Relative paths

If you work with absolute paths, you should get what you expect from memfs.

You can also use relative paths but the gotcha is that then memfs needs to somehow resolve those relative paths into absolute paths. memfs will use the value of process.cwd() to resolve the relative paths. The problem is that process.cwd() specifies the current working directory of your on-disk filesystem and you will probably not have that directory available in your memfs volume.

The best solution is to always use absolute paths. Alternatively, you can use mkdir method to recursively create the current working directory in your volume:

vol.mkdirSync(process.cwd(), { recursive: true });

Or, you can set the current working directory to /, which is one folder that exists in all memfs volumes:

process.chdir('/');
