MongoDB: How to run db.adminCommand() in NodeJS

Problem:

You want to run a db.adminCommand() in NodeJS using the node-mongodb-native client, e.g. you want to run the NodeJS equivalent of

admin_command_example.js
db.adminCommand({setParameter: 1, internalQueryExecMaxBlockingSortBytes: 100151432});

Solution

Use conn.executeDbAdminCommand() where db is a MongoDB database object.

admin_command_example_full.js
db.executeDbAdminCommand({setParameter: 1, internalQueryExecMaxBlockingSortBytes: 100151432});

Full example:

example.js
// To install, use npm i --save mongodb
const MongoClient = require('mongodb').MongoClient;

async function configureMongoDB() {
    // Connect to MongoDB
    const conn = await MongoClient.connect('mongodb://localhost:27017/', { useNewUrlParser: true });
    const db = await conn.db('mydb');
    // Configure MongoDB settings
    await db.executeDbAdminCommand({
        setParameter: 1,
        internalQueryExecMaxBlockingSortBytes: 100151432
    });
    // Cleanup
    return conn.close();
}

// Run configureMongoDB()
configureMongoDB().then(() => {}).catch(console.error)
