connect-from-typescript-and-node

Connects a TypeScript or JavaScript application to Azure SQL Database with the mssql package over tedious: which packages to install, where the connection pool has to live, how to type query results, and how to authenticate with Microsoft Entra ID without a password. Use when a user says "connect my Node app to Azure SQL", "which npm package for SQL Server", "mssql pool size", "passwordless connection from Node", "azure-active-directory-default", "@types/mssql", or reports that a Node API gets slower under load, opens a connection per request, or runs out of connections. Also use when adding a database layer to a Node backend, an Azure Function or an Express route. Covers driver installation, the config object, pool lifetime and Entra ID for this stack only. Encryption doctrine, retry and transient-fault handling belong to connect-to-azure-sql; Python and .NET have their own skills.
