## What it is
node-mssql is a Microsoft SQL Server client library for Node.js that provides a high-level API over the pure-JavaScript Tedious TDS driver, with an optional native MSNodeSQLv8 driver. It supports connection strings, config objects, connection pooling, parameterized queries via tagged template literals, and stored procedures.

## Use cases
- connect to sql server from node.js
- run parameterized queries against mssql
- use stored procedures in sql server from javascript
- connect to azure sql database from node
- connection pooling for sql server in node.js
- windows authentication to sql server from node

## When to choose
- your Node.js app needs to query Microsoft SQL Server or Azure SQL
- you want a promise-based API with built-in connection pooling
- you need a pure-JavaScript driver that runs on any OS
- you want safe parameterized queries via tagged template literals

## When to avoid
- you use PostgreSQL, MySQL, or another non-Microsoft database
- you need a driver for a runtime other than Node.js
- you require Windows Authentication without the native msnodesqlv8 driver
