Introduction

In the previous tutorial, I built a node js application with the help of twitter lite to add a new tweet to Twitter. You can see the tutorial here.

In this new tutorial, we'll make a similar application to like a tweet, retweet, and follow a twitter user. The new application follows the same structure used in the previous one.

The Application

• As we did in the previous tutorial, We should have 2 files, the first one is config.js that contains twitter lite configurations, and the second file is index.js which contains the following code:

const config = require('./config');
const twitter = require('twitter-lite');
const client = new twitter(config);

• We'll use my twitter account to explain how to like, retweet, and follow. So first, we'll search for my account using twitter API:

// Get twitter user
client.get('users/show', { screen_name: 'ahmed_mahallawy' })
    .then(result => {

    var user = result;
    var latestTweet = result.status;
}).catch(console.error);

• This code makes a get request to 'users/show' endpoint that retrieves user data using my screen name (screen name in twitter is the one preceded by @). You can see full details for this request here.

• We'll save the result in user variable and the user’s latest tweet in latestTweet variable using result.status, so we can use both of them later.

• To like the selected tweet, we'll use a post request to 'favorites/create' endpoint that will add a like to tweet using the tweet id_str attribute:
  

// Like a tweet using its id_str attribute
client.post('favorites/create', { id: latestTweet.id_str })
    .then(result => {

    console.log('Liked tweet successfully!');
}).catch(console.error);

• You can see full details for this request here
• Now, we make a retweet in a very similar way of liking. We'll make a post request to 'statuses/retweet' endpoint that will make retweet using the tweet id_str attribute:

// Retweet a tweet using its id_str attribute
client.post('statuses/retweet', { id: latestTweet.id_str })
    .then(result => {

    console.log('Retweeted successfully!');
}).catch(console.error);

• You can see full details for this request here
• Finally, we follow the user by making a post request to 'friendships/create' endpoint using the user screen name:

// Follow a user using his/her screen_name attribute
client.post('friendships/create', { screen_name: user.screen_name })
    .then(result => {

    console.log('Followed ' + user.screen_name + ' successfully!');
}).catch(console.error);

• You can see full details for this request here
• We wrote all the required code, and now we can run it from cmd using the command:

node index.js

Congratulations!
You did it!!!!!!!!!! 💪

Here's is the full code for index.js file:

const config = require('./config');
const twitter = require('twitter-lite');
const client = new twitter(config);

// Get twitter user
client.get('users/show', { screen_name: 'ahmed_mahallawy' })
    .then(result => {

    var user = result;
    var latestTweet = result.status;

    // Like a tweet using its id_str attribute
    client.post('favorites/create', { id: latestTweet.id_str })
        .then(result => {

        console.log('Liked tweet successfully!');
    }).catch(console.error);

    // Retweet a tweet using its id_str attribute
    client.post('statuses/retweet', { id: latestTweet.id_str })
        .then(result => {

        console.log('Retweeted successfully!');
    }).catch(console.error);

    // Follow a user using his/her screen_name attribute
    client.post('friendships/create', { screen_name: user.screen_name })
        .then(result => {

        console.log('Followed ' + user.screen_name + ' successfully!');
    }).catch(console.error);
}).catch(console.error);

In the following tutorial, we are going to explore more about twitter API. I have several ideas to share with you, so stay tuned 😉
