Saving Image from URL using Node.js

I have been creating a scraper and need an automation to download some images. I spend hours to finally get it right. So, here I am writing this post, hoping that it would help someone in needs (or even future me finds this from search engine).

There may be a lot of other way, but here's the one that works for me today.

const fs = require('fs');
const fetch = require('node-fetch');

const url = "https://www.something.com/.../image.jpg"

async function download() {
  const response = await fetch(url);
  const buffer = await response.buffer();
  fs.writeFile(`./image.jpg`, buffer, () => 
    console.log('finished downloading!'));
}

Please note that fs is included in the node framework, while node-fetch may need to be installed first.

You can combine this with any scraper library like puppeteer.
