Why Migrate from GraphQL?

The NestJS tRPC adapter offers a powerful alternative to NestJS & GraphQL. Here's why you might consider migrating:

Key Advantages

1. End-to-End Type Safety Achieve seamless type inference from backend to frontend without code generation, significantly reducing runtime errors caused by type mismatches.

2. Simplified Development Eliminate the need for schema definitions and resolvers. Directly utilize your existing models and business logic, resulting in less boilerplate and faster development cycles.

3. Familiar NestJS Patterns Leverage your existing NestJS knowledge with minimal learning curve, as nestjs-trpc integrates smoothly with the NestJS ecosystem.

4. Performance Benefits Enjoy a lighter-weight solution compared to a full GraphQL implementation, with reduced overhead in request processing and response serialization.

5. Seamless Integration Integrate tRPC alongside your existing NestJS modules and services, enabling a gradual migration path from GraphQL to tRPC.

6. Enhanced Developer Experience Benefit from full IDE support including autocomplete and IntelliSense, easier debugging, and a simplified testing setup compared to GraphQL.

7. Flexible Querying Utilize powerful query composition, including the ability to batch multiple procedure calls in a single HTTP request and support for efficient caching and invalidation strategies.

Migration Considerations

• Learning Curve: Your team will need to familiarize themselves with tRPC concepts, though they are generally straightforward for TypeScript developers.
• Client-Side Updates: Existing client-side code will require updates to use the tRPC client instead of GraphQL queries.
• Feature Parity: Evaluate whether tRPC can fulfill all your current GraphQL use cases before committing to migration.
