proto-gen-tsd v0.0.4

protoc-gen-tsd

Protoc Plugin for generating TypeScript definition

The library exports the protoc-gen-tsd executable, which generates a TypeScript definition file(.d.ts file).

Quick Start

Installation

npm install protoc-gen-tsd

Usage

export PATH ="./node_modules/.bin/:$PATH"
protoc --tsd_out=./examples/protos ./examples/protos/echo.proto
protoc --tsd_out=./examples/protos -I=./examples/protos ./examples/protos/*.proto

Packaging Comparison

Some time ago, gRPC released pure JavaScript implementation of client @grpc/grpc-js without a C++ addon.

The @grpc/grpc-js load package definition object(grpc.loadPackageDefinition) requires a @grpc/proto-loader to load the proto file.

@grpc/grpc-js serialization and deserialization protocol buffer messages depend on the @grpc/proto-loader output package definition object.

When we get the protocol buffer message, it has been deserialized and we can get the information directly from the property accessor.

So, to work with TypeScript you only need to declare the type protobuf message.
