Explore Your Data with Playgrounds¶
On this page
MongoDB for VS Code is currently available as a Preview in the Visual Studio Marketplace. The product, its features, and the corresponding documentation may change during the Preview stage.
MongoDB Playgrounds provide intelligent autocomplete for:
- The Mongo Shell API,
- MongoDB operators,
- Database, collection, and field names.
You can save playgrounds in your workspace and use them to
document how your application interacts with MongoDB. MongoDB for VS Code interprets
files with the
.mongodb extension as playgrounds.
You can also use your application to perform CRUD operations on documents using the appropriate driver. Playgrounds are meant to help you prototype database operations as you develop your application.
MongoDB for VS Code splits your Playground window to display your Playground Result in the right-side pane. You can perform one of two actions on the result depending on the query you ran in the Playground.
- You may save any Playground Result to a file.
You may edit any JSON document that MongoDB for VS Code returns in the Playground Result from a findOne or find query.
MongoDB for VS Code returns these results in JSON format with JSON syntax highlighting. Each JSON document has an Edit Document link at its top.
Click Edit Document at the top of the document you want to edit.
MongoDB for VS Code opens this one JSON document in a new window as an editable document.
- Make any changes you need.

To run a playground, you must connect to a MongoDB deployment using MongoDB for VS Code. To learn how to connect to a deployment, see either:
Open a Playground¶
Create a New Playground¶
You can create a new playground from the Playgrounds panel, the MongoDB for VS Code Overview page, or the Microsoft Visual Studio Code Command Pallette.
Open a Saved Playground¶
If you have files in your Visual Studio Code workspace with the
extension, MongoDB for VS Code displays these files in the Playgrounds
Double click a
.mongodb file to open that playground.
Run a Playground¶
To run a playground, click the Play Button in VS Code's top navigation bar. Your playground runs against the deployment specified in your active connection.
Connect to a Deployment from a Playground¶
If MongoDB for VS Code is not connected to a MongoDB deployment, you can specify a connection string for the deployment you want to run your playground against.
If you have a playground file open in Visual Studio Code and do not have an active connection, MongoDB for VS Code displays Click here to add connection at the top of your playground.
- Click this link to open the connection string dialog.
- Enter the connection string for the deployment you want to run this playground against.
- Press Enter.
- Run your playground.
When you connect to a deployment through the playground connection dialog, that connection is added to your MongoDB for VS Code Connections list.
Run Selected Lines of a Playground¶
If you select a section of your playground, you may optionally run only the selected portion. You may run either a single line or multiple lines of your playground.
MongoDB for VS Code shows the Run Selected Lines from Playground link immediately above your selected section. Click this link to test and troubleshoot specific lines or sections of your playground.
Log to Console from a Playground¶
MongoDB for VS Code supports the following methods to log messages to the console. Logged messages appear in the Output panel in VSCode.
Logging to the console can be useful to track the output of certain commands in your playground, such as results after a particular query or aggregation.
Consideration for Authentication¶
If your deployment requires authentication, your database user privileges may affect the actions you can perform using MongoDB for VS Code.
