Streamline Studio roadmap to 3-phase plugin infrastructure plan for 2026 by Claude · Pull Request #1160 · objectstack-ai/framework

Claude · 2026-04-16T01:46:21Z

The Studio roadmap contained overly ambitious goals across 8 phases and lacked clarity on what belongs in the core platform versus external plugins. This update establishes Studio as a plugin infrastructure platform rather than a monolithic IDE.

Architectural Clarification

Core Studio (this repo):

Plugin system, kernel, routing, testing infrastructure
One built-in example: Basic Object Inspector plugin

Official Designers (objectstack-ai/studio - proprietary):

Object Designer, View Designer, Form Designer, Flow Designer, Dashboard Designer, Agent Designer

Community Plugins:

Third-party developers can build custom designers independently

Roadmap Changes

Consolidated: 8 phases (29 weeks) → 3 phases (16 weeks)
Phase 1 (Q2): Plugin infrastructure (URL router, testing, hot reload, plugin API docs)
Phase 2 (Q3): AI integration (Copilot enhancement, Command Palette, Monaco Editor)
Phase 3 (Q4): Advanced IDE features (multi-tab, plugin DevTools, version control)

Key Additions

Plugin Ecosystem section: Documents three-tier model (built-in/official/community)
Architectural Guidelines: File structure, registration patterns, data access rules
Success Metrics: Realistic KPIs for test coverage, plugin API stability, external plugin count
"What We're NOT Building": Clear scope boundaries for core vs. external plugins

This establishes an open-core business model: infrastructure is open-source, advanced designers are proprietary.

Pull request overview

Updates Studio’s roadmap to a 3-phase “plugin infrastructure” plan and begins implementing Phase 1 foundations (routing + testing + sidebar plugin integration) to position Studio as an extensible plugin host rather than a monolithic IDE.

Changes:

Refactors Studio navigation to TanStack Router (new route files, router setup, Vite plugin integration).
Adds Vitest + Testing Library setup and initial component/plugin-system tests.
Updates metadata plugin tests to validate bridging ObjectQL as a data engine (setDataEngine) and removes dead Studio task types.

apps/studio/src/components/app-sidebar.tsx:382

The Overview nav item is marked active only when a package route param exists, but the actual overview page currently lives at / (no params). Also, the click target navigates to /${selectedPackageId}, which currently maps to the /$package layout that renders an empty <Outlet /> (no index route). Align the Overview nav's active logic and navigation target with the actual overview route (e.g., add a /$package index route and/or redirect / → /$package).

onSelectPackage is wired to setSelectedPackage, but this route also syncs selectedPackage from the URL param in an effect. If the user selects a different package from the sidebar dropdown while staying on the same /$package/... URL, the effect will immediately revert the selection back to the package in the URL. Consider making package selection drive navigation (update the package param) and deriving selectedPackage from the router params to keep state/URL consistent.

/$package is being used as a layout route (sidebar + header + <Outlet />), but there is no index/child route that renders the package overview. Navigating to /${packageId} will therefore render an empty main content area. Consider adding an index child route under /$package for the overview (or render the overview directly here instead of an empty <Outlet />).

This test references React.ReactElement, but React is not imported anywhere in the file. With jsx: react-jsx, the React namespace is not global, so this will fail typechecking. Either import type React from 'react' (or import type { ReactElement } from 'react') or change the annotation to JSX.Element / ReactElement without the React. namespace.

This route is declared as a child of /$package (see routeTree.gen.ts), but it also renders its own AppSidebar + <main> wrapper. That will cause nested/duplicated sidebars and headers when routed under the /$package layout. The child route component should usually render only the inner content (e.g., PluginHost) and rely on /$package for the shared layout, or alternatively remove the layout wrapper from /$package and keep it only in leaf routes.

TanStackRouterDevtools is rendered unconditionally. This typically pulls dev-only code into production bundles. Consider rendering it only in dev (e.g., if (import.meta.env.DEV)) or behind a feature flag.

The relative imports look incorrect for this file's location (apps/studio/test/plugins/...): ../src/... resolves to apps/studio/test/src/... which doesn't exist. Also, the test uses PluginRegistry APIs that don't exist in the implementation (new PluginRegistry([plugins]), getAllPlugins, getPlugin, activateAll, getViewersForType). Update imports to point at ../../src/... (or use the @/* alias) and align the assertions with the actual registry API (register, activate, getPlugins, getViewers, etc.).
