feat: add @copilotkit/react-native package by mxmzb · Pull Request #3633 · CopilotKit/CopilotKit

Summary

Extract CopilotKitContext and useCopilotKit into standalone context.ts in react-core, enabling cross-platform reuse without web dependencies
Add new @copilotkit/react-native package with lightweight provider, polyfills, and streaming fetch
All hooks (useAgent, useFrontendTool, useHumanInTheLoop, etc.) are re-exported directly from react-core — no reimplementation

Motivation

CopilotKit's React hooks are platform-agnostic, but the barrel import in @copilotkit/react-core pulls in web-only dependencies (Radix UI, Lit, A2UI renderer, react-dom, CSS). This makes the package unusable in React Native without extensive Metro shimming.

By extracting the React context into a standalone entry point (@copilotkit/react-core/v2/context), the new @copilotkit/react-native package can provide its own lightweight provider while reusing all existing hooks.

What's in `@copilotkit/react-native`

Export	Description
`CopilotKitProvider`	Lightweight provider — no DOM, CSS, Radix, Lit, or A2UI deps
`installStreamingFetch()`	XHR-based streaming fetch for `response.body.getReader()` support
`@copilotkit/react-native/polyfills`	ReadableStream, TextEncoder, crypto, DOMException, window.location
`useAgent`, `useFrontendTool`, etc.	Re-exported from react-core (shared context)

Usage

// index.js (entry point, before other imports)
import "@copilotkit/react-native/polyfills";
import { installStreamingFetch } from "@copilotkit/react-native";
installStreamingFetch();

// App.tsx
import { CopilotKitProvider, useAgent, useCopilotKit } from "@copilotkit/react-native";

function App() {
  return (
    <CopilotKitProvider runtimeUrl="https://your-server/api/copilotkit">
      <ChatScreen />
    </CopilotKitProvider>
  );
}

Test plan

nx run react-core:build passes
nx run @copilotkit/react-native:build passes
nx run react-core:test — all 952 tests pass
Manual test in React Native app (tested during development with bare RN 0.84 project)

…build The headless build entry intentionally inlines @copilotkit/* packages via noExternal. tsdown detects their transitive deps (partial-json, phoenix, @standard-schema/spec) in the bundle and escalates the warning to an error when CI=true, failing the build. Setting inlineOnly: false acknowledges this is intentional. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

commit: 8d736e4

…, merge subscriptions - Keep abort signal listener active after headers arrive so mid-stream abort works correctly (previously disconnected too early, breaking agent cancellation) - Reject fullTextPromise in ReadableStream cancel() to prevent hanging .text()/.json() calls after stream cancellation - Add cleanupAbortListener() call in onAbort to prevent memory leaks - Extract fail() helper and createAbortError() to deduplicate 5 identical error-handling sequences across XHR event handlers - Add StreamingFetchResponse interface to replace `any`-typed response - Remove __DEV__ guard from insecure crypto polyfill warning so it appears in production logs - Merge two useEffect subscriptions (tool execution + error) into one Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

…olyfills Add comprehensive test suite for @copilotkit/react-native covering: - streaming-fetch.ts (36 tests): feature detection, request lifecycle, streaming chunks, convenience methods, abort handling, error paths - CopilotKitProvider.tsx (18 tests): initialization, prop sync, context provision, tool execution tracking, error forwarding, shape validation - polyfills.ts (20 tests): conditional installation, preservation of existing globals, crypto warning, streaming-fetch integration Also adds test infrastructure (vitest.config.mjs, setup.ts, devDependencies) and fixes an unhandled rejection bug in streaming-fetch where fullTextPromise could reject without a listener. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

…, clean up headless exports Move LicenseContext and useLicenseContext from CopilotKitProvider.tsx into context.ts so both web and RN providers share the same context singleton. Use import type for LicenseContextValue to avoid pulling @copilotkit/shared (and its Node-only jose dep) into the RN bundle at runtime. Also remove unused CopilotKitContext/useCopilotKit re-exports from headless.ts — the externalize-context tsdown plugin already handles these via relative imports.

…enseContext Address PR feedback from @AlemTuzlak: - Split monolithic polyfills.ts into individual imports (streams, encoding, crypto, dom, location) so users control what gets polyfilled - Remove auto-polyfill from index.ts — users explicitly import what they need - Add sideEffects array to package.json for bundler correctness - Wire LicenseContext.Provider into the RN CopilotKitProvider - Add new polyfill entry points to tsdown config and package.json exports - Use globalThis consistently (no more declare const global conflicts) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

…alias, simplify provider - Use `const g = globalThis as Record<string, unknown>` in polyfill files instead of repeating `(globalThis as any)` on every assignment line - Add `export {}` to polyfill files without imports so TS treats them as modules with isolated scope (prevents top-level variable collisions) - Document the pattern rationale in types.d.ts for future reference - Move shape validation from contextValue useMemo to one-time construction - Consolidate onAbort handler with centralized fail() function - Simplify onError event forwarding (pass event directly) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

…d, eliminate unsafe cast The headless build previously inlined @copilotkit/core via noExternal, creating a duplicate CopilotKitCoreReact class declaration in the .d.ts. Since the class has private members, TypeScript treated the two declarations as nominally distinct, forcing an `as unknown as CopilotKitContextValue` cast in the RN provider with runtime shape validation. @copilotkit/core has zero Node-only dependencies — the inlining was unnecessary. By keeping it external: - context.ts now value-exports CopilotKitCoreReact (was type-only import) - headless.ts re-exports from ./context (externalized to package path) - headless .d.ts references context's type → single declaration → no cast - RN provider uses plain typed code, no as-unknown-as, no shape validation - headless bundle is significantly smaller Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
