| // Usage | ||
| // ----- | ||
| // The module exports one entry point, the `resovlejson()` function. It takes in | ||
| // the JSON that has id/ref that you want to render as a single argument and returns JSON | ||
| // with whatever graph cycles that are in the document. Note that typically you can't | ||
| // fully expand the json as its a graph. But when navigating via the + sign it is what | ||
| // you would expect. | ||
| // | ||
| // There are two use cases, | ||
| // the first is microsoft's encodes it's graphs with $id $ref, to avoid cyclic graphs | ||
| // (or just to save space). This is resolved renderjson(resolvejson("$id","$idref", ... | ||
| // | ||
| // the second is for json schema's they encode their graphs with id $ref | ||
| // These can be resolved by renderjson(resolvejson("id", "$ref", ... | ||
| var resolvejson = (function () { | ||
| var resolvejson = function resolvejson(idProp, refProp, json) { | ||
| let byid = {}; //dictionary to keep the reference objects | ||
| (function collectObjIds(o) { | ||
| if (o.hasOwnProperty(idProp)) { | ||

| byid[id] = o; | ||
| } | ||

| collectObjIds(o[i]); | ||
| } | ||
