Next.js and Supabase provide many of the building blocks required for a modern SaaS application.
Next.js handles the application interface and server-side functionality, while Supabase can provide database, authentication, storage, and realtime services.
Start With Authentication
Create signup and login flows with Supabase Auth. Each user should have a unique authenticated identity.
Create User Profiles
Add a profile table for application-specific information. Connect each profile to the authenticated user's ID.
Create Your SaaS Data Model
Think about what your SaaS actually manages. For example: Workspaces Projects Tasks Customers Subscriptions Create relationships between those records.
Add Row Level Security
Users should only access the workspaces and data they are authorized to access. Use RLS policies to enforce those rules at the database level.
Build the Dashboard
Next.js can display the authenticated user's projects, settings, and other application data.
Add Storage if Needed
If users upload documents or images, use Supabase Storage and protect the files with appropriate policies.
Deploy the SaaS
Once the application is tested, deploy the Next.js application and configure its production environment variables.
With Hostwares, you can deploy the application and also run the full self-hosted Supabase stack when you want your backend infrastructure on dedicated resources.
