npm install node-module-info --save

Example

var getInfo = require("node-module-info");
getInfo("./module1", "/path/to/caller/");
getInfo("dependence1/file1", "/path/to/caller/");
getInfo("/absolute/file/of/module", "/path/to/caller/");
getInfo("/module/without/caller");

Usage

Lib supports:

getCallerInfo: () => Info; //return same info about caller
getFullPath: () => string; //get full path (resolved only for dependence)
getResolvedPath: () => string;  //resolve module path, throw error for non-existing
getRootPath: () => string; //root path of app (get first path, before first node_modules)
getPackagePath: () => string; //package path for current module
getRelativePath: () => string; //relative path from package path
getRelativeName: () => string; //relative path without extension
getDefineName: ()=>string;//name for use with builders, `npm!package@version#path`
isAbsoulte: () => boolean; //is module path absolute
isDependence: () => boolean; //is dependence of caller (if caller setted) or false
isRelative: () => boolean; //is starts with "." if caller setted, or if not absolute
isSystem: () => boolean; //if caller setted check for internal modules
getPackageInfo: () => { //info from package.json from package path
    name: string;
    version: string;
    ///...full info
};
