A walkthrough of moving a Next.js (output: 'export') site from Vercel to GitHub Pages and turning the Vercel deployment into a redirect-only surface via vercel.json. Documents five or six attempts that failed for non-obvious reasons (framework detection, output validation, path-to-regexp quirks around trailing slashes) and the final config that actually works.
Notes on a Next.js 16 + next-intl app where useRouter().push() silently becomes a no-op only in production builds, breaking interactivity on a search page, and a history.pushState + popstate workaround that restores it.
A record of porting kuzushiji/historical-document character detection (YOLOv11) and NDL's koten-OCR-Lite (RTMDet + PARSeq) to JS/Next.js with onnxruntime-node — no Python. Covers ONNX export, SAHI, line detection, an int8 quantization accuracy comparison, why it is hard to run on Vercel, and extracting the core into a shared library.
Notes from migrating tech.ldas.jp from Hugo to Next.js (Cloudflare Workers + OpenNext) and adding a Stripe-backed membership with members-only post gating. Covers Workers Free plan CPU limits, Stripe SDK on Workers, SSG/dynamic interplay, and Japan-specific business onboarding details — the parts that the official docs don't quite spell out for this combination.
Serving IIIF historic maps as a WMTS-compatible tile service, built on top of Allmaps and integrated into a Next.js portfolio site.
Notes on extending an admin console so that adding sites and actions requires editing one YAML file rather than touching code, with a tabbed UI for multiple actions per site.
Notes on building an admin console where non-engineers can trigger deploys and data updates for multiple database sites without GitHub or Vercel accounts. Combines GitHub App authentication with Cloudflare Access (Zero Trust), and walks through how PAT, OAuth App, and GitHub App differ.
An implementation log for a digital archive that delivers historical photographs which cannot be made fully public, while still preserving the benefits of IIIF (spec-compliant high-resolution viewer, manifest delivery) for an authorized membership. The stack is Cantaloupe (IIIF server) + S3-compatible storage + Elasticsearch (search) + Next.js (UI) + Cloudflare Tunnel + Access. We also lay out where IIIF Auth API 2.0 would fit in for cross-host interoperability.
Immediately after migrating a Nuxt 2 + @nuxtjs/pwa SPA to a different framework, some users kept seeing frozen, outdated HTML. The cause was the old Service Worker's cache-first strategy. This post documents the procedure for retiring it by serving a kill-switch SW at the same URL.
A record of migrating organization-facing Next.js apps from Vercel Pro to Cloudflare Pages, enabling a downgrade to the free Vercel Hobby plan.
A step-by-step record of migrating a Next.js API server from AWS Amplify (with WAF) to Cloudflare Pages, reducing monthly costs from roughly $23 to $0.
Notes on adding Meta Quest support to a Next.js + React Three Fiber 3D viewer using @react-three/xr v6. Covers the CameraRig XR-camera hijacking issue, the callback vs. ref pitfall in useXRControllerLocomotion, Quest device debugging techniques, and more.
How to use ExcelJS data validation to generate Excel templates with dropdowns that reference data in other sheets, served from a Next.js API route.
