Post Longer Content & Longer Videos -- Tutorial

Step-by-step guide to posting extended tweets, long-form articles, and longer videos using XActions with Premium/Premium+ tiers.

Prerequisites

• Logged into x.com in your browser
• Browser DevTools console (F12 -> Console tab)
• X Premium or Premium+ subscription (required for extended limits)
• For Node.js usage: npm install xactions and a valid session cookie

Quick Start

1. Navigate to x.com
2. Open DevTools (F12)
3. Use src/postComposer.js for extended tweets or src/articlePublisher.js for articles
4. Premium subscribers can post up to 25,000 characters per tweet

Posting Extended Tweets

Node.js / Puppeteer

Extended tweets work the same as regular tweets -- just type more text:

import { postTweet } from './src/postComposer.js';

const longText = `This is an extended tweet that goes well beyond the 280-character limit.

With X Premium, you can write up to 25,000 characters in a single tweet. This is useful for detailed explanations, stories, or technical content that would otherwise require a thread.

The full text appears in the timeline with a "Show more" button for viewers.`;

await postTweet(page, longText);

Browser Console

// Open compose dialog
document.querySelector('[data-testid="SideNav_NewTweet_Button"]').click();

// Wait, then type extended content
setTimeout(() => {
  const textarea = document.querySelector('[data-testid="tweetTextarea_0"]');
  textarea.focus();
  document.execCommand('insertText', false, 'Your very long post content here...');
}, 1500);

Extended Tweets vs Threads

Extended tweets display with a "Show more" button in the timeline. Not all users click it, so put your hook in the first 280 characters.

Publishing Articles (Premium+)

Articles are X's long-form content format, similar to blog posts.

Node.js / Puppeteer (src/articlePublisher.js)

import { publishArticle, saveDraft, getArticles } from './src/articlePublisher.js';

// Publish an article
const result = await publishArticle(page, {
  title: 'Why Browser Automation Beats API Access',
  body: `Full article body goes here. Articles support long-form content
with paragraphs, and you can include as much detail as needed.

This is the second paragraph of the article. Unlike tweets, articles
are displayed in a reader-friendly format with proper typography.`,
  coverImage: '/path/to/cover.jpg',  // Optional
});

// Save as draft instead of publishing
const draft = await saveDraft(page, {
  title: 'Draft: Upcoming Feature Analysis',
  body: 'Work in progress...',
});

// List your published articles
const articles = await getArticles(page, 'nichxbt');
console.log(articles);

Article Functions

How Article Publishing Works

1. Navigate to https://x.com/compose/article
2. Click the title input ([data-testid="articleTitle"]) and type the title
3. Click the body editor ([data-testid="articleBody"]) and type the content
4. Optionally upload a cover image via [data-testid="articleCoverImage"]
5. Click publish ([data-testid="articlePublish"]) or save draft ([data-testid="articleSaveDraft"])

Article Features

• Rich formatting: Articles support headers, paragraphs, and text styling
• Cover images: Add a hero image that appears at the top of the article
• Drafts: Save work in progress and return to it later
• Analytics: Track views, likes, reposts, and engagement on your articles
• Shareable: Articles get their own URL and preview card when shared

Uploading Longer Videos

Premium Video Upload (up to 60 minutes)

import { postTweet } from './src/postComposer.js';

// Upload a longer video (Premium accounts)
await postTweet(page, 'Full tutorial walkthrough - 45 minutes of content!', {
  media: '/path/to/long-tutorial.mp4',
});

For large video files, you may need to increase wait times since processing takes longer:

// The default 2-second wait in postComposer.js may not be enough
// For production use, poll for upload completion

Video Best Practices

• Compress first: Use ffmpeg or HandBrake to compress videos before uploading
• Format: MP4 with H.264 video codec and AAC audio codec works best
• Thumbnail: X auto-generates a thumbnail from the first frame
• Captions: Add captions using src/videoCaptions.js for accessibility (see the video captions tutorial)
• Processing time: Large videos can take several minutes to process on X's servers

Extended Content Strategy

When to Use Extended Tweets

• Detailed explanations that lose meaning when split into thread chunks
• Stories or narratives that flow better as continuous text
• Technical documentation or tutorials
• Responses to complex questions

When to Use Threads Instead

• Numbered lists or step-by-step guides
• Content designed for maximum engagement (threads get more interaction)
• Content where each point stands alone
• Building suspense or narrative tension

When to Use Articles

• Blog-style content with structure and formatting
• Content you want discoverable via your profile's Articles tab
• Evergreen content that should be easy to find later
• Long tutorials, guides, or analyses

Tips & Tricks

• First 280 characters matter: Even in extended tweets, the timeline only shows the first ~280 characters with a "Show more" button. Hook readers early.
• Video compression: A 60-minute video at 1080p can be several gigabytes. Compress to a reasonable bitrate (5-8 Mbps for 1080p).
• Article SEO: Article titles appear in search results. Use clear, descriptive titles.
• Draft regularly: For articles, use saveDraft() frequently to avoid losing work.
• Premium check: The script will fail gracefully if Premium features are not available, returning an error message instead of crashing.
