.SH 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.

|
on the number of online processors. If the value provided is larger than v8's
|
|
|
|
|
max then the largest value will be chosen.

|
|
|
|
|
|
|
|
|
|
.TP
|
|
|
|
|
.BR \-\-openssl\-config =\fIfile\fR
|
|
|
|
|
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
|
|
|
|
|
\fB./configure \-\-openssl\-fips\fR.

|
|

.TP
|

.BR \-\-use\-openssl\-ca,\-\-use\-bundled\-ca
|
|
|
|
|
Use OpenSSL's default CA store or use bundled Mozilla CA store as supplied by
|
|
|
|
|
current NodeJS 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
|
|
|
|
|
environmental variables.
|
|
|
|
|
|
|
|
|
|
The bundled CA store, as supplied by NodeJS, is a snapshot of Mozilla CA store
|
|
|
|
|
that is fixed at release time. It is identical on all supported platforms.

.BR \-\-\fR
|
|

|
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.

\fBoptions...\fR are interpreted as if they had been specified on the command

value to an empty string ("" or " ") disables persistent REPL history.

.BR OPENSSL_CONF = \fIfile\fR
