> A quick guide to learn how to use async-await to connect with MongoDB using Mongoose.

The `connect()` method provided by the [Mongoose](https://attacomsian.com/blog/nodejs-getting-started-with-mongoose) supports both JavaScript [promises](https://attacomsian.com/blog/promises-javascript) and [async-await](https://attacomsian.com/blog/async-await-javascript) syntax.

The following example demonstrates how you can use promises to create a connection with MongoDB:

```javascript
const mongoose = require('mongoose')

const server = '127.0.0.1:27017' // REPLACE WITH YOUR OWN SERVER
const database = 'test'          // REPLACE WITH YOUR OWN DB NAME

mongoose
  .connect(`mongodb://${server}/${database}`)
  .then(() => {
    console.log('MongoDB connected!!')
  })
  .catch(err => {
    console.log('Failed to connect to MongoDB', err)
  })
```

To use async-await syntax, you need to write an asynchronous function, as shown below:

```javascript
const mongoose = require('mongoose')

const server = '127.0.0.1:27017' // REPLACE WITH YOUR OWN SERVER
const database = 'test'          // REPLACE WITH YOUR OWN DB NAME

const connectDB = async () => {
  try {
    await mongoose.connect(`mongodb://${server}/${database}`)

    console.log('MongoDB connected!!')
  } catch (err) {
    console.log('Failed to connect to MongoDB', err)
  }
}

connectDB()
```
