# Vampires!

![Interview with the Vampire](https://mischiefmanagedsite.files.wordpress.com/2014/05/3.gif)

### Setup

1. Start `mongod`

2. Open your mongo console with `mongo`. Note: This homework is done in the terminal, there is no Express.

3. Connect to a new database called `monsters` with `use monsters`

4. Using the js objects of vampires in `populateVampires.js`, add the vampires to a `vampires` collection. Hint: you can use the **Adding Losts of New Documents** syntax from the example at the bottom of this document.

## MONGO SELECTION COMMANDS


***For the following parts, write mongo queries in your CLI, and when you figure out the right answer, copy the correct mongo queries into a `selectVampires.md` file.***

### Bonus

Make an express app and include Mongoose. Make a Mongoose schema for Items, populate the database with two items, then make an index route that will res.send the json for those items.

Extra bonus: Make a show route.
	
  
#### Adding Lots of New Documents in plain Mongo

Pretend we have a collection called `people` and want to add lots of documents, we can simply provide this __array__ to the _insert_ method and it will create a document for each object in the array.

```
[
  {
    "name": "Emma",
    "age": 20
  },
  {
    "name": "Ray",
    "age": 45
  },
  {
    "name": "Celeste",
    "age": 33
  },
  {
    "name": "Stacy",
    "age": 53
  },
  {
    "name": "Katie",
    "age": 12
  },
  {
    "name": "Adrian",
    "age": 47
  }
]
```

> Note: Be sure to type the closing parenthesis of the _insert_ method!

`db.people.insert([array])`
