Adding multi-tenancy to your Blitz app

This document is a tutorial giving step by step instructions on how to add multi-tenancy to your Blitz application, using Prisma-multi-tenant.

Step 1: Initialize Prisma-multi-tenant

Download, then run the Prisma-multi-tenant CLI.

npm i -g prisma-multi-tenant

prisma-multi-tenant init

After following the instructions, you will now have a management database set up.

Step 2: Add the Blitz multi-tenant package

npm i @prisma-multi-tenant/blitz

Step 3: Update the Blitz config

Add the multi-tenant middleware into blitz.config.js

const { multiTenantMiddleware } = require('@prisma-multi-tenant/blitz')

module.exports = {
  // ...
  middleware: [
    multiTenantMiddleware((req, res) => {
      // The name can come from anywhere (headers, token, ...)
      return 'dev' // or 'my_tenant_A' or anything
    }),
  ],
}

Step 4: Access the tenant

In your queries and mutations, access the tenant from the context:

export default async function getProjects(args, ctx) {
  const projects = await ctx.db.project.findMany(args)

  return projects
}

And that's done! 🎉

Try adding a new tenant and play between them!

pmt new # Creates a new tenant

pmt list # List your existing tenants

# Access studio to the given tenant
pmt studio my_tenantA
pmt studio my_tenantB
