This is a tiny library for adding custom trace data to error objects for easier debugging. Read the [blog post]().

[![npm version](https://badge.fury.io/js/succinct-async.svg)](https://badge.fury.io/js/succinct-async)

Example:

```js

class Thing {

  something() {

    throw new Error("Oops")

  }

  async somethingElse(cb) {

    this.something(await fetch('/'))

  }

}

instrumentObject(Thing.prototype)

const doStuff = instrument('doStuff', async () => {

  const thing = new Thing()

  await thing.somethingElse()

})

doStuff()

/*

Uncaught (in promise) Error: Oops

    at Thing.something (:3:11)

    at Thing.wrapper (:11:18)

    at Thing.somethingElse (:6:10)

    at async :15:3

 Intercepted in:

	 Thing.something

	 Thing.somethingElse

	 doStuff

*/

```
