Ops workspace
An on-call workspace on SvDockManager that runs a whole incident: a deploy rolls out and the service degrades, an alert rule tints its row and opens an incident, the on-call primary is paged and acknowledges, and rolling the deploy back recovers it. Panes hold a live service grid, p50 / p95 / p99 latency and error charts, an incident board (one SvGrid, Board or Table), deploys, on-call and an alert feed; an incident opens a drawer with its timeline, notes, severity and status. Panes drag, tab, float and save. (requires @svgrid/enterprise)
A live, editable Svelte 5 data grid example from the SvGrid gallery (App Templates). See the SvGrid documentation for the full API.
About this example
An on-call operations workspace in Svelte 5 built on SvDockManager that runs a whole incident. A deploy rolls out and the service degrades; an alert rule tints its row in the live service grid and opens an incident; the team's on-call primary is paged and acknowledges; rolling the deploy back recovers the service and moves the incident to Mitigated. Panes hold p50, p95 and p99 latency and error charts, a Kanban incident board that switches to a table, deploys, on-call and an alert feed. Each incident opens a drawer with its timeline, notes, severity and status, and the pane layout saves to localStorage.
An on-call workspace on SvDockManager. Panes: a live service grid, p50 / p95 / p99 latency and error charts for the selected service, an incident board (Board or Table over the same SvGrid), deploys, on-call and an alert feed. Every pane drags, tabs, floats and auto-hides, and the arrangement saves to localStorage.
The panes run one incident loop, the way a real on-call tool does: 1. A deploy goes out (progress, then live) and the service degrades. 2. An alert rule fires: the row tints, the feed logs it, an incident opens in Triage and the team's primary is paged. 3. The primary acknowledges; the incident's timeline records each step. 4. Rolling back the deploy recovers the service and moves the incident to Mitigated; resolve it from the incident drawer. A scripted bad deploy runs the loop a few seconds after load; Inject failure runs it again on the selected service.

Frequently asked questions
Which parts of this template need @svgrid/enterprise?
The alert rules engine, the Kanban board renderer and export. The docking layout, the live grid, the sparklines, the charts and the incident drawer are in the MIT @svgrid/grid package.
How does an alert open an incident?
The alert rules write fired events to alertStore. An effect in the template reads new events from its own two rules and opens an incident for the service, or escalates the open one if the new event is more severe, then pages the team's primary. Events fired before the workspace mounted are ignored.
What goes on an incident's timeline?
Every change: who opened it and why, each page and acknowledgement, severity, status and commander changes, the rollback, and any note typed in the drawer. Each entry carries its time and author, which is what a postmortem is written from.
Can users rearrange and keep the layout?
Yes. Panes drag between tab groups, float, maximize and auto-hide. The whole arrangement is one serializable DockManagerState; Save layout writes it to localStorage and the workspace reads it back on load. Reset restores the default.
Where would real metrics and deploys come from?
The tick function stands in for a metrics feed and ship() for your deploy pipeline. Replace them with a WebSocket or a poll that writes rows into the services and deploys arrays; the grid, the alert rules, the charts, the KPIs and the incident loop all read from those arrays.

- Mail client - An Outlook-shaped mail client in one file. The inbox is a SvGrid with sender avatars, conversation counts, quick filters, hover actions and bulk actions on ticked rows; the reading pane shows the whole conversation with quoted text folded; the SvRichText composer has recipient chips with contact suggestions, Cc, attachments, a signature and a five-second Undo send. New mail arrives while the page is open, Gmail-style keys work (press ?), an accepted invite lands on the Calendar module (the same grid as a scheduler), and Export writes a folder to Excel, CSV or PDF.
