Hostr is a project I started almost ten years ago when I set out to learn web development. Since then it's seen over 100,000 signups and served up over 2 billion file downloads.
It has been through many iterations, but in its current incarnation Hostr uses [Koa](http://koajs.com/) for the backend, [Angular](https://angular.io/) and [JSPM](http://jspm.io) for the frontend, and [Babel](https://babeljs.io/) for both.
Currently tested and runs on iojs 2.5.0, probably works on earlier releases and on node. Does yet not work on iojs > 3 due to the NAN changes introduced.
`FILE_HOST` - used by API for absolute file urls, defaults to `$BASE_URL`
`API_URL` - defaults to `/api`
`PORT` - defaults to `4040`.
`VIRUSTOTAL` - API key enables Virustotal integration.
`SENTRY_DSN` - DSN enables Sentry integration.
Additionally, Hostr uses [debug](https://github.com/visionmedia/debug) so you can use the `DEBUG` environment variable something like `DEBUG=hostr*` to get debug output.
### Deploying to Heroku
Because it uses iojs and graphicsmagick runtimes hostr needs an env variable for `BUILDPACK_URL` set to `https://github.com/ddollar/heroku-buildpack-multi.git`.
You'll also need to add Heroku Redis and a MongoDB addon.
My primary motivation is to get to work on Hostr in public. Contributions are welcome and all Javascript is MIT licenced, however the brand is not. The brand includes the name, logo images, CSS and marketing HTML.
