We present a theory of one-neutron halo breakup reactions within the framework of post-form distorted wave Born approximation wherein pure Coulomb, pure nuclear, and their interference terms are treated consistently in a single setup. This formalism is used to study the breakup of one-neutron halo nucleus ${}^{11}\mathrm{Be}$ on several targets of different masses. We investigate the role played by the pure Coulomb, pure nuclear, and the Coulomb-nuclear interference terms by calculating several reaction observables. The Coulomb-nuclear interference terms are found to be important for more exclusive observables.
