Nicely done.

From understanding the basics of Protobuf files to decoding raw binary and wiring up custom plugins, you are ready to start building with Protobuf.

Ready to Build?

Protobuf is a deep ecosystem. Here is where to go next.

The full grammar for .proto files, from declarations and field types to options and reserved names.

One binary that compiles, lints, formats, generates code, and catches breaking changes before they ship.

Publish schemas as versioned modules instead of vendoring .proto files, and depend on them from buf.yaml, with hosted docs and generated SDKs.

An RPC framework for gRPC-compatible APIs that also work natively in the browser and on mobile.

Explore Protobuf libraries, runtimes, plugins, and tools from across the community.

Apply the concepts by fixing broken schemas in the interactive exercises.
