Root cause of 'Method does not exist / The methods of the module is undefined':
Cocos 3.8 expects handlers inside a 'methods' export (plus load/unload hooks),
not flat on module.exports. Handlers receive args directly (no event); return
value is the request reply. Verified vs official 3.8 first/messages docs.
Also: menu path + panel title switched to literal strings (i18n showed 'undefined').
Task 12 of plan 2026-06-20-config-editor-foundation. Adds:
- src/main/index.ts: onLoad + message handlers (return value = request resolve,
per Cocos 3.x verified IPC mechanism; fallback note left in plan)
- src/panels/default/{index,app}.ts: Editor.Panel.define host + Vue 3 minimal
app (table switcher, key list, record JSON dump)
- static/template/default/index.html + static/style/default/index.css
Deviation from plan (necessary, flagged): esbuild.config.mjs now marks
node:fs/node:path as external for the panel entry (platform:'browser').
The plan's panel reads static template/style at runtime via Node fs, which
requires these builtins; Cocos panel runs in an Electron renderer that
provides them. Without this, esbuild errors with 'Could not resolve node:fs'.
Build verified: dist/main.js (9.5mb, typescript compiler API bundled) and
dist/panels/default.js (628kb, vue.esm-bundler bundled) both generate.
Task 11 of plan 2026-06-20-config-editor-foundation. Holds three TsConfigFile
instances (hero/skill/field), implements query*/validate/saveRecord/revertRecord
message handlers. saveRecord validates before persisting, rolls back on error,
and refreshes asset-db on success. HeroList read via regex.
