C++ Faker library
I am currently working with Typescript as well as C++ and I enjoyed using FakerJS library for testing data. I've checked for C++ libraries and I haven't found anything that could be used for my basic needs (like generating emails, passwords, names, uuids or lorem words) so I just started my own project with idea to deliver such library to C++ developers.

How do you get realistic data in your staging databases?
I built a CSV generator which I then use as a test data source for a dsv library on that principle and another API generator based on schema. Something that might be additionally helpful is json-schema-faker, as you can probably convert you primary record (DB schema) to json-schema then just generate tons of data.

Intro to AWS Websockets Part Three: Documentation
The payload object contains a reference to a JSON Schema object that describes the properties of the event. This allows the consumer to know exactly how to define the event when publishing or how to write code that consumes a subscribed event. There are even tools online that generate examples from JSON Schema (and vice versa).

How do you "stitch & glue" types for all your needs?
The class-validator / class-transform looks really nice for formatting/validation but there is also joi. suretype is attractive since theoretically typeconv could generate jsonSchema for json-schema-faker and Open API docs.
