NAME
    Nodejs::Util - Utilities related to Node.js

VERSION
    This document describes version 0.012 of Nodejs::Util (from Perl
    distribution Nodejs-Util), released on 2018-03-21.

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) => str|array

    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").

    Will return undef if no module is found, or string containing the found
    path.

    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
        string containing the first found path.
