Composer in Drupal 8. Displaying latest tweets from Twitter.

To install modules and libraries in Drupal, it is best to use Composer. Composer is a dependency manager that automatically installs required libraries when installing a module. Although Composer makes module installation slightly more complex, it simplifies managing external libraries since it downloads and connects them automatically.

To install Composer, go to the official site:

https://getcomposer.org/download/

If you've installed Drush via Composer, then Composer is already installed. To verify Composer is installed, run:

composer --version

You should see the Composer version as confirmation.

Displaying Latest Tweets in Drupal 8

First, create a Twitter application and obtain the necessary API tokens at:

https://apps.twitter.com/

Ensure you use API v1.1 or higher, as earlier versions are deprecated. Create your app, and then generate the following:

• Consumer Key
• Consumer Secret
• Access Token
• Access Token Secret

We’ll use the PHP library j7mbo/twitter-api-php to interact with the Twitter API. Install it via Composer:

composer require j7mbo/twitter-api-php

Next, create a custom module in /modules/twitter_block with these files:

twitter_block.info.yml

name: Twitter Block
description: Display Last tweets.
type: module
core: 8.x
package: Custom

TwitterBlock.php (Block Plugin)

<?php

 */
class TwitterBlock extends BlockBase {
  public function build() {
    $config = \Drupal::config('twitter_block.settings');
    $settings = [
      'consumer_key' => $config->get('consumer_key'),
      'consumer_secret' => $config->get('consumer_secret'),

    ];
    $screen_name = 'netglooweb';
    $url = 'https://api.twitter.com/1.1/statuses/user_timeline.json';
    $getfield = "?count=1";
    $requestMethod = 'GET';

    $twitter = new \TwitterAPIExchange($settings);
    $user_timeline = $twitter->setGetfield($getfield)
                            ->buildOauth($url, $requestMethod)
                            ->performRequest();
    $messages = json_decode($user_timeline);
    $content = '';
    if (!empty($messages)) {
      foreach ($messages as $message) {
        $content .= '<div class="twitter-message">' . $message->text . '</div>';
      }
    }
    return ['#markup' => $content];
  }
}
