Platypub

ALPHA NOTICE: Platypub is still in an early state and is in need of a rearchitecture. Breaking changes imminent.

A blogging + newsletter platform. Platypub is basically (1) a CMS, with (2) integrations for Netlify (for hosting your site) and Mailgun (for sending your newsletter) and (3) an extremely flexible theme system. Platypub can run as a multi-tenant managed service (e.g. as opposed to Ghost/Wordpress, where each user must have their own instance), or you can self-host it or even run it locally. It's meant to combine the convenience of e.g. Substack with the flexibility of a static site generator. I also want to add data import/export integrations, so you can e.g. publish your social media posts on your website, or automatically cross-post your articles to social media.

Platypub is not ready for general use yet. When it is, I'll host a public instance of it (with usage-based pricing and a free tier).

Platypub is built with Biff, a Clojure web framework. If you're a Clojurist and you'd like to contribute, see the roadmap for a list of good first issues.

Getting started

Prerequisites:

  • JDK 11 or higher
  • clj
  • Babashka (bb should be on your path)
  • (Optional) API keys for Netlify, S3, Mailgun, and Recaptcha (see config.edn and secrets.env). You can run Platypub without these, but most of the features won't be available.

Run the following:

cp config.edn.TEMPLATE config.edn
cp secrets.env.TEMPLATE secrets.env
cp themes/deps.edn.TEMPLATE themes/deps.edn

Run bb generate-secrets and paste the output into secrets.env. Also edit config.edn and secrets.env as needed.

Then you can start Platypub with bb dev. After you see a System started message, the app will be running on localhost:8080. Once you've signed in, you can create a site, a newsletter, and some posts as described in the default theme setup.

Create a website

  1. Go to Sites and click "New site"
  2. Go to Newsletters and click "New newsletter"
  3. Create the following pages for the new site:
  • One with path: / (home page)
  • One with path: /subscribed (page shown to people after they subscribe to your newsletter)
  • One with path: /about (page linked to in the navigation bar by default)
  • One with path: /welcome and tags: welcome (email sent to people after they subscribe to your newsletter)

Then you can go to Sites and click "preview." If you want to set a custom domain, you'll need to do it from Netlify's website, then update the URL field on the site config page.

Create a custom theme

  1. Copy themes/default to themes/mytheme (or whatever)
  2. Edit/move all the files under themes/mytheme so they use a unique namespace instead of com/platypub/themes/default
  3. Edit the default.clj file (or whatever you renamed it to) and change the :label key at the bottom to something unique.
  4. Edit themes/deps.edn and add themes/mytheme as a local dependency.
  5. Edit config.edn and add the fully-qualified symbol for your theme's plugin var to :com.platypub/themes
  6. Go to Sites -> click on your website, then change the theme setting to your new theme.

While developing your theme, you'll need to do cd themes/mytheme; bb css to make the css file update.

Deployment

You don't need to deploy Platypub to use it. You can run it locally, since any sites you create will be hosted externally on Netlify anyway. However if you'd like to deploy it for convenience, uncomment the :com.platypub/allowed-users and :com.platypub/enable-email-sigin config keys first.

See the Biff docs for deployment instructions.
