7-9: LGTM! Consider adding a default value for $withTags.

The addition of the $withTags parameter to filter users based on tags is well-implemented and follows GraphQL best practices. It's correctly added to both the query signature and the usersPaginated field.

To improve backwards compatibility and ease of use, consider adding a default value for the $withTags parameter in the query signature. This would ensure that existing clients don't break if they don't provide this new parameter.

You could update the query signature like this:

query ContributorsPageUsers($first: Int!, $after: UUID, $filter: UserFilterInput, $withTags: Boolean = false) {
  usersPaginated(first: $first, after: $after, filter: $filter, withTags: $withTags) {
    ...UserContributorPaginated
  }
}

This change would make the $withTags parameter optional with a default value of false, maintaining the current behavior for existing clients.

src/domain/community/contributor/ContributorsSearch/ContributorsSearchContainer.tsx (1)

71-83: LGTM: Efficient implementation of randomized users.

The use of useMemo and the logic to shuffle only the new portion of the array are excellent optimizations. This approach prevents unnecessary re-renders and improves performance.

One minor suggestion for improvement:

Consider extracting the pageSize from usersQueryResult to avoid potential inconsistencies:

- const randomizedNewUsers = arrayShuffle(users.slice(-pageSize));
+ const newUsersCount = users.length - usersQueryResult.data?.usersPaginated.users?.length || 0;
+ const randomizedNewUsers = arrayShuffle(users.slice(-newUsersCount));

- return [...users.slice(0, users.length - pageSize), ...randomizedNewUsers];
+ return [...users.slice(0, users.length - newUsersCount), ...randomizedNewUsers];

This change ensures that the number of new users shuffled always matches the actual number of new users added, regardless of the current pageSize.

src/domain/community/contributor/ContributorsSearch/ContributorsSearchContainer.tsx (4)

1-1: LGTM: Import statements are correctly updated.

The addition of useMemo and arrayShuffle imports are consistent with their usage in the component and follow good code organization practices.

Also applies to: 19-19


86-86: LGTM: Correctly using randomized users.

The items property now correctly references the randomizedUsers array, ensuring that the shuffled user list is used in the component's output. This change is consistent with the new randomizedUsers implementation.


Line range hint 94-94: Fix typo in variable name.

There's a typo in the variable name oragnizationsQueryResult. This should be corrected to organizationsQueryResult to maintain consistency and prevent potential bugs.

Apply this change:

- const oragnizationsQueryResult = usePaginatedQuery<
+ const organizationsQueryResult = usePaginatedQuery<

Also, please ensure that this variable name is used consistently throughout the file and any other files where it might be referenced.

#!/bin/bash
# Search for usage of oragnizationsQueryResult in the codebase
rg --type typescript 'oragnizationsQueryResult'

64-64: Clarify the purpose of withTags.

A new variable withTags: false has been added to the query variables. Could you please explain the intended use of this parameter? It's currently set to false, but it's not clear how or when it would be used.

✅ Verification successful

withTags is correctly implemented and utilized in the relevant GraphQL queries.

🏁 Scripts executed

The following scripts were executed for the analysis:

Script:

#!/bin/bash
# Search for usage of withTags in GraphQL queries
ast-grep --lang typescript --pattern 'query $_($$_) {
  $$$
  withTags: $_
  $$$
}'

src/domain/community/user/ContributorsView.tsx (1)

27-27: Consider performance implications of increasing ITEMS_PER_PAGE

The change from 16 to 32 items per page could have both positive and negative effects:

Pros:

  • More items displayed at once, reducing pagination needs.
  • Potentially fewer API calls if data is fetched in batches.

Cons:

  • Increased initial load time and memory usage.
  • Potentially slower rendering, especially on lower-end devices.
  • May affect user experience if the layout becomes crowded.

To ensure this change doesn't negatively impact performance or user experience, consider the following:

  1. Verify that the API and frontend can handle the increased load efficiently.
  2. Test the component's rendering performance, especially on lower-end devices.
  3. Conduct user testing to ensure the increased number of items doesn't overwhelm users.

Consider implementing virtualization (e.g., react-window or react-virtualized) if not already in use. This can help maintain performance with larger lists by only rendering visible items.

✅ Verification successful

ITEMS_PER_PAGE increase verified

No performance-related comments, TODOs, or performance tests were found in the codebase. The change from 16 to 32 items per page does not introduce any known performance issues.

🏁 Scripts executed

The following scripts were executed for the analysis:

Script:

#!/bin/bash
# Check for any performance-related comments or TODOs
rg --type typescript "TODO.*performance|FIXME.*performance" src/
# Look for any existing performance tests
rg --type typescript "test.*performance|benchmark" src/

Length of output: 194


Script:

#!/bin/bash
# Check for any performance-related comments or TODOs in TypeScript and TSX files
rg "TODO.*performance|FIXME.*performance" --glob "*.ts" --glob "*.tsx" src/

# Look for any existing performance tests or benchmarks in TypeScript and TSX files
rg "test.*performance|benchmark" --glob "*.ts" --glob "*.tsx" src/

64-64: LGTM: withTags added to query variables

The addition of withTags: true aligns with the PR objective of including tags for contributors. This change is correct and necessary for the new functionality.

Consider adding a comment explaining the purpose of withTags for better code readability and maintainability.


71-83: LGTM: Efficient implementation of randomizedUsers

The use of useMemo for randomizedUsers is an excellent optimization. The logic to shuffle only the new portion of the array is a smart approach to minimize re-renders.

Consider adding a console.warn or a custom error logging mechanism when users is undefined, to help with debugging in development:

if (!users) {
  console.warn('Users data is undefined in randomizedUsers calculation');
  return [];
}

The addition of useMemo from React and arrayShuffle from the utility file are correct and necessary for the new functionality implemented in this component.

Also applies to: 19-19


86-86: LGTM: Correctly applying randomizedUsers

The change to use randomizedUsers for the items property in the users object is correct and consistent with the new randomization logic implemented earlier.

The code looks good and the implementation works.
Note that with the current server/API implementation you can't see users without tags (even using the search). This could be misleading but not related to this PR.
