How to download an image with node-fetch

Updated

node-fetch is a great package that allows you to use the wonderful fetch API in server-side Node.js. It can also be used to request and download images from a URL to the local filesystem!

Here's how you do it, assuming that you have node-fetch already installed ( by running npm install node-fetch).

const fs = require('fs') // Built-in filesystem package for Node.js
const fetch = require('node-fetch')

const imageUrl = 'https://via.placeholder.com/350x150'

fetch(imageUrl)
.then(res =>
res.body.pipe(fs.createWriteStream('./path/to/image.png'))
)

This downloads the image at imageUrl and "pipes" (downloads) it to the given path.

Note: Make sure that the folder you're downloading into exists already. If it doesn't, you'll want to create the folders required by doing something like:

const fs = require('fs')

fs.mkdirSync('./path/to', { recursive: true })
