Cache

Nubo caches parsed .nubo server files to avoid re-tokenizing and re-parsing the same file on every request.

What Is Cached

The server caches parsed AST nodes for executable .nubo files.

app/
  index.nubo

When / is requested, index.nubo is parsed and cached.

Cache Duration

The cache duration is 5 minutes.

After 5 minutes, Nubo parses the file again.

File Hash Validation

Nubo hashes the file content.

If the file changes, the hash changes and the cache is ignored.

That means a cached file is reused only when:

Condition	Required
Cache entry exists	yes
File hash matches	yes
Cache has not expired	yes

Development Mode

When serving a directory in development mode, Nubo reloads the router on each request.

nubo serve app --dev

This helps route file changes become visible while developing.

Cache Logs

In development request logs, cached responses may be shown with:
