignored.

       NODE_ICU_DATA=file
              Data path for ICU (Intl object) data. Will extend linked-in data when compiled with small-icu support.

       NODE_NO_WARNINGS=1
              When set to 1, process warnings are silenced.

       NODE_NO_HTTP2=1
              When set to 1, the http2 module is suppressed.

       NODE_OPTIONS=options...
              A space-separated list of command line options. options... are interpreted as if they had been specified on the command line  before
              the  actual command line (so they can be overridden).  Node will exit with an error if an option that is not allowed in the environ-
              ment is used, such as -p or a script file.

       NODE_PATH=path[:...]
              ':'-separated list of directories prefixed to the module search path.

       NODE_PENDING_DEPRECATION=1
              When set to 1, emit pending deprecation warnings.

       NODE_REPL_HISTORY=file
              Path to the file used to store the persistent REPL history. The default path is ~/.node_repl_history, which is  overridden  by  this
              variable. Setting the value to an empty string ("" or " ") disables persistent REPL history.

       OPENSSL_CONF=file
              Load  an  OpenSSL  configuration  file  on startup. Among other uses, this can be used to enable FIPS-compliant crypto if Node.js is
              built with ./configure --openssl-fips.

              If the --openssl-config command line option is used, the environment variable is ignored.

       SSL_CERT_DIR=dir
              If --use-openssl-ca is enabled, this overrides and sets OpenSSL's directory containing trusted certificates.

       SSL_CERT_FILE=file
              If --use-openssl-ca is enabled, this overrides and sets OpenSSL's file containing trusted certificates.

       NODE_REDIRECT_WARNINGS=file
              Write process warnings to the given file instead of printing to stderr.  (equivalent to using the --redirect-warnings=file  command-
              line argument).
