In `@SparkyFitnessFrontend/eslint.config.js`:
- Around line 29-35: Extend the fetch-path ESLint rule in eslint.config.js to
match member-access calls through window.fetch and globalThis.fetch, including
the corresponding template-literal selector, so root-relative backend requests
are flagged. Add regression cases covering both forms and require the existing
apiCall or per-domain API client instead of hand-rolled fetch calls.
- Around line 8-39: Extract noHardcodedBasePathSelectors from eslint.config.js
into an importable shared JavaScript module, then update
SparkyFitnessFrontend/eslint.config.js lines 8-39 to import and use it. Update
SparkyFitnessFrontend/src/tests/eslint/noHardcodedBasePath.test.ts lines 8-45 to
import the same array and remove its duplicate definition, preserving the
existing rule behavior and test coverage.
In `@SparkyFitnessFrontend/src/tests/eslint/noHardcodedBasePath.test.ts`:
- Around line 4-6: Update the structuredClone polyfill assignment to remove the
explicit any parameter by using a generic type parameter, and cast the
JSON.parse result to that same generic type. Preserve the existing clone
behavior and the globalThis.structuredClone fallback.

bug
Adds three utility functions for handling sub-path deployments: - getBasePath(): returns empty string at root, or trimmed path for sub-path - withBasePath(): prefixes a path with the base path - getRouterBasename(): returns base path or '/' for React Router
- Add getAuthBaseUrl() function that constructs auth API URL with base path - Wire getAuthBaseUrl() into authClient's baseURL configuration - Create auth-client tests with jest.isolateModules pattern - Add jest.config.js with better-auth module mocks for test support - Ensure auth endpoints respect sub-path deployments
Reverts out-of-scope infra changes from the auth-client task (shared jest.config.js, package.json jest-block removal, global src/__mocks__ better-auth stubs, and an accidentally committed docs scratch file). Replaces them with local jest.mock() calls inside auth-client.test.ts, matching the existing pattern used elsewhere in the suite, and restores the plain top-level import for getAuthBaseUrl().
Refactor docker-entrypoint.sh to be sourceable (main guarded behind a BASH_SOURCE check) and add normalize_base_path()/NGINX_TEMPLATE_VARS so docker/test-entrypoint.sh can exercise the substitution logic without starting nginx. nginx.conf's location / block now rewrites the served <base href="/"> to SPARKY_BASE_PATH via sub_filter.
vite build emits <base href="/" /> (self-closing with spaces), not <base href="/">, so nginx's sub_filter never matched and SPARKY_BASE_PATH was silently never applied to served HTML. Fix the sub_filter pattern in docker/nginx.conf and the corresponding assertion in docker/test-entrypoint.sh, and verify end-to-end with a real docker build/run/curl cycle.
…int-disable Replaces the eslint-disable-suppressed direct @/api/api import in the SparkyChatInterface page component with a proper hooks/api layered approach: src/api/Chatbot/sparkyChatService.ts now exports getChatStreamUrl(), re-exported from src/hooks/AI/useSparkyChat.ts, matching the existing page -> hooks -> api convention and respecting the no-restricted-imports architecture boundary.
- normalize_base_path now prepends a leading slash when missing, so a value like 'sparky' becomes '/sparky/' instead of a broken relative base href; add shell test coverage for the new cases. - Extract the router routes into a named const so adding the basename option no longer re-indents the entire route table. - Move the getChatStreamUrl re-export out of the import block and document why the hooks layer re-exports it. - Enumerate the companion sub-path env vars in the SPARKY_BASE_PATH example block so they are discoverable in one place.
…RKY_BASE_PATH Adds a no-restricted-syntax rule with 5 AST selectors flagging bare /-prefixed literals used directly as JSX src=/href= or fetch() args, so a future PR can't silently reintroduce the sub-path bug class found in review. Anything already wrapped in withBasePath()/API_BASE_URL, or React Router's Link, is structurally excluded by AST shape.
Found by the new no-restricted-syntax rule (not part of its own commit,
since it's a real, previously-unknown instance of the sub-path bug
class rather than test/config infrastructure) -- src={`/${p.file_path}`}
bypassed SPARKY_BASE_PATH the same way the Task 6/11-14 fixes did.
…allback for sub-path deployments
….prod.yml Neither var was passed to the frontend/server services' environment blocks, so setting them in docker/.env had no effect via docker compose -- silently reproducing the original unprefixed-auth-routing bug this feature exists to fix, and defaulting the frontend to root behavior regardless of the configured sub-path.
- Extract noHardcodedBasePathSelectors into an importable .cjs module shared by eslint.config.js and its test, instead of duplicating the selector array by hand. - Cover window.fetch(...)/globalThis.fetch(...) member-expression calls, which the bare `callee.name === "fetch"` selector missed. - Drop the `any` in the test's structuredClone polyfill for a typed generic cast.

Description
What problem does this PR solve?
Self-hosters who run multiple services behind one reverse-proxied hostname (e.g.
https://homeserver.example.com/sparky/) currently have no way to deploy SparkyFitness at a sub-path — Vite bakes absolute asset paths, React Router has nobasename, and several code paths hardcode domain-root-absolute URLs, all of which break at a sub-path.How did you implement the solution?
Adds a
SPARKY_BASE_PATHenv var (default/) that's substituted into<base href>at request time via nginxsub_filter, driven bydocker/docker-entrypoint.sh. A single frontend source of truth (src/utils/basePath.ts) reads<base href>at runtime; every base-path-aware consumer (router basename, API base URL, Better Auth client base URL, i18n locale loading, and all hardcoded image/asset/link references) is routed through it.vite.config.tsusesbase: './'so built asset references and VitePWA's manifest/service-worker offline fallback resolve correctly at any sub-path. A new ESLint rule flags future hardcoded absolute-path regressions of this bug class. No backend, database, or migration changes; root deployments (SPARKY_BASE_PATHunset) are unaffected.Linked Issue: Closes #1404
How to Test
pnpm devinSparkyFitnessFrontend/.SPARKY_BASE_PATH=/sparky/on the frontend container (andSPARKY_FITNESS_FRONTEND_URL/BETTER_AUTH_URLper the reverse proxy guide), and put it behind a reverse proxy (e.g. Caddy) that strips the/sparkyprefix.https://<host>/sparky/.SPARKY_BASE_PATHunset) is unaffected.bash docker/test-entrypoint.shfrom repo root for the base-path normalization / nginx substitution / build-artifact regression checks (10 assertions).PR Type
