Post Tweet Using Twitter SDK

Before creating the API endpoint, let's make a script ready that will accept the tweet with the image URL generated using OpenAI and Dall•E model. We will use twitter-api-v2 node package to post the tweet along with the image to our Twitter account. Let's discuss the steps that will be followed to implement the script.

1. Accept the tweet and image URL (optional, since we also have functionality to generate tweets without images).

2. Instantiate a twitter client using the credentials.

3. If the image URL is available, then download the image using the https module from Node.js and save it locally on the server.

4. Use the Twitter client to upload the image and the tweet. First, we need to upload the image using the Twitter client and then attach the uploaded image's id to the tweet as media_ids.

Post the tweet with image using Twitter SDK

As discussed, we will implement a function that accepts the tweet with an optional image URL. We will use a node package twitter-api-v2 to interact with Twitter and post the tweets. The twitter-api-v2 simplifies using the Twitter API by offering features like pre-built wrappersPre-built functions that correspond to specific functionalities in the Twitter API. This saves you time and effort compared to manually building HTTP requests., type safetyLeverages TypeScript for type definitions, which helps prevent errors during development and improves code readability., authentication handlingBuilt-in support for handling different Twitter authentication methods, including OAuth 1.0a and OAuth 2.0., etc. Now, if the image URL is given, then we will download the image using https module by piping the response data to a writeable stream using the fs module. First let's implement a function that accepts an image URL and path to store the image.
