JSON.strigify() breaks with cyclic objects (as per https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Errors/Cyclic_object_value )
The same article recommends 'cycle.js' - which adds 2 methods to the global JSON object - .decycle() & .retrocycle() to stringify cyclic objects.
This works great, but typescript complains unless I add
//@ts-ignore
or other ts hacks - JSON [ 'retrocycle' ] (), etc - which I can do but it's not pretty.
Is there anyway to create something like a "JSON.d.ts" file to override the default TS interface for the global JSON object?
Not sure why this was closed & then re-opened - but by putting together several threads, I came up with this - in case anyone else is interested:
Create a .d.ts typefile, say in src/custom_types:
src/custom_types/JSON.d.ts
In JSON.d.ts:
export declare global {
interface JSON {
decycle(object: any, replacer?: any): string;
retrocycle(something: any): any;
}
}
In tsconfig.json:
{
"compilerOptions": {
...
"baseUrl": ".",
...
"paths" : {
...
"*" : ["src/custom_types/*"],
}
},
"typeRoots": [
....
"src/custom_types/",
],
}
