Try this ,
const MongoClient = require("mongodb").MongoClient;
const uri ="mongodb+srv://user:userpassword#meanapp-srlw9.mongodb.net/test?retryWrites=true";
const client = new MongoClient(uri, { useNewUrlParser: true });
client.connect(err => {
const collection = client.db("test").collection("devices");
// perform actions on the collection object
console.log("connencted");
client.close();
});
For now, change your cluster setting to connect from anywhere

I am trying to connect to mongodb replica sets from mongoose following https://mongoosejs.com/docs/connections.html#replicaset_connections
I was able to connect using below syntax in #1 but it throws the errorUnhandledPromiseRejectionWarning: MongoError: not master and slaveOk=false
I looked at other posts with similar error and tried #2 and #3 but the database connection fails altogether,can some provide guidance on how to connect to replica sets without throwing the below error?
#1
mongoose
.connect(
"mongodb://username:password#replicaset1:replicaset1port/myDB", { useNewUrlParser: true }
)
#2:
mongoose
.connect(
"mongodb://username:password#replicaset1:replicaset1port,replicaset2:replicaset2port,replicaset3:replicaset3port/myDB?replicaSet=rsName", { useNewUrlParser: true }
)
#3
mongoose
.connect(
"mongodb://username:password#replicaset1:replicaset1port,replicaset2:replicaset2port,replicaset3:replicaset3port/myDB", { useNewUrlParser: true }
)
Error:-

I'm trying to have a spreadsheet interact with node js and I'm having connectivity issues. I don't quite know where I'm going wrong and I can't seem to find a remedy to my situation. My code is below and it is a mix of Twilio and what I've found here:
const GoogleSpreadsheet = require('google-spreadsheet');
const creds = require('./credentials.json');
// spreadsheet key is the long id in the sheets URL
async function accessSpreadsheet() {
const doc = new GoogleSpreadsheet('XXX');
await doc.useServiceAccountAuth({
client_email: creds.client_email,
private_key: creds.private_key,
});
await doc.loadInfo(); // loads document properties and worksheets
console.log(doc.title);
const sheet = doc.sheetsByIndex[0]; // or use doc.sheetsById[id]
console.log(sheet.title);
console.log(sheet.rowCount);
}
accessSpreadsheet();
I'm new to JavaScript so I don't really know how to properly handle these errors. My error messages are below:
(node:15432) UnhandledPromiseRejectionWarning: TypeError: doc.loadInfo is not a function

I am trying to set up chrome-launcher to output all console messages to terminal. My code looks like this
const chromeLauncher = require('chrome-launcher');
const CDP = require('chrome-remote-interface');
(async function() {
async function launchChrome() {
return await chromeLauncher.launch({
chromeFlags: [
'--window-size=1200,800',
'--user-data-dir=/tmp/chrome-testing',
'--auto-open-devtools-for-tabs'
]
});
}
const chrome = await launchChrome();
const protocol = await CDP({
port: chrome.port
});
const {
DOM,
Network,
Page,
Runtime,
Console
} = protocol;
await Promise.all([Network.enable(), Page.enable(), DOM.enable(), Runtime.enable(), Console.enable()]).catch(console.log);
// REMARKS: messageAdded is fired every time a new console message is added
Console.messageAdded((result) => {
console.log(result);
});
})();
I copied some of this from the question here: How to get console.log output in Terminal via Headless Chrome Runtime.evaluate
When I try to navigate to a page, none of the console messages show up in the terminal, and the chrome-launcher exits with the following error:
(node:14531) UnhandledPromiseRejectionWarning: Error: connect ECONNREFUSED 127.0.0.1:64656

When the code below is executed it opens chrome and the search bar is filled already with this data;,. I haven't mentioned it anywhere in the code still this happens.
Moreover, there are few errors that appear each time I try to run the code.
var webdriver = require('selenium-webdriver'),
By = webdriver.By,
until = webdriver.until;
var driver =new webdriver.Builder()
.forBrowser('chrome')
.build();
driver.get('http://www.google.com/ncr');
driver.findElement(By.name('q')).sendKeys('wiki');
driver.findElement(By.name('btnG')).click();
driver.wait(check_title,1000);
function check_title(){
var promise = driver.getTitle().then((title)=>{
if(title === 'wiki - Google Search'){
console.log('success!');
return true;
}else{
console.log("failed!!");
}
});
return promise;
}
I get this error

How can this be removed?
Use .clear(); to clear the input field for the search bar before you send keys to it. For details on what it does see the answer to this question.
The Promise is not handling the reject with a catch. Following the answers from another question on promise rejection.
var promise = driver.getTitle().then((title)=>{
if(title === 'wiki - Google Search') {
console.log('success!');
return true;
} else {
console.log("failed!!");
}
}).catch(function () {
console.log("Promise Rejected!");
});
