sqip-loader

SQIP Loader

Loads images and exports tiny SQIP previews as image/svg+xml URL-encoded data

Requirements for non-64bit operating systems

• Golang.
• Primitive.

Install

npm install --save-dev sqip-loader

Usage

The sqip-loader loads your image and exports the url of the image as src, the image/svg+xml URL-encoded data as preview, and a dimensions object containing width, height and the type of the imported image.

import { src, preview, dimensions } from './image.png';

webpack.config.js

module.exports = {
  module: {
    rules: [
      {
        test: /\.(gif|png|jpe?g)$/i,
        use: [
          {
            loader: 'sqip-loader',
            options: {
              numberOfPrimitives: 20
            }
          }
        ]
      }
    ]
  }
};

It can also be used in conjunction with url-loader or file-loader.

webpack.config.js

module.exports = {
  module: {
    rules: [
      {
        test: /\.(gif|png|jpe?g)$/i,
        use: [
          {
            loader: 'sqip-loader',
            options: {
              numberOfPrimitives: 20
            }
          },
          {
            loader: 'url-loader',
            options: {
              limit: 8192
            }
          }
        ]
      }
    ]
  }
};

Options

Name	Type	Default	Description
numberOfPrimitives	{Number}	20	SQIP works by first approximating the image with a certain number of shapes, specified by numberOfPrimitives, and then adding a blur effect to it. Larger values will generate sharper previews, but will also increase the size
mode	{Number}	0	Specifies the type of primitive shapes that will be used to generate the image. 0=combo, 1=triangle, 2=rect, 3=ellipse, 4=circle, 5=rotatedrect, 6=beziers, 7=rotatedellipse, 8=polygon
blur	{Number}	12	Specifies the standard deviation of the Gaussian blur
skipPreviewIfBase64	{Boolean}	false	If set to true, will not generate a preview if the image already is base64 encoded. Useful when the inlined base64 representation is enough, and you don't want to bloat your files with unused previews
