Simple MongoDB Keyv Adapter

Why?

The MongoDB adapter for keyv is fine but I needed a way to pass an existing connection to the adapter.

In the current implementation, the constructor connects to the MongoDB by itself, I couldn't make it work by extending the current class.

So I created my own MongoDB adapter, based on the existing one, removing the feature about MongoDB GridFS I didn't need.

// Compound Components

import React from 'react'
import {Switch} from '../switch'

class Toggle extends React.Component {
  // you can create function components as static properties!
  // for example:
  // static Candy = (props) => <div>CANDY! {props.children}</div>
  // Then that could be used like: <Toggle.Candy />

/*
Context: we have an API that throws an error (not wrapped in a Promise).
We want to catch that error at the upper level, without making fail the main function
that should end normally.
*/
function apiRequest() {
  throw new Error('Big Bug')
}
