LazyRender

What is this?

It delays loading of partial or actions in views.

Installation

LazyRender works with Rails 4.0 onwards. You can add it to your Gemfile with:

gem 'lazy_render'

Usage

1. Route to LazyRender

add to routes.rb

  lazy_render_for 'lazy_render/load', to: 'lazy_render'

2. Configuring Javascript

add to application.js

//= require jquery
//= require lazy_render

3. Configuring Controller

add to include helper into application_controller

class ApplicationController < ActionController::Base
  helper LazyRender::LazyloadHelper
end

create a controller to run lazy render

controllers/lazy_render_controller.rb

class LazyRenderController < LazyRender::LazyloadController
  def load
    super
  end
end

and add some action to LazyRenderController

def sample_action(locals)
  @data[:sample_text] = 'Hello LazyRender!'
  @data[:pass_value] = locals[:value]
end

4. Configuring View

create view file under views/lazy_render/

views/lazy_render/sample_action.html.erb

<h2>This is sample view.</h2>
<p><%= data[:sample_text] %></p>
<h3><%= data[:pass_value] %></3>

5. Call lazy_render from View

Call lazy_render from your any views

<%= lazy_render :sample_text, locals: { value: 'Sample Text' } %>

<h2>This is sample view.</h2>
<p>Hello LazyRender!</p>
<h3>Sample Text</3>

lazy_render options

• locals : The parameters to passed to action
• cache : Time to hold a View to the local storage. Default: 0
• callback : To specify the Javascript method that you want to execute after displaying partial.
• parallel : I carry it out in parallel without compiling a request in lazy_render. Default: false
