Neon · Method

pool.connect

Use Neon's pooled endpoint and keep each container's local pool small. Create the pool globally so warm serverless invocations can reuse it without causing connection exhaustion.

Syntax

const pool = new Pool({ connectionString, max: 1|2, idleTimeoutMillis: 5000 });
const client = await pool.connect();
client.release();
