# callsites [![Build Status](https://travis-ci.org/sindresorhus/callsites.svg?branch=master)](https://travis-ci.org/sindresorhus/callsites)

> Get callsites from the [V8 stack trace API](https://code.google.com/p/v8/wiki/JavaScriptStackTraceApi)


## Install

```sh
$ npm install --save callsites
```


## Usage

```js
var callsites = require('callsites');

function unicorn() {
	console.log(callsites()[0].getFileName());
	//=> /Users/sindresorhus/dev/callsites/test.js
}

unicorn();
```

## API

Returns an array of callsite objects with the following methods:

- `getThis`: returns the value of this
- `getTypeName`: returns the type of this as a string. This is the name of the function stored in the constructor field of this, if available, otherwise the object's [[Class]] internal property.
- `getFunction`: returns the current function
- `getFunctionName`: returns the name of the current function, typically its name property. If a name property is not available an attempt will be made to try to infer a name from the function's context.
- `getMethodName`: returns the name of the property of this or one of its prototypes that holds the current function
- `getFileName`: if this function was defined in a script returns the name of the script
- `getLineNumber`: if this function was defined in a script returns the current line number
- `getColumnNumber`: if this function was defined in a script returns the current column number
- `getEvalOrigin`: if this function was created using a call to eval returns a CallSite object representing the location where eval was called
- `isToplevel`: is this a toplevel invocation, that is, is this the global object?
- `isEval`: does this call take place in code defined by a call to eval?
- `isNative`: is this call in native V8 code?
- `isConstructor`: is this a constructor call?
