TypeScript

Requirements

• nodejs v16.0.0
• protobufjs v7.2.3

Test

• Change dir: cd test/ts-tableau-loader
• Install depedencies: npm install
• Generate protoconf: npm run generate
• Test: npm run test

Problems in protobufjs:

• Unable to use Google well known types
• google.protobuf.Timestamp deserialization incompatible with canonical JSON representation
• Implement wrapper for google.protobuf.Timestamp, and correctly generate wrappers for static target.

protobufjs: Reflection vs. static code

If using reflection (.proto or JSON) but not static code, then proto3-json-serializer is a good option.
