I am working on a little project to learn how to work with APIs by making GET requests to the Twitter API v2 via a node server.
For the get requests I am using Node’s built in https package.
I made a basic GET request that returns a list of the last 10 tweets from a user. I think in order to increase the amount of tweets I can get I have to make a separate parameter object, which I then implement in the get request.
Right now my function looks like this:
function getTweets() {
const options = {
host: "api.twitter.com",
path: `/2/users/${userId}/tweets`,
headers: {
authorization:
`Bearer ${bearerToken}`,
},
};
https
.get(options, (response) => {
let data = "";
response.on("data", (chunk) => {
data += chunk;
});
response.on("end", () => {
let jsonObject = JSON.parse(data);
tweetObjects = jsonObject.data;
tweetObjects.map((item) => {
let tweetWords = "";
tweetWords += item.text;
userTweets.push(tweetWords);
});
const result = userTweets.flatMap((str) => str.split(" "));
console.log(result);
});
})
.on("error", (error) => {
console.log(error);
});
}
Right now I only have the options
object with host, path, and headers in the request.
This is what I am trying to do:
function getTweets() {
const options = {
host: "api.twitter.com",
path: `/2/users/${userId}/tweets`,
headers: {
authorization:
`Bearer ${bearerToken}`,
},
};
let params = {
max_results: 100,
};
https
.get(params, options, (response) => {
let data = "";
response.on("data", (chunk) => {
data += chunk;
});
response.on("end", () => {
let jsonObject = JSON.parse(data);
tweetObjects = jsonObject.data;
tweetObjects.map((item) => {
let tweetWords = "";
tweetWords += item.text;
userTweets.push(tweetWords);
});
const result = userTweets.flatMap((str) => str.split(" "));
console.log(result);
});
})
.on("error", (error) => {
console.log(error);
});
}
But I get
throw new ERR_INVALID_ARG_TYPE('listener', 'Function', listener);
^
TypeError [ERR_INVALID_ARG_TYPE]: The "listener" argument must be of type function. Received an instance of Object

Answer
You can either only pass the URL or an object containing options as stated in the docs: https://nodejs.org/api/https.html#https_https_get_url_options_callback
So you might want to try something like this:
function getTweets() {
let params = {
max_results: 100,
};
const options = {
host: "api.twitter.com",
path: `/2/users/${userId}/tweets?max_results=${params.max_results}`,
headers: {
authorization:
`Bearer ${bearerToken}`,
},
};
https
.get(options, (response) => {
let data = "";
}
