# Providing a MongoDB Connection

{% hint style="info" %}
To **setup** a MongoDB database, you will need to **create a MongoDB Atlas Database** in the Cloud. Unless you already have a local/cloud database, please follow these [steps](https://www.mongodb.com/basics/mongodb-atlas-tutorial).
{% endhint %}

Once you get your connection string, **paste it** into `mongoDB.uri` option in the NoCliHandler instance. If you are using your local MongoDB database, I recommend you to use this type of connection string:

```bash
# With username and password
mongodb://<username>:<password>@localhost/<database_name>
# Without username and password
mongodb://localhost/<database_name>
```

{% hint style="warning" %}
It is **recommended** for you to store your connection string in an **environment file** when you are going to share your code. This is because hackers can **hijack your database** and mess around with it.
