Fixed! Removed the extra FORCE_JAVASCRIPT_ACTIONS_TO_NODE24 line from ci.yml and squashed all commits into one. PR is now focused only on CDN Cache-Control headers.

"Hi @Aamod007, Fixed all issues:
✅ Restored getSecondsUntilUTCMidnight and getSecondsUntilMidnightInTimezone — dynamic cache TTL working correctly
✅ Error responses (404/500) use no-cache
✅ Success responses use public, s-maxage=${secondsToMidnight}, stale-while-revalidate=86400
✅ All 205 tests passing
✅ escapeXML preserved
Could you please re-review,

Thank you!"

Pull request overview

This PR is intended to implement CDN-friendly Cache-Control headers for the /api/streak route to reduce repeated serverless invocations and GitHub API usage (Fixes #69).

Changes:

Removes/adjusts in-file comments and whitespace in app/api/streak/route.ts.
(Intended, per PR description/issue #69) Update caching strategy for successful and error responses, but the current diff does not yet apply the described s-maxage=14400 behavior.

Comments suppressed due to low confidence (1)

app/api/streak/route.ts:103

The Cache-Control logic here still uses a dynamic s-maxage=${secondsToMidnight} (until midnight) rather than the fixed s-maxage=14400 described in the PR and required by issue #69. As a result, the response header won’t match the expected public, s-maxage=14400, stale-while-revalidate=86400 value, and the related cache-control tests will also need updating to reflect the new fixed TTL.

    const secondsToMidnight = tzParam
      ? getSecondsUntilMidnightInTimezone(timezone)
      : getSecondsUntilUTCMidnight();
    const cacheControl =
      refresh || isRandomTheme
        ? 'no-cache, no-store, must-revalidate'
        : `public, s-maxage=${secondsToMidnight}, stale-while-revalidate=86400`;

Hi @Aamod007, Updated 500 error response to Cache-Control: public, s-maxage=60 as suggested by Copilot. All 205 tests passing. Could you please re-review? Thank you!

The PR description/Issue #69 calls for a fixed CDN cache TTL (s-maxage=14400) on successful responses, but the route still computes secondsToMidnight and sets s-maxage dynamically based on UTC/local midnight. This doesn't match the described behavior (and the current tests are still written around the midnight-based TTL).

    const secondsToMidnight = tzParam
      ? getSecondsUntilMidnightInTimezone(timezone)
      : getSecondsUntilUTCMidnight();
    const cacheControl =
      refresh || isRandomTheme
        ? 'no-cache, no-store, must-revalidate'
        : `public, s-maxage=${secondsToMidnight}, stale-while-revalidate=86400`;

The success response Cache-Control is still using a dynamic s-maxage=${secondsToMidnight}. The PR description/issue #69 call for a fixed s-maxage=14400 (4 hours) with stale-while-revalidate=86400; as-is the route won’t match the intended CDN caching behavior (and requires the midnight helper calculations).

    const secondsToMidnight = tzParam
      ? getSecondsUntilMidnightInTimezone(timezone)
      : getSecondsUntilUTCMidnight();
    const cacheControl =
      refresh || isRandomTheme
