## Code sample

### Node.js


To authenticate to Cloud SQL for SQL Server, set up Application Default Credentials.
For more information, see

[Set up authentication for a local development environment](https://docs.cloud.google.com/docs/authentication/set-up-adc-local-dev-environment.md.txt).

```javascript
// 'connectionTimeout` is the maximum number of milliseconds to wait trying to establish an
// initial connection. After the specified amount of time, an exception will be thrown.
config.connectionTimeout = 30000;
// 'acquireTimeoutMillis' is the number of milliseconds before a timeout occurs when acquiring a
// connection from the pool.
config.pool.acquireTimeoutMillis = 30000;
// 'idleTimeoutMillis' is the number of milliseconds a connection must sit idle in the pool
// and not be checked out before it is automatically closed
(config.pool.idleTimeoutMillis = 600000),
```
