Install the Flux VS Code extension

The Flux VS Code extension is available in the Visual Studio Marketplace. For information about installing extensions from the Visual Studio marketplace, see the Extension Marketplace documentation.

Once installed, open the Explorer area of your VS Code user interface. A new InfluxDB pane is available below your file explorer.

Connect to InfluxDB

To create an InfluxDB connection in VS Code:

1. Hover over the InfluxDB pane and then click the icon that appears.

   

2. Provide the required connection credentials:

   • Type: type of InfluxDB data source. Select InfluxDB v2.
   • Name: unique identifier for your InfluxDB connection.
   • Hostname and Port: InfluxDB host and port (see InfluxDB OSS URLs or InfluxDB Cloud regions).
   • Token: InfluxDB API token.
   • Organization: InfluxDB organization name.

3. Click Test to test the connection.

4. Once tested successfully, click Save.

Manage InfluxDB connections

In the InfluxDB pane:

• To edit a connection, right click on the connection to edit and select Edit Connection.
• To remove a connection, right click on the connection to remove and select Remove Connection.
• To switch to a connection, right click on the connection to switch to and select Switch To This Connection.

Query InfluxDB from VS Code

1. Write your Flux query in a new VS Code file.
2. Save your Flux script with the .flux extension or set the VS Code Language Mode to Flux.
3. Press F5 to execute the query.
4. VS Code displays a list of InfluxDB connection configurations. Select which InfluxDB connection to use to execute the query.
5. Query results appear in a new tab. If query results do not appear, see Debug Flux queries.

Explore your schema

After you’ve configured an InfluxDB connection, VS Code provides an overview of buckets, measurements, and tags in your InfluxDB organization. Use the InfluxDB pane in VS code to explore your schema.

Debug Flux queries

To view errors returned from Flux script executions, click the Errors and Warnings icons in the bottom left of your VS Code window, and then select the Output tab in the debugging pane.

Upgrade the Flux extension

VS Code auto-updates extensions by default, but you are able to disable auto-update. If you disable auto-update, manually update your VS Code Flux extension. After updating the extension, reload your VS Code window (Ctrl+Shift+P, and then Reload Window) to initialize the updated extensions.
