Error:createClient is not defined When using supabase cdn

I'm using Supabase CDN's for a project. When I call the createClient() function this error comes up:

createClient is not defined

I tried it with an older version of the CDN, with another browser and using the old method of SupabaseClient.createClient, but I got:

SupabaseClient is not defined

Is the CDN not working correctly or something else?

const SupabaseKey = // api here
const SupabaseUrl =// URL here

const options = {
  db: {
    schema: 'public',
  },
  auth: {
    autoRefreshToken: true,
    persistSession: true,
    detectSessionInUrl: true
  }
}

const supabase = createClient(SupabaseUrl, SupabaseKey, options)

Solution

I fixed it by adding an import statement in the JS file like this:

import createClient from 'https://cdn.jsdelivr.net/npm/@supabase/supabase-js/+esm'

The +esm at the end of the URL is from universal module and it now works.
