# callsites [](https://travis-ci.org/sindresorhus/callsites) | |
> Get callsites from the [V8 stack trace API](https://v8.dev/docs/stack-trace-api) | |
## Install | |
``` | |
$ npm install 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: | |
- `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 string 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? | |
