Layzr-Rails

This project integrates the pure vanilla JS Layzr Plugin for Rails image_tag helpers

What's Layzr Plugin?

From the project page:

A small, fast, and modern library for lazy loading images, its written in vanilla JS so don't need any Jquery or other js library.

See live demo.

Documentation

Installation

Add it in your gemfile

gem 'layzr-rails'

Create a configuration file and put it in your initializers config/initializers/layzr.rb

Layzr::Rails.configure do |config|
  config.placeholder = "/assets/some-default-image.png"
end

Add Layzr js and require layzr library in application.js ie:

//= require layzr

And place the javascript code:

$(document).ready(function() {
   const instance = Layzr()
});

Features

  • Add lazy: true option to Rails image_tag helpers to render layzr-friendly img tags.
  • Simple (really). That's pretty much it.

Example

<%= image_tag "kittenz.png", alt: "OMG a cat!", lazy: true %>

Equals:

<img alt="OMG a cat!" data-normal="/images/kittenz.png" src="/assets/some-default-image.png">

More options

<%= image_tag "normal.jpg", lazy: true, layzr: { retina: "retina.jpg", srcset: "small.jpg 320w, medium.jpg 768w, large.jpg 1024w"} %>

Equals:

<img src="/assets/some-default-image.png" data-normal="normal.jpg" data-retina="retina.jpg" data-srcset="small.jpg 320w, medium.jpg 768w, large.jpg 1024w">
