Full Stack JavaScript Techdegree Student 15,928 PointsHow can I display my message?
SyntaxError: Unexpected token < in JSON at position 0.
My code:
// Problem: We need a simple way to look at a user's badge count and JavaScript points
// Solution: Use Node.js to connect to Treehouse's API to get profile information to print out
// Require https module
const https = require('https');
const profileName = 'osaroigbinovia';
// Function which prints message to the console
function printMessage (profileName, badges, totalPoints) {
const message = `${profileName} has ${badges} badges and a total of ${totalPoints} points in the JavaScript programme.`;
console.log(message);
}
// Connect to the API URL (https://teamtreehouse.com/username.json)
const request = https.get(`https://teamtreehouse.com/${profileName}`, (response) => {
// Read the data
let body = '';
response.on('data', (info) => {
body += info.toString();
});
response.on('end', () => {
// Parse the data
const profile = JSON.parse(body);
// Print the data
printMessage(profileName, profile.badges.length, profile.points.JavaScript);
});
});

You need to add .json to the url after the profileName variable. Otherwise you are requesting the HTML version of the page.
const request = https.get(`https://teamtreehouse.com/${profileName}.json`, (response) => {
// Read the data
let body = '';
response.on('data', (info) => {
body += info.toString();
});
response.on('end', () => {
// Parse the data
const profile = JSON.parse(body);
// Print the data
printMessage(profileName, profile.badges.length, profile.points.JavaScript);
});
});

Full Stack JavaScript Techdegree Student 15,928 PointsYou're using normal punctuation marks (' ') with interpolation e.g. ${username}, and it doesn't work like that in JavaScript. You need to use template literals i.e. backticks (``) when storing values in a variable you add in your statement(interpolating) e.g.
const message = `${username} has ${badgeCount} total badge(s) and ${points} points in JavaScript`;
`https://teamtreehouse.com/${username}.json`
The backtick key is found just above the 'tab' key on a QWERTY keyboard and also put the 'use strict' statement at the top of all your code.

Full Stack JavaScript Techdegree Graduate 29,312 PointsI am getting the same error but I have .json after my url:
// JavaScript Document
const https = require('https');
const username = "joshbowden2";
function printMessage(username, badgeCount, points) {
"use strict";
const message = '${username} has ${badgeCount} total badge(s) and ${points} points in JavaScript' ;
console.log(message);
}
printMessage("joshbowden2", 100 ,200);
//Connect to the API URL (https://teamtreehouse.com/joshbowden2.json)
const request = https.get('https://teamtreehouse.com/${username}.json', (response) => {
let body = "";
// Read the data
response.on('data', data => {
body += data.toString();
});
response.on('end', () => {
// Parse the data
const profile = JSON.parse(body);
//console.dir(profile);
printMessage(username , profile.badges.length, profile.points.JavaScript);
// Print out info from API
});
});
