Types and option builders
Catch errors early with strong typing
The Foundation SDK is strongly typed: your programming language checks configuration values as you write code, so many mistakes fail before the JSON ever reaches Grafana.
Instead of discovering a broken dashboard after sync, you can catch problems while you are still editing, such as:
- Invalid unit values
- Wrong data types for fields
Use option builders for complex settings
An option builder is a typed helper for one nested part of a panel or dashboard (for example reduce or display settings). When configuration gets nested, option builders keep that subsection readable and still typed.
Set a stable dashboard UID on the DashboardBuilder as well. A UID is a unique ID for the dashboard. When Git Sync later updates Grafana, the same UID means the existing dashboard is updated instead of a duplicate being created.
What you’ll practice next
In the learning path, you will compose builders, set a UID, and export JSON. Keep that file. It’s the dashboard JSON you commit to the repository Git Sync watches.
