A Mashroom Portal plugin that copies the property 'extraData' from the server user object to the Portal App user

npm install @mashroom/mashroom-portal-app-user-extradata@2.1.2


Mashroom Server


Mashroom Server is a Node.js based Integration Platform for Microfrontends. It supports the integration of Express webapps on the server side and composing pages from multiple Single Page Applications on the client side (Browser). It also provides common infrastructure such as security, communication (publish/subscribe), theming, i18n, storage, and logging out of the box and supports custom middleware and services via plugins.

Mashroom Server allows it to implemented SPAs (and express webapps) completely independent and without a vendor lock-in, and to use it on arbitrary pages with different configurations and even multiple times on the same page. It also allows it to restrict the access to apps based on user roles.

It is even possible to integrate SPAs deployed on a different server (e.g. a different docker container) which allows independent release cycles.

From a technical point of view the core of Mashroom Server is a plugin loader that scans npm packages (package.json) for plugin definitions and loads them at runtime. Such a plugin could be an Express webapp or a SPA or more generally all kind of code it knows how to load, which is determined by the available plugin loaders. Plugin loaders itself are also just plugins, so it is possible to extend the list of known plugin types.

Compared with the concepts in the Java world Mashroom Server would be an Application Server. And the Mashroom Portal plugin has similar concepts than a Java Portal Server such as Liferay.

  • No compile or runtime dependencies to the server
  • Fast and lightweight
  • Portal plugin
    • Build pages from independent SPAs, even written in different technologies
    • Client-side message bus for inter-app communication which can be extended to server-side messaging to communicate with Apps in other browsers or even 3rd party systems
    • Proxying of REST API calls to avoid CORS problems (HTTP, SSE, WebSocket)
