# callsites

> Get callsites from the [V8 stack trace API](https://github.com/v8/v8/wiki/Stack-Trace-API)

## Install

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

## Usage

```js
const 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:

* `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.
* `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 top-level 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?
