Quickstart

CLI

Create a form0 project, start the dev server, and open a live preview. This flow uses only the CLI and the default schema template that comes with it.

Prerequisites

Node.js 22.19.0+ - Download here
A terminal or command prompt
Your favorite code editor

Get ready in 5 steps

Build and preview your first form0 schema in minutes.

Install the CLI:
```
Code
npm install -g form0-cli
```
Or run without a global install:
```
Code
npx form0-cli
```
npx command runs the CLI without a global install.
Start the interactive shell:
```
Code
form0
```
Initialize a standard project:
- Run init
- Choose Standard project
- Let the CLI auto-load your schema
If there is only one schema file in the project root, it is loaded automatically.
Start the dev server:
```
Code
form0> serve
```
🎉 That's it! Now your form0 live preview is running at http://localhost:3030 in your browser.

What you get

Standard projects are file-first and CLI-driven.

form.schema.json with a starter form
form0.config.js for CLI settings
test.js for local engine checks
supporting-images/ for field assets
