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.
