Laravel-Vue post request with data and file via axios?

Question

Vue.js

There is a large form, about 100 fields, input fields of different types, all data is added to the form object, also in this form there is an addition of a file (rar, zip, pdf). It is necessary to send all this to the server with a request for further validation of the server laravel. I'm trying with formData, but the form itself is passed as a [Object] string. Append each field is not an option, because the object has a large nesting structure. Tell me what are the options for transferring data, maybe a link to a tutorial or an example where this is implemented
