React

Detection

Uffizzi will detect your repository as a React app if it has any of the following files at its root:

• package.json for NPM projects
• yarn.lock for Yarn projects

Execution

In order of precedence, Uffizzi will execute the following commands if their configurations are present:

1. Procfile buildpack will execute web command if present
2. NPM buildpack will execute npm start (With NODE_ENV=production) if a start command is present in package.json

Troubleshooting

If Uffizzi cannot auto-detect your app, try one of the following troubleshooting methods:

• Remove package-lock.json, then try building again
• Build and import your own Docker image
