0.5.0: CSV Export

This release upgrades dependencies and runtime environment.

The driver now supports TypeScript's automatic resource management with await using:

await using driver = new ExasolDriver(websocketFactory, config);
await driver.connect();
// The driver is closed automatically when this scope exits.

The release also adds Node.js local CSV export with table and query sources, CSV format options, compression, existing-file protection, and AbortSignal cancellation. See the CSV Export user guide.

await driver.exportToCsvFile('MY_SCHEMA.MY_TABLE', '/absolute/path/to/data.csv');

This release also fixes fetch commands to use the configured fetch size and increases the default fetch size to 1 MiB. Thanks to @espenhogbakk for reporting this!

0.3.1: Minor logger update / CI tests update

Exasol Driver ts 0.3.1, released 2025-06-17

Code name: Minor logger update / CI tests update

Summary

• Reduced logger verbosity in trace mode to prevent potential leakage of sensitive information in trace statements.
• Improved error messages for certain connection issues.
• Updated CI tests to use Exasol Docker DB v8 with encryption enabled in Node.js context:
  • Browser-based CI tests use Exasol Docker DB v7.1.x without encryption.
  • Node-based CI tests use Exasol Docker DB v8.30.x with encryption.
• Currently, encryption testing is not possible with Exasol Docker DB v7.1.x due to incompatibilities with its SSL version.
• Enabling encryption in browser-based CI tests using Docker DB v8 will require a completely new approach. CI test infrastructure will need to be partially re-engineered to support this.
• Due to time constraints this will be implemented at a later date. A separate ticket has been created for this task.

Features

• #21: Add Exasol 8 to integration test
