* perf: pre-split route patterns and hoist URL split out of match loop
Route matching runs on every request and iterates all routes until a
match is found. Previously, matchPattern() re-split both the URL and
the pattern string on every iteration:
for (const route of routes) {
// url.split("/") — same URL, re-split every iteration
// pattern.split("/") — pattern never pre-computed
matchPattern(normalizedUrl, route.pattern);
}
For a 50-route app on a 404, that's 50 URL splits + 50 pattern splits
+ 50 Object.create(null) + 100 .filter(Boolean) calls.
Fix:
- Add `patternParts: string[]` to Route and AppRoute interfaces,
computed once at scan time
- Split the URL once in matchRoute/matchAppRoute before the loop
- Pass pre-split arrays to matchPattern instead of raw strings
- Apply the same optimization to generated production entries
(pages-server-entry.ts, app-rsc-entry.ts)
- Fix intercepting route lookup to use the new array-based API
* update entry-templates snapshots
