Usage

After running the code using npm run start or yarn start open your browser and type localhost:3000, you should see Hello on the screen. To resize an image use the name along with desired height and width for example

http://localhost:3000/api/resize/?file=fjord&width=200&height=200

The new resized image will be returned in the browser and it will be saved at assets/resized as well.
