Protobuf finally has LSP support. You’re welcome.

Buf is proud to announce the first fully-featured, production-grade LSP server for Protobuf. The Language Server Protocol is the standard API for integrating language support into your favorite IDE or text editor, such as VSCode, IntelliJ, or Neovim. An LSP server provides the smarts that power go to definition, code completion, finding references, and semantics-aware syntax highlighting.

Protovalidate is now v1.0

After two years of development, we're proud to announce that Protovalidate has reached v1.0. Protovalidate is the semantic validation library for Protobuf. Protobuf gives you the structure of your data, but Protovalidate ensures the quality of your data. Without semantic validation, you're stuck writing the same validation logic over and over again across every service that consumes your messages. With Protovalidate, you define your validation rules once, directly on your schemas, and they're enforced everywhere.

Introducing hyperpb: 10x faster dynamic Protobuf parsing that’s even 3x faster than generated code

Today we’re announcing public availability of hyperpb, a fully-dynamic Protobuf parser that is 10x faster than dynamicpb, the standard Go solution for dynamic Protobuf. In fact, it’s so efficient that it’s 3x faster than parsing with generated code! It also matches or beats vtprotobuf’s generated code at almost every benchmark, without skimping on correctness.

Tip of the week #9: Some numbers are more equal than others

The first 15 field numbers are special: most runtimes will decode them much faster than the other field numbers. When designing a message type for decoding performance, it’s good to use these field numbers on fields that are almost always present.

Oneofs are a disaster. Protovalidate has fixed them.

Instead of using oneofs, you can now use the new (buf.validate.message).oneof Protovalidate annotation. As long as you're validating your messages with Protovalidate, (buf.validate.message).oneof does exactly what you'd expect, with none of the pain.

Tip of the week #8: Never use required

Don’t use 'required' to modify fields—you won’t be able to get rid of it later when you realize it was a bad idea.

Get started on the path to universal schema adoption

Define your schema once. Generate SDKs, docs, and dependencies automatically.
