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.

JSON Data Generator
I've been using Fake your JSON-Schemas! (json-schema-faker.js.org), but it does not consider if-then-else rules in its generation process.

[Nestia] Boost up your NestJS server much faster and easier (maximum 20,000x faster)
JSON serialization is 200x faster than class-transformer

How can I declare, integrate a JSON (or similar type that is supposed to be data sent from a server) file into my Angular app, and use it;s data to display the array of Devices within it?
Also OP can check out class-transformer + class-validator if he want to properly instantiate objects and validate them with precise and verbose output of potential format errors. OP can even go the god tier way by setting up a custom RxJS operator that does that for him easily.

Is there a simpler way to cast a complex object into a simpler object?
My two cents: class-transformer it will require to use decorators in your code, but it can handle more cases
