NODE(1)

NAME
node - Server-side JavaScript runtime

SYNOPSIS
node [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
    Opens 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.

--no-deprecation
    Silence deprecation warnings.

--trace-deprecation
    Print stack traces for deprecations.

--throw-deprecation
    Throw errors for deprecations.

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

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

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

--prof-process
    Process v8 profiler output generated using the v8 option --prof

--v8-options
    Print v8 command line options.

--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)

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

ENVIRONMENT VARIABLES

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

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

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

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

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.
