File posting

Axios allows very simple file posting. You can easily submit a single file as below:

await axios.postForm("https://httpbin.org/post", {
  myVar: "foo",
  file: document.querySelector("#fileInput").files[0],
});

You can also submit multiple files:

await axios.postForm(
  "https://httpbin.org/post",
  document.querySelector("#fileInput").files
);

All files are sent as multipart/form-data and you can access them in the server side as you would with any other file upload. All files are sent with the same field name files[].
