2. Backend API Implementation

API Client (frontends/nextjs/src/lib/entities/api-client.ts)

Changes: Replaced all placeholder implementations with real fetch calls

Before (placeholder):

export function fetchEntityList(...) {
  // TODO: Implement actual API call
  return { data: [], status: 200 }
}

After (real implementation):

export async function fetchEntityList(...) {
  const response = await fetch(url, { method: 'GET', ... })
  const data = await response.json()
  return { data, status: response.status }
}

Features Added:

• ListQueryParams interface for pagination/filtering/sorting
• buildQueryString() utility
• Proper error handling with status code mapping
• Network error handling
• Support for all HTTP methods (GET, POST, PUT, DELETE)

Architecture Notes

Existing Infrastructure (Leveraged)

The following were already implemented and working:

• ✅ API routes at /api/v1/[...slug]/route.ts
• ✅ Authentication middleware with session management
• ✅ Permission level checks (6-level system)
• ✅ Tenant isolation validation
• ✅ DBAL (Database Abstraction Layer)
• ✅ Package system with JSON components

New Additions

• ✅ Real API client implementation (no more placeholders)
• ✅ Query parameter support (pagination, filtering, sorting)
• ✅ Comprehensive test coverage
• ✅ Detailed documentation

---

Breaking Changes

None. All changes are additive or replace placeholder implementations.

• Existing tests: Still passing (same 4 pre-existing failures)
• API routes: Already existed, no changes
• Database schema: No changes
• Configuration: No changes

---

Performance Impact

API Client

• Before: Synchronous placeholder (instant but fake)
• After: Asynchronous fetch calls (real network requests)
• Impact: Minimal - proper async handling already in place

Test Suite

• Before: 220 tests in ~20 seconds
• After: 249 tests in ~22 seconds (+2 seconds for 29 new tests)
• Impact: Negligible - well within acceptable range

---

Next Steps

Based on ROADMAP.md Phase 2 plan:

Immediate (Week 2-3, Q1 2026)

• Request/response validation with Zod
• Rate limiting implementation
• OpenAPI/Swagger specification

Short-term (Week 4-6, Q1 2026)

• Enhanced CRUD UX (RenderComponent forms)
• Client-side validation
• Advanced list features (search, bulk operations)

Medium-term (Q2 2026)

• God Panel UI
• Package management UI
• Schema editor

---

How to Use

Run Unit Tests

cd frontends/nextjs
npm test

Run E2E Tests

# From root
npm run test:e2e

# Specific test file
npx playwright test e2e/crud/complete-flow.spec.ts
npx playwright test e2e/auth/complete-flow.spec.ts
npx playwright test e2e/package-loading.spec.ts

Use API Client

import {
  fetchEntityList,
  fetchEntity,
  createEntity,
  updateEntity,
  deleteEntity,
} from '@/lib/entities/api-client'

// List with pagination and filtering
const { data, error } = await fetchEntityList('acme', 'forum', 'posts', {
  page: 1,
  limit: 20,
  filter: { published: true },
  sort: '-createdAt',
})

// Create entity
const newPost = await createEntity('acme', 'forum', 'posts', {
  title: 'New Post',
  content: 'Content here',
})

// Update entity
const updated = await updateEntity('acme', 'forum', 'posts', '123', {
  published: true,
})

// Delete entity
await deleteEntity('acme', 'forum', 'posts', '123')
