  The production of $W$ and $Z$ bosons in association with jets is studied in
the forward region of proton-proton collisions collected at a centre-of-mass
energy of 8 TeV by the LHCb experiment, corresponding to an integrated
luminosity of 1.98 $\pm$ 0.02 fb$^{-1}$. The $W$ boson is identified using its
decay to a muon and a neutrino, while the $Z$ boson is identified through its
decay to a muon pair. Total cross-sections are measured and combined into
charge ratios, asymmetries, and ratios of $W+$jet and $Z$+jet production
cross-sections. Differential measurements are also performed as a function of
both boson and jet kinematic variables. All results are in agreement with
Standard Model predictions.
