Invalid types using @tsconfig/node20

[javialon26]

It looks like extending the tsconfig.json file from @tsconfig/node20 is causing type errors, particularly with the second argument (options) on routes and with parameters like params, body, headers, etc., not appearing in VSCode IntelliSense. However, when you remove the lib: ["es2023"] setting, everything works as expected.

Reference #1749

Packages versions:
"openapi-fetch": "^0.10.5",
"openapi-typescript": "^7.3.0",
"typescript": "^5.5.4"

Generator script:
"generate:client": "openapi-typescript https://petstore3.swagger.io/api/v3/openapi.yaml -o ./src/lib/client.d.ts",

tsconfig.json

{
  "extends": "@tsconfig/node20/tsconfig.json",
  "compilerOptions": {
    "outDir": "./dist"
  },
  "include": ["src"]
}

Example using pet store swagger file and lib: ['ES2023']:

This appears to be broken by a change in [email protected], specifically microsoft/TypeScript#58610, which first shipped in [email protected]. However, the underlying cause is the typing issue noted in #1823.

I can reproduce this issue in a project with:

• typescript@>=5.5
• @types/node@>=18
• tsconfig.json declares (or extends a config with) a lib array that does not include "DOM"
