What is dockViewR?

Draggable dock panels for Shiny, learning that layout state belongs on the client

dockViewR wraps the dockview JavaScript library so Shiny apps can offer draggable, splittable, tabbed panel layouts — the IDE arrangement, driven from R. Three releases since May 2025 have taken it from a working widget to one with a proper server-side control surface: panels can be added, removed, selected and moved from the server, and the dock exposes a reactive proxy.

What is v0 by Vercel?

v0 is turning a prompt-to-app toy into an addressable build service with a real workspace around it.

v0 ships a substantial digest roughly every two weeks, and the entries are long — 3,000 to 5,000 characters of genuine feature and fix detail, not version stamps. Three threads run through the last ten releases: making the agent programmatically addressable (Platform API v2, an expanding MCP server), deepening design and data sources (direct Figma inspection, Shopify, Snowflake), and hardening the parts users actually trip over (preview sandboxes, ZIP exports, Git-backed chats, scope and SSO bugs).

Draggable dock panels for Shiny, learning that layout state belongs on the client

◆ Current state

dockViewR wraps the dockview JavaScript library so Shiny apps can offer draggable, splittable, tabbed panel layouts — the IDE arrangement, driven from R. Three releases since May 2025 have taken it from a working widget to one with a proper server-side control surface: panels can be added, removed, selected and moved from the server, and the dock exposes a reactive proxy.

◆ Where it's heading

The design has been converging on the standard htmlwidgets pattern, and 0.3.0 is where it commits. Earlier releases routed panel-id checks through Shiny inputs, which meant the state was stale until the next reactive flush and forced awkward workarounds when manipulating the dock inside observeEvent(). Moving those checks to the browser and adding dock_view_proxy() drops that class of bug entirely, at the cost of a breaking API change and a dev-mode option for surfacing the warnings.

◆ Prediction

Having taken one breaking change to reach the proxy idiom, the natural follow-on is filling out the proxy surface so every panel operation is reachable through it.

v0 is turning a prompt-to-app toy into an addressable build service with a real workspace around it.

◆ Current state

v0 ships a substantial digest roughly every two weeks, and the entries are long — 3,000 to 5,000 characters of genuine feature and fix detail, not version stamps. Three threads run through the last ten releases: making the agent programmatically addressable (Platform API v2, an expanding MCP server), deepening design and data sources (direct Figma inspection, Shopify, Snowflake), and hardening the parts users actually trip over (preview sandboxes, ZIP exports, Git-backed chats, scope and SSO bugs).

◆ Where it's heading

The center of gravity is moving from the chat box to everything around it. Team governance arrived through deployment policies, restricted memories and skills on any paid plan, and request-access flows; the agent gained the ability to act on the workspace itself, listing, inspecting, creating and continuing other chats on request. Meanwhile the model layer is treated as swappable — Opus 4.7 Fast, then Opus 5 and Opus 5 Fast slot into a picker without ceremony — which says the durable moat is being built in the surrounding surface, not in whichever model is current.

◆ Prediction

Expect the Platform API to leave beta and the MCP tool set to keep widening toward full chat lifecycle control, with the workspace features that landed in August getting team-scoped equivalents.
