The first auto-deploy from PR #3855 returned HTTP 500 on every page
with the runtime error `TypeError: components.ComponentMod.handler is
not a function`. Captured via `wrangler tail`.
Root cause: Next.js 16.2.6 was published 2026-05-07 19:01 UTC, *after*
@opennextjs/cloudflare 1.19.8 was published earlier the same day at
11:33 UTC. OpenNext 1.19.8's peerDependency declares
`next: '>=15.5.16 <16 || >=16.2.5'` — 16.2.6 falls inside the range
syntactically, but the route component module export shape changed in
that patch and OpenNext has not caught up yet.
Pin Next + eslint-config-next to 15.5.18 (latest 15.x LTS, the other
half of OpenNext's supported range). Revert the migration-only changes
that came with the 16 bump:
- eslint.config.mjs: `nextPlugin.configs["core-web-vitals"]` (v16
shape) -> `nextPlugin.flatConfig.coreWebVitals` (v15 shape).
- tsconfig.json: `jsx: "react-jsx"` -> `jsx: "preserve"` (Next 15
default).
- tsconfig.json: add `noUncheckedSideEffectImports: false` because
TypeScript 6 enabled this option under `strict` and Next 15's
bundled types do not declare ambient CSS modules (Next 16 does).
All other web/ deps stay at latest. lucide-react remains pinned at
0.577.0 from #3853 for the same brand-icon reason. Re-evaluate Next 16
when @opennextjs/cloudflare ships a release explicitly tested against
\>= 16.2.6.
Side effects from `bun run format` (prettier 3.8) and `bun run build`
(Next 16) that I missed in the prior commit:
- web/components/ui/badge.tsx, web/components/ui/button.tsx: prettier 3.8
inlines short interface `extends` lists onto a single line.
- web/tsconfig.json: Next 16's build step auto-modernizes tsconfig:
`jsx: "preserve"` → `jsx: "react-jsx"` and reformats `lib`/`paths`
arrays to multi-line. Build is identical either way; committing the
modernized shape so subsequent `next build` runs do not produce
spurious diffs.
Imports the public marketing site previously living in
../oh-my-opencode-web. Independent of the npm plugin: own package.json,
bun.lock, tsconfig.json. Not included in the published package — root
files: array still only ships dist/, bin/, postinstall.mjs.
Stack:
- Next.js 15.5 App Router + RSC, deployed to Cloudflare Workers via
@opennextjs/cloudflare (build target .open-next/worker.js).
- Tailwind v4 + shadcn/ui primitives.
- next-intl with 4 locales (en/ja/ko/zh) under app/[locale]/.
- Playwright e2e tests under web/e2e/.
- Custom domains ohmyopenagent.com (primary) and ohmyopencode.org
(legacy alias) declared in web/wrangler.toml.
Source files were re-formatted via `bun run format` to bring them in
line with the existing .prettierrc (singleQuote: false). Functional code
unchanged.
