Elysia API Documentation

Overview

This project uses ElysiaJS integrated with Next.js App Router to create high-performance, type-safe APIs. The codebase follows a Feature-based MVC pattern for maintainability and scalability.

File Responsibilities

Model (`model.ts`)

Define TypeBox schemas for validation
Export TypeScript types from schemas
All data structure definitions

Service (`service.ts`)

Business logic and data operations
Pure functions (no Elysia dependencies)
CRUD operations
Data transformation

Controller (`controller.ts`)

Elysia instance for the module
Route definitions and handlers
Request/response validation
Calls service functions
HTTP-specific concerns

Main Route (`app/api/[[...slugs]]/route.ts`)

Import all controllers
Combine with .use()
Export handlers for Next.js

Important Implementation Notes

This project follows the correct ElysiaJS + Next.js integration pattern:

✅ Single route file [[...slugs]]/route.ts with Elysia internal routing
✅ Uses export const GET = app.fetch (not .handle)
✅ Elysia instance has prefix: '/api'
✅ All routes defined within Elysia instances using .get(), .post(), etc.
✅ WinterCG compliant - works as normal Next.js API route
✅ Feature-based MVC pattern for maintainability
✅ Clear separation of concerns between Model, View, and Controller
✅ Branch-level data scoping for multi-tenant architecture
✅ Audit logging for all operations
✅ Soft delete with deletedAt field
✅ Multi-language support (Thai/English)

Technologies Used

ElysiaJS: Type-safe, high-performance web framework
Next.js 16: React framework with App Router
TypeScript: Type safety throughout
TypeBox: Schema validation (via @elysiajs/schema)
Drizzle ORM: Type-safe SQL ORM
PostgreSQL: Primary database

Features

✅ Feature-based MVC architecture ✅ Dynamic branch parameter support ✅ Type-safe request/response validation ✅ Optional query parameter filtering ✅ Mock data for customers and quotations ✅ Full TypeScript support ✅ Auto-generated API documentation (Swagger/OpenAPI ready) ✅ Correct ElysiaJS + Next.js integration pattern ✅ Scalable and maintainable code structure ✅ Clear separation of concerns ✅ Multi-tenant architecture with branch scoping ✅ Complete audit logging system ✅ Soft delete for data integrity ✅ Multi-language support (Thai/English) ✅ Hierarchical data structures (locations) ✅ GPS coordinate support (industrial estates) ✅ Admin-only access control (audit logs)

Adding New Modules

To add a new module (e.g., products):

Create folder: src/modules/products/
Create model.ts - Define schemas
Create service.ts - Business logic
Create controller.ts - Routes and handlers
Create index.ts - Module exports

Update src/app/api/[[...slugs]]/route.ts:

import { products } from "@/modules/products/controller";

const app = new Elysia({ prefix: "/api" })
  .use(customers)
  .use(quotations)
  .use(masterOptions)
  .use(locations)
  .use(industrialEstates)
  .use(auditLogs)
  .use(products); // Add new module

Security & Access Control

Branch Middleware

All routes use branchMiddleware which injects:

currentBranchId - Current user's branch
userId - Current user ID
userGroups - User groups/roles
accessibleBranches - Branches user can access

Permission Levels

Standard Users: Access to branch-scoped data
Admin/Superadmin: Full access + audit logs
Auditor: Read-only access to audit logs

Data Isolation

All queries are automatically filtered by branchId
Cross-branch access is prevented
Soft delete ensures data integrity
