Node Image Downloader

A Node module for downloading image to disk from a given URL

Install

npm install --save image-downloader

Options

• url (required) - the image URL to download
• dest (required) - the image destination. Can be a directory or a filename. If a directory is given, ID will automatically extract the image filename from options.url (see usage bellow)
• extractFilename - boolean indicating whether the image filename will be automatically extracted from options.url or not. Set to false to have options.dest without a file extension for example. (default: true)
• headers - HTTP headers (default: {})
• timeout - milliseconds before a request times out
• maxRedirects - the maximum number of allowed redirects; if exceeded, an error will be emitted. (default: 21)

For advanced options, see Node.js http.request()'s options documentation

const download = require('image-downloader');

const options = {
  url: 'http://someurl.com/image.jpg',
  dest: '/path/to/dest',               // will be saved to /path/to/dest/image.jpg
};

download.image(options)
  .then(({ filename }) => {
    console.log('Saved to', filename); // saved to /path/to/dest/image.jpg
  })
  .catch((err) => console.error(err));
