ES6 version of profile.js

The code of the video is deprecated, use this version instead. In order to understand EventEmitter, please refers to any video on YouTube explaining EventEmitter in Node.js.

import EventEmitter from 'events';
import { get, statusCode } from 'https';
import { STATUS_CODES } from 'http';

class Profile extends EventEmitter {
    constructor(username) {
        // need for calling the methods of EventEmitter
        let profileInstanceContext = this;

        const request = get(`https://teamtreehouse.com/${username}.json`, res => {
            let body = '';

            if (res.statusCode !== 200) {
                profileInstanceContext.emit('error', new Error(`There was an error getting the profile for ${username}. (${STATUS_CODES[statusCode]})`))

            res.on('data', chunk => {
                body += chunk;
                profileInstanceContext.emit('data', chunk);

            res.on('end', () => {
                if (res.statusCode === 200) {
                    try {
                        // Parse the data
                        const profile = JSON.parse(body);
                        profileInstanceContext.emit('end', profile);
                    } catch (error) {
                        profileInstanceContext.emit('error', error);
            }).on('error', error => profileInstanceContext.emit('error', error));

export default Profile;

This throws an error -

import EventEmitter from 'events';

Another point to notice is that as of 2022, the request URL is wrong, the correct URL to get profiles should now be

let request = https.get(`https://teamtreehouse.com/profiles/${username}.json

Notice that the /profiles/.
