tryFetchManifestPair sceglie l'estensione in base a resolveJsonMode():
json5 -> .json5, legacy -> .json, auto -> entrambi. Evita le richieste
manifest.json fallite a ogni avvio in modalita json5.
Three improvements on top of duckietm/Dev's new JSON5 + split-aware
gamedata loader:
1. Parallel fetches inside loadGamedata: every file declared in a
tier's manifest is now fetched with Promise.all. The merge step
still walks the parts in declared order so override semantics
(core -> custom -> seasonal, and within-tier declaration order)
are preserved. Root-manifest files and per-tier manifest discovery
also run concurrently.
2. tryFetchManifest distinguishes 404 from other failures. The
previous tryFetchOrNull silently treated parse errors and 5xx as
"manifest missing", so a malformed manifest.json5 made an entire
tier vanish from the boot. Now only HTTP 404 returns null; every
other failure propagates.
3. New ConfigJsonError class with phase ('fetch' | 'parse'),
sourceUrl, and optional httpStatus. Exported isMissingResource()
helper lets callers check for 404 without string-matching.
Also:
- mergeGamedata warns via NitroLogger when an array looks keyed by
id/classname/name on >=80% of items but a few are missing the
key (the previous behavior fell back to concat() and produced
silent duplicates).
- Removed the dead text === null/undefined branch in parseConfigJson
(Response.text() never returns null).
Verified: tsgo clean, 138/138 tests pass on the renderer, 207/207
tests pass on the client (no behavioral change to existing callers).
Adds three explicit parsing strategies selectable at host build time via
the compile-time constant __NITRO_JSON_MODE__:
- legacy: strict JSON.parse only; clear error suggesting JSON5 mode
- json5 : JSON5.parse only
- auto : try JSON, fall back to JSON5 (existing behaviour and default
when the flag is undefined, so older hosts keep working)
URL/MIME hints for .json5 sources are still respected. README updated
with the modes table and a Vite wiring example.
