Hi everyone,

Feedback is welcome on this!

I found a way to Tweet using the Twitter API v2 leveraging on node-twitter-api-v2 module using a free tier app (Tweets - post up to 1500 Tweets per month)

1. App Setup on Twitter
Ensure you have set up your Twitter App correctly in the https://developer.twitter.com/en/portal/apps
You need to attach the app to a project. You need also the following credentials:

  • appKey: 'API Key',
  • appSecret: ' API Key Secret',
  • accessToken: 'Access token',
  • accessSecret: 'Access Token secret'

2. Twitter-api-v2 module import in node-red
Import the module in node-red: twitter-api-v2 in the setup tab by adding twitter-api-v2 with the + - this creates a module called twitterApiV2

3. Usage
Use the lib as twitterApiV2 in your code :

const Twitter = twitterApiV2.default;

4. Sample flow (please change the credentials, or find a better secured way to send them to the API):

hello, I like the solution you made!
I would like to ask how it can be solved if it is a gif or mp4 and the image can be handled and uploaded

It does allow to post media

try {
const result = await client.v2.tweet({
text: tweet,
media: { media_ids: mediaIds }
});

// Play with the built in methods
const user = await readOnlyClient.v2.userByUsername('plhery');
await twitterClient.v2.tweet('Hello, this is a test.');
// You can upload media easily!
await twitterClient.v1.uploadMedia('./big-buck-bunny.mp4');
