Start building

Use the Supabase client to interact with your database, authenticate users, store files, and more.
// Query your database
const { data, error } = await supabase
  .from('todos')
  .select('*')
  .order('created_at', { ascending: false })

// Listen to realtime changes
supabase
  .channel('todos')
  .on('postgres_changes', { event: '*', schema: 'public', table: 'todos' }, 
    (payload) => console.log('Change received!', payload)
  )
  .subscribe()
