💡 Can executing 'Deno. cwd()' in the worker return an independent directory?

[hanrea]

I want an independent environment for executing workers. I currently treat workers as a lightweight container and hope that each worker has their own directory to handle certain tasks in conjunction with Deno's permission management.
In short, can the program customize the context of the worker.

Deno.cwd() returns the current working directory of the process. Workers run in threads within that process, so no.

You'd have to create another api for the workers to use that could have its own local state for the cwd, or you'd need to or change the Deno global in the worker.

I have solved this problem, and when initializing the runtime, the worker can write the proxy state parameter:

deno/ext/fs/lib.rs

Line 258 in bc8a0e6

state.put(options.fs);

When calling op_fs_cwd, it is possible to return diffent values based on the state parameter
