Thorough Code Review Below is a detailed review with insights on:
Overall Structure & Best Practices Maintainability & Readability Functionality & Performance Error Handling & Edge Cases Security Considerations Where possible, I also provide pros and cons or potential alternative approaches.
- Overall Structure & Best Practices Single-File Component (SFC) Organization
You have the
You're using the ref(), computed(), and onMounted() from Vue, which is the recommended approach in Vue 3. The code is largely consistent with best practices for the Composition API. Quasar Integration
You import Quasar components like
You use the useAccountStore() to retrieve user data (e.g., accountName, isAuthenticated, user.transact()). The usage is idiomatic. Folder Structure
Imports like import { api } from 'src/api'; and import { Error, Proposal, RequestedApprovals } from 'src/types'; suggest a well-organized project. Typically, the api/, stores/, and types/ directories are good ways to structure domain concerns. Recommendation
Consider separating large API calls (handleMultsigTransaction, handleTransactionHistory) into a dedicated composition function or a pinia action if it’s used across multiple views. This will reduce the size of this single component. The component’s logic is quite large; factoring out certain chunks into helper files can keep the component lean. 2. Maintainability & Readability Naming & Comments
Variable names like proposalName, proposer, isExecuted, isCanceled are clear. Functions like handleRequestedApprovals, handleMultsigTransaction, and loadProposalAndUpdateFields are well-named, which enhances readability. The usage of inline comments helps to clarify decisions (like the original comment explaining why you do not automatically do a “2/3 + 1” check for BPs). State Variables
The code tracks several pieces of boolean state: hasUserAlreadyApproved, isExecuted, isCanceled, etc. This is generally fine, but watch out for possible confusion or interplay between them. isApproved.value = true; is set unconditionally after a comment. If the logic is incomplete or a placeholder, consider clarifying it further. If it’s purely for demonstration, it might confuse future maintainers, who would expect logic to decide that isApproved is actually true or false. Computed Properties
isShowApproveButton, isShowUnapproveButton, etc. are a nice approach to keep template logic clean. producersApprovalStatus is computed as X/Y—straightforward for users to see. Code Splitting
If the file grows further, you might want to keep all transaction and proposal logic in a separate file (or a composition function) and just import the relevant functions in your
Revisit isApproved.value = true;. If your real logic is more nuanced, consider implementing it or adding a TODO comment to clarify. Having a hidden or confusing override might lead to bugs. 3. Functionality & Performance API Calls
api.getProposals, api.getActions, api.getTransaction, api.getBlock are all asynchronous and used carefully with await. The code tries to fetch the correct action with a loop that increments actionSkip if the action isn’t found. This is a bit unorthodox but presumably addresses a real scenario where the relevant propose action might be outside the default pagination size. It’s fine, but watch out for performance if proposals are extremely large or if your queries keep skipping at large intervals. This might be a performance bottleneck if the relevant action is far in the chain. Repeatedly calling api.getActions in a while (typeof action === 'undefined') {...} might risk indefinite loops if no action is ever found. You have a console.error(e) but no break condition for a certain large skip. In a worst-case scenario, it might keep calling until it hits thousands of records. Consider adding a safety limit or a user notification that the action was not found. Moment.js
moment() usage is correct for checking if a proposal is expired. You only do a straightforward comparison, so it’s probably not a large performance cost. If moment isn’t used extensively across your project, you could consider alternatives like Date or smaller libraries (e.g., dayjs). However, for large ecosystems (like block explorers), moment is still a popular option. Deserialization of Actions
The approach for using setAbiCache is good: once you decode an ABI, you reuse it. This prevents multiple API calls. The approach of using the Serializer to objectify the actions is consistent with your stack (@wharfkit/session + @wharfkit/antelope). Recommendation
Add a safeguard in the while (typeof action === 'undefined') loop to avoid unbounded iteration—maybe break after actionSkip surpasses a certain threshold or re-check if the api.getActions indicates there are no more actions beyond that skip. Otherwise, a user might face a never-ending spinner if no match is found. 4. Error Handling & Edge Cases User Notifications
handleError(e, defaultMessage) is a nice consolidated approach that uses $q.notify. Good job centralizing error reporting. There’s a fallback await router.push('/proposal') in some error scenarios, which is user-friendly, ensuring the user doesn’t get stuck. For silent or unexpected errors, you log them to console.error(e), which can be helpful in debugging. That said, if this is production code, you may want to log them more comprehensively (or track them in a logging service). Validation
The code somewhat relies on API calls to verify the existence of proposals. If proposal comes back undefined, you push the user away from the page. That’s a valid approach. For some usage of big numbers (e.g., block number), it’s presumably handled by api.getBlock(String(blockNumber)). If it doesn’t exist, an error is triggered, and handleError is called. Possible Race Conditions
Because of multiple concurrent await calls in loadProposalAndUpdateFields, you rely on them returning. That’s typically fine for single-threaded JS. However, if the user navigates away mid-fetch, you might want to handle cancellation. In Vue 3, you can add an onBeforeUnmount to handle that, or you can rely on your fetch library to handle cancellation if needed. This might be an over-optimization, but it’s something to keep in mind for a large-scale block explorer. Recommendation
Verify whether you need a maximum iteration limit in your handleMultsigTransaction loop to guard against unexpected data or huge skip increments. For a polished product, consider a more user-friendly message for indefinite loops or missing data. 5. Security Considerations Transacting & Permissions You use accountStore.user.transact with explicit authorization (actor, permission). That’s a standard approach in EOSIO-based chains. On the front end, ensure that the user’s permission level is correct. If you rely on the store, be sure that the store properly checks for valid session or tokens. SHA-256 The usage of fast-sha256 for hashing code blocks is straightforward. You show the hex representation in the UI. That’s a read-only usage, so minimal risk. User Input Since the user can sign transactions (like Approve, Unapprove), any malicious or out-of-scope usage is presumably governed by wharfkit + the chain’s permission system. On the front end, you appear to treat user interactions as triggers for chain actions. That’s expected. Recommendation
Ensure that your chain or anchor plugin usage has tested the “reject transaction” scenario or invalid signature scenario, so that your UI gracefully handles it. This might already be covered, but keep in mind for robust error handling. Summary Pros
The code is well-organized, with a good logical flow. Proper usage of Vue 3 Composition API, Quasar components, and Pinia store. Clear variable naming and computed properties keep the template more readable. Good handling of asynchronous calls, plus graceful error handling with $q.notify. Good caching logic for ABIs, limiting repeated calls. Cons / Potential Improvements
The component is large; consider splitting out some logic (transaction fetching, proposal loading) into a separate composable or store method for cleaner code. isApproved.value = true; is effectively a placeholder—if real logic is needed, you should re-introduce or properly document how you decide a proposal is fully approved. The loop that calls getActions with incremental skipping can become unbounded if the relevant action is never found. A safe iteration limit or a fallback check is recommended. If you do not genuinely require all of Moment.js’s features, you could use a smaller library or native date comparisons. But if you have many date/time needs, moment is fine. Overall, the code demonstrates a solid command of Vue, Quasar, and the EOSIO environment. The main takeaways are structural improvements (breaking out logic) and small risk mitigations (loop safeguards, properly finishing the isApproved logic). Otherwise, it looks like a straightforward, well-reasoned approach for a block explorer’s proposal details page.
