A simple connection pool for tedious.

Status: Experimental


The only difference from the regular tedious API is how the connection is obtained. Once a Connection object has been acquired, the tedious API can be used with the connection as normal.

var ConnectionPool = require('tedious-connection-pool');

var pool = new ConnectionPool(poolConfig, connectionConfig);

pool.requestConnection(function (err, connection) {
  if(!err) {
    var request = new Request('select 42', function(err, rowCount) {
      assert.strictEqual(rowCount, 1);

      // Release the connection back to the pool.

    request.on('row', function(columns) {
      assert.strictEqual(columns[0].value, 42);

    connection.on('connect', function(err) {

When the connection is closed it is returned to the pool. It is then available to be reused.
