Your First Mini App Prompt
Now that you’ve seen how to write effective prompts and where to find help, it’s time to build your first interface. In this section we’ll focus on the visuals: screens, flows, buttons, and layout. No onchain features yet—just getting the look and feel right so you can move fast.Use a split-screen setup if your display allows. Keep Vercel V0 open in
one window for generating UI, and a second window for ChatGPT (or another
LLM) plus a Google Doc for drafting and iterating on your prompt, and
skimming docs as needed. This reduces context switching and speeds up
iteration.
1
Draft your prompt with intent
Start in your notes or a Google Doc. Write a short, focused prompt that
describes the core user journey, key screens, and any visual preferences.
Keep it specific and concise.
2
Set up your workspace
Arrange two windows side by side. Left: Vercel V0 for UI generation. Right:
your LLM and notes for refining the prompt and searching documentation.
3
Generate the first UI in V0
Paste your prompt into V0 and generate an initial interface. Review the
output carefully: layout, component structure, naming, and accessibility.
4
Iterate with fast feedback loops
Identify issues or gaps, refine your prompt, and regenerate targeted parts
(not always the entire UI). Repeat until the flow matches your intent.
5
Export when satisfied
When the interface feels right, download the code from V0. You’ll wire up
functionality and any onchain features later in your local environment.
