Roll your own http client

[dapplion]

To remove the dependency node-fetch consider writing an HTTP client to download a Github release asset to disk. Note it must

• Follow N redirects
• Handle networks errors
• Handle fs errors
• Have a timeout
• Retry?

Proposed initial code by @mpetrunic

const https = require('https');
const fs = require('fs');

const file = fs.createWriteStream("./binding.node");
const request = https.get("<release url>", (response) => {
  if(response.statusCode == 302) {
     https.get(response.headers.location, (res) => {
        res.pipe(file);
     })
  } else {
     response.pipe(file);
  }
});
