Example backends

Four small backends on authbase, with the same routes so one script (smoke.sh) tests them all; CI runs every one against the compose stack.

	Stack	Port	Uses
express	Node, Express 5	3001	@authbase/node
ktor	Kotlin, Ktor 3	3002	authbase-ktor
spring	Kotlin, Spring Boot 4	3003	authbase-spring-boot-starter
go	Go, net/http	3004	no SDK: lestrrat-go/jwx, as in the integration guide

Route
POST /signup {email, password}	creates the user in authbase and logs in → 201 {user_id, access_token, refresh_token}
POST /login {email, password}	→ {access_token, refresh_token}
POST /refresh {refresh_token}	→ a new pair; the old refresh token is dead
POST /logout {refresh_token}	→ 204
GET /me	Bearer token → {id, email, roles}; verified locally
GET /admin	needs the admin role → 403 without it

Run one

Start authbase and get an API key (quick start), then, with the key only in your environment:

export AUTHBASE_URL=http://localhost:8080 AUTHBASE_API_KEY=sk_live_…

# Express: the SDK is used from source, so build it first
(cd sdk/typescript && npm ci && npm run build) && cd examples/express && npm install && npm start
# Go
cd examples/go && go run .
# Ktor / Spring Boot: Gradle builds the Kotlin SDK from source (includeBuild)
cd examples/ktor && ./gradlew run
cd examples/spring && ./gradlew bootRun

# in another shell
examples/smoke.sh http://localhost:3001
