    SQLc is the perfect tool for those who don't like ORMs

    SQLc is an efficient tool for developers who prefer writing raw SQL queries over using ORMs. It allows for type-safe SQL query generation, fitting neatly within the repository design pattern. SQLc supports multiple programming languages (TypeScript, Kotlin, Python, and Go) and SQL engines (Postgres, MySQL, SQLite). It eliminates boilerplate code, making database interactions more manageable and reusable across codebases. By using SQLc, developers can maintain full control over queries while ensuring type safety and reducing development time.

    Why is gRPC so much faster than a JSON-based REST API?

    gRPC is faster than a JSON-based REST API primarily due to its use of HTTP/2 and Protobuf. HTTP/2 reduces request wait times through asynchronous requests and connection reuse. Protobuf, being binary-based, is more compact and faster during serialization/deserialization compared to JSON. While gRPC offers significant performance benefits, it also introduces complexities in load distribution, troubleshooting, and managing contracts. It's recommended for scenarios needing high performance and capable of handling its complexities, though REST + JSON remains a viable option.

    Protobuf

    Binary encodings like Protobuf offer a compact and efficient way to serialize data, addressing the verbosity and parsing complexities of formats like JSON and XML. Protobuf, created by Google, uses a schema-driven approach to ensure both backward and forward compatibility, making it ideal for performance-critical applications. The process involves defining data structures in .proto files, which are then compiled into code for serialization and deserialization. Proper handling of fields and types in Protobuf protects against breaking changes in evolving schemas.
