A Hacker News clone in Clojure

hsnews

A Hacker News clone written in Clojure using Noir.

Created for Hacker School batch[2].

Example

A live version is viewable at http://news.hackerschool.com. Login on this site is restricted to Hacker School students and alumni.

Usage

First install leiningen

brew install leiningen

Clone this repository and run

lein deps
lein ring server

By default, new user registration is disabled. If you want to enable user registration, uncomment the relevant lines in src/hsnews/views/common.clj and src/hsnews/views/user.clj.

Deployment

Deployment specific code for dotcloud is included in src/hsnews/db.clj to load environment variables. If a DOTCLOUD_DATA_MONGODB_URL variable isn't present, then the site falls back to using a local mongodb database.

There is also the ability to use an external server for authentication. By default, users are authenticaed against the local database. If an AUTH_URL environment variable is present then that URL will be used for authentication.

Self Posts

Self posts are one of the best features of HN.

HSN API

I've already got some fun ideas for things to do with the API, and I imagine others do as well.

Edit Posts/Comments

This might be two feature requests, but I don't want to open that many issues at once.

It would be great if you could edit Post titles/URLs and Comment text.

Links in comments should be clickable

Vim keyboard shortcuts

I want j and k to move between stories on the front page and return to view it.

Add [link, parent, story_name] to each comment in /newcomments

Something like:
username | time elapsed | link | parent | story_name
akin to HN's /newcomments view: http://news.ycombinator.com/newcomments

post with link "www.weathernao.com" redirects to the wrong page

I created a post with the link www.weathernao.com (my new super cool and simplistic weather app!), but the link generated by HSN is http://news.hackerschool.com/www.weathernao.com (which leads to a 404 page).

Validate submitted URLs

I think this could go either way, but it might be nice to do some basic validation on urls or automatically add "http://" or at least warn users when they are about to submit a relative link (if you think that will be a common thing).

Slow like a banshee

Looks like it is loading super slowly, on a heroku instance that needs to spin up or what?
