Deploy a Create React App site to LeafCloud.

Requirements

Validated with Node v24.22.1, npm 11.19.0, Create React App (react-scripts) 5.0.1, React 19.3.1, and React DOM 19.3.1. Open an existing CRA project that builds with react-scripts build. No static output configuration change is required.

Steps

1. Open the project and move to its root:

   cd <project>

2. No config change is needed.

3. Preview the deployment from the project root:

   leaf deploy --dry-run

   Expected output:

   Framework: Create React App
   Package manager: npm
   Build command: npm run build
   Output directory: build
   Files: 5
   Total size: 1266710 bytes
   Dry run: nothing was uploaded.

What LeafCloud detects

Create React App; npm run build; build.

Common problems

No Create React App-specific refusal was captured in validation.

For agents

Run leaf deploy --dry-run --json first. Check the exit code and stop if the JSON contains "error". After a successful dry run, run leaf deploy --json --yes. Never print credentials.
