  - name: ts
    out: ../src/__generated__/proto
    strategy: all
    path: ../node_modules/.bin/protoc-gen-ts_proto
    opt:
      - esModuleInterop=true     # required
      - unrecognizedEnum=false   # required
      - outputTypeRegistry=true  # required
    strategy: all
  - name: pothos
    path: ../node_modules/.bin/protoc-gen-pothos
    out: ../src/__generated__/pothos
    opt:
      - pothos_builder_path=../../builder
      - import_prefix=../proto

Supported options

import_prefix (string, required)
- path to out dir of ts-proto
pothos_builder_path (string, required)
- path to file that exports pothos builder
emit_imported_files (bool, optional)
- if true, protoc-gen-pothos also emits types defined in imported .proto file.

scalar (string, optional)

add scalar mapping
default:
- Protobuf's 64-bit integer types to String
- Protobuf's bytes type to Bytes
- google.protobuf.Timestamp to DateTime

e.g.

Map google.type.Date to Date
- ```
opt:
  - scalar=google.type.Date=Date
```
  opt:

Map Protobuf's 64-bit integer types to BigInt

opt:
  - scalar=int64=BigInt
  - scalar=uint64=BigInt
  - scalar=sint64=BigInt
  - scalar=fixed64=BigInt
  - scalar=sfixed64=BigInt
  - scalar=google.protobuf.Int64Value=BigInt
  - scalar=google.protobuf.UInt64Value=BigInt
  - scalar=google.protobuf.SInt64Value=BigInt
  - scalar=google.protobuf.Fixed64Value=BigInt
  - scalar=google.protobuf.SFixed64Value=BigInt
