RunJS is a wonderful playground application for testing quickly JavaScript and NodeJS.

MongoDB

👉 MongoDB official note

Setting up the environement variables first.

async function initMongoDb() {
  const uri = `mongodb+srv://${process.env.IDETA_MONGO_USER}:${process.env.IDETA_MONGO_PASSWORD}@${process.env.IDETA_MONGO_HOST}`;
  console.log(uri);
  try {
    const client = await MongoClient.connect(uri, {
      useUnifiedTopology: true
    });
    return { client, db: client.db(`${process.env.IDETA_MONGO_DATABASE}`) };
  } catch (e) {
    throw e;
  }
}

async function testMongo() {
  const mongo = await initMongoDb();
  return mongo.db.collection('agents').findOne({ active: false });
}

async function main() {
  const agent = await testMongo();
  console.log(agent);
}

main();

Lodash

👉 Lodash doc.

var _ = require('lodash');
// and then test with snippets on the doc
_.chunk(['a', 'b', 'c', 'd'], 2);
