JavaScript: Insert data

• By default, every time you run insert(), the client library will make a select to return the full record. This is convenient, but it can also cause problems if your Policies are not configured to allow the select operation. If you are using Row Level Security and you are encountering problems, try setting the returning param to minimal.

Examples

Create a record

const { data, error } = await supabase
  .from('cities')
  .insert([
    { name: 'The Shire', country_id: 554 }
  ])

Bulk create

const { data, error } = await supabase
  .from('cities')
  .insert([
    { name: 'The Shire', country_id: 554 },
    { name: 'Rohan', country_id: 555 },
  ])

Upsert

const { data, error } = await supabase
  .from('cities')
  .insert(
    [
      { name: 'The Shire', country_id: 554 },
      { name: 'Rohan', country_id: 555 },
      { name: 'City by the Bay', country_id:840}
    ],
    { upsert: true })
