You jsut need to pick a library that makes cURL requests and away you go.
If using Got, (incomplete sample)
got(
'https://api.twitch.tv/helix/users??id=44322889',
{
headers: {
'Content-Type': 'application/json',
'Client-ID': client_id
},
gzip: true
}
)
.then(resp => {
console.log(resp.body);
Got is documented here
