# Connect to a database with Mongoose
|
|
|
|
Now that we have installed and configured MongoDB, we need to connect to it via Node.js. Mongoose is a simple API for interacting with a Mongo database via Node.
|
|
|
|
With Mongoose installed we can connect to a database. We don't have any Mongo databases yet beyond the defaults but the following Mongoose connection logic will create and connect to a new database called `playground`:

|
|
Providing the Mongo server is running (execture `mongod`), we will see the confirmation message in the console.
|
|
|
|
```js
|
|
mongoose
|
|
.connect('mongodb://127.0.0.1/playground')
|
|
.then(() => console.log('Connected to MongoDB'))
|
|
.catch((err) => console.error(err));
|
|
```
