Creating a Supabase Client

We will be creating a client to interact with Supabase using the supabase-js library.

Install the supabase-js library
```
npm install @supabase/supabase-js
```

Create a new file called utils/supabase.ts and add the following:

// utils/supabase.ts

import { createClient } from '@supabase/supabase-js'

let supabase_url = process.env.NEXT_PUBLIC_SUPABASE_URL || "TODO: Your Supabase URL"
let supabase_key = process.env.NEXT_PUBLIC_SUPABASE_KEY || "TODO: Your Supabase Key"

const getSupabase = (access_token: string) => {
  const supabase = createClient(
    supabase_url,
    supabase_key
  )

  supabase.auth.session = () => ({
    access_token,
    token_type: "",
    user: null
  })

  return supabase
}

export { getSupabase }
