## Feature Request
It would be nice to write MongoDB playground in Typescript, then we will have design time validation and good suggestions in IDE.
## Detailed Description
It would be awesome to have types for MongoDB interfaces and the ability to import your own types.
```ts
import {Sale} from './types';
use('mongodbVSCodePlaygroundDB');
const sales: Sale[] = [
{ 'item': 'abc', 'price': 10, 'quantity': 2, 'date': new Date('2014-03-01T08:00:00Z') },
{ 'item': 'jkl', 'price': 20, 'quantity': 1, 'date': new Date('2014-03-01T09:00:00Z') },
{ 'item': 'xyz', 'price': 5, 'quantity': 10, 'date': new Date('2014-03-15T09:00:00Z') },
{ 'item': 'xyz', 'price': 5, 'quantity': 20, 'date': new Date('2014-04-04T11:21:39.736Z') },
{ 'item': 'abc', 'price': 10, 'quantity': 10, 'date': new Date('2014-04-04T21:23:13.331Z') },
{ 'item': 'def', 'price': 7.5, 'quantity': 5, 'date': new Date('2015-06-04T05:08:13Z') },
{ 'item': 'def', 'price': 7.5, 'quantity': 10, 'date': new Date('2015-09-10T08:43:00Z') },
{ 'item': 'abc', 'price': 10, 'quantity': 5, 'date': new Date('2016-02-06T20:20:13Z') },
]
db.getCollection('sales').insertMany(sales);
```
##Possible Implementation
We can define `global.d.ts` for MongoDB db global and transpile the file into js before running.
