Overview

Package api contains the HTTP endpoints of the Karman API. We use the github.com/go-chi/chi router. Every collection of endpoints is implemented as a Handler type that exposes a Router function compatible with Chi's Route function. Many handlers contain sub-handlers from their respective sub-packages.

Package api also contains some utility packages that are used across API endpoints. These include consistent error messages and middlewares used across the API.

Types

type Handler

type Handler struct {
	// contains filtered or unexported fields
}

Handler is the main API handler. This is basically the root entrypoint of the Karman API. All other API endpoints are created as sub-handlers of this controller.

func NewHandler

func NewHandler(logger *slog.Logger, hc HealthChecker, songRepo song.Repository, songSvc song.Service, mediaSvc media.Service, mediaStore media.Store, uploadRepo upload.Repository, uploadStore upload.Store, debug bool) *Handler

NewHandler creates a new Handler instance using the specified dependencies. The injected dependencies are passed along to the sub-handlers. debug indicates whether additional debugging features should be enabled.

func (*Handler) Healthz

func (h *Handler) Healthz(w http.ResponseWriter, r *http.Request)

Healthz implements the /healthz endpoint.

func (*Handler) MethodNotAllowed

func (*Handler) MethodNotAllowed(w http.ResponseWriter, r *http.Request)

MethodNotAllowed is an HTTP endpoint that renders a generic 405 Method Not Allowed error. This endpoint is the default 405 endpoint for the Handler and its sub-handlers.

func (*Handler) NotAcceptable

func (*Handler) NotAcceptable(w http.ResponseWriter, r *http.Request)

NotAcceptable is an HTTP endpoint that renders a generic 406 Not Acceptable error. This endpoint is the default 406 endpoint fo the Handler and its sub-handlers.

func (*Handler) NotFound

func (*Handler) NotFound(w http.ResponseWriter, r *http.Request)

NotFound is an HTTP endpoint that renders a generic 404 Not Found error. This endpoint is the default 404 endpoint for the Handler and its sub-handlers.

func (*Handler) ServeHTTP

func (h *Handler) ServeHTTP(w http.ResponseWriter, r *http.Request)

ServeHTTP processes HTTP requests for h.

type HealthCheckFunc

type HealthCheckFunc func(ctx context.Context) bool

HealthCheckFunc is a convenience wrapper around HealthChecker.

func (HealthCheckFunc) HealthCheck

func (f HealthCheckFunc) HealthCheck(ctx context.Context) bool

HealthCheck invokes f.

type HealthChecker

type HealthChecker interface {
	// HealthCheck performs a health check and returns its result.
	// A result of true indicates that the system is healthy.
	HealthCheck(ctx context.Context) bool
}

HealthChecker is an interface that can provide information about the system health.
