For many, this is sufficient for their needs. If this is you, this extension is not for you. + +However, some wish to use software development tools (e.g. git) to manage their dashboards and other observability resources. Dashboards can be exported as JSON, however this JSON is hard to understand and interpret. This extension allows you to: +- Open a Grafana dashboard JSON file +- Start a live preview of that dashboard inside VS Code, connected to live data from a Grafana instance of your choice +- Edit the dashboard in the preview, using the normal Grafana dashboard editor UI +- From the editor UI, save the updated dashboard back to the original JSON file + +Managing dashboards as code moves the single source of truth from Grafana itself to your version control system, which allows for dashboards to participate in gitops style workflows that are commonly used for much of the rest of software development. + +> **This library is experimental** +> +> The code in this repository should be considered experimental.

Then select `Extensions`. + +### Configure the Extension +1. Provide the default URL for your Grafana instance in the `URL` field.

Create a [Service account in Grafana](https://grafana.com/docs/grafana/latest/administration/service-accounts/#create-a-service-account-in-grafana) and add a token to it. +3. In the VS Code settings, click `Set your token, securely` then paste your token into the popup. Press ENTER. + +### Using the Extension +1. Open a folder on your computer that has some dashboard JSON (if you don't have any of your own, navigate to the `dashboards` folder of [this repo](https://github.com/grafana/grafana-vs-code-extension/tree/main/dashboards)). +2. Right-click on a dashboard JSON file in the file explorer and select `Edit in Grafana`. +3. Have fun! +4.

Run `yarn install` in this repo. +3. Open this repo VS Code, then press `F5` to start the extension locally. +4. Continue from step 4 above. + +### Develop +To make changes to this codebase, follow the instructions about how to run from this repository. Then, in your original VS Code window, make changes to the extension. Then, restart the extension with either CTRL+SHIFT+F5 (CMD+SHIFT+F5 on a Mac) or by clicking the green restart circle. + +To view debug logs, use CTRL+SHIFT+P (CMD+SHIFT+P on Mac) then select "Developer: Open Webview Developer Tools". + +## Extension Settings +- `grafana-vscode.URL`: Set the URL of the Grafana instance you want to open the dashboard in. Defaults to 'http://localhost:3000'. +- `grafana-vscode.service-account-token`: A Service Account token. This is stored in the operating system secret store. Defaults to an empty string. + +## Extension communication with Grafana +Details of how this extension communicates with Grafana is available
