Connecting
The MongoClient connection method returns a Promise if no callback is passed to it. Below is an example using the async
/await
commands.
const MongoClient = require('mongodb').MongoClient;
const assert = require('assert');
(async function() {
// Connection URL
const url = 'mongodb://localhost:27017/myproject';
// Database Name
const dbName = 'myproject';
const client = new MongoClient(url, { useNewUrlParser: true });
try {
// Use connect method to connect to the Server
await client.connect();
const db = client.db(dbName);
} catch (err) {
console.log(err.stack);
}
client.close();
})();
The client.connect
function returns a Promise
that we then execute using the await
keyword inside of an async
function. If an error happens during the client.connect
the error is caught by the try
/catch
and can be handled as if it were a normal Javascript error.
