PR Reviewer Guide 🔍

⏱️ Estimated effort to review: 4 🔵🔵🔵🔵⚪

🧪 No relevant tests

🔒 No security concerns identified

⚡ Key issues to review Duplicate Code The error handling and Ethereum interaction functionalities are duplicated across multiple bundle files (transfer.bundle.js, profile.bundle.js, metamask.bundle.js, graph_query.bundle.js). Consider abstracting these functionalities into a shared module to reduce code duplication and improve maintainability. Error Handling The functions setRewardAsClaimed and checkRewardClaimed throw generic errors without specific messages. It's recommended to provide more descriptive error messages to help with debugging and user feedback. Configuration Clarity The Webpack configuration script uses dynamic entry points which might make the build process unclear or unpredictable. Ensure that the entry points are well-documented and consider simplifying the configuration if possible. Security Concern The private key is directly used in the Truffle configuration. It's recommended to use environment variables to manage private keys securely.

PR Code Suggestions ✨

Category	Suggestion	Score
Possible issue	Implement a retry limit or timeout for recursive calls to prevent potential infinite loops To avoid potential infinite loops and excessive CPU usage, consider implementing a maximum number of retries or a timeout mechanism in the recursive requestAnimationFrame call within the checkState function. assets/js/postquiz.js [184] -window.requestAnimationFrame(checkState); +if (retryCount < MAX_RETRIES) { + window.requestAnimationFrame(checkState); + retryCount++; +} else { + console.error('Max retries reached.'); + // Handle max retries situation, e.g., show error message +} Apply this suggestion Suggestion importance[1-10]: 10 Why: Implementing a retry limit or timeout for recursive calls is essential to prevent potential infinite loops, which can lead to excessive CPU usage and application crashes.	10
Best practice	Add error handling for asynchronous operations to improve robustness Implement error handling for asynchronous operations to catch and handle any exceptions that may occur during API calls or other asynchronous processes. dist/graph_query.bundle.js [1] -const t=await fetch(e,{method:"POST",headers:{"Content-Type":"application/json"},body:JSON.stringify({query:"\n {\n transfers(\n\t\t\t\t\t\t\t\t\t\torderBy: tokenId\n\t\t\t\t\t\t\t\t\t\torderDirection: desc\n\t\t\t\t\t\t\t\t\t\t)\n {\n\t\t\t\t\t\t\t\t\t\t\t\ttokenId\n\t\t\t\t\t\t\t\t\t\t\t\tfrom\n\t\t\t\t\t\t\t\t\t\t\t\tto\n\t\t\t\t\t\t\t\t\t\t\ttransactionHash\n\t\t\t\t\t\t\t\t\t\t\t\tblockTimestamp\n\t\t\t\t\t\t\t\t\t\t\t\tblockNumber\n }\n "})}); +try { + const t=await fetch(e,{method:"POST",headers:{"Content-Type":"application/json"},body:JSON.stringify({query:"\n {\n transfers(\n\t\t\t\t\t\t\t\t\t\torderBy: tokenId\n\t\t\t\t\t\t\t\t\t\torderDirection: desc\n\t\t\t\t\t\t\t\t\t\t)\n {\n\t\t\t\t\t\t\t\t\t\t\t\ttokenId\n\t\t\t\t\t\t\t\t\t\t\t\tfrom\n\t\t\t\t\t\t\t\t\t\t\t\tto\n\t\t\t\t\t\t\t\t\t\t\t\ttransactionHash\n\t\t\t\t\t\t\t\t\t\t\t\tblockTimestamp\n\t\t\t\t\t\t\t\t\t\t\t\tblockNumber\n }\n "})}); +} catch (error) { + console.error('Failed to fetch data:', error); +} Apply this suggestion Suggestion importance[1-10]: 9 Why: Adding error handling for asynchronous operations is crucial for robustness and reliability, making this a highly valuable suggestion.	9
	Use const for variables that do not change to enhance code reliability Use const for variables that are not reassigned to communicate immutability and prevent accidental reassignment, enhancing code reliability. dist/profile.bundle.js [1] -var t={165:(t,e,n)=>{n.d(e,{g:()=>s});... +const t={165:(t,e,n)=>{n.d(e,{g:()=>s});... Suggestion importance[1-10]: 8 Why: Using const for variables that do not change enhances code reliability and readability. This is a best practice that prevents accidental reassignment.	8
	Use const for variables that do not change to improve code reliability It's recommended to use const for variables that are not reassigned, such as address in the checkState function, to ensure they remain immutable where applicable, enhancing code reliability and readability. assets/js/postquiz.js [169] -let address = getState().account; +const address = getState().account; Apply this suggestion Suggestion importance[1-10]: 7 Why: Using const for variables that do not change improves code reliability and readability, although it is a minor improvement.	7
	Use const for variables that do not change to enhance code reliability Consider using const for variables that do not change after their initial assignment to ensure they are not inadvertently reassigned elsewhere in the code. dist/graph_query.bundle.js [1] -var t={390:(t,e,n)=>{n.d(e,{A:()=>s});const s=class{constructor(){this.injectErrorBlock(),this.trackErrors()}injectErrorBlock(){this.errorBlock=document.createElement("div"),this.errorBlock.classList.add("error-block"),document.body.appendChild(this.errorBlock)}errorElementConstructor({message:t,type:e}){const n=document.createElement("div");n.setAttribute("data-date",new Date),n.classList.add("error-container",e);const s=document.createElement("div");s.classList.add("error-element",e);const o=document.createElement("i"); +const t={390:(t,e,n)=>{n.d(e,{A:()=>s});const s=class{constructor(){this.injectErrorBlock(),this.trackErrors()}injectErrorBlock(){this.errorBlock=document.createElement("div"),this.errorBlock.classList.add("error-block"),document.body.appendChild(this.errorBlock)}errorElementConstructor({message:t,type:e}){const n=document.createElement("div");n.setAttribute("data-date",new Date),n.classList.add("error-container",e);const s=document.createElement("div");s.classList.add("error-element",e);const o=document.createElement("i"); Apply this suggestion Suggestion importance[1-10]: 6 Why: Using const for variables that do not change is a good practice for code reliability, but this suggestion addresses a minor improvement.	6
Enhancement	Simplify and enhance scalability by using a mapping object for class additions based on error types Replace the repetitive error type checks and class additions with a mapping object to reduce code redundancy and improve scalability. dist/profile.bundle.js [1] -"error"===e&&s.classList.add("fas","fa-exclamation-circle"),"warning"===e&&s.classList.add("fas","fa-exclamation-triangle"),"info"===e&&s.classList.add("fas","fa-info-circle"); +const iconClasses = { + error: ["fas", "fa-exclamation-circle"], + warning: ["fas", "fa-exclamation-triangle"], + info: ["fas", "fa-info-circle"] +}; +s.classList.add(...iconClasses[e]); Suggestion importance[1-10]: 9 Why: Using a mapping object for class additions based on error types simplifies the code and improves scalability. This significantly reduces redundancy and makes the code easier to maintain.	9
Possible bug	Add error handling for JSON parsing to prevent script execution stop on errors Consider adding error handling for the JSON.parse operation when retrieving the login data from sessionStorage. This operation can throw an exception if the item is not present or is not valid JSON, which would cause the script to stop executing. assets/js/postquiz.js [61] -login = JSON.parse(sessionStorage.getItem('login')); +try { + login = JSON.parse(sessionStorage.getItem('login')); +} catch (e) { + console.error('Failed to parse login data:', e); + // Handle error appropriately, e.g., redirect to login page or show an error message +} Apply this suggestion Suggestion importance[1-10]: 9 Why: Adding error handling for JSON parsing is crucial as it prevents the script from stopping execution due to malformed or missing data, enhancing the robustness of the application.	9
Maintainability	Reduce complexity and improve reuse by extracting error handling into a separate function Extract the error handling into a separate function to reduce complexity and improve code reuse. dist/transfer.bundle.js [1] -catch(t){throw o.v.errorDetection.consoleError(t.message),new Error(t)} +catch(t){handleError(t)} +function handleError(t) { + o.v.errorDetection.consoleError(t.message); + throw new Error(t); +} Apply this suggestion Suggestion importance[1-10]: 8 Why: Extracting error handling into a separate function can significantly reduce complexity and improve code reuse, making the code more maintainable and easier to understand.	8
	Centralize error handling to improve code organization and maintainability Replace inline error handling with a dedicated function to centralize error management and improve code organization. dist/profile.bundle.js [1] -throw s.v.errorDetection.consoleError(t.message),new Error(t) +handleError(t); +function handleError(error) { + s.v.errorDetection.consoleError(error.message); + throw new Error(error); +} Apply this suggestion Suggestion importance[1-10]: 8 Why: Centralizing error handling improves code organization and maintainability. This change makes the code cleaner and easier to manage, especially as the project grows.	8
	Reduce redundancy by refactoring repeated icon creation code into a method Refactor the repeated code for creating error, warning, and info icons into a separate method to reduce redundancy and improve code readability. dist/graph_query.bundle.js [1] -"error"===e&&o.classList.add("fas","fa-exclamation-circle"),"warning"===e&&o.classList.add("fas","fa-exclamation-triangle"),"info"===e&&o.classList.add("fas","fa-info-circle"); +this.addIcon(o, e); Apply this suggestion Suggestion importance[1-10]: 8 Why: Refactoring repeated code into a method enhances maintainability and readability significantly by reducing redundancy.	8
	Refactor the transaction handling to separate UI updates from transaction logic Refactor the transactNFT function to separate concerns more clearly by handling the transaction and UI updates in distinct functions or blocks of code. This improves maintainability and readability. assets/js/postquiz.js [188-205] try { await fundAccount(); const response = await setRewardAsClaimed({ gamePin, topicID, username, wallet }); + handleTransactionResponse(response); +} catch (error) { + handleTransactionError(error); +} + +function handleTransactionResponse(response) { navbar.errorDetection.consoleInfo(response.message); reload = false; tokenTransferred = true; navbar.errorDetection.consoleInfo('Token transfer successful'); - return 'status: success'; -} catch (error) { +} + +function handleTransactionError(error) { reload = false; if (error.code === 4001) { error.reason = prompt('Please state the reason for cancelling the transaction?'); navbar.errorDetection.consoleWarn('Transaction cancelled', error.reason); } else { navbar.errorDetection.consoleError('Error funding account', error); } } Apply this suggestion Suggestion importance[1-10]: 8 Why: Refactoring the function to separate transaction logic from UI updates enhances maintainability and readability, making the code easier to manage and understand.	8
	Improve maintainability by using class toggling instead of direct style manipulation Replace the direct manipulation of style properties with a class toggle to improve maintainability and separation of concerns. dist/transfer.bundle.js [1] -this.errorBlock.style.display="grid" +this.errorBlock.classList.add('visible') +this.errorBlock.classList.remove('hidden') Apply this suggestion Suggestion importance[1-10]: 7 Why: Using class toggling instead of direct style manipulation can improve maintainability and separation of concerns. However, the suggestion should ensure that the corresponding CSS classes ('visible' and 'hidden') are defined and used appropriately.	7
	Improve maintainability by using class manipulation instead of direct style changes Replace the direct manipulation of style.display with a more robust class-based approach to show or hide HTML elements. This makes the code easier to maintain and less error-prone by centralizing display logic in CSS. dist/profile.bundle.js [1] -o.style.display="none" +o.classList.add('hidden') Apply this suggestion Suggestion importance[1-10]: 7 Why: Using class manipulation instead of direct style changes improves maintainability and reduces the risk of errors. However, the impact is relatively minor as it only affects the display logic.	7
	Improve code maintainability by using CSS classes for style changes Replace the direct manipulation of styles and attributes with a more structured approach using CSS classes and data attributes. This will make the code cleaner and easier to maintain. dist/graph_query.bundle.js [1] -this.errorBlock.style.display="grid" +this.errorBlock.classList.add('visible') Apply this suggestion Suggestion importance[1-10]: 7 Why: Using CSS classes instead of direct style manipulation improves maintainability and readability. However, the suggestion only addresses a minor aspect of the code.	7
	Enhance code readability and maintainability using template literals Use template literals for constructing DOM elements to enhance readability and maintainability. dist/transfer.bundle.js [1] -t.innerHTML='<i class="fas fa-user"></i>' +t.innerHTML=`<i class="fas fa-user"></i>` Apply this suggestion Suggestion importance[1-10]: 6 Why: Using template literals can enhance readability and maintainability, but this change is relatively minor and does not significantly impact the overall functionality of the code.	6
