Frequently Asked Questions

How much memory should I allocate?

Start with 4GB (4096). For very large projects, you might need 8GB or more.

Why does it happen with many pages?

Each page needs to be held in memory during SSG. More pages = more memory.

Related Problems

Slow Initial Page Load

Your page takes too long to display content, hurting user experience and SEO.

Module Not Found Error

Your bundler can't find a module you're trying to import, causing build failures.
