Supabase PostgreSQL

Every Supabase project is a dedicated PostgreSQL database, trusted by millions of developers. PostgreSQL is a powerful open-source relational database management system (RDBMS), renowned for stability, scalability, and robustness. It is an ideal choice for applications that require data consistency and reliability.

Prerequisites

• Get PostgreSQL database connection parameters from the database owner.

• Refer to IP allowlist to add IP addresses of Lowcoder to your allowlist (if needed).

All of the above functionalities can be accessed using Supabase SDK as well.

To fetch data from DB, we can use the Select method on Supabase object.

const { data, error } = await supabase
  .from('countries')
  .select()

To insert data into a Table, use following code.

const { error } = await supabase
  .from('countries')
  .insert({ id: 1, name: 'Denmark' })
