Getting Started

Skip self-hosting

Don’t want to run infrastructure? MJ Central is hosted MemberJunction — sign up and start building without standing up a database or API server.

Prerequisites

Self-hosting MemberJunction needs:

• Node.js 20+ and npm
• SQL Server (2019+ / Azure SQL) or PostgreSQL
• A machine to run the MJAPI GraphQL server and the MJ Explorer Angular UI

Install paths

1. Full platform, step by step — the Deployment runbook is the authoritative, battle-tested walkthrough: database provisioning, migrations, CodeGen, MJAPI, and Explorer.
2. Explore the code first — clone MemberJunction/MJ, then read the repo overview for the quick-start commands and the layout of the 290+ packages.
3. Coming from v4? — read Upgrading to v5 before anything else.

Your first hour

• Read What is MemberJunction? — the mental model (metadata → generated everything) in ten minutes.
• Skim the Architecture page to see how the layers fit.
• When your data is flowing, start Building Apps on MJ.
