🎯 Changes

req.query values are typed string | string[] | undefined in Next API routes, so passing them straight to parseInt or a string[] method fails type-checking in auto-refetching, infinite-query-with-max-pages, load-more-infinite-scroll and pagination.

  • In the projects routes, parse cursor / page with parseInt only when it is a string. A missing or invalid value still falls back to 0.
  • In auto-refetching's data route, add the item only when add is a non-empty string, so a repeated ?add= no longer pushes an array into the list.

✅ Checklist

  • I have followed the steps in the Contributing guide.
  • I have tested code changes locally with pnpm run test:pr, or these tests do not apply to this pull request.
  • I have followed the AI contribution policy and fully understand the code in this pull request, including any code generated with AI assistance.

🚀 Release Impact

  • This change affects published code, and I have generated a changeset.
  • This change is docs/CI/dev-only (no release).

Summary by CodeRabbit

  • Bug Fixes
    • Pagination and infinite-scroll examples now use the default starting value when page or cursor is not provided as a string. String values continue to be parsed, with invalid or zero results falling back to the default.
    • The auto-refetching example now adds an item only when add is a nonempty string and the item is not already in the list. Otherwise, the clear option remains the fallback.

Walkthrough

Four React example API handlers now check query value types before processing them. The auto-refetching handler processes additions only for nonempty string values. Three project handlers parse page or cursor values only when those values are strings.

Changes

React example API query handling

Layer / File(s) Summary
Add value handling
examples/react/auto-refetching/src/pages/api/data.ts
The handler processes additions only when add is a nonempty string. It retains the duplicate check and the existing clear fallback.
Numeric query parsing
examples/react/infinite-query-with-max-pages/src/pages/api/projects.ts, examples/react/load-more-infinite-scroll/src/pages/api/projects.ts, examples/react/pagination/src/pages/api/projects.ts
The handlers parse cursor or page only when the query value is a string. Other value types use zero. String values retain the existing parseInt conversion and falsy-result fallback.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~10 minutes

Change: Bug fix



Merge Risk: ⚪ Minimal · up to 443c0

This change only tightens query value handling in example API routes so they type-check. Behavior for valid inputs is preserved, and no merge-blocking risk remains.

- Line 12: Update the add branch condition to require that add is a non-empty
string while retaining the existing type check. This keeps an empty add value
from changing list and allows the clear branch to run when both add and clear
are supplied.

Review comments at
@examples/react/infinite-query-with-max-pages/src/pages/api/projects.ts:
- Line 4: Update the cursor parsing in the projects handler and the
corresponding cursor and page parsing in the load-more-infinite-scroll and
pagination handlers to narrow array-valued query inputs before parsing them as
integers. Preserve the existing zero fallback for invalid or missing values so
pagination arithmetic uses integer inputs.
