gRPC Foundations
What gRPC is, the RPC model, why it rides on HTTP/2, and how it compares to REST. Start →
gRPC Design — From Zero to Hero
A standalone, beginner→advanced course on designing APIs with gRPC and Protocol Buffers. From the RPC model and protobuf schemas to streaming, deadlines, interceptors, load balancing, security, and gRPC-Web — every topic with the .proto contract and Go, Python, and Node examples side by side.
What you’ll learn
Section titled “What you’ll learn”Protocol Buffers
Messages & field numbers, scalar types, enums, oneof, maps, well-known types, and evolving schemas safely. Model →
Service Definition
Defining services, the four RPC types, designing method signatures, and the error/status model. Design →
Building Services
Code generation with protoc, implementing a server, writing a client, deadlines & cancellation. Build →
Streaming
Server, client, and bidirectional streaming — and the flow control that keeps them healthy. Stream →
Production Concerns
Interceptors, TLS & auth, metadata, load balancing, and health checking. Ship →
Ecosystem & Advanced
gRPC-Web in the browser, REST/JSON transcoding, versioning at scale, observability & testing. Extend →
How this course works
Section titled “How this course works”Contract-first, always
Every lesson starts from the .proto — the language-neutral contract — then shows the generated server and client so you see how the schema drives the code.
Three languages side by side
Server and client examples in Go, Python, and Node (TypeScript) through synced tabs — pick your language once and follow it everywhere.
Design, not just syntax
Every topic covers the why and the trade-offs — when to stream, how to set deadlines, how to evolve a schema without breaking clients.
