I Wrote a Python Script That Batch-Publishes to Dev.to

If you're a technical writer who publishes on Dev.to regularly, you know the ritual:

Click "New Post"
Choose your editor
Paste markdown
Set title and tags
Hit Publish
Repeat for the next article...

I got tired of this after publishing a 4-article series. So I automated it.

The Script

import requests, re

s = requests.Session()
s.headers['User-Agent'] = 'Mozilla/5.0 (Linux; Android 14) AppleWebKit/537.36'

# Login
r = s.get('https://dev.to/enter')
csrf = re.search(r'authenticity_token.*?value="([^"]+)"', r.text).group(1)
s.post('https://dev.to/users/sign_in', data={
    'user[email]': EMAIL, 'user[password]': PASS,
    'authenticity_token': csrf, 'user[remember_me]': '1',
})

# Get CSRF for article creation
r = s.get('https://dev.to/new')
csrf = re.search(r'authenticity_token.*?value="([^"]+)"', r.text).group(1)

# Publish
s.post('https://dev.to/articles', data={
    'authenticity_token': csrf,
    'article[title]': 'My Article Title',
    'article[body_markdown]': open('article.md').read(),
    'article[tags]': 'python,devto',
    'article[published]': '1',
})

That's the core. The full version handles error recovery, rate limiting, batch processing, and session persistence.

What I Learned

Dev.to's CSRF system is interesting. The authenticity token on the dashboard works for article creation — you don't need to parse the /new page.

Rate limiting is about 1 post per 30 seconds. The script auto-waits between publishes.
