How does mongodb.Binary work?

mongodb.Binary is a class provided by the MongoDB Node.js driver that represents binary data in a BSON format, and it can be used to store and retrieve binary data in MongoDB. It takes two arguments: a buffer containing the binary data and a sub-type that specifies how the data is encoded.

const { MongoClient } = require("mongodb");
const fs = require("fs");
const mongodb = require("mongodb");
const binary = mongodb.Binary;

const uri = "mongodb://localhost:27017";
const client = new MongoClient(uri, { useUnifiedTopology: true });

async function run() {
  try {
    await client.connect();
    console.log("Connected to MongoDB");

    const database = client.db("mydb");
    const collection = database.collection("mycollection");

    // Read binary data from a file
    const data = fs.readFileSync("/path/to/file.pdf");

    // Insert binary data into MongoDB
    await collection.insertOne({ file: binary(data) });
    console.log("Inserted binary data into MongoDB");
  } catch (err) {
    console.error(err);
  } finally {
    await client.close();
    console.log("Connection to MongoDB closed");
  }
}

run();

In this example, we first create a Binary object from binary data read from a file using fs.readFileSync(). We then use the Binary object to insert the binary data into a MongoDB collection using collection.insertOne().
