protoc-gen-tstypes: Generating types for dependencies

[mousavian]

Consider having this definition:

syntax = "proto3";
import "google/protobuf/timestamp.proto";
service Greeter {
  rpc SayHello(Request) returns (Response) {}
}
message Request {
  string name = 1;
}
message Response {
  google.protobuf.Timestamp date = 1;
}

Inside generated files, it can't resolve timestamp's type from google namespace.

Am I missing anything or I has not been implemented?
Because I didn't see any handler for f.GetDependencies() in the generator.

@mousavian we have a couple of options here. Can you weigh in on how you’d expect it to work?

imported types also fails for protoc-gen-flowtypes for me. What are the options there for types with dependency? @tmc

@shanshanzhu @mousavian the implementation work here isn't hard -- can you propose how you'd expect the output to end up as a design recommendation?

Thanks for this generator, @tmc

There's some info about the canonical JSON mapping:
https://developers.google.com/protocol-buffers/docs/proto3#json

This is what I came up with so far:

declare namespace google.protobuf {
    type Any = {
        "@type": string;
        [index: string]: any
    };
    type Timestamp = string;
    type Duration = string;
    type Struct = { [index: string]: Value };
    type DoubleValue = number | 'NaN' | 'Infinity' | '-Infinity';
    type FloatValue = number | 'NaN' | 'Infinity' | '-Infinity';
    type Int64Value = string;
    type UInt64Value = number;
    type Int32Value = number;
    type UInt32Value = number;
    type BoolValue = boolean;
    type StringValue = string;
    type BytesValue = string;
    type Empty = {};
    type NullValue = null;
    type ListValue = Value[];
    type Value = string | number | boolean | any[] | null;
    type FieldMask = string;
}
