Resource Pool Management

This code demonstrates how to create a resource pool with minimum and maximum limits, and manage resource acquisition and release. It handles timeouts and resource reaping intervals.

const { Pool } = require('tarn');
const pool = new Pool({
  create: () => Promise.resolve(new Resource()),
  destroy: resource => Promise.resolve(resource.dispose()),
  min: 2,
  max: 10,
  acquireTimeoutMillis: 30000,
  idleTimeoutMillis: 30000,
  reapIntervalMillis: 1000
});

pool.acquire().promise.then(resource => {
  console.log('Resource acquired');
  pool.release(resource);
});
