dependencyTree only returning an empty object

[kb-ig]

I'm hoping someone can help me understand how to use this, as I seem to be getting an empty object back when using dependencyTree.

I have files along the lines of:

.
└── src/
        ├── file1.js (doesnt depend on anything)
        ├── file2.js (depends on file1.js)
        └── file3.js (depends on file1.js and file2.js)

Above, where I state that a file depends on another, it imports the other file with require().

And I'm trying to get the dependency info like so:

const srcFiles = await fs.readdir('./src/');
const trees = srcFiles.map(filename => dependencyTree({ filename, directory: './src' }));
console.log(trees);

Which outputs:

[ {}, {}, {} ]

Obviously I'm expecting something other than an empty object for each file. If anyone can help me understand how to use this I'd appreciate it.

Are you by any chance on Node.js 20?

@XhmikosR While I cant be sure what I was using back then, I believe it would have been Node 14.

Having just tried to recreate this again now, I get the exact same output on versions 14, 16, 18, 20, 21.

I've created an MRP here.

I expect it's probably me not understanding how to use this library properly.
