MSSQL is a popular npm package that serves as a Microsoft SQL Server client for Node.js. It allows Node.js applications to interact with SQL Server databases, streamline database queries, and enact safe handling of different data types.

How do you use mssql?

Here are some examples of how you can use mssql:

Installation:

npm install mssql

Connect to Microsoft SQL Server using a connection string:

const sql = require('mssql')

async () => {
    try {
        await sql.connect('Server=localhost,1433;Database=database;User Id=username;Password=password;Encrypt=true')
        const result = await sql.query`select * from mytable where id = ${value}`
        console.dir(result)
    } catch (err) {
        // error checks
    }
}

Or, use a configuration object to connect to the database:

const sql = require('mssql')
const sqlConfig = {
  user: process.env.DB_USER,
  password: process.env.DB_PWD,
  database: process.env.DB_NAME,
  server: 'localhost',
  pool: {
    max: 10,
    min: 0,
    idleTimeoutMillis: 30000
  },
  options: {
    encrypt: true, // for azure
    trustServerCertificate: false // change to true for local dev/self-signed certs
  }
}

async () => {
 try {
  await sql.connect(sqlConfig)
  const result = await sql.query`select * from mytable where id = ${value}`
  console.dir(result)
 } catch (err) {
  // ... error checks
 }
}
