## What it is
A pure TypeScript Protocol Buffers implementation with a protoc code-generation plugin and RPC client/server support. It generates typed message classes with binary/JSON serialization, reflection, and clients for gRPC, gRPC-Web, and Twirp.

## Use cases
- serialize protobuf messages in TypeScript
- generate TypeScript code from .proto files
- call gRPC services from a browser
- build a Twirp or gRPC server in Node.js with TypeScript
- handle 64-bit integers with bigint in protobuf
- use proto3 JSON format with strict conformance

## When to choose
- You want type-safe protobuf serialization in pure TypeScript
- You need gRPC, gRPC-Web, or Twirp clients/servers in Node.js or the browser
- You need strict protobuf conformance, reflection, or well-known types support

## When to avoid
- You use JavaScript without TypeScript and don't want generated typed code
- You need protobuf support for languages other than TypeScript
- You need a runtime-only schema-less protobuf decoder without code generation

## Facets
- artifact type: library
- maturity: active
- function: serialization, rpc, http-client
- domain: developer-tools, apis, web-development, backend
- platform: browser, cross-platform
- tags: protobuf, grpc, grpc-web, twirp, bigint, proto3, code-generation, reflection, nodejs, typescript
