post-file.js

#!/usr/bin/env node
const axios = require('axios');
const FormData = require('form-data');
const fs = require('fs');

const filePath = __dirname + '/../accept-http-post-file/cookie.jpg';
fs.readFile(filePath, (err, imageData) => {
  if (err) {
    throw err;
  }
  const form = new FormData();
  form.append('file', imageData, {
    filepath: filePath,
    contentType: 'image/jpeg',
  });
  axios.post('http://localhost:3000/endpoint', form, {
    headers: form.getHeaders(),
  }).then(response => {
    console.log('success! ', response.status, response.statusText, response.headers, typeof response.data, Object.prototype.toString.apply(response.data));
  }).catch(err => {
    console.log(err);
  });
});

Sorry for this super late and likely now useless response ;-). But, yes, if you need to support arbitrary file sizes, you are pretty much forced to use something like createReadStream() on the client and createWriteStream() on the server. Doing this and adding error handling and cleanup gets into a more complicated solution which I would spend time on if I needed to do it myself, but I don’t need to at the moment ;-). Sorry, and I hope that my earlier response was enough to get you somewhere!
