basic fetch

const fetch = (url) => {
    return new Promise((resolve, reject) => {
        https.get(url, (response) => {
            const dataPromise = new Promise((resolve, reject) => {
                const d = [];
                let dlen = 0;
                
                response.on('error', reject);
                response.on('data', (data) => {
                    d.push(data)
                    dlen += data.length;
                })
                response.on('end', () => {
                    resolve(Buffer.concat(d, dlen));
                }) 
            });
            
            const getJson = () => dataPromise.then(data => JSON.parse(data.toString()));
            
            resolve({
                json: getJson
            });
        });
    });
