How can I post a GIF image to twitter using Twit library? - node.js

Question

I am trying to build a small bot that posts random GIFs to twitter based on a hard-coded category (for now).
I am using Twit library for making posts to twitter using the Twitter API. How can I post a GIF to twitter?
Here's the code :
var twit = require('twit');
var config = require('./config');
var request = require('request');
var fs = require('fs');
var path = require('path');
const GIPHY_API_KEY = 'API-KEY';
const GIPHY_API_URL = 'http://api.giphy.com/v1/gifs/random? api_key='+GIPHY_API_KEY+'&tag=study';
var T = new twit(config);
getAndPostGifImg();
function getAndPostGifImg() {
request(GIPHY_API_URL,function (error,response,body) {
var resp = JSON.parse(body);
var img_url = resp.data.image_url;
console.log(img_url);
// post the image to twitter
postImg(img_url);
});
function postImg(img_url) {
request(img_url).pipe(fs.createWriteStream('images/imgpost.gif'));
var filename = path.join(__dirname,'/images/','imgpost.gif');
var params = { encoding: 'base64' };
var img = fs.readFileSync(filename,params);
T.post('media/upload', { media_data: img }, onUpload);
function onUpload(err,data,response) {
var id = data.media_id_string; console.log(id);
// post a tweet /hashtag along with image
var tweet = { status: 'random Study Tweet #giphyBotTweets', media_ids: [id] };
T.post('statuses/update',tweet, tweeted);
}
function tweeted(err,data,response){
if(err)
{
var errors = data.errors;
var i = 0;
for(i = 0 ; i < errors.length; i++)
console.log("Error Message(s) : "+errors[i].message);
}
else
{ console.log(data.text); }
}
}
}
Thanks in advance.

T.post(
"media/upload",
{
media_data: dataImage,
command: "APPEND",
media_id: data.media_id_string,
segment_index: 0
},
function(err, data2, response2) {
T.post(
"media/upload",
{ command: "FINALIZE", media_id: data.media_id_string },
function(err3, data3, response3) {
let tweet = {
status: post.caption,
media_ids: [id]
};
T.post("statuses/update", tweet, function(
err,
data4,
response
) {
if (err) console.log("Something Went wrong", err.message);
if (data4.errors) {
console.log(
"ERROR On Success : ",
data4.errors[0].message
);
} else {
let update = {status: 2, TwitpublishId: data.media_id, updatedAt: Date.now() },
options = { new: true };
Post.findByIdAndUpdate(post._id, update, options, (error, result) => {
if (error) return;
console.log('result video========twit',result);
console.log("Posted on Twitter : https://twitter.com");
});
}
});
}
);
}
);
}
);
}
