This is the
source code to the
ghost town at
It is a Rails codebase and uses a SQL (MariaDB in production) backend for the database.
You are free to use this code to start your own sister site
because the code is available under a permissive license (3-clause BSD).
We welcome bug reports and code contributions that help use improve lobste.rs.
As a volunteer project we're reluctant to take on work that's not useful to our site, so please understand if we don't want to adopt your custom feature.
We'd love to have your help.
Please see the CONTRIBUTING file for details.
If you have questions, there is usually someone in our chat room who's familiar with the code.
Use the steps below for a local install or
lobsters-ansible for our production deployment config.
There's an external project docker-lobsters if you want to use Docker.
Install the Ruby version specified in .ruby-version
Checkout the lobsters git tree from Github
$ git clone git://github.com/lobsters/lobsters.git
$ cd lobsters
Install Nodejs, needed (or other execjs) for uglifier
Fedora: sudo yum install nodejs
Ubuntu: sudo apt-get install nodejs
OSX: brew install nodejs
Run Bundler to install/bundle gems needed by the project:
mysql2gem on macOS, you see
ld: library not found for -l-lpthreadin the output, see this solution for a fix. You might also see
ld: library not found for -lsslif you're using macOS 10.4+ and Homebrew
openssl, in which case see this solution.
Create a MySQL (other DBs supported by ActiveRecord may work, only MySQL and
MariaDB have been tested) database, username, and password and put them in a
config/database.yml file. You will also want a separate database for
development: adapter: mysql2 encoding: utf8mb4 reconnect: false database: lobsters_dev socket: /tmp/mysql.sock username: *dev_username* password: *dev_password* test: adapter: mysql2 encoding: utf8mb4 reconnect: false database: lobsters_test socket: /tmp/mysql.sock username: *test_username* password: *test_password*
Load the schema into the new database:
lobsters$ rails db:schema:load
On your production server, copy
config/initalizers/production.rb and customize it with your site's
name. (You don't need this on your dev machine).
Seed the database to create an initial administrator user, the
inactive-user, and at least one tag:
lobsters$ rails db:seed
On your personal computer, you can add some sample data and run the Rails server in development mode.
You should be able to login to
http://localhost:3000 with your new
lobsters$ rails fake_data lobsters$ rails server
Deploying the site in production requires setting up a web server and running the app in production mode.
There are more tools and options available than we can describe; find a guide or an expert.
The lobsters-ansible repo has our config files to crib from. Some app-specific notes:
Set up crontab or another scheduler to run regular jobs:
*/5 * * * * cd /path/to/lobsters && env RAILS_ENV=production sh -c 'bundle exec ruby script/mail_new_activity; bundle exec ruby script/post_to_twitter; bundle exec ruby script/traffic_range'
config/initializers/production.rb.sample for GitHub/Twitter integration help.
You probably want to use git-imerge to pull in
changes from Lobsters to your site.
Basic moderation happens on-site, but most other administrative tasks require use of the rails console in production.
Administrators can create and edit tags at
