Not all ox_lib functions found in Lua are supported, the ones that are will have a JS/TS example on the documentation.
You still need to use and have the ox_lib resource included into the resource you are using the npm package in.
# With pnpm
pnpm add @communityox/ox_lib
# With Yarn
yarn add @communityox/ox_lib
# With npm
npm install @communityox/ox_lib
You can either import the lib from client or server files or deconstruct the object and import only certain functions you may require.
import lib from '@communityox/ox_lib/client'
import lib from '@communityox/ox_lib/server'
import { checkDependency } from '@communityox/ox_lib/shared';
