🔇 Additional comments (18)
src/components/Chart/Chart.jsx (1)
14-14: LGTM! Good formatting improvement.The added whitespace improves readability by visually separating the API call from the state update.
src/components/Cards/Cards.jsx (3)
1-4: LGTM! Good consistency improvement.Standardizing import statements to use double quotes improves code consistency across the project.
8-8: LGTM! Quote consistency maintained.Updated the loading message to use double quotes, maintaining consistency with the import statements.
13-15: LGTM! Better JSX formatting.The multi-line Typography component formatting improves readability compared to the single-line version.
src/components/Cards/Card/Card.jsx (2)
1-6: LGTM! Import consistency maintained.Good update to use double quotes consistently across all import statements.
8-40: LGTM! Excellent refactoring to explicit return.The refactor from implicit return arrow function to explicit return improves:
- Code readability and maintainability
- Debugging capabilities (easier to set breakpoints)
- Future extensibility (easier to add logic before return)
All functionality is preserved while improving code structure.
src/components/CountryPicker/CountryPicker.jsx (4)
1-6: LGTM! Import consistency maintained.Consistent use of double quotes across all import statements.
13-14: Excellent defensive programming!The
Array.isArray()check prevents potential runtime errors if the API returns unexpected data types. This defensive approach is crucial for deployment stability and aligns well with the PR's objective of fixing deployment issues.
26-26: Good UX improvement with "Global" default.Changing the default from "United States" to "Global" better reflects the app's international scope and aligns with the API's global data capabilities.
28-28: Better React key usage.Using the country name as the key instead of array index is a React best practice that prevents potential rendering issues when the list order changes.
src/App.js (3)
1-7: LGTM: Consistent import style applied.The transition to double quotes for import statements improves code consistency across the project.
11-18: LGTM: Improved initial state structure prevents potential runtime errors.The structured initial state with default values is a defensive programming practice that prevents undefined errors when child components access nested properties before data is fetched from the API.
27-28: LGTM: Modern ES6 shorthand property notation.Using shorthand property notation (
{ data, country }) is cleaner and more concise than the verbose form.README.md (1)
14-24: LGTM: Excellent documentation improvements.The new Tech Stack and Fixed Issues sections provide valuable information for users and contributors. The structured approach enhances the README's usefulness.
src/api/index.js (4)
6-9: LGTM: Clean API endpoint handling.The conditional logic properly handles both global and country-specific data requests with the new API structure.
13-27: LGTM: Improved error handling and data structure mapping.The changes provide several improvements:
- Data structure correctly maps new API fields to expected format
- Error handling now returns a sensible default object instead of raw errors
- Console logging helps with debugging deployment issues
This aligns well with the PR objective of fixing deployment errors.
42-55: LGTM: Consistent formatting and structure.The formatting improvements make the code more readable while maintaining the same functionality.
59-66: LGTM: Better error handling for country data.Returning an empty array on error instead of the raw error object is more appropriate for UI consumption and prevents potential rendering issues.

Fix heading level violation.
The heading level jumps from h1 to h3, which violates markdown best practices and accessibility guidelines.

Remove unused variable.
The url constant contains the old API endpoint but is no longer used after the migration to the new API.
Apply this diff to remove the unused variable:

In src/api/index.js at line 3, the constant `url` is declared but never used in
the code. Remove the entire line declaring `const url =
"https://covid19.mathdro.id/api";` to clean up the code and avoid unused
variables.

I have fixed the deployment issue (#59) in the Corona Tracker app.
The app is now deployed successfully on Netlify and works without errors.
Please review and let me know if any changes are needed.
