Support for inferred types

[jonnyberanek]

Whenever trying to utilize inferred types, this error is thrown:

Error: Unknown node "FirestoreToSerializable<FirestoreService.CreateAuthor>" (ts.SyntaxKind = 184) at C:/proj-path/src/functions/admin/content/body.schema.d.ts(13,36)

After searching, it appears that SyntaxKind #184 is indeed InferType. After looking through the source code it appears that there is not a node parser for inferred types. I'm not too familiar with the inner workings of the project, what kind of additions would be needed to support inferred types?

You need to implement an InferTypeParser and then parse into the right type for it. The easiest way is to create a small test program and then use the debugger to step through the execution and fix where things fail.

Can you please give us some hints on how to implement InferTypeParser? I more or less understand how ts-json-schema-generator works, I have experiences with TypeScript AST, but I have no idea how to resolve inferted types.

Take a look at what properties InferType has.

Then take for example https://github.com/vega/ts-json-schema-generator/blob/master/src/NodeParser/AnyTypeNodeParser.ts. It knows how to handle a particular type, and then generates the correct type (here AnyType).

I haven't thought more about how exactly to handle InferType. That's an exercise fro the reader.

That's an exercise for the reader.

After reading this, I was quite sure that you’re from academia. And hey, you really are! 😄 So do I, sorta.

Hello, fellow academic.

I guess I should clarify that I mean "That's an exercise for the reader" somewhat sarcastically (because many books leave out too many steps when they use the phrase). There are actually a lot of steps left.
