Why VibeCoding?

  • Rapidly prototype playful webapps without heavy ceremony
  • Use just enough structure—find your creative flow
  • Data and logic where you want them (client, server, or both)
  • Encourage collaboration and creative learning
  • Ship fast, have fun, learn a ton!

Kickoff: Architecture Is a Vibe

  • Keep things simple, but intentional
  • “Dumb” backend? Sometimes smart!
  • Data can live in frontend—spreadsheets, downloads, local files
  • Secure by design: less sensitive data = less to protect

VibeCoding Patterns

  • Start with sketches: whiteboard, napkin, draw.io, whatever!
  • Decide data flow early (arrows over boxes)
  • Minimal persistence: export/import files, not always a full database
  • When backend is needed, make it lean and focused

Code Example

# "Vibe" function: stream data from frontend
def handle_upload(file_contents):
    process_data(file_contents)
    return "All done!"

Simple, collaborative, easy to audit.

def test_output():
    assert handle_upload("foo") == "All done!"

The Method Matters

  • Flow feels great—but test, audit, and repeat!
  • Closed cycles: plan → build → test → document
  • Regular quick audits (humans and AI!)
  • “Buddy review” style—catch issues and learn together

Discipline = Freedom

  • Process lets you go wild and stay safe
  • Small habits, big payoffs
  • Creative vibe is best protected by little rituals

Dual Columns: Choices

  • Frontend persistence (user files)
  • Super fast to build
  • Backend persistence (database)
  • Needed for real-time, multi-user features

Tips & Tricks

  • Comment code, even just a line!
  • Use “build, test, deploy” scripts
  • Let copilots riff, then review carefully
