node js return ID in postgres insert

To return the ID in a PostgreSQL insert using Node.js, you can follow these steps:

1. Establish a connection to the PostgreSQL database using a library like pg-promise or node-postgres.

2. Create an SQL query that includes an INSERT statement to insert data into the table and a RETURNING clause to retrieve the inserted ID. The RETURNING clause allows you to specify which columns you want to retrieve from the inserted row. For example:

const query = `INSERT INTO table_name (column1, column2) 
               VALUES ($1, $2) 
               RETURNING id`;

1. Use the query method of the database connection to execute the SQL query. Pass the necessary parameters as an array to prevent SQL injection attacks. For example:

const values = [value1, value2];
const result = await db.query(query, values);

1. Retrieve the inserted ID from the result. The ID will be available in the rows property of the result object. For example:

const insertedId = result.rows[0].id;

1. Use the retrieved ID as needed in your application logic.

Remember to handle any errors that may occur during the database connection or query execution process.
