Migrate to PWA Successfully

Published: 2026-02-20 | Section: Architecture & Platform | Author: Amirreza Rezaie

Today I migrated to PWA and API Gateway successfully.

This is one of the biggest milestones for Goalixa, and I am really happy with the result.

What Is Done

• PWA is now the main frontend entrypoint
• API Gateway is now the main API entrypoint
• Backend traffic is routed through the gateway layer
• Core product flow is now cleaner than before

Current Traffic Flow

Why This Change Is Important

Before this, flow between services was harder to manage because frontend pieces were spread across multiple services.

Now with PWA + API Gateway:

• I can move faster in backend development
• I can extract components and create new microservices easier
• Service boundaries are much clearer
• Future scaling decisions are more flexible

Next Step After This Migration

Now I am ready to:

• Remove frontend codes from Core-API and Auth
• Keep backend services focused on backend responsibility only
• Start designing and adding new backend components as separate microservices

GitOps Status

I am also happy because my GitOps tools are working fine:

• ArgoCD syncs applications correctly
• Harbor stores images in repository as expected

This gives me confidence to continue the migration with safer releases.

Personal Note

Building API Gateway was an amazing experience for me.

At this stage, I feel much more flexible in architecture decisions and much more ready to grow Goalixa with a real microservice mindset.
