const collection = new MongoDBService(collectionName, connectionOptions);

const result = await collection.find(findQuery, findOptions);

const MongoDBService = require("@devapi/engine/mongodb");

const findOneQuery = { email: "product@domain" };

const findOneOptions = {
  projection: { email: 1 },
};

const collectionName = "contacts";

const connectionOptions = {
  uri: "mongodb://localhost:27017/databaseName",
};

const collection = new MongoDBService(collectionName, connectionOptions);

const result = await collection.findOne(findOneQuery, findOneOptions);

Insert#

Função que permite inserir novo documento no banco de dados MongoDB.

const MongoDBService = require("@devapi/engine/mongodb");

const document = {
