I have a JSON object in my node.js code that contains circular references. To send this information to the browser, I utilized the NPM package circular-json to stringify the object and serialize the circular references:
var CircularJSON = require("circular-json");
app.get("/api/entries", function(req, res){
contentClient.entries({"content_type": "xxxxxxxxxxx"}, function(err, entries){
if (err) throw err;
res.send(CircularJSON.stringify(entries));
});
});
This method works effectively and transmits serialized data via res.send();
Now, I need to make the circular references workable in my frontend Angular code. One of the serialized fields in the object appears like this on the client side: "~0~fields~twitter~1"
I attempted the following steps in the browser:
- Copied a version of
circular-json.jsto my frontend site - Linked the script in my
index.htmlas follows:<script src="/framework/lib/circular-json.js"></script> - Defined the
CircularJsonvariable like this:var CircularJSON = window.CircularJSON; Parsed the incoming JSON like this:
$http.get("/api/entries").then(function(res){ console.log(CircularJSON.parse(res.data[0])); });
However, I encounter the error message:
SyntaxError: Unexpected token o
