Dummy code to inform & discuss the implementation of 3rd party plugins


Extendability was always a crucial feature of the idea behind Hoodie, it’s one of the biggest advantages over closed source or hosted alternatives.

After working on Hoodie for over two years we gained enough understanding of its architecture to rebuild it from the ground up, focusing on maintainability and ease of contribution.

We had to disable plugins and are now working on enabling them again. This repository is meant as a base of discussion for everyone interested to help with its implementation


We can start working on 3rd party plugins for extending client API, the server logic and the web UI immediately. Admin dashboard extensions and background tasks being out of scope for now.

We are trying to finish up these tasks before implementing the plugins to make things easier:


  • hoodie plugins are npm modules. We recommend a hoodie-plugin- package name prefix, but it’s not required. Folder structure:

    ├── package.json
    └── hoodie
       ├── client.js    # or: hoodie/client/index.js
       ├── server.js    # or: hoodie/server/index.js
       └── public
           └── index.html
  • hoodie plugins can extend the Hoodie client, the Hoodie server, provide a web UI for /hoodie/<name> and extend the Hoodie admin dashboard at /hoodie/admin (out of scope). Both hoodie/client and hoodie/server are optional

  • The Server plugin must be loadable via require('hoodie-plugin-foo/hoodie/server'). A Hoodie server plugin is a hapi plugin
  • The client plugin must be loadable via require('hoodie-plugin-foo/hoodie/client') A Hoodie client plugin can be a function or an object, it will be passed into hoodie.plugin()
  • The hoodie/public folder will be exposed at /hoodie/<name> by the server if it exists.
  • The order in which server/client plugins are loaded is
    1. core modules (account, store, task)
    2. 3rd party plugins (npm dependencies)
    3. app plugins
  • hoodie.plugin.foo is passed into the server plugin, hoodie.plugin.foo.client is passed to the client plugin.
  • The hoodie package is automatically loading all server & client modules unless they are disabled with config (hoodie.plugin.foo = false in package.json)
  • When using the @hoodie/server or @hoodie/client packages directly then plugins must be loaded and configured manually.


Loading 3rd party plugins would most likely go into server/plugins/index.js. For comparison see how @hoodie/server is loading @hoodie/store-server and @hoodie/account-server.

Loading the web UIs can work the same way we currently load the public folder of @hoodie/account and @hoodie/store. We need to add a check if the folder exists first

The dynamic bundling of the Hoodie client is implemented in server/plugins/client/bundle.js.

This plugin has hoodie as devDependency. The idea is that plugins can be started just like apps, and if they have a hoodie/public folder it will be served, and the server & client will be extended dynamically (see hoodiehq/discussion#98)
