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.

.connect("mongodb://127.0.0.1/playground")
|

|
|
|
.then(() => console.log("Connected to MongoDB"))

.catch((err) => console.error(err));

```
