## What it is
Tedious is a pure-JavaScript/TypeScript implementation of the TDS protocol for connecting to Microsoft SQL Server (including Azure SQL Database) from Node.js. It provides a slim, low-level driver supporting SQL Server 2000 through 2022 across TDS versions 7.1 to 7.4.

## Use cases
- connect to sql server from node.js
- query mssql database in javascript
- azure sql database driver for node
- run t-sql queries from a node app
- bulk load data into sql server
- pure javascript sql server driver without native dependencies

## When to choose
- you need a dependency-free, pure-JS SQL Server driver for Node.js
- you must support older SQL Server versions (2000-2022) or Azure SQL
- you want a low-level driver to build ORMs or query builders on top of

## When to avoid
- you want a high-level ORM with migrations and models
- you are not using Node.js or SQL Server
- you prefer a driver with native performance optimizations

## Facets
- artifact type: library
- maturity: active
- function: database-driver, database
- domain: databases, backend, developer-tools
- platform: cross-platform
- tags: tds-protocol, sql-server, mssql, azure-sql, pure-javascript, typescript, nodejs
