spectral derivative of aperiodic function

I would like to calculate the spatial derivative of a variable defined on the points of a uniform grid. The domain is NOT periodic, so the FFT method is useless here. I wonder if there exist other spectral methods to calculate the derivative on an aperiodic domain or if my only hope is to use the finite difference method?
