Obtengo los productos cuando registro en la consola la variable de productos const, pero tengo problemas para insertar datos en la base de datos mongodb y dice que mongoClient no está conectado.
const express = require("express"); const cors = require("cors"); const { MongoClient } = require("mongodb"); require("dotenv").config(); const app = express(); app.use(cors()); app.use(express.urlencoded({ extended: true })); app.use(express.json()); const uri = `mongodb+srv://${process.env.DB_USER}:${process.env.DB_PASSWORD}@cluster0.lgrhg.mongodb.net/${process.env.DB_NAME}?retryWrites=true&w=majority`; const client = new MongoClient(uri, { useNewUrlParser: true, useUnifiedTopology: true, }); client.connect((err) => { const productsCollection = client .db(`${process.env.DB_NAME}`) .collection(`${process.env.DB_COLLECTION}`); console.log("database connected") app.post("/addProduct", (req, res) => { const products = req.body; productsCollection.insertMany(products).then((result) => { console.log(result.insertedCount); res.send(result.insertedCount); }); }); client.close(); }); app.listen(4000);Después de eso, obtuve esto en mi consola:
database connected MongoNotConnectedError: MongoClient must be connected to perform this operation at Object.getTopology (F:\Node-js\2-ema-john-server\node_modules\mongodb\lib\utils.js:389:11) at Collection.insertMany (F:\Node-js\2-ema-john-server\node_modules\mongodb\lib\collection.js:157:61) at F:\Node-js\2-ema-john-server\index.js:26:24 at Layer.handle [as handle_request] (F:\Node-js\2-ema-john-server\node_modules\express\lib\router\layer.js:95:5) at next (F:\Node-js\2-ema-john-server\node_modules\express\lib\router\route.js:137:13) at Route.dispatch (F:\Node-js\2-ema-john-server\node_modules\express\lib\router\route.js:112:3) at Layer.handle [as handle_request] (F:\Node-js\2-ema-john-server\node_modules\express\lib\router\layer.js:95:5) at F:\Node-js\2-ema-john-server\node_modules\express\lib\router\index.js:281:22 at Function.process_params (F:\Node-js\2-ema-john-server\node_modules\express\lib\router\index.js:335:12) at next (F:\Node-js\2-ema-john-server\node_modules\express\lib\router\index.js:275:10)tengo la respuesta :)
simplemente elimine client.close()
¿Puede probar el siguiente fragmento de código y dejarme saber el resultado:
client.connect((err) => { const productsCollection = client .db(`${process.env.DB_NAME}`) .collection(`${process.env.DB_COLLECTION}`); console.log("database connected") app.post("/addProduct", (req, res) => { const products = req.body; productsCollection.insertMany(products).then((result) => { console.log(result.insertedCount); client.close(); res.send(result.insertedCount); }); }); });
