Add `caller-id` as a dependency to your project’s `package.json`\r\n2. Run `npm install`\r\n\r\n## Usage Examples\r\n\r\n### `getData`\r\n\r\n`getData()` can be used to get raw data about a function's caller\r\n\r\n    var callerId = require('caller-id');\r\n\r\n    // 1. Function calling another function\r\n    function foo() {\r\n        bar();\r\n    }\r\n    function bar() {\r\n        var caller = callerId.getData();\r\n        /*\r\n        caller = {\r\n            typeName: 'Object',\r\n            functionName: 'foo',\r\n            filePath: '/path/of/this/file.js',\r\n            lineNumber: 5,\r\n            topLevelFlag: true,\r\n            nativeFlag: false,\r\n            evalFlag: false\r\n        }\r\n        */\r\n    }\r\n\r\n    // 2. Method in a class calling a function\r\n    function Lorem() {}\r\n    Lorem.prototype.ipsum = function() {\r\n        baz();\r\n    }\r\n    function baz() {\r\n        var caller = callerId.getData();\r\n        /*\r\n        caller = {\r\n            typeName: 'Lorem',\r\n            functionName: 'Lorem.ipsum',\r\n            methodName: 'ipsum',\r\n            filePath: '/path/of/this/file.js',\r\n            lineNumber: 25,\r\n            topLevelFlag: false,\r\n            nativeFlag: false,\r\n            evalFlag: false\r\n        }\r\n        */\r\n    }\r\n\r\n    // 3. Function in an eval calling another function\r\n    function func() {\r\n        var caller = callerId.getData();\r\n        /*\r\n        caller = {\r\n            typeName: 'Object',\r\n            functionName: 'evil',\r\n            lineNumber: 2,\r\n            topLevelFlag: true,\r\n            nativeFlag: false,\r\n            evalFlag: true,\r\n            evalOrigin: 'eval at <anonymous> (/path/of/this/file.js:58:7)'\r\n        }\r\n        */\r\n    }\r\n    eval('(function evil() {' + '\\\\n' +\r\n        'func();' + '\\\\n' +\r\n        '})();');\r\n\r\n### `getString`\r\n\r\n`getString()` returns a brief string representing a function's caller\r\n\r\n    var callerId = require('caller-id');\r\n\r\n    function myFunction() {\r\n        var callerString = callerId.getString();\r\n    }\r\n\r\nUsing the same examples as above, `getString()` returns the following:\r\n\r\n1.  foo\r\n2.  Lorem.ipsum\r\n3.  (eval)evil\r\n\r\n### `getDetailedString`\r\n\r\n`getDetailedString()` returns a more detailed string representing a function's caller\r\n\r\n    var callerId = require('caller-id');\r\n\r\n    function myFunction() {\r\n        var detailedCallerString = callerId.getDetailedString();\r\n    }\r\n\r\nUsing the same examples as above, `getDetailedString()` returns the following:\r\n\r\n1.  foo at /path/of/this/file.js:5\r\n2.  Lorem.ipsum at /path/of/this/file.js:25\r\n3.  eval at <anonymous> (/path/of/this/file.js:58:7)",
