Could you describe what you’re trying to do, when the error occurs and what you have tried to fix it?

[itelo]

hey @domoritz, I am having the same issue

In my case, the problems occur when I use the types from React.

run.ts

import { resolve } from "path";
import * as TJS from "typescript-json-schema";

const compilerOptions = {
  "target": "es5",
  "module": "esnext",
  "moduleResolution": "node",
  "resolveJsonModule": true,
  "lib": [
    "dom",
    "es2017",
    "es2015"
  ],
  "types": [
    "react"
  ],
  "declaration": true,
  "jsx": "react",
  "sourceMap": true,
  "strict": true,
  "strictNullChecks": false,
  "noImplicitAny": true,
  "esModuleInterop": true,
  "baseUrl": "./",
  "outDir": "lib",
};

// optionally pass argument to schema generator
const settings: TJS.PartialArgs = {};

const program = TJS.getProgramFromFiles([resolve("src/Elements/Button/interface.ts")], compilerOptions);

const generator = TJS.buildGenerator(program, settings);

generator.getSchemaForSymbol("ButtonInterface");

ButtonInterface with react

import React from 'react';

export type ButtonInterface = 
React.ButtonHTMLAttributes<React.ReactNode> & 
 {
  className?: string;
  text?: string;
  full?: boolean;
  small?: boolean;
  outline?: boolean;
  noUnderline?: boolean;
}

ButtonInterface without react

export type ButtonInterface = 
 {
  className?: string;
  text?: string;
  full?: boolean;
  small?: boolean;
  outline?: boolean;
  noUnderline?: boolean;
}

Excellent. Those details will help with debugging if someone wants to pick this up. For now, I suggest that you increase the stack size for node to or try https://github.com/vega/ts-json-schema-generator.

[itelo]

@domoritz thank you for your quick answer, I tried to increase the stack size but now I got this error:

[1]    7595 segmentation fault (core dumped)  node --stack_size=14000 test.js

I tried to use ts-json-schema-generator before, but when I add react I got:

Error: Unknown node "JSXElementConstructor<any>" (ts.SyntaxKind = 167) at .....

I also comment at issue #209

[domoritz]

Thanks for trying. I don’t have the cycles to look into your specific case right now but I hope you find a solution that works for you.

[cdaringe]

i have this issue too. i think it may have something to do w/ recursive types, which are now permitted in typescript?

i debugged and found the stack exploding trying to model Window :|

   [NUMERIC_INDEX_PATTERN]: this.getTypeDefinition(arrayType)

[cdaringe]

i moved my typedef as follows out of the compile tree, and it began working again:

export type ExtendedWindow = (typeof window) & {
  someRandomGlobalOnTheWindow: bool
}

slap that little buddy into this and watch her break down!

[domoritz]

That’s a super useful test case. Thanks for sharing it.

[phaux]

Repro:

interface Test {
  children: TestChildren;
}

type TestChildren = TestChild | Array<TestChild | TestChildren>;

interface TestChild {
  type: "child";
}

npx typescript-json-schema tsconfig.json Test --include repro.ts

Works with really advanced React types! Check it here https://github.com/Guidewire/ts-to-json-schema-tests/blob/main/schemas/typescript-json-schema-ExampleProps.json

yeah it's huge and you (we) probably don't want it but at least it works
