Instagrammer

Instagrammer lets you fetch Instagram user info and posts. This is done by crawling the Instagram web interface, powered by Capybara and a headless Chrome Selenium driver. Automated integration tests are run daily to keep up with possible changes. Read more about the motivation to build this gem.

Build Status Gem Version Maintainability Test Coverage

Installation

Add this line to your application's Gemfile:

gem 'instagrammer'

And then execute:

$ bundle

Or install it yourself as:

$ gem install instagrammer

If you're running on Heroku, make sure to use the heroku-buildpack-google-chrome buildpack.

Usage

User

Create a new user with Instagrammer::User.new("username") or simply Instagrammer.new("username").

Accessing certain properties on an account that is private will result in a PrivateAccount exception. In some cases Instagram doesn't expose any meta data through. In these cases a UserInvalid exception will be raised when accessing certain properties.

Therefor you can check if the account is scrapable with the #public? instance method.

Metadata

The meta counts data is available for both public as well as private accounts:

user = Instagrammer.new("richardvenneman")
user.follower_count # => "204"
user.following_count # => "141"
user.post_count # => "91"

Bio

Bio info is currently available for public accounts only:

user = Instagrammer.new("richardvenneman")
user.name # => "Richard Venneman"
user.username # => "@richardvenneman"
user.avatar # => "https://www.instagram.com/static/images/ico/favicon-200.png/ab6eff..."
user.bio # => "πŸ‘¨πŸ»β€πŸ’» Partner at GoNomadic B.V.\nTraveling and building πŸ™ @cityspotters"
user.url # => "https://www.cityspotters.com/"

Posts

Get the posts for a specific user by using the #get_posts(_limit_) user method.

user = Instagrammer.new("richardvenneman")
user.get_posts(3) # => [#<Instagrammer::Post:70223732051200..>, #<Instagrammer::Post:70223732051200..>, #<Instagrammer::Post:70223732051200..>]

See below for the available post methods

Post

Create a new post with Instagrammer::Post.new("shortcode").

post = Instagrammer::Post.new("Bg3VjfwDRDw")
post.photo? # => true
post.caption # => "πŸŒ‹ Mount Agung as seen from πŸŒ‹ Mount Batur just after sunrise πŸŒ…"
post.upload_date # => #<DateTime: 2018-03-28T11:07:26+00:00 ((2458206j,40046s,0n),+0s,2299161j)
post.comment_count # => 3
post.like_count # => 52
post.image_url # => "https://instagram.foem1-1.fna.fbcdn.net/vp/04bffab7e91872110690173cbac1ba28/5D9FDCD0/t51.2885-15/e35/29416707_933709783459981_1377808440356765696_n.jpg?_nc_ht=instagram.foem1-1.fna.fbcdn.net"
post.image_urls # => [{:url=>"https://instagram.foem1-1.fna.fbcdn.net/vp/b962b338f5024309e3242ec3e4158681/5DA27835/t51.2885-15/sh0.08/e35/s640x640/29416707_933709783459981_1377808440356765696_n.jpg?_nc_ht=instagram.foem1-1.fna.fbcdn.net", :width=>640}, {:url=>",https://instagram.foem1-1.fna.fbcdn.net/vp/fb1477d8dc17c9d1a6b36c8107b4a5b2/5DC4FA35/t51.2885-15/sh0.08/e35/s750x750/29416707_933709783459981_1377808440356765696_n.jpg?_nc_ht=instagram.foem1-1.fna.fbcdn.net", :width=>750}, {:url=>",https://instagram.foem1-1.fna.fbcdn.net/vp/04bffab7e91872110690173cbac1ba28/5D9FDCD0/t51.2885-15/e35/29416707_933709783459981_1377808440356765696_n.jpg?_nc_ht=instagram.foem1-1.fna.fbcdn.net", :width=>1080}]

Additionally video posts are somewhat supported as well. Image URLs and like counts are not available for videos.

post = Instagrammer::Post.new("Byx0Nd3A3qr")
post.video? # => true
post.watch_count # => 8035142

Motivation

The problem with scrapers is that they always brake. Instagram/Facebook seems to put in a lot of effort to battle scrapers. This gem tries to approach that challenge a bit different than other Ruby Instagram scrapers. With decent test coverage the integration should be tested continuously and good code quality should allow for quick and easy updates may any changes in the Instagram web interface happen.

The main focus is currently retrieving user posts with some metadata while maintaining a stable implementation. Therefor I try to avoid naive page selectors and rely on meta data where possible.
