How to send data with a file from the client (React) and receive it on nodejs?

Question

Node.js

There is a form, regular fields + file attachment
If you do this:

let data = {
    name,
    email,
    title,
    message,
    file: fileInput.current.files["0"],
}
let options = {
    method: "POST",
    headers: {
        "Content-Type": "application/json",
    },
    body: data,
}
fetch("http://localhost:8000/send", {
    options,
}).then(...

Not taking into account the file, the data comes correctly, bodyParser with JSON is installed on the server.
And how to transfer everything, along with the file? Next, I will save the file to the directory with multer.
Somewhere they write that you need to specify 'Content-Type': 'multipart/form-data' , somewhere that you need to remove the headers altogether. Doesn't come out at all

Answer 2

It is very convenient through the react-hook-form the minimum number of renders, well, as mentioned above, it will be necessary to append everything through the formdata
