How do I get the file name in a webpack parser?

I'm working on a plugin that collects exports with a particular name from the modules. I've gotten the data out of the individual files via the parser export hooks, but I can't seem to find out how to pull out the actual module that the parser is operating on.

// hook into the module factory and get the exports
compiler.hooks.normalModuleFactory.tap(pluginName, factory => {
    factory.hooks.parser.for('javascript/auto').tap(pluginName, parser => {
                    parser.hooks.export.tap(pluginName, (node) => {
                        this.parseMetadataNode(node);
                    });
    });
});

parseMetadataNode is the method that does the actual extraction of the export, which is working well.

How do I find the module or userRequest that the node is operating on? I need the file name of that node!

You can probably check parser.state 

compiler.hooks.normalModuleFactory.tap(pluginName, factory => {
    factory.hooks.parser.for('javascript/auto').tap(pluginName, parser => {
         parser.hooks.export.tap(pluginName, (node) => {
           const { module: { rawRequest } } = parser.state;
           // ..
         });
    });
});
