Functions

func NewHandler

func NewHandler(logger logging.Logger, staticDir string) http.Handler

NewHandler returns an http.Handler that serves static files from staticDir.

A path that resolves to a file on disk is served directly, with a Cache-Control header chosen from its name (see [cacheControl]). A path that does not resolve to a file follows the SPA routing contract: a browser navigation receives index.html so the client-side router can handle the route, while a request for a missing asset (a path with a file extension, or a non-HTML client) receives 404 — so a misconfigured deploy fails loudly at the first request instead of returning index.html as JavaScript ("Unexpected token '<'").
