async option is not true async 3.1.10

[crh3675]

We are using 3.1.10 with NodeJS 20.9.0.

I read that there is an async option for rendering templates. Upon further inspection of the source code, this is not a real Async behavior as the internals of this library use these calls to load file data.

• fs.existsSync
• fs.readFileSync

Any hopes to Promisify these calls to be truly async?

@crh3675 can you assign it to me

Can you explain a little more about the use-case here? Rendering is sync anyhow, and template caching is built in. Why is this useful or important?
