I'm trying to perform a simple .find() query on my mongodbAtlas, but the result of this query is an empty object.
this is my server file:
require("dotenv").config({ path: "./config.env" });
const { MongoClient, ServerApiVersion } = require("mongodb");
const express = require("express");
const { ServiceBroker } = require("moleculer");
const AUTH_SERVICE = require("./controller/services/auth/auth.service");
global.broker = new ServiceBroker({
nodeID: "auth",
});
const app = express();
app.use(express.json());
app.use("/auth", require("./routes/auth"));
const { PORT, URI } = process.env || 5000;
global.broker.createService(AUTH_SERVICE);
const start = async () => {
const dba = await MongoClient.connect(URI, {
useNewUrlParser: true,
useUnifiedTopology: true,
});
global.db = dba.db("Auth");
try {
await dba.connect();
console.log("DATABASE CONNESSO CON SUCCESSO📡");
} catch (e) {
console.error(e);
}
await global.broker.start();
app.listen(PORT, () => console.log(`PORT IT'S UP AND RUNNING 🚀 ON ${PORT}`));
};
start();
this is my routes file:
const express = require("express");
const router = express.Router();
router.get("/register", async (req, res) => {
const data = global.db.collection("Users").find({}).toArray();
res.send(data);
});
module.exports = router;
this is how my document is populated:
{"_id":{"$oid":"6297bbc83a95b81d74882f65"},"username":"Test","email":"test@gmail.com","password":"1234"}
I think you are missing the "await" keyword after const data..... as API data fetching calls are asynchronous and required promise/ async-await to handle. Being async in nature, it moves forward to the next instruction and returns an empty array.
const express = require("express");
const router = express.Router();
router.get("/register", async (req, res) => {
const data = await global.db.collection("Users").find({}).toArray();
res.send(data);
});
module.exports = router;
