31-32: Verify OAuth token structure across all authentication flows
The token access path has been updated to match OAuth2 token structure. While this looks correct, please verify this works with all authentication flows.
✅ Verification successful
OAuth token structure is correctly implemented
The token access path oauthToken.token.access_token is consistent with:
- The imported
AccessTokentype fromsimple-oauth2 - The token usage in
ServerClientclass for Bearer authentication - The token refresh mechanism in
ensureValidOauthToken

🛠️ Refactor suggestion
Consider a more robust approach for handling browser APIs in Node.js
The current implementation adds global no-op event listeners, which could mask potential issues by silently ignoring events. Consider using a proper polyfill or environment-specific implementation.
-declare global {
- function addEventListener(type: string, listener: () => void): void
- function removeEventListener(type: string, listener: () => void): void

+import { EventEmitter } from 'events';
+
+class NodeEventAdapter extends EventEmitter {
+ addEventListener(type: string, listener: () => void): void {
+ this.on(type, listener);

+ }
+}
+
+const eventAdapter = new NodeEventAdapter();
+global.addEventListener = eventAdapter.addEventListener.bind(eventAdapter);
+global.removeEventListener = eventAdapter.removeEventListener.bind(eventAdapter);Also, fix the linting issues by adding semicolons:

- function removeEventListener(type: string, listener: () => void): void
+ function addEventListener(type: string, listener: () => void): void;

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

1-41: Consider a more robust server-side ActionCable implementationThe current implementation mixes browser and Node.js concepts in a way that could be fragile. Consider creating a proper server-side ActionCable adapter that:
- Doesn't rely on browser APIs (addEventListener/removeEventListener)
- Provides proper WebSocket error handling
- Has robust token validation
- Uses TypeScript's strict mode features for better type safety
This would make the code more maintainable and reliable.

7-10: Consider TypeScript's DOM lib types instead of global declarations
If these declarations are needed for DOM compatibility, consider using TypeScript's DOM lib types by adding "dom" to your tsconfig's lib array instead of declaring them globally. This provides better type safety and maintainability.
Let's check if DOM types are already included:
✅ Verification successful
Global declarations are correctly used for server-side environment compatibility
The global declarations of addEventListener and removeEventListener in packages/sdk/src/server/async.ts are intentionally implemented as no-op functions to provide compatibility with ActionCable in a server environment. This is evidenced by:
- The file is specifically for server-side async response management (
server/async.ts) - The implementations are minimal no-op functions:
global.addEventListener = () => {} - They are used alongside WebSocket adapters for ActionCable compatibility
- The browser version in
packages/sdk/src/browser/index.tscorrectly uses the actual window-based event listeners
🏁 Scripts executed
The following scripts were executed for the analysis:

#!/bin/bash
# Check tsconfig.json for DOM lib inclusion

Fix incorrect WebSocket adapter assignment
There's a potential bug in the WebSocket adapter assignment. The comparison operator == is used instead of the assignment operator =.
Apply this fix:
if (typeof adapters.WebSocket === "undefined")
- adapters.WebSocket == WS;
+ adapters.WebSocket = WS;Also applies to: 26-27

33-37: Verify OAuth token usage across the codebase
Let's verify how the OAuth token is used in other parts of the codebase to ensure this change doesn't break existing functionality.
✅ Verification successful
OAuth token access pattern is consistent across the codebase
The changes to OAuth token access in packages/sdk/src/server/async.ts follow the same pattern used in other files:
- The
getOauthTokeninterface is defined consistently in both async and regular server implementations - Token access follows the same structure (
oauthToken.token.access_token) in bothserver/index.tsandserver/async.ts - The error handling for invalid token structure adds a safety check without disrupting the existing pattern

🛠️ Refactor suggestion
Consider implementing a proper WebSocket adapter
The current type cast as unknown as WebSocket bypasses TypeScript's type checking, which could hide potential incompatibilities between the 'ws' package and the browser's WebSocket interface.
Consider implementing a proper adapter class:
class NodeWebSocketAdapter implements WebSocket {
private ws: WS;
constructor(url: string, protocols?: string | string[]) {
this.ws = new WS(url, protocols);
}
// Implement necessary WebSocket interface methods
get readyState(): number {
return this.ws.readyState;
}
close(code?: number, reason?: string): void {
this.ws.close(code, reason);
}
// ... implement other required methods
}
// Usage
adapters.WebSocket = NodeWebSocketAdapter;
