SHOC Frontend (shoc-frontend-new)

Vite + React SPA for Sea Haven facility management (SHOC): work orders, vendor portal, uplifts, and related admin features. This is the selective rebuild of the legacy SHOC frontend — new code follows the IrisLoan.Admin conventions documented in docs/ARCHITECTURE_PLAN.md.

• GitHub: Sea-Haven-Industries/shoc-frontend-new
• Hosted at: https://dev.seahaven.com (dev environment; the only environment today)
• Backend API: https://api.dev.seahaven.com/api (called directly, cross-origin) — source: Sea-Haven-Industries/shoc-backend

Architecture

Static SPA hosting on AWS, owned by HCP Terraform (terraform/README.md). CloudFront serves the built dist/ from a private S3 bucket using a current/previous origin group; the SPA calls the backend directly over HTTPS at VITE_API_URL (no /api proxy at the CDN — the backend allows CORS).

Dev hosting and content CD are owned by HCP Terraform (SH-300). Staging still uses CloudFormation outputs and scripts/deploy-web.sh (SH-287).

Frontend stack: React 19, TypeScript, Vite, Tailwind CSS 4 + MUI, TanStack Query, React Router (via @generouted/react-router), React Hook Form + Zod, Ky HTTP client. Source layout: src/api/, src/domain/, src/app/ (see the architecture plan for the keep/discard migration matrix).

AWS Resources

HCP workspace shoc-frontend-new-dev — account 396287094661, region us-east-1. Defined in terraform/live/dev.

Resource	Name	Purpose
S3 bucket	seahaven-shoc-frontend-dev	Private origin (BLOCK_ALL, SSE, versioned; OAC-only reads)
CloudFront distribution	(stack output DistributionId)	HTTPS static hosting on dev.seahaven.com, ACM *.seahaven.com
CloudFront Function	SpaRewrite	Viewer-request rewrite of extensionless paths to /index.html (deep links)
IAM role	githubdeploy-shoc-frontend-new-dev	GitHub Actions OIDC deploy role, trust scoped to repo:Sea-Haven-Industries/shoc-frontend-new:ref:refs/heads/dev
Route 53 records	A/AAAA apex alias in zone dev.seahaven.com (Z07671212N75U4YLPWZR8)	Points the custom domain at CloudFront

No Lambdas, queues, or databases — this stack is static hosting only.

Configuration

Secrets

No Secrets Manager or SSM parameters. AWS access is OIDC only; the deploy role ARNs are deterministic and pinned in the workflows. The one GitHub Actions repo secret is:

Secret	Purpose
SENTRY_AUTH_TOKEN	Source-map upload by scripts/upload-sourcemaps.sh after a deploy

Environment variables (build-time, VITE_*)

Variable	Description	Dev value
VITE_API_URL	Ky API base prefix, baked into the build at vite build	/api (dev server) / https://api.dev.seahaven.com/api (production build)
VITE_API_TARGET	Dev-proxy target for /api (Vite dev server only)	http://localhost:5141

VITE_API_URL supplies the full API prefix — route paths in API_PATHS do not include /api. Absolute values must end with /api; vite.config.ts enforces this via config/api-url-contract.ts and fails the build otherwise. See .env.example, .env.development, and .env.production.

Pinned hosting constants (domain, certificate ARN, hosted zone) live in terraform/live/dev/main.tf.

Local Development

Requirements: Node.js ≥ 22.22.1 (CI/CD run Node 24), npm 11.16.0 (pinned via packageManager).

npm ci
cp .env.example .env   # then set VITE_API_URL=/api for local dev
npm run dev            # Vite dev server on port 3000, proxies /api → VITE_API_TARGET

The dev proxy expects the shoc-backend API at http://localhost:5141; override with VITE_API_TARGET (e.g. https://api.dev.seahaven.com to use the deployed dev API).

Command	Description
npm run dev	Start Vite dev server on port 3000
npm run build	Type-check (tsc -b) and production build to dist/
npm run preview	Preview the production build locally
npm test / npm run test:watch	Vitest unit tests (once / watch)
npm run test:e2e / npm run test:e2e:ui	Playwright e2e tests (headless / UI mode)
npm run lint / npm run lint:fix	ESLint (check / auto-fix)
npm run format / npm run format:check	Prettier (write / check)
npm run governance	Governance checks (godfile, maintainability, Terraform, CD guards)
npm run verify	All gates: format + lint + build + test + governance

npm run governance needs terraform and python3 on PATH for the Terraform and content-CD gates.

Husky + lint-staged run ESLint and Prettier on staged files at commit; commitlint enforces conventional commit messages. Run npx tsc --noEmit (or npm run build) before pushing to catch type errors early.

Contributing

• Branch from dev with a kebab-case description and a prefix matching the work: feature/, bug/, hotfix/, chore/, docs/, or refactor/ (e.g. feature/vendor-portal-filters, chore/sea-haven-branding).
• Commit messages follow Conventional Commits — commitlint rejects anything else at commit time.
• Open PRs against dev. Both dev and main are protected: every PR needs a green CI run and an approving review from a code owner (@Sea-Haven-Industries/internal-dev); new pushes dismiss stale approvals. Merged branches are deleted automatically.
• A PR that changes terraform/** may not also change application code (the terraform-isolation CI job); ship Terraform in its own PR.
• Promotion flow: feature/* → dev (deployed to dev.seahaven.com through Terraform content CD once TERRAFORM_CONTENT_CD_ENABLED=true) → main (production promotion — no prod environment exists yet).

Deployment

No stored AWS keys — OIDC only. Infrastructure and content deploy separately:

• CI (.github/workflows/ci.yaml) — on push and PRs to main/dev/staging, calls Sea-Haven-Industries/.github → ci-typescript-frontend.yaml (Node 24): format check, lint, build, tests; and runs a repo-owned governance job that calls npm run verify so every gate (including the maintainability ratchets in scripts/governance-check.mjs, the Terraform gates, and the content-CD guards) is guaranteed from this repository. Conventions and gates are documented under AGENTS.md, QUALITY_GATES.md, ARCHITECTURE_AND_CODE_QUALITY.md, and REVIEW_AND_PR_FRAMEWORK.md.
• Terraform isolation (.github/workflows/terraform-isolation.yaml) — fails a PR that mixes terraform/** with application code, so a Terraform merge never races a content release for the HCP workspace.
• Dev content (.github/workflows/deploy.yml) — workflow_dispatch on dev, and push-to-dev when vars.TERRAFORM_CONTENT_CD_ENABLED is true (paths-ignore: terraform/**). GitHub uploads releases/<sha>-<run>-<attempt>/ only. Terraform updates .release/current, both origin paths, and the invalidation action. Verify and rollback share scripts/verify-cloudfront-release.sh. Every run prints a live-state summary.
• Staging content (.github/workflows/deploy-staging.yml) — on push to staging, unchanged.
• Infrastructure — administrator-run HCP Terraform workspace shoc-frontend-new-dev (terraform/README.md). Staging hosting stays on the existing CloudFormation stack until SH-287.

Do not run scripts/deploy-web.sh against dev. That script remains the staging content publisher only.

Operations

• Verify: open https://dev.seahaven.com after a green Deploy dev content run in the Actions tab; confirm a deep link (e.g. a work-orders route) loads directly and API calls succeed.
• Logs: deploy logs live in GitHub Actions (CI + Deploy workflows). There are no CloudWatch application logs — the stack is static hosting; runtime errors surface in the browser and on the backend API's side.
• Common failure modes:
  • Stale content after deploy — CloudFront is still InProgress or an edge still serves the previous index.html hash. Read the live-state summary before assuming the site is down.
  • OIDC AssumeRole errors — the trust policy is scoped to the dev ref on this repo; dispatching the workflow from another branch is rejected by design.
  • Broken API requests after a build — VITE_API_URL missing the /api suffix or carrying the wrong environment's host (it is baked in at build time).
  • CORS errors — the backend must allow the frontend origin; CloudFront does not proxy /api.
• Push-to-dev is gated. Merging to dev publishes only when TERRAFORM_CONTENT_CD_ENABLED=true. Merging a terraform/** change queues an HCP Terraform run that a human confirms or discards before the next content release (see the operational rules in terraform/README.md).
