How to use the default function from form-data

form-data.default is a module that provides a way to construct HTTP requests with form data in Node.js.

How does form-data.default work?

form-data.default is a module for constructing HTTP requests with form data in Node.js. It provides an easy way to construct and send HTTP requests with form data, including file uploads. The module provides a FormData class, which you can use to create a new form data object. You can then add fields to the form data object using the append method. Each field can have a name and a value, which can be a string, a buffer, or a readable stream. You can also add files to the form data object using the append method, providing a name, a file buffer, and an optional file name. Once you have constructed your form data object, you can use it to create an HTTP request using a Node.js HTTP client library such as http, https, or request. To do this, you create an options object with the request details, including the HTTP method, the URL, and any headers or other options required by the client library. You can then pass the form data object as the request body. When the request is sent, the form data is serialized and sent as the request body. The format of the serialized form data depends on the HTTP client library being used, but it is typically either multipart/form-data or application/x-www-form-urlencoded. Overall, form-data.default provides an easy and flexible way to construct and send HTTP requests with form data in Node.js.

const FormData = require("form-data");
const fs = require("fs");
const fetch = require("node-fetch");

const form = new FormData();
form.append("name", "John");
form.append("email", "john@example.com");
form.append("avatar", fs.createReadStream("/path/to/avatar.jpg"));

fetch("https://example.com/profile", {
  method: "PUT",
  body: form,
  headers: form.getHeaders(),
})
  .then((res) => {
    console.log(res.status);
  })
  .catch((err) => {
    console.error(err);
  });

In this example, we first create a new FormData object using new FormData(). We then add three fields to the form data object using the append method: name and email, which have string values, and avatar, which has a file buffer value created using the fs module. We then use the fetch function, which is a popular HTTP client library in Node.js, to send a PUT request to https://example.com/profile. We set the request body to the form data object using the body option, and set the request headers to the form data headers using the headers option, which we get using the getHeaders method of the form data object. When the request is sent, the form data is serialized and sent as the request body in multipart/form-data format, including the file upload. If the request is successful, the response status code is logged to the console. If there is an error, the error is logged to the console.
