Encore Service Structure

Instructions

Creating a Service

Every Encore service needs an encore.service.ts file:

typescript

// encore.service.ts
import { Service } from "encore.dev/service";

export default new Service("my-service");

Minimal Service Structure

my-service/
├── encore.service.ts    # Service definition (required)
├── api.ts               # API endpoints
└── db.ts                # Database (if needed)

Application Patterns

Single Service

A service can be defined at the application root:

my-app/
├── package.json
├── encore.app
├── encore.service.ts
├── api.ts
├── db.ts
└── migrations/
    └── 001_initial.up.sql

Multi-Service

Each service lives in its own directory:

my-app/
├── encore.app
├── package.json
├── user/
│   ├── encore.service.ts
│   ├── api.ts
│   └── db.ts
├── order/
│   ├── encore.service.ts
│   ├── api.ts
│   └── db.ts
└── notification/
    ├── encore.service.ts
    └── api.ts

Large Application (System-based)

Group related services into systems:

my-app/
├── encore.app
├── commerce/
│   ├── order/
│   │   └── encore.service.ts
│   ├── cart/
│   │   └── encore.service.ts
│   └── payment/
│       └── encore.service.ts
├── identity/
│   ├── user/
│   │   └── encore.service.ts
│   └── auth/
│       └── encore.service.ts
└── comms/
    ├── email/
    │   └── encore.service.ts
    └── push/
        └── encore.service.ts

Service-to-Service Calls

Import other services from ~encore/clients:

typescript

import { user } from "~encore/clients";

export const getOrderWithUser = api(
  { method: "GET", path: "/orders/:id", expose: true },
  async ({ id }): Promise<OrderWithUser> => {
    const order = await getOrder(id);
    const orderUser = await user.get({ id: order.userId });
    return { ...order, user: orderUser };
  }
);

Guidelines

Services cannot be nested within other services
Use ~encore/clients for cross-service calls (never direct imports)
Each service can have its own database
Service names should be lowercase, descriptive
Don't create services just for code organization - use folders instead
Use encore-architecture when the service boundaries have not been decided

encore-api

Define typed API endpoints in Encore.ts using api(...) from encore.dev/api. Covers typed request/response interfaces, path/query/header/cookie params, request validation, and APIError. For raw endpoints (api.raw()) and inbound webhooks, use encore-webhook instead.

encore-architecture

Design or revise the service architecture of an Encore.go or Encore.ts application. Covers service boundaries, data ownership, synchronous calls versus Pub/Sub, process allocation, public and private interfaces, and evolving a monolith.
