# Budibase Core backend library This library contains core functionality, like auth and security features which are shared between backend services. #### Note about top level JS files For the purposes of being able to do say `require("@budibase/backend-core/permissions")` we need to specify the exports at the top-level of the module. For these files they should be limited to a single `require` of the file that should be exported and then a single `module.exports = ...` to export the file in commonJS.
