Topics Covered
Routing
fun Application.module() {
install(ContentNegotiation) { json() }
routing {
route("/api/v1") {
get("/users") { call.respond(userService.findAll()) }
get("/users/{id}") {
val id = call.parameters["id"]?.toLongOrNull()
?: throw BadRequestException("Invalid ID")
call.respond(userService.findById(id) ?: throw NotFoundException())
}
}
}
}JWT Authentication
install(Authentication) {
jwt("auth") {
verifier(JWT.require(Algorithm.HMAC256(secret)).build())
validate { credential ->
if (credential.payload.getClaim("userId").asString().isNotEmpty())
UserPrincipal(credential.payload)
else null
}
}
}
authenticate("auth") { userRoutes() }Testing
@Test
fun `GET users returns list`() = testApplication {
application { module() }
client.get("/api/v1/users").apply {
assertThat(status).isEqualTo(HttpStatusCode.OK)
}
}Troubleshooting
| Issue | Resolution |

}Kotlin Ktor Patterns
Design Patterns
Pattern 1: Input Validation
Always validate input before processing:
def validate_input(data):
if data is None:
raise ValueError("Data cannot be None")
if not isinstance(data, dict):
raise TypeError("Data must be a dictionary")
return TruePattern 2: Error Handling
Use consistent error handling:
try:
result = risky_operation()
except SpecificError as e:
logger.error(f"Operation failed: {e}")
handle_error(e)
except Exception as e:
logger.exception("Unexpected error")
raisePattern 3: Configuration Loading
Load and validate configuration:
import yaml
def load_config(config_path):
with open(config_path) as f:
config = yaml.safe_load(f)
validate_config(config)
return configAnti-Patterns to Avoid
❌ Don't: Swallow Exceptions
# BAD
try:
do_something()
except:
pass✅ Do: Handle Explicitly
# GOOD
try:
do_something()
except SpecificError as e:
logger.warning(f"Expected error: {e}")
return default_valueCategory-Specific Patterns: General
Recommended Approach
1. Start with the simplest implementation 2. Add complexity only when needed 3. Test each addition 4. Document decisions
