Fix crash when using @tailwindcss/vite using deno v2.8.x

[RobinMalfait]

This PR might fix an issue where resolvers don't work on deno v2.8.x (they do work on deno v2.7.x) when using @tailwindcss/vite.

This happens when the context.parentURL is not actually a URL at all, and therefore the new URL(…) just crashes. This PR will fallback to the incoming result for files that are not passed proper URLs.

Fixes: #20232

Test plan

1. Existing tests pass
2. Can't seem to figure out how to test this in the reproduction issue without publishing first. So going to merge this and test the insiders version instead.
3. Tested with the insiders build:

Deno v2.7:

Deno v2.8:

Deno v2.8 + @tailwindcss/vite@insiders:

[greptile-apps]

Confidence Score: 5/5

Safe to merge — the change is a minimal, well-scoped defensive guard that cannot regress existing behavior.

The fix wraps a two-line URL construction block in a try/catch and falls back to returning the unmodified resolver result on any exception. Every existing code path that succeeded before still succeeds; only the previously-crashing path now recovers gracefully. No logic is removed or reordered.

No files require special attention.

Walkthrough

The processResolve function in packages/@tailwindcss-node/src/esm-cache.loader.mts now wraps its URL rewriting logic—reading context.parentURL, manipulating search params, and constructing the return URL—in a try/catch block. On any exception, it returns the original unmodified result rather than propagating the error. The CHANGELOG.md adds a corresponding entry under [Unreleased] → Fixed noting that @tailwindcss/vite no longer crashes in Deno v2.8.x when context.parentURL is not a valid URL.

🚥 Pre-merge checks | ✅ 4

✅ Passed checks (4 passed)

Check name	Status	Explanation
Title check	✅ Passed	The title accurately and specifically describes the main fix: addressing a crash in @tailwindcss/vite when using Deno v2.8.x.
Description check	✅ Passed	The description explains the problem, solution, and references the linked issue #20232, providing context for the crash fix in @tailwindcss/vite under Deno.
Linked Issues check	✅ Passed	The code changes implement the required fix by wrapping URL parsing logic in try/catch to handle cases where context.parentURL is not a valid URL, directly addressing the regression in issue #20232.
Out of Scope Changes check	✅ Passed	All changes are scoped to fixing the crash: CHANGELOG.md documents the fix and esm-cache.loader.mts implements the fallback mechanism for invalid URLs.
