NAME
Nodejs::Util - Utilities related to Node.js
VERSION
This document describes version 0.009 of Nodejs::Util (from Perl
distribution Nodejs-Util), released on 2018-01-07.
FUNCTIONS
nodejs_available
Usage:
nodejs_available(%args) -> [status, msg, result, meta]
Check the availability of Node.js.
This is a more advanced alternative to "nodejs_path()". Will check for
"node" or "nodejs" in the PATH, like "nodejs_path()". But you can also
specify minimum version (and other options in the future). And it will
return more details.
Will return status 200 if everything is okay. Actual result will return
the path to executable, and result metadata will contain extra result
like detected version in "func.version".
Will return satus 412 if something is wrong. The return message will
tell the reason.
This function is not exported by default, but exportable.
Arguments ('*' denotes required arguments):
* all => *bool*
Find all node.js instead of the first found.
If this option is set to true, will return an array of paths intead
of path.
* min_version => *str*
* path => *str*
Search this instead of PATH environment variable.
Returns an enveloped result (an array).
First element (status) is an integer containing HTTP status code (200
means OK, 4xx caller error, 5xx function error). Second element (msg) is
a string containing error message, or 'OK' if status is 200. Third
element (result) is optional, the actual result. Fourth element (meta)
is called result metadata and is optional, a hash that contains extra
information.
Return value: (any)
nodejs_path
Usage:
nodejs_path(%args) -> any
Check the availability of Node.js executable in PATH.
Return the path to executable or undef if none is available. Node.js is
usually installed as 'node' or 'nodejs'.
This function is not exported by default, but exportable.
Arguments ('*' denotes required arguments):
* all => *bool*
Find all node.js instead of the first found.
If this option is set to true, will return an array of paths intead
of path.
Return value: (any)
system_nodejs
Usage:
system_nodejs([ \%opts ], @argv)
Will call IPC::System::Options's system(), but with node.js binary as
the first argument. Known options:
* harmony_scoping => bool
If set to 1, will attempt to enable block scoping. This means at
least node.js v0.5.10 (where "--harmony_scoping" is first
recognized). But "--harmony_scoping" is no longer needed after
v2.0.0 and no longer recognized in later versions.
* path => str
Will be passed to "nodejs_available()".
Other options will be passed to "IPC::System::Options"'s "system()".
nodejs_module_path
Usage:
nodejs_module_path([ \%opts, ] $module)
Search module in filesystem according to Node.js rule described in
<https://nodejs.org/api/modules.html>. $module can be either a
relative/absolute path (e.g. "./bip39.js", "../bip39.js", or
"/home/foo/bip39.js"), a filename (e.g. "bip39.js"), or a filename with
the ".js" removed (e.g. "bip39").
Known options:
* parse_package_json => bool (default: 0)
Not yet implemented.
* cwd => str
Use this directory instead of using "Cwd::get_cwd()".
* all => bool
If set to true, will return an array of all found paths instead of
the first found path.
