Start a usable local instance, including Neo4j, the backend, the frontend, and an automatically provisioned administrator:

docker compose up

Then open http://localhost:3000 and sign in with the default local password multiforum-local-admin. No Auth0, cloud storage, maps, email provider, or manual Cypher bootstrap is required. See the local self-hosting quick-start before customizing credentials or exposing any service beyond your machine.

Multiforum is a community platform that lets people create and manage topic-based forums with multiple content types:

• Discussions — upvotable posts with threaded comments
• Events — with calendar views and map-based discovery
• Wikis — collaborative docs with revision history
• Downloads — file sharing with custom filters per forum

Key differentiators:

• Cross-posting lets content be shared across multiple forums
• Map integration for location-based event discovery
• Personal libraries for organizing favorites and collections
• Granular moderation at both channel and server levels

Multiforum is split across two repositories:

• This repository — the Vue/Nuxt frontend (and its Nitro server layer for SSR and auth).
• gennit-project/multiforum-backend — the GraphQL API and Neo4j data layer.

The frontend talks to the backend exclusively through GraphQL.

Backend architecture: the data model, GraphQL schema, and resolver design are documented in depth in the backend's architecture overview and the references linked from it. This README and the frontend architecture doc cover the frontend and the cross-tier auth flow; for anything about how data is stored, related, and queried, start with the backend docs.

These are the main technologies and, more importantly, why they fit a cross-posting, deeply-interconnected community platform. If you have never used them, the short version of each explains what problem it solves here.

Nuxt is a framework on top of Vue that adds server-side rendering (SSR) — the first version of a page is built on the server and sent as ready-to-read HTML, then "hydrated" into a live app in the browser. That matters here for three reasons:

• Discoverability/SEO. Forum posts, events, and wikis are public content people share and search for. SSR means crawlers and link previews see the real content, not an empty shell waiting for JavaScript.
• Fast first paint. Users see content immediately instead of a spinner, which matters on a content-heavy, link-driven site.
• Hydration-safe auth. SSR lets us render the correct logged-in/logged-out UI on the server using lightweight auth-hint cookies, avoiding the "flash of wrong UI" that plagues purely client-side auth. (See Architecture and authentication.)

Nuxt's file-based routing also maps cleanly onto the many nested routes a forum app needs (/forums/[forumId]/discussions/[discussionId], etc.).

Multiforum's data is fundamentally a graph, not a stack of independent tables. A single discussion can be cross-posted into many forums; comments nest arbitrarily deep; users connect to forums through roles; moderation issues link content, actions, and suspensions together. In a relational database, "show me every forum this download appears in" or "walk this comment thread" turns into a pile of join tables and recursive queries.

Neo4j stores data as nodes and relationships directly, so those traversals — follow the edges between connected things — are natural and efficient. The shape of the database mirrors the shape of the product.

Because the data is a graph, the API is too. GraphQL lets the frontend ask for exactly the connected data a screen needs — a discussion with its channels, author, and comment counts — in a single request shaped like the result. Apollo Client adds a normalized cache so repeated views of the same entity stay consistent and fast without manual bookkeeping.

Auth0 is a managed authentication provider. Rather than building and securing our own login, password reset, and social/single-sign-on flows, we delegate that to Auth0 and focus on the product. It pairs with the SSR auth-hint strategy above to keep login state correct across server and client.

• Pinia — small, typed store for UI state that several components share (theme, modals, navigation) without prop-drilling.
• Tailwind CSS — utility-first styling with first-class dark-mode support, which keeps the large component library visually consistent.
• Google Maps — powers location-based event discovery and clustering.
• Vitest + Vue Test Utils for unit tests and Playwright (with mocked GraphQL) for end-to-end flows — fast feedback locally and in CI.
