Environment Variables

Add environment variables for a project in More Settings › Environment Variables, opened from the project's title menu. They are saved to .env in the project root and added to process.env every time the project runs:

API_KEY=sk-123456

const response = await fetch('https://api.example.com/items', {
  headers: { Authorization: `Bearer ${process.env.API_KEY}` },
});

• .env uses the same format as the Node.js --env-file option. As in Node.js, variables that OneScript already provides (HOME, TMPDIR, USER, PATH, LANG) take precedence, so they can't be set in .env.
• .env is not included when you share a project as a file or a link. It is stored with the project, so it syncs to iCloud Drive when iCloud sync is on.
