pdfjs_viewer-rails

Installation

Add this line to your application's Gemfile:

gem 'pdfjs_viewer-rails'

Note: pdfjs_viewer-rails is still in early development. Please report if you encounter any issues along the way.

Viewer Styles

This gem ships with three viewer styles:

full

reduced

minimal

Usage

Using the mountable Engine

The mountable engine makes it extremely simple to integrate the PDF.js viewer into your application:

config/routes.rb

mount PdfjsViewer::Rails::Engine => "/pdfjs", as: 'pdfjs'

Now you can use a link in your templates to open up the viewer:

<%= link_to "display using the full viewer", pdfjs.full_path(file: "/sample.pdf") %>
<%= link_to "display using the minimal viewer", pdfjs.minimal_path(file: "/sample.pdf") %>

Using the helper

If your integration scenario is more complex you may want to consider using the pdfjs_viewer helper. This allows you to embed the viewer into a container like an iframe.

<%= pdfjs_viewer pdf_url: "/sample.pdf", style: :full %>
<%= pdfjs_viewer pdf_url: "/sample.pdf", style: :minimal %>

NOTE: The helper will render a full HTML document and should not be used in a layout.

Development

Tests can be executed with:

$ bundle exec rake

This will render the sample.pdf using phantomjs and save screenshots into test/sandbox.
