app.go:793–797

NewWithCustomCtx creates a new Fiber instance and applies the provided function to generate a custom context type. It mirrors the behavior of calling `New()` followed by `app.setCtxFunc(fn)`.

(newCtxFunc func(app *App) CustomCtx, config ...Config)

// provided function to generate a custom context type. It mirrors the behavior
// of calling `New()` followed by `app.setCtxFunc(fn)`.
func NewWithCustomCtx(newCtxFunc func(app *App) CustomCtx, config ...Config) *App {
	app := New(config...)
	app.setCtxFunc(newCtxFunc)
	return app
}

// GetString returns s unchanged when Immutable is off or s is read-only (rodata).
// Otherwise, it returns a detached copy (strings.Clone).
