I\'m not sure what I\'m missing here. I would like to query a MongoDB Database within a Nodejs function. The jobs variable below, keeps returning undefined. I\'

Answer 1

client.connect is async function and accepts callback. You cannot access the jobs variable outside the callback scope.

To do so you can wrap the client.connect method into a function and can return promise from there.

async function getDataFromMongoDB(page) {
  const MongoClient = require("mongodb").MongoClient;
  const uri = "mongodb://localhost:3001";
  const client2 = new MongoClient(uri, { useNewUrlParser: true });
  const client = await connectToMongodb(client2)
  const collection = client.db("meteor").collection("jobs");
  const jobs = await collection.find().toArray();
  console.log("jobs", jobs);
}

connectToMongodb(client) {
  return new Promise((resolve, reject) => {
    client.connect(function(err) {
      return resolve(client)
    });
  })
}
