Lee, VP of Product at Vercel, discusses how to get the most out of v0, their AI assistant for web development [00:00:15].
What is v0?
V0 is an AI assistant specifically designed for web development [00:01:08]. It focuses on working with JavaScript, HTML, CSS, and modern frameworks and libraries to produce high-quality web products [00:01:25].
Getting the Most Out of v0
V0 can be used for both UI and backend work [00:03:02].
Tips for UI Development
- Start with screenshots: Providing screenshots is highly effective, especially if you have a specific design in mind (e.g., a Spotify-like UI) [00:03:11].
- Let the AI paint: If you don’t have a clear vision, you can let v0 generate designs and then refine them [00:03:40]. For example, a simple request for a Slack integration page yielded a complete component in one shot [00:03:51].
- Iterative Design: Continue to refine the design through prompts, even if the initial version isn’t perfect [00:04:30]. Examples of iterative prompts include:
- “Make it have warmer Grays” [00:04:56]
- “Use a Sanda font” [00:04:59]
- “Make the UI have a tighter information density” [00:05:12]
- “The time playing bar should be longer” [00:05:18]
- “Add more realistic fake data for the songs” [00:05:24]
- Utilize Tailwind CSS Knowledge: v0 “thinks in Tailwind” [00:06:03]. You can explicitly tell it Tailwind classes (e.g., “make it size four”) to precisely control elements [00:06:09].
- Incorporate Imagery: Adding images significantly improves the visual appeal, as typography and imagery are huge components of web design [00:07:48]. You can upload and paste images for v0 to use in designs [00:06:47].
- Use Natural Language: Talk to v0 as you would a designer (e.g., “the now playing bar is pretty wide”) [00:08:06].
- Leverage CSS Knowledge: If you have CSS knowledge, you can steer the assistant with specific properties (e.g., “tabular nums” for number alignment) [00:08:25].
- Mobile Responsiveness: Simply ask v0 to “make it mobile responsive” [00:08:47]. You can then refine responsive behaviors (e.g., “I can’t see the table of songs because the image is so large, can you fix it?“) [00:09:10].
- Break into Components & Add Logic: After designing, you can ask v0 to break the UI into components and add interactivity [00:09:39].
- Refine Color Schemes: Experiment with different color palettes (e.g., “adjust the color scheme to be darker”) [00:10:03].
- Learn Design Principles: If you’re a design novice, ask v0 questions like “I don’t know how to make my design look better, what can I try?” [00:11:27]. It can provide advice on consistent color schemes, white space, readable fonts (e.g., Sans Serif vs. Serif), and using high-quality images [00:12:11].
- Find Inspiration: Use design inspiration sites like Godly.website [00:14:15] and Patterns [00:15:19]. You can start with screenshots from these sites to get the basic layout or elements right [00:14:45].
- Leverage Shad CN UI: V0 is built on Shad CN UI, which provides component libraries for various patterns (mail app, dashboard, chat, music player, etc.) [00:16:11]. You can fork these components within v0 and customize them for your brand [00:16:48].
- Refine Animations: For slow animations, ask v0 for solutions. It can suggest specific Tailwind animation overrides like faster durations and cubic bezier easing functions [00:25:06].
Tips for Backend Development
- Integrating UI with Backend Logic: Once the UI is built, v0 can help you implement backend functionalities like CRUD (create, read, update, delete) actions [00:19:58].
- API Calls: Swap out mock data with real API calls within your application [00:20:50]. You can provide v0 with an external API schema or database schema (e.g., PostgreSQL) to help it fetch and hook up real data [00:21:04].
- ORM and Database Schema: v0 can generate ORM (Object-Relational Mapping) code (for Drizzle, Prisma in JavaScript/TypeScript, or other languages like Rails/Laravel) based on your PostgreSQL schema [00:21:25]. It can even help design your database by suggesting things like indexes for faster queries [00:23:15].
The Power of AI Tools in Development
AI tools like v0 are not replacing development work; they are augmenting it [00:27:21]. They act like a knowledgeable senior engineer, providing best practices and helping builders bring their ideas to life [00:27:28]. With these tools, builders have the power to create almost anything, from web apps to iOS or Android apps, as the AI understands various programming languages and platforms [00:27:45].
