optimizer-image

optimizer-image

This module provides a plugin for the RaptorJS Optimizer and a JavaScript API that allows image info (URL, width and height) to be retrieved on both the server and the client.

Installation

Install the plugin:

npm install optimizer-image --save

Enable the plugin:

require('optimizer').configure({
    plugins: [
        'optimizer-image',
        ...
    ]
})

Usage

The following code can be used to get image info (URL, width and height) on both the server and the client:

var optimizerImage = require('optimizer-image');
optimizerImage.getImageInfo(require.resolve('./my-image.png'), function(err, imageInfo) {
    if (err) {
        // Handle the error 
    }
 
    console.log('URL: ', imageInfo.url);
    console.log('width: ', imageInfo.width);
    console.log('height: ', imageInfo.height);
});

Referenced images will automatically be optimized and written and the URL for the optimized image will be returned. The result is cached (on the server) so there is no performance penalty in making subsequent calls for the same image path.
