Introduces showcase/shell/src/lib/runtime-config.ts (server-only —
imports next/cache and is read at request time by the root layout)
plus runtime-config.client.ts (reads window.__SHOWCASE_CONFIG__
injected by the layout). Shell's RuntimeConfig contains baseUrl and
posthogHost. getRuntimeConfigEdge() provides the Edge-runtime variant
for middleware (skips unstable_noStore).
Adds vitest config + dev deps to package.json and red-green tests for
both modules. Tests verify env-vs-fallback precedence, trailing-slash
stripping, no-module-load-freeze (live process.env reads per call),
and the Edge wrapper's noStore-skip behavior.
Refs plan-B §B7.
The "next" dist-tag was a workaround for Docker builds that can't resolve
workspace:* — but "next" has gone stale (1.55.2-next.1) while "latest" is
at 1.56.5. Renovate doesn't cover showcase/, so these never auto-bumped.
Switch all 19 showcase package.json files to "latest".
Now that generated JSON is gitignored, every path that consumes these
files must run generators first. Fixes:
- shell: add bundle-demo-content to dev preamble (eliminates race
between watcher and Next.js on fresh clone); add
bundle-starter-content to Dockerfile RUN chain
- shell-dojo: add predev hook (generate-registry + bundle-demo-content)
- shell-docs: add predev hook (generate-registry + bundle-demo-content
+ generate-search-index)
- ops: replace direct COPY of gitignored registry.json with
generate-registry.ts at build time (copy scripts+shared+packages,
npm ci, run generator)
Next.js 15.4.10's turbopack panics ("Next.js package not found") on the
repo's multi-lockfile layout. Webpack dev works; production builds are
unaffected.
