SvGrid Studio · dashboard

What this example shows

Data-app Studio · dashboard - a schema-driven dashboard above the grid.

`SvSchemaDashboard` renders a declarative `DashboardSpec` (KPI tiles + charts) over the same `EntitySchema` + rows as the grid. It's a data VIEW, not a page builder: KPIs reduce a measure to one number, charts reuse `SvSchemaChart`. Click a chart category to drill the grid; create / edit / delete updates both.

More Studio examples

• SvGrid Studio · live SQL - The Studio stack backed by a REAL Postgres running in the browser via PGlite (WASM), no server. createSqlDataSource turns the grid's sort / filter / page requests into parameterized SQL run through PGlite; the executed query is shown live under the toolbar. Full CRUD with optimistic updates against actual Postgres.
• Northwind on PGlite - The classic Northwind sample DB (categories, customers, products, orders, order_details) seeded into a real in-browser Postgres (PGlite, WASM). Switch between a five-table JOIN exposed as a read-only VIEW and the editable base tables - each via createSqlDataSource. Sort / filter / page / edit all run as parameterized SQL; new rows get an auto id from a Postgres IDENTITY sequence.
• SvGrid Studio · Supabase - The Studio stack over hosted Postgres on Supabase, straight from the browser via supabase-js (PostgREST) and your project's public anon key. createSupabaseDataSource maps the grid's sort / filter / page / CRUD onto the query builder, introspectSupabaseTable adapts to any table AND detects foreign keys (a FK column auto-becomes a searchable lookup in the form), and createSupabaseRealtime makes it LIVE - change a row in the Supabase dashboard and it flashes in the grid (toggle the Live pill). Paste your URL + anon key, run the one-time setup SQL, done. RLS keeps the anon key safe.
• SvGrid Studio · relations - Foreign-key lookup fields end to end. Contacts belong to a Company: the contact form renders a searchable Company picker (SvLookupInput + createRelationLookup) that queries the Companies source and stores the id, while the grid shows the resolved company NAME. The lookup runs over the same ServerDataSource contract, so related options can come from Supabase / REST / SQL / in-memory (here both entities are in-memory).
• SvGrid Studio · secured - A secured screen: SvAuthGate requires a signed-in user (Supabase Auth via createSupabaseAuth) before showing the Studio grid, with a login / sign-up form and a signed-in bar. Uses a mock auth client so any email + password works here; swap for your supabase-js client and Row-Level Security scopes each user to their own rows (auth = who, RLS = what).
