Expand Up @@ -395,9 +395,13 @@ Not all Node.js APIs are available. What works:

- `console.log` / `console.info` — fully supported, output visible in Satellite logs and Console UI
- `Math.random()` — supported but seeded once after upgrade, not suitable for lotteries or unpredictable randomness
- `Blob` — immutable raw binary data
- `URL` / `URLSearchParams` — URL parsing and manipulation

No `fs`, `http`, `crypto` from Node, and many npm packages that rely on those will not work. Missing polyfills are added iteratively — open an issue if you're blocked.

> For HTTP calls (`fetch`), use `httpRequest` from `@junobuild/functions/ic-cdk` instead.
