There are a variety of command line options for Node.js
Lets take a look at the list of Node.js command line options:
| Option | Description |
|---|---|
| v, –version | This is used to print node's version. |
| -h, –help | This is used to print node command line options. |
| -e, –eval “script” | This evaluates the following argument as JavaScript. The modules which are predefined in the REPL can also be used in script. |
| -p, –print “script” | This is identical to -e but prints the result. |
| -c, –check | Syntax check the script without executing. |
| -i, –interactive | This opens the REPL even if stdin does not appear to be a terminal. |
| -r, –require module | This is used to preload the specified module at startup. It 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 | This is used to print stack traces for deprecations. |
| –throw-deprecation | This throws errors for deprecations. |
| –no-warnings | This will silence all process warnings (this includes deprecations). |
| –trace-warnings | This prints stack traces for process warnings (this includes deprecations). |
| –trace-sync-io | This prints a stack trace whenever synchronous i/o is detected after the first turn of the event loop. |
| –zero-fill-buffers | Automatically zero-fills all newly allocated buffer and slow buffer instances. |
| –track-heap-objects | This tracks heap object allocations for heap snapshots. |
| –prof-process | This processes V8 profiler output generated using the v8 option –prof. |
| –V8-options | This prints V8 command line options. |
| –tls-cipher-list=list | This specifies an alternative default tls cipher list. (this requires node.js to be built with crypto support. (default)) |
| –enable-fips | It enables fips-compliant crypto at startup. (this requires node.js to be built with ./configure –openssl-fips) |
| –force-fips | This forces fips-compliant crypto on startup. (this cannot be disabled from script code.) (it has the same requirements as –enable-fips) |
| –icu-data-dir=file | This specifies ICU data load path. (Overrides node_icu_data) |
