The record

Purpose: ts-proto transforms .proto files into strongly typed, idiomatic TypeScript files.
Generated code: Generated message code includes TypeScript interfaces and encode, decode, toJSON, and fromJSON methods.
Service clients: It generates service types and client implementations for Twirp, grpc-web, grpc-js, and NestJS.
Install and use: The quick start installs ts-proto with npm and invokes it as a protoc plugin.
Buf integration: The README documents configuring ts-proto with Buf and says an official plugin is published to the Buf Registry.
Gradle integration: The README documents invoking ts-proto through the protobuf-gradle-plugin.
TypeScript style: The project aims for TypeScript-first, idiomatic output and uses interfaces instead of classes where possible.
Well-known types: It converts Protobuf well-known types, including wrapper and Struct types, to corresponding native TypeScript or JSON types.
Batching: Twirp clients can automatically batch matching individual RPC calls to prevent N+1 calls when the documented batching convention is used.
RPC scope: The project describes itself as RPC-framework agnostic and not an out-of-the-box RPC framework.
Unsupported workflow: It supports code generation from .proto files but does not support runtime reflection or loading of dynamic .proto files.
Unsupported clients: The README says it does not support clients for google.api.http-based Google Cloud APIs.
Support: The maintainer invites companies seeking customizations or priority support to contact him by email.
License: The repository identifies its license as Apache-2.0.
