Install

npm:

npm install lipo

yarn:

yarn add lipo

Usage

To keep things simple you can use the exact same API that Sharp offers.

const lipo = require('lipo');
lipo('input.jpg')
 .resize(300, 300)
 .toFile('output.jpg', err => {
   if (err) throw err;
   console.log('resized image');
 });

Lipo is a drop-in replacement for Sharp (so you won't have to worry about cross-platform installation).

You can simply replace instances of sharp with lipo:

-const sharp = require('sharp');
+const lipo = require('lipo');
-sharp('input.jpg')
+lipo('input.jpg')
  .resize(300, 200)
  .toFile('output.jpg', err => {
     if (err) throw err;
     console.log('resized image');
  });

You can even use Lipo from the command line:

curl -F "input=@/Users/me/Desktop/input.jpg" \
  -F 'queue=[ [ "resize", 300, 300 ] ]' \
  -o /Users/me/Desktop/output.jpg \
  https://api.lipo.io

Resize Method Options: If you need to use constant values such as sharp.kernel.nearest, sharp.gravity.centre, or any other option from resize, please use the alternate form of Lipo.kernel.nearest and Lipo.gravity.centre, respectively (just as an example)

Rate Limiting

Note that if you use make more than 100 requests per hour from the same IP address or wish to exceed 20MB file upload size limitation, we will rate limit you until you sign up for an API key at https://lipo.io.

Once you sign up for a key, you can pass it as const lipo = require('lipo')({ key: 'YOUR_API_KEY_HERE' }); or as an environment variable (e.g. LIPO_KEY=YOUR_API_KEY_HERE node app.js).

Background

While building Lad I was instructing our team how to install Sharp, but there was a lot of confusion with libvips and many cross-platform installation issues.

Between Docker, Ubuntu, and Mac cross-platform issues reported by the team, I wanted to drop Sharp completely as a dependency from Lad.

I tried pure JavaScript-based solutions like Jimp, and even tried PhantomJS and Puppeteer solutions, however they were all too slow.

Sharp was the fastest option, and therefore I thought making a drop-in replacement that uses a powerful server would be satisfactory.

Thus Lipo was born.

Deploy Yourself

See the test folder for an example that shows how to use the middleware lipo-koa (also see lipo-express and other related packages below).
