func NewSinglePageAppHandler ¶

func NewSinglePageAppHandler(embedFs fs.FS, embedPath string) (http.Handler, error)

NewSinglePageAppHandler returns an HTTP handler for serving a single-page application.

In regular builds, the handler serves files from the provided embedFs, which generally should be an embed.FS. In debug builds (activated via the -tags debug flag), it attempts to locate and serve static assets from the file system using the provided embedPath.

Parameters:

• embedFs: an fs.FS providing the embedded static assets.
• embedPath: a relative file path to the static assets, used only in debug mode.

Returns:

• http.Handler: a handler that serves static files if they exist, or falls back to serving the root file (typically index.html) when a file is not found.
• error: an error value if the handler cannot be instantiated in debug mode; nil otherwise.
