I see too many junior devs trying to implement microservices for a user base of zero. It adds massive complexity with deployment, logging, and data consistency. This item argues for the "Modular Monolith" approach. My proposed architecture for 0 to 100k users:

1. Single Repo: Keep frontend and backend together (Monorepo with Turborepo).

2. Type Safety: Share types between backend and frontend (using tRPC or shared DTOs).

3. Database: Single Postgres instance. Microservices are an organizational solution for massive teams, not a technical requirement for a new app. By the time

For years, Redux was the default, but the boilerplate is exhausting. I’ve migrated three production apps to Zustand, and here is why it’s superior for 90% of use cases:

• Simplicity: No providers wrapping your app. No complex reducers or actions. Just a hook.

• Performance: Selectors allow you to subscribe components to specific parts of the state, preventing unnecessary re-renders.

• DevTools: It still works with Redux DevTools if you need debugging. This contribution includes a code snippet showing a basic "Cart Store" implementation in Zustand vs. Redux Toolkit. The line count difference is

If you are using TypeScript on the backend (Node/Next.js) and TypeScript on the frontend, using REST or GraphQL manually is a waste of time. Enter tRPC. This item demonstrates a setup where your backend function is your API endpoint.

• The Magic: If you change a database column name in your backend, your frontend code immediately turns red (error) in VS Code.

• No Swagger: You don't need API documentation tools because the code documents itself.

• Speed: Autocomplete on the frontend for backend data is a game-changer for development speed. I’ve attached
