73-106: Improve error handling and fix variable shadowing in the GPT exampleThe example code has several issues that should be addressed:
- The
responsevariable is shadowed- Missing error handling for API calls
- Conversation history could grow unbounded
Here's the suggested improvement:
const onMessage = async (message, user) => { console.log(`Decoded message: ${response} by ${user}`); // Prepare conversation history or context as needed const history = [ { role: "system", content: "You are a helpful assistant." }, { role: "user", content: message }, ]; // Call the OpenAI API to process the user's message - const response = await openai.createChatCompletion({ - model: process.env.GPT_MODEL || "gpt-4", - messages: history, - }); + try { + const completion = await openai.createChatCompletion({ + model: process.env.GPT_MODEL || "gpt-4", + messages: history, + }); - const response = response.data.choices[0].message.content.trim(); + const aiResponse = completion.data.choices[0].message.content.trim(); - // Send the AI-generated response back to the XMTP network - xmtp.send({ - message: response, - originalMessage: message, - }); + // Send the AI-generated response back to the XMTP network + await xmtp.send({ + message: aiResponse, + originalMessage: message, + }); + } catch (error) { + console.error('Error processing message:', error); + // Handle error appropriately + } };

116-183: Improve React hooks implementation and error handlingThe React example needs several improvements for production readiness:
- Add cleanup in useEffect:
useEffect(() => { const init = async () => { try { if (user?.address) { await initXmtp(newWallet); } } catch (error) { console.error("Error resolving recipient:", error); setIsLoading(false); } }; init(); + return () => { + // Cleanup XMTP connection + xmtp?.disconnect(); + }; -}, [user.address]); +}, [user.address, newWallet]);
- Add loading state handling:
- return <div className={styles.chatContainer}>{/* Render chat UI */}</div>; + if (isLoading) { + return <div>Connecting to XMTP...</div>; + } + + if (!xmtp) { + return <div>Failed to connect to XMTP</div>; + } + + return ( + <div className={styles.chatContainer}> + {/* Render chat UI */} + </div> + );
- Improve error handling in message sending:
const sendMessage = async (e: React.FormEvent) => { e.preventDefault(); - if (!xmtp || !newMessage || !recipientInfo?.address) return; + if (!xmtp || !newMessage?.trim() || !recipientInfo?.address) { + console.warn('Missing required fields for sending message'); + return; + } try { const message = await xmtp.send({ message: newMessage, receivers: [recipientInfo.address], }); setMessages((prevMessages) => [...prevMessages, message]); setNewMessage(""); } catch (error) { console.error("Error sending message:", error); + // Show user-friendly error message + // Handle specific error cases (network issues, etc.) } };

361-361: Consider using a structured logging mechanism overconsole.log.Currently, the stream’s progress is logged as an informational statement. While this change clarifies that it’s not a warning, you could benefit from using a structured logging library to manage verbosity levels consistently across the application.
391-391: Same suggestion here for logging.The logging for the v2 stream now also indicates that it’s started. Ensure that both v3 and v2 streams use consistent logging approaches (levels, format, etc.) for easier debugging and monitoring.

111-115: Add package version constraints and feature limitationsThe package introduction should specify:
- The recommended version range
- Clear feature limitations (e.g., no group support)
-xmtp-e2ee is a light wrapper around the xmtp package to make it easier to use in react and web. Doesnt support groups yet. +xmtp-e2ee is a lightweight wrapper around the xmtp package that simplifies React and web integration. + +> **Note**: This package currently has the following limitations: +> - No support for group messaging +> - Requires React 16.8+ for hooks support

116-183: Add security measures to the React implementationConsider implementing these security measures:
- Message validation:
const validateMessage = (message: string): boolean => { // Add size limits if (message.length > MAX_MESSAGE_LENGTH) return false; // Add content validation if (containsmaliciousContent(message)) return false; return true; };
- Rate limiting:
const sendMessage = async (e: React.FormEvent) => { e.preventDefault(); if (isRateLimited()) { console.warn('Message rate limit exceeded'); return; } // ... rest of the send logic };
- Consider implementing message encryption at rest if storing chat history locally.
Would you like me to provide a complete implementation of these security measures?

234-241: Consider refactoring the CSS to avoid !important flagsThe
.encryptionInfoclass uses multiple!importantflags which can lead to specificity wars and make the styles harder to maintain. Consider:
- Restructuring the CSS specificity to avoid
!important- Increasing the font size from
0.7remfor better readability- Using consistent padding values
.encryptionInfo { - text-align: center !important; - width: 100%; - font-size: 0.7rem; - padding: 0rem; - padding-top: 0.4rem; - display: block !important; + text-align: center; + width: 100%; + font-size: 0.8rem; + padding: 0.4rem 0 0; + display: block; }Additionally, consider adding these styles for better mobile responsiveness:
@media (max-width: 768px) { .encryptionInfo { font-size: 0.75rem; padding: 0.3rem 0 0; } }

11-11: Remove leftover property from the type definition for consistency.
urlTypeis no longer destructured, so consider removing it from the type definition altogether or confirm if it might be used elsewhere. This prevents confusion and keeps the component interface concise.You can apply the following diff:
-export const UrlPreview = ({ url }: { url: string; urlType?: string }) => { +export const UrlPreview = ({ url }: { url: string }) => {
