web/src/hooks/useTracking.ts (1)
6-13: Approve implementation with minor type safety improvementThe
useTrackinghook is well-implemented. It correctly usesuseEffectwith the appropriate dependencies and includes relevant information in the tracked event.For improved type safety, consider explicitly typing the
propsparameter:-const useTracking = (eventName: string, props?: object) => { +const useTracking = (eventName: string, props?: Record<string, unknown>) => {This change ensures that
propsis an object with string keys and values of any type, which is more precise than the generalobjecttype.web/src/components/ConnectWallet/index.tsx (3)
11-11: Approve usage of useTracking, but consider optimizing tracking.The useTracking hook is correctly implemented for the "Switch Network" action. However, it's currently tracking every render of the SwitchChainButton component, not just when the network is actually switched.
Consider moving the tracking to the handleSwitch function to only track when the user actually attempts to switch the network:
const handleSwitch = () => { if (!switchNetwork) { console.error("Cannot switch network. Please do it manually."); return; } try { switchNetwork(DEFAULT_CHAIN); useTracking("Switch Network", { success: true }); } catch (err) { console.error(err); useTracking("Switch Network", { success: false, error: err.message }); } };This change would provide more accurate tracking data and additional context about the success or failure of the network switch.
41-41: Approve usage of useTracking, but consider optimizing tracking and adding more context.The useTracking hook is correctly implemented for the "Connect Wallet" action, and including the chain object provides valuable context. However, it's currently tracking every render of the ConnectWallet component, not just when the wallet is actually connected or disconnected.
Consider the following improvements:
- Move the tracking to useEffect to track actual connection/disconnection events:
import { useEffect } from 'react'; // ... other code ... useEffect(() => { if (isConnected) { useTracking("Wallet Connected", { chain }); } else { useTracking("Wallet Disconnected", { chain }); } }, [isConnected, chain]);
- Add more context to the tracking event:
useTracking("Connect Wallet", { chain, isConnected, needsNetworkSwitch: isConnected && chain && chain.id !== DEFAULT_CHAIN });These changes would provide more accurate and detailed tracking data about wallet connection states and required actions.
Line range hint
1-50: Overall assessment: Good implementation with room for optimizationThe introduction of the useTracking hook enhances the component's ability to track user interactions. The implementation is correct and non-disruptive to the existing logic. However, there's potential to optimize when and how the tracking occurs to provide more accurate and detailed analytics data.
Consider implementing the suggested optimizations to improve the tracking functionality:
- Track the actual network switch action in SwitchChainButton.
- Use useEffect to track wallet connection/disconnection events in ConnectWallet.
- Include more detailed context in the tracking events.
These improvements will lead to more meaningful analytics data without significantly increasing the complexity of the components.
web/src/app.tsx (1)
Line range hint
1-43: Consider implementing privacy-conscious analytics tracking.While adding analytics can provide valuable insights, it's important to consider user privacy and comply with data protection regulations like GDPR or CCPA.
Consider implementing the following privacy-focused improvements:
- Add a mechanism to respect user preferences for analytics tracking (e.g., an opt-out option).
- Ensure that any personally identifiable information (PII) is properly anonymized before being sent to Mixpanel.
- Update your privacy policy to reflect the use of Mixpanel for analytics.
- Implement a consent management system if not already in place.
Example implementation for respecting user preferences:
import { useEffect } from 'react'; const App: React.FC = () => { useEffect(() => { const userAllowsTracking = /* logic to check user preference */; if (userAllowsTracking) { mixpanel.track("App Loaded"); } }, []); // ... rest of the component };web/src/components/ConnectWallet/AccountDisplay.tsx (2)
123-124: LGTM: User identification tracking added.The
useIdentifyhook is correctly implemented with the user's address. This addition enhances the application's ability to track user interactions without affecting the existing component functionality.Consider adding a comment explaining the purpose of the
useIdentifyhook for better code readability and maintainability. For example:// Track user identity for analytics useIdentify(address);
Line range hint
1-146: Summary: Mixpanel analytics integration successfully implemented.The changes in this file effectively integrate the Mixpanel analytics tracking by adding the
useIdentifyhook to theAddressOrNamecomponent. This implementation:
- Adds user identification tracking without altering the existing component logic.
- Is consistent with the PR objectives of enhancing analytics capabilities.
- Maintains the overall structure and readability of the code.
These modifications provide a solid foundation for tracking user interactions in the application.
As you continue to implement analytics throughout the application, consider creating a centralized analytics service or context to manage all tracking-related functionality. This approach can help maintain consistency and make it easier to update or replace the analytics provider in the future if needed.
web/src/pages/Cases/CaseDetails/Evidence/SubmitEvidenceModal.tsx (1)
86-90: Mixpanel tracking implementation looks good, with some suggestions for improvement.The tracking code is well-placed to capture successful evidence submissions. However, consider the following points:
Privacy: Tracking the full
pathnamemight expose sensitive information. Consider using a more generic identifier for the page or route.Code Structure: The tracking logic is nested within multiple callbacks. For better readability and easier error handling, consider extracting it into a separate function.
Here's a suggested refactor:
const trackEvidenceSubmission = (cid: string, evidenceGroup: bigint) => { mixpanel.track("submitEvidence", { page: "CaseDetails", // More generic than full pathname cid, evidenceGroup: evidenceGroup.toString(), // Convert BigInt to string for consistency }); }; // In the onClick handler: await wrapWithToast(async () => await walletClient.writeContract(request), publicClient).then( () => { trackEvidenceSubmission(cid, evidenceGroup); setMessage(""); close(); } );This refactor improves code readability, centralizes the tracking logic, and addresses the potential privacy concern.
web/src/pages/Courts/CourtDetails/StakePanel/StakeWithdrawButton.tsx (2)
91-94: Mixpanel tracking for increaseAllowance looks good.The implementation of Mixpanel tracking for the "increaseAllowance" event is well-done. It captures relevant information without exposing sensitive data. For consistency with other parts of the codebase, consider using a constant for the event name.
Consider defining a constant for the event name:
const INCREASE_ALLOWANCE_EVENT = "increaseAllowance"; // Then use it in the tracking call mixpanel.track(INCREASE_ALLOWANCE_EVENT, { // ... rest of the code });
112-117: Mixpanel tracking for setStake is well-implemented.The implementation of Mixpanel tracking for the "setStake" event is comprehensive and captures relevant information without exposing sensitive data. Here are a few suggestions for improvement:
- For consistency, consider using a constant for the event name, similar to the suggestion for "increaseAllowance".
- The stakeChange calculation could be made more readable by extracting it to a separate variable.
Consider applying these changes:
const SET_STAKE_EVENT = "setStake"; const stakeChangeAmount = (isStaking ? "" : "-") + parsedAmount.toString(); mixpanel.track(SET_STAKE_EVENT, { pathname: window.location.pathname, action: isStaking ? "stake" : "withdraw", courtId: id, stakeChange: stakeChangeAmount, });This improves readability and maintains consistency with the event naming convention.

Improve error handling, remove unused parameter, and check crypto availability
The useIdentify hook has a good foundation, but there are several areas for improvement:
- Error handling: Add try-catch block to handle potential errors in the hashing process.
- Unused parameter: The
propsparameter is currently unused. Either use it or remove it. - Crypto availability: Check for the availability of the
cryptomodule before using it.
Here's a suggested implementation addressing these points:
export const useIdentify = (userId: string | undefined) => {
useEffect(() => {
if (userId && typeof crypto !== 'undefined') {
try {
const hashedUserId = crypto.createHash("sha256").update(userId).digest("hex");
mixpanel.identify(hashedUserId);
} catch (error) {
console.error("Error identifying user:", error);
}
}
}, [userId]);
};This implementation:
- Adds a try-catch block for error handling.
- Removes the unused
propsparameter. - Checks for the availability of the
cryptomodule before using it.
Note: If you plan to use the props parameter in the future, keep it but add it to the dependency array of useEffect.

🛠️ Refactor suggestion
Consider refining the data passed to useTracking.
While the useTracking hook is correctly implemented, consider refining the data passed to it. Currently, all component props are being tracked, including function props like setCurrentPage. It's recommended to only track relevant data to avoid unnecessary overhead and potential issues with serializing function props.
For example, you might want to track only the following:
useTracking("CasesDisplay", {
currentPage,
numberDisputes,
casesPerPage,
title,
});This would provide meaningful analytics without including potentially sensitive or unnecessary data.

Consider optimizing the Mixpanel tracking call.
While adding analytics is beneficial, the current implementation may lead to excessive tracking. The "App" event will be logged on every render of the App component, which could result in redundant data and potentially impact performance.
Consider the following improvements:
- Use a more descriptive event name, e.g., "App Loaded" or "App Rendered".
- Implement a mechanism to track only on initial load or at a reasonable interval. For example:
import { useEffect } from 'react';
const App: React.FC = () => {
useEffect(() => {
mixpanel.track("App Loaded");
}, []); // Empty dependency array ensures this runs only once on mount
// ... rest of the component
};- If you need to track re-renders, consider adding more context to the event, such as the reason for the re-render or the current app state.

Consider moving crypto-browserify to dependencies
The addition of crypto-browserify suggests that the project needs cryptographic functionality in a browser environment. However, it's unusual to see this as a devDependency. If this package is used at runtime (which is typically the case), it should be moved to the dependencies section instead.

🛠️ Refactor suggestion
Consider relocating the Mixpanel utility for better organization.
The current import statement uses a relative path that goes up four directory levels. This might indicate that the Mixpanel utility could be placed in a more accessible location within the project structure. Consider moving it to a common utilities folder that's easier to access from various parts of the application.
