Node.js version compatibility

[henryqdineen]

Should the Node.js version compatibility for React Compiler be documented somewhere? Is it already? I see that there is no engines.node configuration i the package.json but one of the dependencies (zod-validation-error) does expect >=18.0.0.

We are currently using an older version of Node.js with webpack and running into issues with the compiler's usage of Array.prototype.at (supported in >= 16.6.0). It does work with a polyfill but it would be nice to know the official Node.js version compatibility story.

Thanks for posting! This is a good callout, we should document the minimum node version and set engines.node in package.json. A min version of 16.6 seems very reasonable at this point, we could probably be more aggressive and require something newer though.
