GraphQL server frameworks do NOT support ad hoc querying out of the box?
Have a look at PostGraphile (in case you are using JavaScript and a PostgreSQL DB). With the advanced connection filter plugin (https://github.com/graphile-contrib/postgraphile-plugin-connection-filter) you get an automatically created filter for multiple items and their connection.

Experiences with GraphQL and ORMs
The postgraphile-plugin-connection-filter I referred to is up-front about the fact that the filters it generates could allow a caller to form queries that would bring your server to its knees. So I'd have to do some work to limit what predicates were allowed.

Don’t we all just want to use SQL on the front end?
More examples here: https://github.com/graphile-contrib/postgraphile-plugin-conn...
(Personally, I think their docs are good at telling you how to use it but fairly bad at showing how great the tool is)
-
Is there a standard or best-practice syntax for passing down "filters" as arguments in GraphQL queries?
I really line the approach used here https://github.com/graphile-contrib/postgraphile-plugin-connection-filter

[DDD] Tactical Design Patterns Part 3: Presentation/Infrastructure Layer
This is the request body when creating a new task. The IsString decorator provided by class-validator rejects all types other than strings, including undefined or null. The task name value object does not consider the possibility of values other than strings.

DRY Principle in Your AWS SAM Application with Middlewares
In this class, we are using the famous class-validator to decorate our request parameters. This way it is more clear how we are going to use our request object and everything.

We add validation using https://github.com/typestack/class-validator.
I will make sure we get this documented.

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.

NestJS GraphQL image upload into a S3 bucket
Start by installing the class-transformer and class-validator packages for dto validation (see more in the docs), sharp for image optimization, and the S3 client packages.

NestJS vs. Ditsmod: auto-validation
The description of the request body model in NestJS is similar to the description of Ditsmod models, but NestJS uses decorators provided by the utility class-validator. In NestJS, it is customary to name the request body model with the ending *Dto (this is an abbreviation of Data transfer object):

Is there any reason not to use typescript?
You could use Zod or Superstruct to validate the types of values, or use typestack/class-validator if it makes sense.

I found 10,000x faster TypeScript validator library
Also, title of before article was I made 1,000x faster TypeScript validator library, but today's benchmark is showing that typescript-json is maximum 6,500x times faster. It's just because I added a new library class-validator in the benchmark and it is much slower than previous zod. Of course, I've continuously tuned the performance, but it just improved the performance about 2x times only.
