Union types and type intersections don't work together about ts-json-schema-generator HOT 4 CLOSED

Ran into the same problem...

type Base = {
    a: string;
};

type Variant1 = {
    b: string;
};

type Variant2 = {
    b: number;
};

export type MyObject = Base & (Variant1 | Variant2);

It works when restructuring the type a little bit, so this may be used as a workaround:

export type MyObject = (Base & Variant1) | (Base & Variant2);

We should be doing this automatically but it's not trivial to implement with the current architecture.

There seems to be another issue with the original example. Even when translating the intersection type manually to A & {x: true} | B & {x: true} it does not yield the correct schema because the restriction of x to true is ignored. It works when swapping the order to {x: true} & A | {x: true} & B. This has nothing to do with unions, can also be reproduced with a simple intersection. I'll create a new issue for this (See #115).

I'm closing this issue because the main part of it is fixed now by #116. The still remaining issue with objects not being properly merged together is tracked by issue #115.
