Closes the parity gap on PR #4658. The original PR shipped sandbox-function
descriptors only; this commit adds the auto-wiring React's CopilotKitProvider
performs when openGenerativeUI is configured:
- GenerateSandboxedUiArgsSchema, OpenGenerativeUIContentSchema, and the
OpenGenerativeUIActivityType / DEFAULT_DESIGN_SKILL constants ported from
React verbatim.
- CopilotOpenGenerativeUIToolRenderer Angular component — placeholder
message cycler matching the React tool renderer.
- CopilotOpenGenerativeUIRenderer Angular component — full activity
renderer with throttled streaming updates, preview + final websandbox
iframes, jsFunctions/jsExpressions execution with pending queue,
postMessage-based auto-height, and localApi bridge sourced from the
CopilotKit service's sandboxFunctions signal.
- processPartialHtml + extractCompleteStyles helpers for safe partial
innerHTML injection.
- CopilotKit service auto-registers the generateSandboxedUi frontend tool
and design-skill agent context (with override) when openGenerativeUI is
configured. Built-in activity renderers are exposed via a new
builtInActivityRenderers signal so a chat view (or follow-on renderer
registry) can mount the activity renderer for incoming activity messages.
16 new tests across process-partial-html.spec.ts and sandbox-functions.spec.ts.
Mirror React's openGenerativeUI.sandboxFunctions wiring on the Angular SDK.
Adds the SandboxFunction type and OpenGenerativeUIConfig to the Angular
public API, exposes configured functions as a readonly signal on the
CopilotKit service plus an injectSandboxFunctions() factory, and registers
the same JSON-schema agent context as CopilotKitProvider so the LLM can
invoke them from generated sandboxed UI.
Picks up ag-ui-protocol/ag-ui#1578 — `import * as jsonpatch from
"fast-json-patch"` produced an empty namespace under Node native ESM
because fast-json-patch@3.x populates exports via Object.assign, which
the CJS→ESM named-export detector cannot see. Result: every STATE_DELTA
and ACTIVITY_DELTA event threw "applyPatch is not a function", and
LangGraph generative UI streams floods the console with the failure on
each patch.
0.0.53 switches to a default import so the emitted bundle works under
both ESM and CJS consumers. Bumped @ag-ui/core and @ag-ui/encoder in
lockstep since they share the release.
Attachment queue & previews:
- Image lightbox with View Transition API morph animation
- Video lightbox with native controls and play button overlay
- Document lightbox (PDF via blob URL, text inline, info card fallback)
- Drop zone overlay with upload icon
- Filename preservation via InputContent metadata
- Proper video thumbnail sizing and play/pause indicator
- Fix attachment queue positioning (max-w-3xl constraint)
- Padding between X button and content for audio/document cards
- Document filenames wrap instead of truncating
Attachments config:
- onUploadFailed callback for validation/upload errors (file-too-large, invalid-type, upload-failed)
- onUpload accepts sync or async returns
- AttachmentUploadResult discriminated union with explicit interfaces
- Metadata field on Attachment and onUpload return type
AG-UI version bump:
- Bump @ag-ui/client, @ag-ui/core, @ag-ui/encoder, @ag-ui/proto to 0.0.51
- Remove process.env Vite workaround (fixed upstream in 0.0.51)
Deprecation lifecycle:
- @deprecated JSDoc on all legacy image upload APIs
- ImageRenderer, ImageRendererProps, ImageUpload type, imageUploadsEnabled prop,
inputFileAccept prop, ImageRenderer prop, AIMessage.image, ImageData
- Codemod at codemods/migrate-attachments.ts (15 tests)
- Migration guide updated with codemod instructions and new type shapes
Docs:
- New guide: docs/(root)/multimodal-attachments.mdx
- Updated migration guide with onUpload return type, metadata, codemod section
- Cross-links from prebuilt-components and migration guide
- Label change: "Add photos or files" → "Add attachments"
Tests:
- CopilotChat.attachments.test.tsx — 5 tests for onUploadFailed
- migrate-attachments codemod — 15 tests
Replace eslint and prettier with oxlint and oxfmt for faster linting
and formatting across the monorepo. Remove all eslint and prettier
configs, dependencies, and related packages. Add .oxlintrc.json and
.oxfmtrc.json for the new tooling. Update CI workflows and lefthook
hooks accordingly. Reformat codebase with oxfmt.

The previous publish workflow released 1.55.0-next.8 to npm but the
post-release commit failed to push to main (blocked by branch
protection). This applies the version bumps and pre.json updates that
the workflow would have committed, unblocking future releases.

After the V1/V2 consolidation merge, several changesets still referenced
old @copilotkitnext/* package names that no longer exist. Fixed package
references and ran changeset version to apply pending version bumps.

Flatten all packages from packages/v1/* and packages/v2/* into packages/* —
every package now lives directly under the @copilotkit/ scope with no v1/v2
subdirectories.
- Move all v1 packages (react-core, react-ui, runtime, shared, etc.) from
packages/v1/* to packages/*
- Absorb v2 react code into packages/react-core/src/v2/ (exported via /v2 subpath)
- Absorb v2 agent code into packages/runtime/src/agent/ (exported via /v2 subpath)
- Move v2 packages (core, angular, demo-agents, etc.) to packages/*
- Replace all @copilotkitnext/* imports with @copilotkit/* equivalents
- Keep @copilotkitnext/angular as the sole exception (angular remains on next)
- Update CI workflows, renovate config, release scripts for flat structure
- No public API surface changes — all exports fields are preserved
