Question

I want to read the events of a public google calendar without Oauth authentication. But i can't get a response:

const express = require("express");
const bodyParser = require("body-parser");
const request = require("request");
const app = express();

app.use(express.static("public"));
app.use(bodyParser.urlencoded({
  extended: true
}));


app.get("/", function(req, res) {
  res.sendFile(__dirname + "/index.html");
});




app.post("/", function(req,res){
  request("https://www.googleapis.com/calendar/v3/calendars/XXXXXXXXXXXX.calendar.google.com/events",function(response){

        var calendarSummary = response.summary;
        var calendarDescription =response.description;

        console.log("Response is:");
        console.log("Result is: "+calendarSummary+calendarDescription);
  });
});

app.listen(3000, function() {
  console.log("server is running on port 3000");
});

Any suggestions? Do i need to include an API-key for a public calendar?

I think the issue is your usage of the request library/function. Per the docs The signature for that function is request(error, response, body) , but you only supply one argument. Despite calling it response , it's actually the error object which is probably null . So, change it to the following and I bet it'll work:

request("https://www.googleapis.com/calendar/v3/calendars/XXXXXXXXXXXX.calendar.google.com/events", function(error, response, body) {
  var calendarSummary = body.summary;
  var calendarDescription = body.description;
  console.log("Response is:");
  console.log("Result is: " + calendarSummary + calendarDescription);
});

I think your API call to Google is fine as-is because the documentation says no authorization is needed.
