-### Using pretranspiled version of BootstrapVue for Nuxt.js

-Nuxt.js module uses the precompiled version of BootstrapVue (`es/`) for faster development builds
-and the source (`src/`) of BootstrapVue for higher quality production builds.

-You can override this option using `usePretranspiled` option. Setting to `true` uses `es/` instead

-    <code>false</code> if importing from <code>bootstrap-vue/src</code>). Otherwise, you may end
