tedious-plus

This package provides promises, an AsyncIterator and conveniences for Tedious, the SQL Server driver for Node.js.

This is an unofficial add-on package. It is not affiliated with the Tedious project.

Status: Early version. The API is incomplete and may change.

Features

Implemented so far:

• Some promisified connection functions.
• AsyncRowIterator: Reads the result rows of a Tedious Request with a for await loop.

Planned:

• Promisified versions of all database operations that a typical application needs.
• More utility and convenience functions.
• A connection pool.

API layers

The API of this package is organized in layers. Each layer builds on the layer below it. The layers can be combined, and the Tedious API can still be used directly where needed.

• AsyncRowIterator (lowest layer): An AsyncIterator for the result rows of a Tedious Request.
• ConnectionPromises: Promisified functions for a Tedious Connection, e.g. connect(), execSql() and execSqlIterator(). They take Tedious Connection and Request objects as parameters.
• ConnectionPlus (highest layer, planned): A class that wraps a Tedious connection and provides convenient methods. Most applications will only need this layer.

Usage

import * as Tedious from "tedious";
import {ConnectionPromises} from "tedious-plus";

const connection = new Tedious.Connection({
   server: "localhost",
   authentication: {
      type: "default",
      options: {userName: "myUser", password: "myPassword"}
   },
   options: {database: "myDatabase"}
});

await ConnectionPromises.connect(connection);
try {
   const request = new Tedious.Request("select name from sys.databases", () => {});
   const iterator = ConnectionPromises.execSqlIterator(connection, request);
   for await (const row of iterator) {
      console.log(row);
   }
} finally {
   await ConnectionPromises.close(connection);
}
